What qualifications do chemical suppliers need?

The qualifications required for chemical suppliers need to be distinguished based on the type of business (manufacturer/trader) and the nature of the chemicals (whether they belong to hazardous chemicals). The core essential qualifications include business license, hazardous chemical related permits, quality management certification, and testing reports. Specifically, as follows:

Quality Management System Certification
Must have GB/T19001 or ISO9001 certification, and the certification scope must cover the supplied products.
Third party quality inspection report

2、 Special requirements for hazardous chemical suppliers
If hazardous chemicals are involved, the following additional qualifications must be provided:
Dangerous Chemicals Business License
Engaging in the sale of hazardous chemicals requires obtaining and verifying the validity period and scope of the license.
Safety Production License (Manufacturer Exclusive)

3、 Supplier type segmentation requirements
(1) Manufacturer

(2) Agents/Traders
Dangerous chemical agents are required to provide a manufacturer's authorization letter.
Traders need to promise to operate legally and submit manufacturer qualification certificates.
4、 Risk Warning
Be wary of the low price trap: raw materials that are 15% below market price have a defect rate of over 70%.
Key terms of the contract: Quality acceptance standards, breach of contract liability (recommended triple penalty), and transportation safety responsibility should be clearly defined.
Note: Qualification requirements may be adjusted due to regional regulations, and it is recommended to regularly review the validity of supplier certificates.
