Every product we list links to a manufacturer lab report, and every one of those reports is only useful if you can read it. That sounds like a chore, but most of the work is pattern-matching: find a few specific lines, check they agree with the package, and confirm nothing important is missing. This guide does it the way you would at your kitchen table, with a Kraken pouch or a Club 13 bottle in one hand and the report open in the other. It also covers something many COA guides skip: a report for a liquid extract reads differently from one for plain leaf powder.
What a Kratom COA Is For
COA stands for certificate of analysis. It is a document from a testing laboratory stating what that lab found when it analyzed a sample from a particular production lot. A good one answers three questions:
- Is this what it says it is? Identity and alkaloid content.
- Is anything there that shouldn’t be? Heavy metals and microbial contaminants.
- Which product run does this apply to? A lot or batch identifier that you can match to a package.
It is not a guarantee about future lots, and it says nothing about what a product does. It is a snapshot of a sample’s composition, nothing more.
Where to Find the Report on Our Site
We don’t manufacture kratom; we carry it from brands such as Kraken and Club 13. On each product page you will find the most recent complete manufacturer report we hold for that item. One honest caveat: that report may cover a different production lot from the package that arrives at your door. So the first habit is simple — look at the lot code printed on your package and compare it with the one on the report. Our quality page explains the checks a brand must clear before we list it.
Step One: The Header Block
Start at the top of the page, before any numbers. You are looking for:
- The laboratory’s name and contact details, ideally with an accreditation reference.
- The client, meaning the brand that submitted the sample.
- A sample description naming the product, such as a specific powder or a 13 ml liquid extract.
- A lot or batch number.
- Dates for when the sample was received and when results were reported.
If the sample description says “powder” but you are holding a liquid shot, you are looking at the wrong document. That mismatch is more common than you would expect when brands reuse reports across a product family.
Step Two: The Alkaloid Results, and Why Units Change
This is where leaf and extract reports part ways.
On a leaf powder or capsule report: Alkaloids such as mitragynine are usually reported as a percentage of the sample’s weight. Some reports also list related alkaloids, including 7-hydroxymitragynine. You won’t find a percentage printed on the pouch itself, since a leaf label states weight, so the report is the only place this information lives.
On a liquid extract or shot report: Results are often given as a concentration, such as milligrams per milliliter, or as a total per container. Your job is to check whether that figure supports the label. If a Club 13 Full Spectrum Extract is labeled 150 mg MIT per 13 ml bottle, the reported concentration multiplied by 13 ml should land close to 150 mg. You don’t need it to match to the decimal; labs report within a margin, but the figure should be in the same neighborhood.
The same logic applies to drinks. A 12 oz seltzer labeled 35 mg MIT per can should have a report that, once the units are converted, supports roughly that total.
Step Three: Contaminant Panels
Kratom is a farmed plant, so a complete report screens for things the leaf could pick up from soil, water or handling.
Heavy metals. Look for four entries: lead, arsenic, cadmium and mercury. Each should show a result, the limit it was judged against, and a pass or fail status. “ND” means not detected at the lab’s reporting threshold.
Microbiology. Expect screens for organisms such as Salmonella and E. coli, plus counts for yeast and mold and total aerobic bacteria. Again, each line should carry a limit and a result.
For extracts, the base liquid and added ingredients are part of the finished product, so a report on the finished shot or can is more informative than one on the raw leaf it was made from.
Step Four: Match It to the Package
Lay the report and package side by side and confirm:
- The product name and format match.
- The lot or batch number matches the code printed on the package.
- The alkaloid figure supports the label claim, after converting units.
- Every contaminant line shows a pass.
If the lot code differs, the report still tells you something about the brand’s testing habits, but it is not evidence about your specific package. You can ask us through our contact page or request the matching report from the manufacturer.
Six Red Flags
- No lab name, or a lab that cannot be identified.
- No lot number, or one that cannot be matched to anything.
- A sample description that doesn’t match the product type.
- Missing heavy-metal or microbial sections.
- Results with no stated limits, so “pass” can’t be checked.
- A single old report used for every product a brand sells.
A “lab tested” badge with nothing behind it is not a report. Neither is a cropped screenshot that hides the header.
Why This Matters Beyond Curiosity
Several states regulate kratom under consumer-protection laws that include labeling and testing expectations, and rules keep changing. Our where we ship page lists the states and localities we can’t serve. For label basics that pair with this guide, see how to read kratom labels, and for comparing liquid products, browse the extracts collection.
Frequently Asked Questions
Why is the alkaloid figure a percentage on some reports and mg/ml on others?
Leaf is usually reported as a percentage of weight; liquid extracts are often reported as a concentration or total per container. Convert to the label’s unit before comparing.
Does a passing kratom COA mean every future lot will pass?
No. A report covers the sample from one lot. That is why the lot code matters and why a brand’s habit of testing each run counts for more than any single document.
What does “ND” mean on a lab report?
It stands for “not detected,” meaning the lab found nothing above its reporting threshold for that item.
The report on the product page has a different lot number than my package. Is that a problem?
It means the report is for a different production run. It isn’t evidence about your package, so ask for the matching report.
Do drinks and seltzers have COAs too?
They should. Club 13 lab-tests its kratom and kava products, and we post the latest manufacturer report we have on each product page.
