Kratom Certificate of Analysis

A kratom certificate of analysis (COA) is a laboratory report for one specific batch of kratom powder. It lists what the lab tested, which methods it used, when it ran them and what it found. A COA is only useful if the batch number on the report matches the batch number on your package. This guide shows you how to check that, what each section means and which red flags to look for before you rely on a report.

We sell kratom powder for soap making and related accessories, and we publish a lab report for every batch. The checks below are the ones we apply to our own documents.

TL;DR

• A COA describes one lot or batch. A generic PDF for a whole product line does not prove that the package in your hands was tested.
• Match the batch number, check the lab name, the test dates and the methods, and confirm the panel covers alkaloids, heavy metals, microbes and, where relevant, mycotoxins and pesticides.
• ISO/IEC 17025 accreditation shows a laboratory is technically competent for defined methods. It is not a seal on the product.
• Requirements differ by jurisdiction. A report that satisfies one state’s rules may not satisfy another’s.
• Our batch reports are public on our lab reports page, and each is traceable by batch number.

What a certificate of analysis is

A COA is a formal document issued by a laboratory. It ties a physical sample to a set of analytical results through an identifier, usually a lot or batch number. According to the Utah Department of Agriculture and Food, a registration COA must carry a lot number that matches the product, the dates the sample was received and the testing completed, the methods of analysis, the processor and laboratory details, and a photo of the product. Utah’s list is a useful model of what a complete report contains, even if you are nowhere near Utah.

A COA describes composition. It does not make claims about benefits, and it does not approve a botanical for any particular purpose. Laboratory-testing specialists make the same point: independent testing is valuable because it reduces conflicts of interest and supports batch-level verification, but it does not turn a plant material into an approved product.

That is also why the document matters in a practical way. For a manufacturer, a soap maker or a reseller, the COA is the record that lets you compare one batch with the next and decide whether a lot suits your process.

What you should find on a kratom COA

Reports differ in layout, but a thorough one contains the same building blocks.

Published laboratory methods give you a vocabulary for this. A kratom testing lab such as ACS Laboratory describes chromatographic methods for alkaloids, ICP-MS for metals, and microbiological testing for organisms including Salmonella, E. coli, yeast and mold. The exact panel varies by laboratory and jurisdiction, so compare the list of analytes and methods on the report, not just the presence of a “lab tested” badge.

How to read a COA step by step

1. Find the batch number on your package. It is usually printed on the label or the back of the bag. Write it down before you open the report.
2. Open the report and compare the batch number character by character. A report with a different number, or no number, cannot establish that your batch was tested.
3. Check the laboratory. Look for a named lab with an address and contact details. A report that only carries the seller’s logo is a red flag.
4. Read the dates. The sample should have been received and tested before the product was sold, and the report should not be years old. Utah, for example, requires that registration testing be completed within the 6 months before registration.
5. Review the alkaloid section. Confirm that values are reported with units and a method, and note the figures so you can compare batches.
6. Review the contaminant sections. Heavy metals, microbiology, mycotoxins and pesticides should each be present or clearly marked as not tested.
7. Look at reporting limits and acceptance limits. A result of “ND” (not detected) only means something when you know the lowest level the method can detect.
8. Check how the document reached you. A QR code or an online portal that opens the same report from the lab’s own system is stronger than a PDF attached to a product page.

If you want a deeper walk through the numbers, our guide on how to read a kratom COA goes through the six figures that matter most.

Batch-specific versus generic reports

The most common mistake is accepting one undated PDF as proof for an entire product range. A meaningful COA identifies the tested material, the dates, the laboratory, the methods, the results and the acceptance limits. A product-line page with no matching lot number cannot show that the package in hand was tested, and the Sparta Labs guide to COAs makes the same distinction between a batch record and a general statement.

Batch specificity matters because plant material varies from harvest to harvest. Two lots of the same strain can show different alkaloid values, moisture and particle size. For soap makers this affects color, scent and how a measured amount behaves in a recipe. We explain this in more detail in our article on kratom batch variability for soap, which recommends checking the batch COA first.

Accreditation: what ISO/IEC 17025 does and does not mean

Many reports mention ISO/IEC 17025. It is the international standard for the competence of testing and calibration laboratories. When a lab is accredited, an independent accreditation body has assessed that it is technically capable of performing specific tests. Three points are worth remembering:

• It certifies the lab, not the product. Accreditation does not approve the material that was tested or guarantee suitability for any use.
• It applies to a defined scope. A laboratory may be accredited for one technique or analyte while another test on the same report falls outside its accredited scope. Ask for the scope document or check the accreditation body’s directory.
• It is not universal. Utah requires a third-party laboratory accredited to ISO/IEC 17025:2017 for registration COAs, but other jurisdictions word their requirements differently.

Some specialist labs state their accreditation scope openly. Murray Brown Labs, for instance, describes itself as ISO/IEC 17025:2017 accredited for analyzing kratom alkaloids, including mitragynine. That is the kind of specific statement to look for, rather than a vague claim of being “certified.”

Why contaminant panels deserve their own look

Alkaloid values tell you about plant chemistry. They say nothing about whether a lot is free of microbial or heavy metal contamination. A strong potency figure cannot substitute for a clean microbiology section.

Public records show why the microbial panel is a separate decision point. The FDA has published a company announcement of a kratom powder recall for possible Salmonella contamination. The recall has been completed and terminated, but it illustrates that identity and alkaloid content alone cannot rule out microbial findings. When you review a report, read each line of the microbiology section on its own.

The practical review list is short:

• Alkaloid identity and concentration
• Heavy metals
• Microbial organisms, including Salmonella and E. coli
• Mycotoxins
• Pesticides, where applicable to plant matter
• The analytical methods and reporting limits behind each result

Tested versus untested: what changes for a buyer

The difference between a tested and an untested batch is not a quality label. It is documentation. With an untested product you have the seller’s description and nothing to verify. With a tested product you have a document you can check against the package, the laboratory and the dates.

A tested batch is only as good as the report that comes with it, so apply the same questions every time:

• Does the batch number match?
• Is the lab independent of the seller?
• Are all the relevant panels present?
• Are the methods and limits stated?
• Can you open the same report from the lab or from a link that stays live?

A “yes” to all five is what we mean by a lab-tested product. For a wider look at how we think about this, see our overview of kratom lab testing.

Rules differ by jurisdiction

There is no single worldwide license for selling kratom. Requirements depend on the jurisdiction, the product classification and the business activity. Two US examples show how far the details can differ:

• Utah requires product registration supported by labeling and a qualifying COA. It prescribes the analytes (mitragynine, 7-hydroxymitragynine, pseudoindoxyl, foreign matter, microbial standards, heavy metals, mycotoxins and, for plant matter, pesticides), the lab credentials and the recency of testing. Its testing requirements page is the primary source.
• Texas enacted legislation in 2025 requiring covered products to be tested by an appropriately accredited laboratory before sale. Senate Bill 1868 also states that selling an untested or improperly labeled product is an offense and that intentionally falsifying a required laboratory report is a third-degree felony.

The lesson for any reseller or retailer is that a complete COA is jurisdiction-specific. A report adequate for one market may not satisfy another. Before you sell, verify the current law in the state or country where you operate, and ask a qualified attorney or your regulator if the classification of your product is unclear. Our readers in Europe and the UK should do the same with their national rules, since the examples above are US state laws and do not apply elsewhere.

What it costs to obtain a COA

If you are a producer or reseller who wants your own batch tested, published laboratory prices give a reference point. Murray Brown Labs lists a $300 cost, a 60 g sample requirement for powder, 3 g for extracts and a 5-business-day turnaround. Its volume pricing for 11 or more samples lists potency at $95 per sample and metals at $80 per sample.

These are one laboratory’s published figures, not an industry rate. A full panel, rush service, sample type, location and the analytes you request can all change the quote. Request a written quote that lists every analyte and method before you send a sample.

To obtain a COA, the usual path is:

1. Choose an accredited laboratory whose scope covers the tests you need.
2. Collect a representative sample from the finished batch and label it with the batch number.
3. Submit the sample with the panel you want.
4. Receive the report and check that the batch number, dates and methods are correct before you publish it.

Some laboratories offer online portals, such as the Cambium Analytica platform, where you can order tests and track samples. Portals like this make it easier to keep reports organized by batch.

Our perspective

We built Kratomvia around a simple idea: a buyer should be able to verify what they hold. That is why we source from a small, known network of growers rather than anonymous bulk suppliers, send every batch for independent laboratory testing and keep each batch traceable by number.

We make the lab results public on our lab reports page because a report that sits behind a request form is hard to check. Our rule is the same one we recommend above: the report must match the batch. We would rather a customer compare the number on the bag with the number on the document than take our word for it.

We also see how the report is used in practice. Our powders are sold for soap making and related crafts, and batch records help makers keep results consistent from one production run to the next. A maker who writes down the batch number with each recipe can trace any difference in color or texture back to a specific lot.

A COA is not a marketing asset. It is a working document, and the useful ones are specific, dated and easy to verify.

FAQ

How do I get a certificate of analysis?

A producer or reseller sends a representative sample of a batch to a laboratory, which tests it and issues the report. Choose a lab accredited for the methods you need, and confirm the batch number, dates and methods on the finished document. If you are a buyer, ask the seller for the report that matches the batch number on your package.

How much does a certificate of analysis cost?

It depends on the laboratory and the panel. One published kratom lab lists $300 per sample, with a 60 g powder requirement, and lower per-test pricing for volume orders. Ask for a written quote that lists every analyte before you commit.

What kind of license do you need to sell kratom?

There is no single worldwide license. Rules depend on the country or state, how the product is classified and what your business does. Utah ties sales to product registration with a qualifying COA, and Texas requires pre-sale testing by an accredited laboratory. Check current local rules with your regulator or an attorney before you sell.

Does a COA from an accredited lab guarantee the product is suitable for any use?

No. ISO/IEC 17025 shows a laboratory is competent for specific methods, and the COA describes the composition of one tested batch. Neither approves the material for a particular purpose, so judge suitability against your own process and the rules where you operate.

Where can I see Kratomvia’s lab results?

Our batch reports are available on the kratom lab reports page. Find the batch number on your package and match it to the report.
