COA vs TDS vs MSDS: Chemical Buyer's Guide

Understanding batch test certificates, technical data sheets, and safety documentation in B2B chemical procurement.

The Three Core Quality Documents in Chemical Sourcing

Purchasing managers, plant quality control (QC) teams, and safety officers require three essential documents when onboarding new chemical suppliers:

1. Certificate of Analysis (COA)

A batch-specific document certifying actual laboratory test results for the specific lot delivered. It verifies parameters like assay purity, specific gravity, moisture content, refractive index, and impurities against agreed specifications.

2. Technical Data Sheet (TDS)

A general product reference document detailing standard physical/chemical properties, recommended dosage, typical applications, and handling instructions.

3. Material Safety Data Sheet (MSDS / SDS)

A safety compliance document mandated by law, outlining hazard identification, first-aid measures, spill handling, storage guidelines, and PPE requirements.
