Important context: This guide is educational. Laboratory accreditation is an important evidence check, but it is not an FDA approval, a guarantee of product safety or a substitute for reviewing the actual product, lot, sample and results. FDA states that kratom is not lawfully marketed in the United States as a drug product, dietary supplement or additive in conventional food. References to food-testing and dietary-supplement quality systems below explain useful laboratory concepts; they do not change kratom’s federal regulatory status.
The short answer
Do not stop at a laboratory logo or the phrase “ISO certified.” To verify a kratom laboratory, find the accreditation certificate and its separate scope, confirm them through the accreditation body’s directory, and match the laboratory name, physical location, certificate number, status and dates. Then check whether the scope covers the type of test, method and matrix represented on the certificate of analysis, or COA.
The strongest evidence chain answers five different questions:
- Is the laboratory real, and did it issue this report?
- Is its accreditation active for the named location?
- What testing activities are actually within its accredited scope?
- Does the COA identify the exact product, lot, method and results?
- Did the named laboratory perform every reported test, or were some results produced elsewhere?
An active ISO/IEC 17025 accreditation can support confidence in a laboratory’s competence and consistent operation. It does not make every service offered by that laboratory accredited. It also does not prove that the submitted sample represents every unit in a production lot.
What ISO/IEC 17025 means
ISO/IEC 17025 is an international standard for the competence, impartiality and consistent operation of testing and calibration laboratories. The current edition is ISO/IEC 17025:2017. Accreditation bodies use the standard when assessing laboratories.
This is different from a laboratory merely saying it “follows,” “uses” or is “compliant with” ISO/IEC 17025. Accreditation is a formal third-party decision. NIST describes its accreditation process as involving an application, assessment, resolution of identified nonconformities, proficiency testing and technical evaluation, followed by issuance of a certificate and scope of accreditation.
The wording matters:
- Accredited: A recognized accreditation body has made a formal decision within a defined scope.
- Certified: This word may refer to a different type of conformity assessment and should not be treated as a synonym without documentation.
- Compliant with: A claim that needs evidence; it is not automatically a third-party accreditation.
- Accreditation pending: Not active accreditation.
- Uses ISO methods: A method reference does not establish laboratory accreditation.
For a consumer, the practical lesson is simple: the certificate identifies the laboratory’s accreditation, while the scope explains what that accreditation covers. You normally need both.
Accreditation is limited by scope
Accreditation is not a blanket approval of every analysis a laboratory can sell. A laboratory may offer services beyond its accredited scope. That is not automatically improper, but the distinction should be clear when a brand presents a result as accredited.
Depending on how an accreditation body formats its records, the scope may identify:
- fields or disciplines of testing;
- materials or matrices;
- analytes, organisms or measurands;
- methods, standards or laboratory procedures;
- measurement ranges or capabilities;
- specific laboratory locations; and
- notes, limitations or flexible-scope provisions.
A general heading such as “chemical testing” is not the end of the review. Open the complete scope and inspect the entries beneath it. If the COA reports lead, arsenic, cadmium and mercury in botanical powder, look for scope information that reasonably corresponds to elemental analysis of the relevant material using the reported method. If the COA reports Salmonella, examine whether the scope covers microbiological testing and the stated procedure for an appropriate matrix. If it reports mitragynine and 7-hydroxymitragynine, examine the chemistry scope and the laboratory method identified on the report.
Do not silently broaden a scope. A scope for drinking-water analysis does not automatically cover botanical powder. A scope for one organism does not establish competence for every microbial test. A scope for metals does not cover alkaloids. A scope for a company’s headquarters may not cover a different testing location.
When the connection is not clear, ask the laboratory or accreditation body for confirmation rather than guessing.
Certificate versus scope: why both documents matter
The accreditation certificate usually provides high-level information such as:
- the laboratory’s legal or operating name;
- accredited location;
- accreditation body;
- certificate or accreditation number;
- standard and edition;
- effective, issue or expiration dates; and
- status or conditions.
The scope usually supplies the technical boundaries. A certificate without its scope can show that a laboratory holds an accreditation while leaving unanswered whether the specific analysis is covered.
The reverse is also true. A detached scope page can become stale or can be separated from the certificate to which it belongs. Match the name, location, identifier, revision date and page numbering across both records.
A practical ten-step verification method
Step 1: Start with the full COA
Use the complete laboratory report, not a cropped result table or a seller-created summary. Look for:
- laboratory name and contact information;
- report or sample number;
- client name, when shown;
- product or sample description;
- lot or batch identifier;
- date received, date tested and report date;
- methods;
- results and units;
- signatures or authorization information; and
- accreditation marks or qualifying notes.
If the file has only a list of green “Pass” labels, it does not contain enough information for a serious review.
Step 2: Confirm the laboratory identity
Compare the laboratory name and address on the COA with the accreditation record. Watch for similar business names, parent-company names and multiple locations.
Accreditation is often location-specific. If the directory lists a Denver facility but the report came from a facility in another state, do not assume the second address is included. Find that location’s own record or ask for clarification.
Step 3: Identify the accreditation body
The logo on the report should connect to a named accreditation body. Search the accreditation body’s own directory rather than relying solely on a PDF hosted by the vendor or laboratory.
ILAC explains that accreditation bodies issue certificates with scopes and recommends contacting the accreditation body to confirm a laboratory’s status and scope. ILAC also maintains signatory information and links to directories of accredited facilities.
The useful chain is:
COA → laboratory → accreditation body → active directory record → certificate and scope
Step 4: Check status and dates
Confirm that the accreditation was active when the relevant testing occurred. Examine issue, renewal, revision, expiration, suspension and withdrawal information.
Do not rely on a certificate merely because it once existed. A current directory record is stronger evidence than an undated image copied onto a marketing page. If the testing date predates or follows the documented accreditation period, ask whether another certificate version applies.
Step 5: Open the complete scope
Read every page. Some scopes place general testing categories on the first page and the actual methods or analytes later. Confirm that all pages share the same laboratory identity and accreditation number.
Look for the combination that matters to the COA:
- test discipline;
- matrix or product category;
- analyte or organism;
- method or procedure; and
- laboratory location.
The exact structure varies. The goal is not to force every scope into the same template; it is to understand what the accreditation body actually approved.
Step 6: Match each COA section separately
A typical botanical-product COA may combine several disciplines:
| COA section | What to compare with the scope |
|---|---|
| Alkaloids | Chemical testing, relevant analytes, matrix and chromatography method |
| Heavy metals | Elemental analysis, relevant elements, matrix and ICP-MS or other stated method |
| Salmonella | Microbiological testing, organism, matrix and method |
| Aerobic count | Quantitative microbiology, matrix and method |
| Yeast and mold | Quantitative microbiology, matrix and method |
| Identity | Botanical, chemical or other identity method actually reported |
Coverage of one row does not prove coverage of the others. Review every section claimed to be accredited.
Step 7: Compare methods, not just analyte names
The COA should identify a recognized standard method, a compendial method or a laboratory-developed method clearly enough to support review. A scope may use an abbreviated method code while the report uses the laboratory’s fuller title.
Reasonable naming differences can occur. The critical question is whether the accreditation body’s approved scope covers the activity represented by the report. If the method code, revision or matrix appears different, ask the laboratory for the mapping.
Do not assume that seeing “ICP-MS” proves the method is accredited. ICP-MS describes an analytical technology. The relevant scope still needs to cover the testing activity, and the report still needs valid sample preparation, calibration, quality controls and review.
Step 8: Look for accredited and non-accredited result markings
Some laboratory reports distinguish tests within scope from tests outside scope by a symbol, footnote or statement. Read the report legend and all footer notes.
A report can contain both accredited and non-accredited work. The presence of an accreditation mark at the top should not be interpreted as universal coverage when a note limits the claim.
If the distinction is not visible, ask:
Which exact results on this report were performed within your current ISO/IEC 17025 scope at the named location?
Request a written answer tied to the report number.
Step 9: Identify subcontracted or externally provided results
One laboratory may coordinate a panel while another performs part of it. For example, the issuing laboratory might conduct alkaloid testing and send microbiology to a separate facility.
That arrangement is not automatically a flaw. The concern is transparency. Determine:
- which laboratory performed each analysis;
- whether the performing laboratory is identified;
- whether its location and accreditation are current;
- whether its scope covers the work; and
- whether the issuing report preserves the original result and method context.
Never assume that the issuing laboratory’s scope transfers to a separate performing laboratory. NIST accreditation guidance warns against presenting another laboratory’s data as if it were covered by the issuing laboratory’s accreditation.
Step 10: Verify report authenticity
Use a laboratory-hosted verification link, QR code, client portal or direct confirmation when available. Give the laboratory the report number and ask whether it issued the document and whether it has been revised or withdrawn.
Signs that deserve follow-up include:
- a report number that cannot be verified;
- inconsistent fonts or altered tables;
- missing pages;
- a product name pasted over another description;
- a lot number that does not match the package;
- dates that do not make chronological sense;
- missing method and unit information;
- an expired accreditation symbol; or
- a vendor-hosted certificate that conflicts with the accreditor’s directory.
What accreditation does not prove
ISO/IEC 17025 accreditation is evidence about laboratory competence and operation within scope. It does not, by itself, prove any of the following:
It does not prove that the product is FDA-approved
Laboratory accreditation and product authorization are different questions. FDA’s position on kratom is not changed by an ISO/IEC 17025 logo.
It does not prove the product is safe for every person
A laboratory measures defined characteristics in the submitted sample. It does not evaluate every personal circumstance, interaction, use pattern or future condition of the product.
It does not create a universal passing specification
A method can generate a technically valid result without deciding what limit a brand should use. The specification, legal basis, product category, units and reporting basis still need review.
It does not prove every package matches the sample
Testing is only as representative as the sampling plan, lot controls and chain of custody. A valid result for one sample is not automatically a result for a different lot.
It does not prove every test on the COA is accredited
Coverage is determined by the active scope and any report qualifications—not by the laboratory’s general reputation.
It does not eliminate uncertainty
All measurements have limitations. Reporting limits, method performance, matrix effects, sampling variability and measurement uncertainty still matter.
Accreditation body verification and the ILAC MRA
ILAC’s mutual recognition arrangement connects peer-evaluated accreditation bodies. Its signatory search can help identify accreditation bodies and the recognition scopes for which they are signatories. The accreditation body’s directory can then be used to locate a laboratory and its current scope.
This creates two separate checks:
- Verify the accreditation body and its relevant recognition status.
- Verify the laboratory through that accreditation body’s current directory.
Do not treat the ILAC name as if ILAC itself directly tested the product or accredited the laboratory. The laboratory is accredited by an accreditation body. The product sample is tested by the laboratory.
Likewise, the presence of a combined mark does not replace reading the scope. Marks communicate status under defined conditions; they do not expand technical coverage.
The 2026 ILAC and IAF transition
Accreditation records are also moving through an organizational transition. FDA states that the International Laboratory Accreditation Cooperation and the International Accreditation Forum merged into Global Accreditation Cooperation Incorporated, effective January 1, 2026. FDA’s current LAAF page says that, during the transition, it recognizes signatories associated with both ILAC and the new organization; after the transition, only the merged organization will be recognized for that program.
This does not mean an old laboratory logo should be accepted without review, and it does not mean every document using the ILAC name became invalid on January 1. It means reviewers may encounter legacy and successor names while systems and marks transition. Use the current FDA program page, the relevant recognition directory and the laboratory’s accreditation body to confirm status rather than deciding from the logo alone.
FDA’s LAAF program: an important but limited distinction
FDA’s Laboratory Accreditation for Analyses of Foods program, or LAAF, uses additional federal requirements for food testing in specified circumstances. FDA maintains a public registry of recognized accreditation bodies and LAAF-accredited laboratories. FDA states that only certain testing circumstances require use of a LAAF-accredited laboratory.
LAAF accreditation should not be casually described as a universal requirement for every commercial botanical-product COA. Nor should ordinary ISO/IEC 17025 accreditation be called “FDA accreditation.” These are distinct claims.
When a laboratory references LAAF, verify:
- that it appears in FDA’s registry;
- that its status is current;
- that the relevant method is within its LAAF scope; and
- that the testing circumstance is one to which the LAAF requirements apply.
FDA’s LAAF materials define scope in relation to the testing methods for which a laboratory is LAAF-accredited. They also explain that suspension, scope reduction and withdrawal can be reflected in the public registry. This reinforces a broader rule: verify current status, not just a saved certificate.
For Kiody’s educational pages, ISO/IEC 17025 and LAAF should be written as separate concepts. Neither label should be used to imply FDA approval of kratom.
How to read the laboratory section of a COA
Use this compact checklist when a report is already open:
| Question | Strong evidence | Warning sign |
|---|---|---|
| Who issued it? | Full laboratory name and location | Logo with no legal identity |
| Which report? | Unique report and sample numbers | Generic reusable sheet |
| Which product? | Exact sample description and lot | “Kratom” with no form or lot |
| When tested? | Receipt, testing and report dates | Missing or illogical dates |
| What method? | Named standard or lab method | No method information |
| What scope? | Current accreditor-hosted scope matches work | Certificate only, no scope |
| Who performed it? | Performing laboratory is identifiable | Unexplained outside results |
| Which results are accredited? | Clear symbol, legend or written confirmation | Blanket logo with ambiguous coverage |
| Can it be authenticated? | Portal, QR or direct lab confirmation | Seller image only |
One missing item is not automatic proof of fraud. It is a reason to request the missing evidence before relying on the claim.
Botanical leaf, extracts and concentrated 7-OH are different testing questions
Laboratory verification should preserve product form. A scope or method suitable for botanical powder should not be assumed to cover a concentrated extract, liquid, tablet or other formulated product.
Ordinary botanical leaf contains a complex alkaloid profile and is not the same product category as concentrated or enhanced 7-hydroxymitragynine. A contaminant panel does not determine whether a product is ordinary leaf, and an alkaloid panel does not replace contaminant testing.
For a pure-leaf capsule, review at least:
- the botanical fill material;
- capsule shell ingredients when relevant;
- product and lot identity;
- alkaloid method and results;
- heavy-metal method and results;
- microbiological method and results; and
- the accreditation scope for each claimed test.
For an extract or other concentrated product, confirm that the laboratory method and scope are suitable for that matrix and concentration. Do not reuse a leaf-powder report as if it tests a different formulation.
Kiody does not sell concentrated 7-OH. Any educational discussion of enhanced 7-OH, mitragynine pseudoindoxyl, MGM-15 or MGM-16 should remain clearly separated from Kiody’s botanical-leaf catalog and should not imply direct equivalence.
Common accreditation warning signs
“ISO certified” with no standard number
Ask whether the laboratory is accredited to ISO/IEC 17025:2017 and request the accreditation body’s directory entry.
A certificate but no scope
The certificate establishes only the high-level status. It does not show whether the requested method is covered.
A scope for a different address
Verify the actual performing location.
A seller-hosted certificate that is expired
Use the accreditor’s current directory. Request the renewed certificate if the directory shows active status.
A broad logo on a mixed report
Read symbols and footnotes to determine which results are within scope.
A method name with no matrix connection
Ask whether the specific product type was included in the laboratory’s validation, verification or scope representation.
Results copied from another laboratory
Identify the performing laboratory and its scope. Do not transfer accreditation by association.
A cropped COA
Request every page, including methods, notes, signatures and legends.
A passing result with no specification
Ask what limit was used, where it came from and whether the unit and reporting basis match the result.
A report that does not match the lot
Even excellent laboratory work cannot repair a broken product-to-sample link.
Frequently asked questions
Is an ISO/IEC 17025 laboratory automatically approved by FDA?
No. ISO/IEC 17025 accreditation and FDA product approval are different matters. FDA has specific laboratory programs, including LAAF for certain food-testing circumstances, but an ordinary ISO/IEC 17025 accreditation should not be presented as FDA approval.
Does ISO/IEC 17025 cover every test a laboratory offers?
No. Accreditation applies within the laboratory’s documented scope. A laboratory can offer testing that is not within that scope.
Where should I verify a laboratory?
Start with the accreditation body named on the report and use that body’s official directory. ILAC’s signatory information can help identify accreditation bodies and their recognition areas.
Is the certificate enough?
Not usually. Review the complete scope to see the technical activities covered.
What if the laboratory has several locations?
Match the address on the COA to the accredited location. Do not assume every branch shares the same scope.
Can one COA include both accredited and non-accredited results?
Yes. Read the report’s legend, symbols and qualifying statements. Ask the laboratory for report-specific confirmation if coverage is unclear.
What if another laboratory performed one test?
Identify that performing laboratory and verify its current accreditation and scope independently. The issuing laboratory’s accreditation does not automatically cover another facility’s work.
Does a laboratory logo prove the report is authentic?
No. Authenticate the report through the laboratory when possible, using the report number, portal or verification link.
Is a “Pass” result enough?
No. Review the numerical or qualitative result, unit, method, reporting limit, specification, sample identity and lot.
Does accreditation prove that sampling was representative?
Not by itself. Review who collected the sample, how it was selected, chain of custody and the lot controls connecting the sample to the product.
Does a heavy-metal scope cover microbial testing?
No. They are different testing disciplines and must be checked separately.
Does a botanical-powder scope automatically cover extracts or liquids?
Do not assume it does. Confirm the matrix and method with the laboratory or accreditation body.
Does accreditation show that a product is ordinary leaf rather than concentrated 7-OH?
No. Product form, ingredients, alkaloid testing and formulation evidence answer that question. Accreditation addresses the laboratory activity within scope.
How often should Kiody recheck a laboratory?
At minimum, when accreditation or scope documents change or expire and whenever the location, method, matrix, subcontractor or report format changes. A current directory check should also be part of routine COA release review.
Bottom line
“Tested by an ISO laboratory” is a starting claim, not a completed verification.
A reviewable evidence chain connects the full COA to the laboratory, the laboratory to its accreditation body, and the claimed tests to the active scope for the correct location. It also separates accredited from non-accredited work, identifies outside laboratories and preserves the product, lot, matrix, method, result, unit and reporting limit.
Accreditation can strengthen confidence in laboratory competence and consistent operation. It cannot prove FDA approval, universal safety, representative sampling or that every test a laboratory offers is accredited. A responsible seller can build trust by showing the exact evidence, stating its limits and keeping botanical leaf clearly separate from concentrated or synthetic products.
