Direct answer: A hazardous-chemicals procurement and supplier-qualification page is not "the supplier has a business licence". The website page should state: how to decide whether a chemical is regulated (catalogue, SDS, label), which certificates the supplier needs (production/business/safe-use licence, registration, business licence), what is required to buy highly toxic or explosive-precursor chemicals (purchase licence or lawful-use statement), what the contract/order must contain (name, concentration, quantity, use, packaging, transport, emergency), how to store (dedicated location, dual receipt/custody, in/out records), how to transport (dangerous-goods licence, carrier, highly toxic road pass) and how to keep records/file (sales records at least 3 years; filing within 3 days of purchase). On the law: the Hazardous Chemicals Safety Law has been in force since 2026-05-01: the catalogue is determined, published and adjusted by the State Council emergency management department with other departments (Article 3); hazardous-chemicals business is licensed, and a business enterprise may not purchase hazardous chemicals from an enterprise engaged in production or business without a licence (Article 53); enterprises holding a safety production, safe-use or business licence may buy highly toxic or explosive-precursor chemicals with that licence, while other entities buying highly toxic chemicals need a public-security purchase licence and those buying explosive precursors need their own lawful-use statement, and individuals may not buy them (Article 58); sellers of highly toxic/explosive-precursor chemicals must verify licences or statements, keep truthful records for at least 3 years and file with public security within 3 days of sale/purchase (Articles 60 and 61); internet sale/purchase of highly toxic and explosive-precursor chemicals is prohibited (Article 63); hazardous chemicals must be stored in dedicated locations, with highly toxic chemicals and other chemicals constituting major hazard installations stored separately under dual receipt and dual custody, with records kept at least 3 years (Article 41). Information is current to 2026-11-07. This is a review of public rules and page practice, not legal, EHS or procurement advice; the law, catalogue, supporting rules and authority requirements control.
This guide is for procurement, EHS, warehouse, quality, legal and website teams at equipment, electronics/electrical, automotive, medical device, hardware, electroplating, coating, chemical, packaging and export manufacturers in Changzhou and nearby areas. This page most often misses catalogue, licences, purchase formalities, storage, transport and records, ending up as "supplier documents are complete".
First check the catalogue: is it a hazardous chemical, a highly toxic chemical or an explosive precursor; then check the supplier: production/business/safe-use licence, registration, SDS/label; finally the process: purchase licence/use statement, storage, transport, records and filing. The website should state catalogue, qualifications, formalities, storage, transport, records and emergency—not "documents complete".
How does this page relate to supplier onboarding, SDS, transport and EHS pages?
The hazardous-chemicals procurement/qualification page answers "what to buy, from whom, on what authority, and how to store/transport/record"; the supplier onboarding/AVL page answers registration, qualifications, capacity and questionnaires; the SDS/product-safety page answers hazards, labels and customer audits; the dangerous-goods/lithium-battery transport page answers UN numbers, UN38.3, packaging and channels; the safety production/dual-prevention page answers risk grading, inspections and emergency. The procurement page is the entry point for compliant buying; an onboarding or SDS page cannot replace it.
Common breakpoints: only a business licence is collected; the business licence has expired; the supplier is a trader without a hazardous-chemicals business licence; highly toxic chemicals are bought without a purchase licence; explosive precursors are bought without a use statement; SDS is incomplete or the label does not match; storage is not dedicated and lacks dual receipt; an ordinary truck is used; sales records are kept less than 3 years; purchase is not filed; the website publishes customer/supplier sensitive information. Separate "catalogue—qualifications—formalities—storage—transport—records"; then procurement, EHS, warehouse and legal share one playbook.

This page map is editorial; the Hazardous Chemicals Safety Law, catalogue and authority requirements control.
How do you determine whether a chemical is regulated?
First check the Catalogue of Hazardous Chemicals (2015 edition) and later adjustment announcements; the catalogue is determined, published and adjusted by the State Council emergency management department with other departments (Article 3). Note that Announcement No. 3 of 2026 added five chemicals, including 3-chloropropyne, 2-iodoxybenzoic acid, 2-diazoacetoacetic acid 4-nitrobenzyl ester, methanesulfonyl azide and 2-nitro-3-methylbenzoic acid (April 2026, ten departments including the Ministry of Emergency Management). Then check the SDS composition/hazard classification and label; mixtures, concentration and use can change the conclusion. The page should state "catalogue + SDS + supplier confirmation + assessment where needed", not let procurement guess from the product name.
Acceptance checks: catalogue version; 2026 adjustment; SDS; label; mixture; concentration; use; assessment. Common gaps: name only; old catalogue; SDS missing composition; label without hazards; mixture not assessed; concentration unknown.
| Basis | What to confirm | Evidence | Common gap |
|---|---|---|---|
| Catalogue | Name/alias/CAS | Catalogue entry | Name only |
| 2026 adjustment | Five new chemicals | Announcement | Old version |
| SDS | Composition/classification | Supplier SDS | Incomplete |
| Label | Hazards/warnings | Label sample | No marking |
| Mixture | Concentration/components | Formula/statement | Not assessed |
| Use | Restrictions | Process description | Out of scope |
| Assessment | When needed | Report | None |
Catalogue/adjustment follows the official texts; specific entries and classification follow the latest catalogue, SDS and authority determination.
Which supplier qualifications are required?
By role: producers—hazardous-chemicals safety production licence (where applicable), business licence, hazardous-chemicals registration (producers/importers, Articles 85 and 86), SDS/label; traders—hazardous-chemicals business licence (Articles 53–55), business licence; users acting as suppliers—hazardous-chemicals safe-use licence (for chemical enterprises subject to licensing, Article 48); transport—dangerous-goods road transport licence/filing (Article 65). Note: a business enterprise may not purchase hazardous chemicals from an enterprise producing or trading without a licence (Article 53), so the upstream supplier's licence must also be checked. Verify the scope, chemicals, validity and issuing authority, not just a photocopy.
Acceptance checks: role; licence type; scope; validity; registration; business licence; SDS; upstream. Common gaps: business licence only; expired licence; scope excludes the chemical; trader without a business licence; production/business mixed up; no registration; unlicensed upstream.
| Supplier role | Core certificate | Check point | Common gap |
|---|---|---|---|
| Producer | Safety production licence | Scope/validity | Expired |
| Trader | Business licence | Chemicals/storage | None/out of scope |
| User | Safe-use licence | Whether required | Misjudged |
| Carrier | Dangerous-goods road licence | Scope/vehicles | Ordinary truck |
| Registration | Hazchem registration | Producer/importer | Missing |
| Business licence | Entity/address | Consistent | Name mismatch |
| Upstream | Production/business licence | No unlicensed purchase | Not checked |
Qualification types follow Articles 48, 53–55, 65 and 85–86 of the Hazardous Chemicals Safety Law; the licence scope and authority requirements control.
What is required to buy highly toxic or explosive-precursor chemicals?
Enterprises holding a hazardous-chemicals safety production, safe-use or business licence may buy highly toxic or explosive-precursor chemicals with the corresponding licence; other entities buying highly toxic chemicals must apply to the county-level public security bureau for a highly toxic chemicals purchase licence; those buying explosive precursors must hold their own lawful-use statement; individuals may not buy them (with limited exceptions such as highly toxic pesticides and certain daily-use products) (Article 58). Sellers must verify the licence/statement and sell according to the licensed variety and quantity (Article 60); internet sale/purchase of highly toxic and explosive-precursor chemicals is prohibited (Article 63). The page should state who applies, what to submit, how long approval takes, how much and how to describe the use—not "a purchase contract is enough".
Acceptance checks: buyer; licence/statement; variety/quantity; use; authority; deadline; internet ban; records. Common gaps: using a business licence to buy highly toxic chemicals without checking Article 58(1); vague use statement; over-quantity; online inquiry/order; no purchase record.
| Scenario | Formality | Evidence | Common gap |
|---|---|---|---|
| Licensed enterprise | Buy with licence | Licence | Out of scope |
| Other buyer, highly toxic | Public-security purchase licence | Licence | No licence |
| Other buyer, precursor | Lawful-use statement | Statement | Vague |
| Individual | Prohibited (exceptions) | — | Sold to individual |
| Seller | Verify/sell by quantity | Record | No verification |
| Internet | Prohibited | — | Online order |
| Filing | Within 3 days | Receipt | Not filed |
Purchase formalities follow Articles 58, 60, 61 and 63 of the Hazardous Chemicals Safety Law; public-security and authority requirements control.
What should the contract and order contain?
At minimum: chemical name/alias/CAS, concentration/specification, quantity, use, packaging/container, batch/production date/shelf life, SDS/label version, quality standard/test method, transport method/carrier qualification, delivery location/receiving conditions, emergency contact, return/leak handling and a compliance statement (supplier warrants valid licences and a lawful upstream). For highly toxic/explosive precursors, add the purchase licence/use statement number and filing cooperation. The page may provide the field list without publishing supplier prices or customer formulas.
Acceptance checks: name/CAS; concentration; quantity; use; packaging; batch; SDS; transport; emergency; compliance statement; special clauses. Common gaps: trade name only; unknown concentration; no use; wrong packaging; outdated SDS; no carrier qualification; no compliance statement.
| Field | What to confirm | Evidence | Common gap |
|---|---|---|---|
| Name/CAS | Matches catalogue | Contract/catalogue | Trade name |
| Concentration/spec | Mixture components | SDS/COA | Unknown |
| Quantity/use | Reasonable/licensed | Order/statement | Over-quantity |
| Packaging | Compliant | Packaging proof | Non-compliant |
| SDS/label | Version/items | Documents | Outdated |
| Transport | DG qualification | Carrier documents | Ordinary truck |
| Emergency | Contact/measures | SDS/plan | None |
| Compliance statement | Licence/upstream lawful | Statement | None |
Contract fields are editorial; the purchase contract, SDS and legal requirements control.
How should SDS and labels be accepted?
Producers and traders must provide an SDS meeting laws, regulations and national/industry standards when selling, may not trade hazardous chemicals without an SDS or safety label, and may not alter the SDS or label without authorisation (Article 57); buyers may request the SDS and learn about hazards, protection and use. Check at least: composition/concentration, hazard classification, first aid, firefighting, leak handling, storage/transport, personal protection, stability/reactivity, toxicology/ecology, regulatory information and revision date. Check the label: name, hazard pictograms/signal words, hazard statements, precautionary statements and supplier information. SDS/label must match the batch, language and version.
Acceptance checks: completeness; version/date; composition; classification; first aid; firefighting; leak; storage/transport; protection; label; language; batch consistency. Common gaps: missing pages; outdated version; excessive confidentiality; label without pictograms; inconsistent languages; batch mismatch.
| Item | What to confirm | Evidence | Common gap |
|---|---|---|---|
| SDS completeness | All sections | SDS | Missing pages |
| Version/date | Current | Revision record | Outdated |
| Composition/class | Matches catalogue | SDS/catalogue | Mismatch |
| First aid/fire | Actionable | SDS | Generic |
| Leak/storage | Measures/conditions | SDS | Missing |
| Label | Pictograms/warnings | Sample | No marking |
| Language/batch | Consistent | Physical item | Mismatch |
SDS/label requirements follow Article 57 of the Hazardous Chemicals Safety Law and current national/industry standards; the standard text controls.
How should storage and in/out records be accepted?
Hazardous chemicals should be stored in dedicated warehouses, yards, rooms or cabinets managed by a dedicated person; highly toxic chemicals and other chemicals constituting major hazard installations should be stored separately in dedicated locations under dual receipt and dual custody, with receipt records kept at least 3 years (Article 41); storage units should establish in/out verification and registration; units storing highly toxic chemicals must also file the quantity, location and managers with public security (Article 42). Storage methods and quantities must meet national standards or rules. The page should state who may enter, who receives/issues, how to record, what to do on over-quantity and how to report abnormalities.
Acceptance checks: dedicated location; dedicated person; dual receipt/custody; in/out register; 3-year records; filing; storage conditions; over-quantity; monitoring. Common gaps: mixed storage; no cabinet; one person handles; lost records; no filing; over-quantity; no monitoring.
| Item | What to confirm | Evidence | Common gap |
|---|---|---|---|
| Dedicated location | Warehouse/yard/cabinet | Site | Mixed storage |
| Dedicated person | Role/training | Record | No owner |
| Dual receipt | Highly toxic/major hazard | Signatures | One person |

| Record period | At least 3 years | Ledger | Lost |
| Filing | Quantity/location/managers | Receipt | Not filed |
| Storage conditions | Standard/quantity | Site | Over-quantity |
Storage requirements follow Articles 41 and 42 of the Hazardous Chemicals Safety Law; national standards and authority requirements control.
How should transport and carriers be accepted?
Road/water transport of hazardous chemicals managed as dangerous goods must follow the law, regulations and transport authority rules (Article 64); operators must obtain a dangerous-goods road transport licence or the corresponding water licence/filing, the shipper must engage a licensed/filed carrier and may not engage other entities or individuals, and vehicles may not operate under a nominal-affiliation arrangement (Article 65); drivers, loading/unloading staff and escorts must pass assessment and hold qualifications (Article 66); for road transport of highly toxic chemicals, the shipper must apply to the county-level public security bureau at the origin or destination for a highly toxic chemicals road transport pass (Article 71). The page should state who carries, which licence, which vehicle, which people and which route.
Acceptance checks: carrier licence; vehicle operating certificate; personnel qualification; highly toxic pass; route/time; loading; emergency. Common gaps: ordinary truck;nominal affiliation; no escort; no pass; route deviation; no loading supervision.
| Item | What to confirm | Evidence | Common gap |
|---|---|---|---|
| Carrier | DG transport licence/filing | Certificate | Ordinary logistics |
| Vehicle | Operating certificate/fit | Certificate | Nominal affiliation |
| Personnel | Driver/escort qualification | Certificate | Unqualified |
| Highly toxic pass | Public security issued | Pass | None |
| Route/time | As licensed | Route sheet | Deviation |
| Loading | On-site supervision | Record | None |
| Emergency | Equipment/contact | Plan | None |
Transport requirements follow Articles 64–66 and 71 of the Hazardous Chemicals Safety Law; transport/public-security rules control.
How should records, filing and registration be accepted?
Sales of highly toxic/explosive-precursor chemicals require verification of the buyer's licence/statement and truthful records of the buyer's name, address, handler's name/ID number, chemical, quantity and use; sales records and copies of supporting documents must be kept at least 3 years; the seller and buyer must file the chemical, quantity and flow with the county-level public security bureau within 3 days and enter it into the system (Articles 60 and 61). Users may not lend/transfer highly toxic or explosive-precursor chemicals; a transfer for production changes, shutdown, relocation or closure may only be made to an entity with the corresponding licence/statement and must be filed within 3 days (Article 62). Producers and importers must register hazardous chemicals (Articles 85 and 86); major hazard installations must be registered, assessed, monitored and filed (Article 13). The page should state what to record, how long, to whom and within how many days.
Acceptance checks: sales record; 3 years; purchase record; 3-day filing; transfer filing; registration; major hazard filing; system entry. Common gaps: missing ID number; 1-year retention; 5-day filing (old rule); transfer not filed; no registration; major hazard not filed.
| Item | What to confirm | Evidence | Common gap |
|---|---|---|---|
| Sales record | Entity/handler/chemical/quantity/use | Ledger | Missing fields |
| Retention | At least 3 years | Ledger | 1 year |
| Purchase filing | Within 3 days | Receipt | 5 days/not filed |
| Transfer | Licensed entities only | Agreement/filing | Free transfer |
| Hazchem registration | Producer/importer | Certificate | Missing |
| Major hazard | Register/assess/file | Filing | Not filed |
| System entry | Public-security system | Receipt | Not entered |
Records/filing follow Articles 13, 60–62 and 85–86 of the Hazardous Chemicals Safety Law; public-security/emergency-management requirements control.
How should the hazardous-chemicals procurement and qualification page be written?
Suggested content: (1) scope (chemicals/suppliers); (2) catalogue and identification (including the 2026 adjustment); (3) supplier qualification list; (4) purchase licence/use statement; (5) contract/order fields; (6) SDS/label; (7) storage/dual receipt; (8) transport/carrier; (9) records/filing/registration; (10) emergency and exceptions; (11) contact/version/update date. The public page explains rules and entry points; it should not publish customer formulas, supplier prices, specific stock locations or security details; after login, suppliers can see their qualification/order status. State "the Hazardous Chemicals Safety Law, catalogue and authority requirements control"; do not write "a business licence is enough/all hazardous chemicals can be bought online".
Use consistent English terms (hazardous chemicals, catalogue, operating licence, purchase licence, precursor chemicals for explosives, SDS, label, dedicated storage, dual receipt/custody, dangerous-goods transport licence, filing) and state the review date. Link to supplier onboarding, SDS, transport and safety pages, but do not turn procurement into a product-safety page.
| Section | What to write | Evidence | Avoid |
|---|---|---|---|
| Scope | Chemicals/suppliers | Catalogue | Vague |
| Identification | Catalogue/2026/SDS | Announcement/SDS | Name only |
| Qualifications | Production/business/use/transport | Licences | Business licence only |
| Purchase | Licence/use statement | Documents | Contract only |
| Contract fields | CAS/concentration/use/transport | Contract | Trade name |
| SDS/label | Version/items | Documents | Outdated |
| Storage/transport | Dedicated/dual/DG | Site/documents | Mixed/ordinary truck |
| Records/emergency | 3 years/3 days/plan | Ledger | Old rules |
This structure is editorial; external statements must be truthful and verifiable, per the law, catalogue and authority requirements.
What must not be written?
High-risk claims: "a business licence is enough to supply" (production/business licences are also needed); "a business licence covers everything" (check scope/chemicals); "a contract is enough to buy highly toxic chemicals" (a purchase licence/use statement is needed); "highly toxic/explosive precursors can be bought online" (Article 63 prohibits it); "records are kept 1 year and filed in 5 days" (the new law requires 3 years and 3 days); "an ordinary truck can carry it" (a DG transport licence is needed); "store it anywhere" (dedicated location/dual receipt); "publish stock locations/security details" (sensitive). These are inaccurate or misstate qualifications, formalities or deadlines.
Safer wording: "This page applies to [chemicals/suppliers]; catalogue/2026 adjustment [checked]; supplier qualifications [production/business/use/transport]; purchase formalities [licence/use statement]; contract fields [CAS/concentration/use/transport]; SDS/label [version]; storage [dedicated/dual]; transport [DG qualification]; records [3 years/3 days]; emergency [contact/plan]. The Hazardous Chemicals Safety Law, catalogue and authority requirements control." External promotion must comply with advertising and fair-competition rules; supplier and stock information needs authorisation or redaction.
Go-live acceptance checklist
Ten checks: catalogue identification, supplier qualifications, purchase formalities, contract fields, SDS/label, storage/dual receipt, transport/carrier, records/filing, registration/major hazard, page wording and version. Each needs an owner, evidence and review date. The pass condition is not "the page says documents are complete", but that procurement, EHS, warehouse and legal can check the catalogue, verify licences, complete formalities, store correctly, transport correctly and record fully from the page.
Before go-live, run one real (anonymised) category through: catalogue → supplier qualification → purchase formality → contract → receipt → storage → issue → records → filing. Any step that fails is a gap in the page or the process.
| Check | Pass condition | Evidence | If it fails |
|---|---|---|---|
| Catalogue | Name/CAS/adjustment | Catalogue/announcement | Re-check |
| Supplier qualification | Licence/scope/validity | Documents | Stop supply |
| Purchase formalities | Licence/use statement | Documents | Apply |
| Contract fields | CAS/concentration/use | Contract | Add clauses |
| SDS/label | Complete/current | Documents | Request |
| Storage | Dedicated/dual/ledger | Site/ledger | Rectify |
| Transport | DG licence/pass | Documents | Change carrier |
| Records/filing | 3 years/3 days | Ledger/receipt | Record/file |
| Registration/major hazard | Registration/filing | Certificate/receipt | Apply |
| Wording/version | No "business licence only" | Page | Rewrite |

Who should read this, who should not, and what decisions does it support?
It suits procurement, EHS, warehouse, quality, legal and website teams at equipment, electronics/electrical, automotive, medical device, hardware, electroplating, coating, chemical, packaging and export manufacturers in Changzhou and nearby areas; also companies building a hazardous-chemicals procurement page for the first time, or facing "expired supplier licence / incomplete purchase formalities / records inspection". It does not suit teams that do not buy or store hazardous chemicals, or those wanting one page to replace legal/EHS advice.
Read it if you are building a hazardous-chemicals procurement page; only business licences are collected; licences are expired or out of scope; highly toxic/explosive precursors are bought without formalities; SDS is incomplete; storage lacks dual receipt; an ordinary truck is used; records follow old rules. Skip it if you treat "licensed" as universal, a contract as a purchase licence, ordinary logistics as DG transport, or want to publish stock/security details. It supports self-review of catalogue, qualifications, purchase formalities, contracts, SDS, storage, transport, records, registration and page wording.
FAQ
Which chemicals are hazardous chemicals, and how do we check?
Start with the Catalogue of Hazardous Chemicals (2015 edition) and later adjustment announcements; Announcement No. 3 of 2026 added five chemicals including 3-chloropropyne. The catalogue is determined, published and adjusted by the State Council emergency management department with other departments (Article 3). Then check the SDS composition/classification and label; mixtures, concentration and use can change the conclusion; assess where necessary.
Which certificates should the supplier provide?
For producers: safety production licence, business licence, hazardous-chemicals registration (producers/importers), SDS/label. For traders: hazardous-chemicals business licence and business licence. For chemical users subject to licensing: safe-use licence. For carriers: dangerous-goods road transport licence/filing. Check scope, chemicals and validity, not just a photocopy; a business enterprise may not buy from an unlicensed producer/trader (Article 53).
What is required to buy highly toxic or explosive-precursor chemicals?
Enterprises holding a safety production, safe-use or business licence may buy with that licence; other entities buying highly toxic chemicals need a public-security purchase licence; those buying explosive precursors need their own lawful-use statement; individuals may not buy them (with limited exceptions) (Article 58). Internet sale/purchase of highly toxic and explosive-precursor chemicals is prohibited (Article 63).
Can a business licence replace a production licence?
No. Production, business, use and transport are different licences/filings with different scopes. A producer needs a safety production licence (where applicable), a trader a business licence, a user possibly a safe-use licence, and a carrier a DG transport licence. Check the supplier's actual role, licence scope and validity; one certificate does not cover everything.
What should we check in the SDS and label?
Sellers must provide an SDS meeting laws, regulations and national/industry standards and may not trade hazardous chemicals without an SDS or safety label (Article 57). Check composition/concentration, hazard classification, first aid, firefighting, leak handling, storage/transport, protection, regulatory information and revision date; check the label's name, pictograms/signal words, hazard/precautionary statements and supplier information, and match the batch and language.
What changed under the 2026 law?
The Hazardous Chemicals Safety Law has been in force since 2026-05-01. Procurement-relevant points include: business licensing and the ban on buying from unlicensed enterprises (Article 53), purchase formalities for highly toxic/explosive precursors (Article 58), sales records kept at least 3 years and filing within 3 days (Article 61; the old rules were 1 year/5 days), the internet trading ban (Article 63), and dual receipt/custody with 3-year records (Article 41). The law and supporting rules control.
One-sentence takeaway
A Changzhou manufacturer's hazardous-chemicals procurement and supplier-qualification page is not about "documents complete". It should turn catalogue identification, supplier licences, purchase formalities, contract fields, SDS/labels, storage/dual receipt, transport/carrier, records/filing, registration and emergency into a reviewable checklist—so procurement, EHS, warehouse and legal can check accurately, buy lawfully, store correctly, transport correctly and record fully.
Method and limitations
This is a review of public rules and page practice, not legal, EHS or procurement advice. No undisclosed customer, formula, price or supplier data were used; processes, fields, tables and acceptance items are editorial, not legal conclusions. Catalogue and identification follow Article 3 of the Hazardous Chemicals Safety Law, the Catalogue of Hazardous Chemicals (2015 edition) and Announcement No. 3 of 2026; business/purchase/sales/storage/transport/registration follow Articles 41, 42, 48, 53–55, 57, 58, 60–63, 64–66, 71 and 85–86; the law, catalogue, supporting rules and authority requirements control. This article does not classify any specific chemical; companies should check each name/CAS/concentration/SDS.
