How to Read a Moringa COA: A B2B Buyer's Guide
Every shipment should ship with a Certificate of Analysis. Here's what the numbers actually mean — and what to reject.

A Certificate of Analysis (COA) is the technical document that travels with every batch of moringa. It's how you verify what's on the label matches what's in the container. Many buyers — especially first-time importers — accept COAs at face value. Here's a practical guide to reading one.
A complete moringa powder COA contains four sections: physicochemical (appearance, moisture, ash, particle size); microbiological (total plate count, yeast & mould, E. coli, Salmonella); contaminants (heavy metals, pesticide residues, aflatoxins); and documentation (batch number, dates, lab name and accreditation). For premium-grade powder, look for moisture <6%, ash <9%, plate count <500,000 cfu/g, yeast & mould <10,000 cfu/g, E. coli and Salmonella absent. Heavy metals reported against EU 1881/2006 (lead <3.0 mg/kg, cadmium <0.2, mercury <0.1).
Warning signs to reject: a COA on company letterhead with no third-party lab name; generic 'compliant' values without specific numbers; missing parameters (especially heavy metals); test methods not cited (ISO, AOAC, USP); the lab not accredited by NABL, DAkkS, or A2LA.
A premium COA references specific methods — ISO 4833 for plate count, ICP-MS for heavy metals, AOAC for ash, USP <921> for moisture. Without method references, the numbers are unverifiable. NABL-accredited labs always cite methods — part of the ISO/IEC 17025 standard. A good COA is your defence at customs, in audits, and against product liability claims. Make it a non-negotiable: every shipment, every batch, NABL-accredited lab, methods cited.
