Technical Documents for Every Blissam Grade
Technical data sheets, safety data sheets, batch certificates of analysis and the ISO 9001 certificate. Issued on request so that you always get the current revision — not a PDF that was uploaded two years ago.
Five Documents We Issue

Per grade. Carries the same release specification published on the product page, plus handling and storage guidance.
Safety Data Sheet (SDS)
Per grade, in the format required for import and workplace compliance.
Certificate of Analysis (COA)
Per batch. Actual tested values against the release specification.
Certificate of Origin and export set
Commercial invoice, packing list and certificate of origin.
ISO 9001 certificate

Documentation Questions
Why are the documents not posted as PDF downloads?
Because a stale PDF on a website is worse than no PDF. TDS and SDS revisions change, and a COA is specific to the batch you receive. Requesting them means you get the current revision for the grade you are actually buying, and the SDS in the format your country requires.
How quickly are documents sent?
Normally the same working day for catalogue grades during Hangzhou office hours (Mon–Fri 08:30–18:00, GMT+8). WhatsApp messages sent outside those hours are answered when the office opens.
Can you send documents for several grades at once?
Yes — list the grade codes in one message and the whole set is issued together.
Do you supply documents for supplier qualification?
Yes. Tell us what your qualification file needs — ISO 9001 certificate, quality manual summary, product specifications, SDS set — and we will assemble it.
Where do I find the specification before I request anything?
On the product page itself. Every one of the 91 catalogue grades publishes its full technical index on this site, so you can screen grades before contacting anyone.
Send Us Your Grade List
One message with the grade codes and the destination country is enough. The document set comes back together, in the revision that matches what you will actually receive.
