The Complete Guide to Chemical Documentation: CoA, SDS, TDS, and Why They Matter for International Buyers

For buyers sourcing industrial chemicals internationally understanding the

documentation package that accompanies every legitimate chemical shipment is

not merely a compliance formality — it is the primary quality assurance

mechanism that protects buyers from substandard product, customs clearance

failures, and regulatory non-compliance.

This guide explains the core documents that UAB An Group Export provides with

every order and what to look for in each one.

Certificate of Analysis (CoA)

The Certificate of Analysis is the primary quality document for any chemical product. It certifies that the specific batch of product supplied has been tested and meets specified quality parameters.

A legitimate CoA must include the product name and CAS number, batch

or lot number unique to the specific production batch, test results for key quality parameters including purity, physical characteristics, and any critical impurity limits, the name and signature of the authorised quality control analyst, and the date of analysis.

Generic or template CoAs without specific batch reference numbers

are a significant quality red flag — they indicate the supplier may not

be performing actual batch-specific quality testing.

Safety Data Sheet (SDS)

The Safety Data Sheet is a mandatory regulatory document required for all

chemical substances and mixtures. Under the GHS (Globally Harmonised

System) a compliant SDS must contain exactly 16 sections covering

identification, hazard identification, composition, first aid measures,

fire-fighting measures, accidental release, handling and storage,

exposure controls, physical and chemical properties, stability and

reactivity, toxicological information, ecological information, disposal,

transport, regulatory information, and other information.

The SDS must be in the language of the destination country for regulatory

compliance in most jurisdictions.

Technical Data Sheet (TDS)

The Technical Data Sheet provides detailed technical specifications and

application guidance beyond what appears on the product label or CoA.

It covers physical and chemical properties in detail, performance

characteristics, recommended applications, handling and storage

guidance, compatibility information, and regulatory data relevant to

professional users.

The TDS is the document procurement teams and process engineers use to

evaluate whether a chemical product meets their specific technical requirements.

Export Compliance Documentation

International chemical shipments additionally require commercial

invoice with accurate chemical description and UN number where

applicable, packing list with individual package weights and

dimensions, dangerous goods declaration for UN-classified

substances, and import permits or end-use declarations where

required by destination country regulations.
