Safety data sheet
Ask for the current SDS that matches concentration, physical form and language needed at the US destination. Handling, storage and transport follow this file, not this website.
Document guide
Fine chemicals manufacturer files to request before inquiry
This page is a buyer checklist for SDS, TDS, CoA and regulatory questions. It is not an ESG statement and it does not certify Fine Chemicals Sourcing or any factory.
Files bound to the quoted product only
Technical data sheet
Use the TDS to list assay, purity, moisture, particle size or other limits the buyer already wrote. A missing limit stays open.
Certificate of analysis
Request the CoA format and the fields that will appear on a future lot. A sample CoA from another CAS is not evidence.
Regulatory questions that remain supplier answers
- TSCA status for the quoted CAS when the destination is the United States.
- REACH status only if the buyer needs that statement for the same product.
- GMP or ISO quality-system files only when the buyer listed them and the supplier binds them to a site and date.
- DOT or IMDG transport information taken from the exact SDS and carrier rules.
Document trade-off: a recent SDS without a lot-specific CoA does not close identity. A CoA without the matching SDS does not close handling. Request both and record which file is still missing.
Approval questions before the RFQ leaves the buyer
At minimum: chemical name, CAS if known, grade, assay or concentration, package net content and whether the offer matches the requested configuration.
Laboratory acceptance, EHS review, transport booking and any alternative grade still need buyer decisions. This guide does not close those items.
