What Is a COA and Why It Matters
If you’ve spent any time in kratom communities, you’ve seen the acronym COA thrown around. It stands for Certificate of Analysis, a document from an independent, third-party laboratory that verifies what’s actually in a specific batch of kratom.
A real COA isn’t a generic lab report that a vendor ran once two years ago. It’s batch-specific. That means the lab tested the exact lot of kratom that ended up in your bag, not a sample from a different harvest, a different supplier, or a different year.
What a COA Should Include
A thorough COA for kratom includes:
- Alkaloid panel, Mitragynine and 7-hydroxymitragynine percentages, at minimum. These are the primary active compounds in Mitragyna speciosa leaf.
- Contaminant screening, Tests for heavy metals, microbials (E. coli, salmonella), and mold/yeast counts.
- Batch/lot number, The specific identifier that ties the report to the product in your hands.
- Lab name and accreditation, The testing facility should be identified and ideally ISO-accredited.
- Date of testing, So you know the report is current and relevant.
How TVN Handles COAs
Every bag we ship carries a lot number. That lot number matches a batch-specific COA with a full alkaloid panel. We don’t reuse old reports. We don’t test one batch and apply the results to a different one.
Scan the QR code on your bag, enter the lot number on our Batch Verify page, and you’ll see the exact lab results for the kratom you’re holding. That’s the whole point.
Red Flags to Watch For
- Vendors who claim to test but never show the actual document
- COAs with no lot number or a generic “sample” label
- Reports that are months or years old with no connection to current inventory
- Labs you can’t verify or find online
Transparency isn’t a marketing angle for us. It’s the baseline. If a vendor can’t show you a batch-specific COA for the product they’re selling you right now, ask yourself why.
