Use each document for the decision it supports
The specification defines acceptance criteria. The COA reports results for a particular batch. The TDS describes technical identity and use information. The SDS communicates handling and safety information. One document should not be used as a substitute for another.
A complete review also checks issue dates, revision numbers, analytical methods, units, signatures or approval status, and whether the product name and code match the sample or shipment.
Additional documents depend on risk and market
Botanical extracts may require plant species, plant part, extraction solvent, carrier and contaminant information. Defined molecules may require identity, purity and impurity controls. Market-specific declarations should be requested only when they are relevant to the intended country and finished product.
