Understanding COA: Why Lab-Tested Kratom Matters

A Certificate of Analysis (COA) is essential for legally importing kratom into Europe and beyond. Learn why COAs protect importers, ensure compliance, and guarantee quality with Molybest’s third-party lab testing.

Why Lab Testing Matters
---------------------------------------------------------
In today’s regulatory environment, transparency is no longer optional—especially when it comes to importing botanical products like kratom (Mitragyna speciosa). Whether the purpose is resale, research, or manufacturing, buyers are increasingly required to verify safety and quality through standardized testing. The Certificate of Analysis (COA) has become central to this process. For European importers in particular, working with a supplier that can provide independent and verifiable COAs is not only a best practice but also a legal safeguard. As Thailand’s first licensed kratom exporter, Molybest ensures that every batch shipped abroad includes full laboratory validation and regulatory documentation.


---------------------------------------------------------
What a COA Includes
---------------------------------------------------------
A Certificate of Analysis is a formal document issued by a laboratory that verifies the composition and safety of a product. For kratom, a COA typically reports on alkaloid content, including mitragynine and 7-hydroxymitragynine levels, microbial safety indicators such as E. coli and salmonella, heavy metal screening for lead, mercury, cadmium, and arsenic, as well as moisture content and other stability markers. These results determine whether the product meets legal thresholds for importation and complies with international safety standards.


---------------------------------------------------------
Why Importers Rely on COAs
---------------------------------------------------------
For importers, the COA serves multiple purposes at once. Customs authorities within the EU and other regulated regions often require lab documentation before botanical shipments can be released. For businesses seeking product registration or integration into supplements, COAs are part of the regulatory checklist. They also provide brand protection, as lab-tested kratom reduces liability risks and demonstrates a clear commitment to consumer safety. Finally, they help strengthen client confidence by assuring partners and regulators alike that the product is authentic, compliant, and safe. Without proper lab reports, importers face a high risk of seizure, rejection, or reputational damage.

Molybest’s Testing Process
---------------------------------------------------------
At Molybest, every batch of kratom is tested through certified third-party laboratories before it leaves Thailand. For confidentiality reasons, we do not disclose the identities of our lab partners, but all results are fully documented and supplied alongside each shipment. Each COA includes a batch ID that corresponds directly to the physical packaging and traceability documents, ensuring a seamless link between testing data and the product itself. This system allows our clients in the Netherlands, Germany, and other approved regions to present complete compliance records during customs inspections or regulatory audits.


---------------------------------------------------------
How to Verify a COA
---------------------------------------------------------
Importers should always evaluate COAs with a critical eye. A valid report should contain the lab’s name and verifiable details, a batch number matching the shipment, a recent testing date within 30 to 90 days, specific numeric values rather than vague “pass/fail” results, and the use of official lab letterhead or a formal template. At Molybest, our COAs are designed to meet each of these criteria, and digital copies are provided to clients prior to shipment for pre-clearance with customs authorities.


---------------------------------------------------------
A Standard That Cannot Be Overlooked
---------------------------------------------------------
In modern kratom trade, lab testing is not an optional extra—it is an absolute requirement. For importers who want to grow responsibly, comply with evolving regulations, and maintain long-term business credibility, the COA represents both legal protection and a competitive advantage. By sourcing from Molybest, importers are guaranteed licensed, transparent, and fully lab-verified Thai kratom in every shipment.
