The Complete Guide to COA, MSDS, and Third-Party Testing for Botanical Extracts

June 2026 · 9 min read

Documentation is the foundation of trust in botanical extract sourcing. Understanding the difference between a COA, an MSDS, and a third-party test report — and knowing when you need each — will help you make smarter procurement decisions.

Certificate of Analysis (COA)

A COA is a document issued by the manufacturer or supplier that confirms that a specific batch of product meets its published specifications. For botanical extracts, a complete COA typically includes:

  • Assay results: HPLC or UV measurement of the active constituent(s), compared to the agreed specification range
  • Physical parameters: Appearance, color, odor, particle size
  • Chemical parameters: Moisture content, ash, heavy metals (Pb, As, Cd, Hg)
  • Microbiological results: Total plate count, yeast & mold, E. coli, Salmonella
  • Batch number and manufacturing date: Essential for traceability

Always request the COA for your specific shipment, not just a sample COA. Batch-to-batch variation is normal in natural products — the COA for your actual order is what matters for compliance.

Material Safety Data Sheet (MSDS)

The MSDS (also called SDS — Safety Data Sheet) is a standardized document describing the hazardous properties, handling requirements, first aid measures, and storage conditions of a chemical substance. While most botanical extracts are non-hazardous, an MSDS is still required for:

  • Customs clearance in most countries
  • Shipping documentation (especially air freight)
  • Workplace safety compliance in manufacturing facilities

Ensure your supplier provides an English-language MSDS that complies with the Globally Harmonized System (GHS) format.

Third-Party Testing (SGS, Eurofins, Intertek)

Third-party test reports add an independent layer of verification beyond the supplier's internal COA. They are particularly valuable for:

  • EU market entry (REACH compliance, novel food applications)
  • US FDA compliance for dietary supplements
  • Cosmetic ingredient documentation in the EU (CIR review support)
  • Resolving disputes about batch quality

Third-party testing typically adds 5-10 business days to your lead time and costs $200-800 depending on the test panel. Common panels include:

  • Full heavy metal panel: Pb, As, Cd, Hg, plus uranium and thallium for EU compliance
  • Pesticide screen: 500+ pesticide residues for organic/natural claims
  • Microbiological full panel: Total plate count, salmonella, E. coli, listeria, staphylococcus
  • Solvent residue: For products extracted with organic solvents (ethanol, methanol, etc.)
