FAQ
Document questions
What is the difference between COA, SDS and TDS?
The COA reports the tested results for one specific batch. The SDS/MSDS covers safety, handling, transport and emergency information. The TDS describes typical technical properties and recommended handling for the product in general.
Is the COA specific to the batch I receive?
The purchase agreement should require a lot-specific COA when batch release depends on tested values. Confirm that the lot identity on the document matches the material received.
Can you provide English documents for customs clearance?
State the required language, destination and document list before quotation. Availability and responsibility for each file are then confirmed in writing.
What should I check first in a DMT COA?
Purity, color, acid value, moisture, ash and the impurity profile, and confirm the test method behind each reported value.
