Important notice. Kratom Thai Exports supplies business buyers only (B2B). You must be 18 or older to use this site. The content on this page is for general market and research information. It is not medical advice and must not be used to diagnose, treat, cure or prevent any condition. These statements have not been evaluated by the U.S. Food and Drug Administration (FDA). Research findings are summarised from the cited sources and describe what those studies reported; they are not claims about any product we supply. Laws on kratom and its alkaloids, including 7-hydroxymitragynine (7-OH), differ by country, state and city and change often. Check the laws in your jurisdiction and with your import authority before buying, importing or selling.
Short answer: To vet a Thai kratom supplier, confirm the exporting company holds a current ONCB export licence in its own name, is Thai-registered with at least two-thirds Thai directors, partners or shareholders, and can show an ONCB notification receipt code and a Department of Agriculture ePhyto certificate per shipment. Then check lot COAs, traceability and destination rules before you pay.
If you are working out how to vet a kratom supplier, generic checklists cover quality and capacity. This guide adds the Thai legal checks that decide whether a shipment can leave the country. Rules are as published in the linked sources on 16 October 2026.
Why does Thai kratom supplier verification start with the law?
Under Section 10 of the Kratom Plant Act B.E. 2565 (2022), anyone who wishes to import or export kratom leaves must obtain a licence and must notify the licensor before each import or export. Section 32 sets a penalty of up to one year of imprisonment, a fine of up to THB 100,000, or both, for exporting without a licence (Kratom Plant Act).
DeeMED Consulting, a Bangkok compliance firm, notes the licence is tied to the exporting entity, not the product, and advises buyers to make licence verification a condition of the purchase contract (DeeMED). Kratom supplier due diligence therefore checks the company first.

1. Do you hold a current ONCB kratom export licence in your company’s name?
Why it matters: the licence is issued by the licensor, the Secretary-General of the Narcotics Control Board, and lasts five years from issue (Sections 10 and 12, Kratom Plant Act). To verify a Thai kratom exporter licence, use the ONCB kratom licensing service page (in Thai), which links to a search system for kratom leaf export licences (ONCB).
Good answer: a licence copy showing holder name, number and issue date, with the holder matching the exporter on your pro forma invoice.
2. Is your company registered in Thailand, and does it meet the two-thirds Thai rule?
Why it matters: a company applicant must be registered under Thai law, have an office in Thailand, and have at least two-thirds of its directors, partners or shareholders of Thai nationality (Section 11, Kratom Plant Act). DeeMED notes this rules out majority foreign-owned entities applying directly, so most foreign buyers work through a Thai-majority exporter (DeeMED).
Good answer: a registration number you can check on the Department of Business Development (DBD) DataWarehouse, which shows company status, directors, registered capital and address. Shareholding percentages can be requested from a DBD branch for a fee (Logan & Partners).
3. Who will be the exporter of record on the documents?
Why it matters: a Thai business can grow, process and sell kratom leaf domestically without an ONCB licence; the obligation only attaches at import or export (DeeMED). A genuine farm or processor may still not be a licensed exporter.
Good answer: the seller names the licensed entity that will appear on the invoice, ONCB notification and phytosanitary certificate. If a broker or agent is involved, put each party’s role in the contract (see how to source bulk kratom from Thailand).
4. Will you file the ONCB pre-shipment notification and share the receipt code?
Why it matters: each shipment must be notified through the ONCB National Single Window (NSW) at least seven business days before export, stating quantity, lot numbers, port and vessel or flight. Within three business days the ONCB issues a notification receipt code that customs officers use to validate clearance. Failing to lodge the notice is a separate offence, with an administrative fine and possible licence suspension (Tilleke & Gibbins).
Good answer: the notice period is built into your timeline, and the receipt code arrives with the shipping documents, quantities and lot numbers matching your invoice. Our kratom wholesale MOQ and lead time guide shows where this stage sits.
5. Can you issue a Department of Agriculture phytosanitary certificate through ePhyto?
Why it matters: kratom leaf is plant material, so exporters typically also need a phytosanitary certificate from Thailand’s Department of Agriculture (DoA), issued through the ePhyto system, on top of the ONCB licence and notification (DeeMED). Since 1 October 2022 the DoA issues only its new format: watermarked paper, a number starting with TH followed by ten digits, and a QR code in the top-left corner so inspectors can verify it (IPPC).
Good answer: a redacted certificate from a recent shipment in that format.
6. Does your ONCB export plan cover my volumes and destination?
Why it matters: the licence application includes a 12-month forecast with projected volumes per quarter, destination country and intended end-use (Tilleke & Gibbins). The plan covers one year at a time, and DeeMED advises exporters to refile it when actual shipments no longer match what was declared (DeeMED).
Good answer: confirmation that your volumes and destination fit the plan on file, or will before your first order.
7. Can you provide lot-specific COAs from an independent laboratory?
Why it matters: DeeMED reports that US buyers expect batch-by-batch third-party testing for heavy metals (lead, arsenic, cadmium and mercury at minimum) and microbial contamination (Salmonella, E. coli and total yeast and mold), plus documented mitragynine content (DeeMED).
Good answer: a certificate of analysis (COA) naming the lab, method and a lot number matching the packaging and invoice, and no objection to you retesting at your own lab.
8. Are your products free of added or concentrated 7-OH?
Why it matters: this is a regulatory screening point. Thailand’s 2025 ministerial regulation defines kratom leaves as fresh or dried leaves in their natural, unprocessed state, with no extracts, concentrates or infused products (Tilleke & Gibbins). In the US, the DEA’s 14 October 2026 notice of intent proposes temporary Schedule I control of 7-OH and mitragynine pseudoindoxyl at greater than 1 mg per gram in solid forms, or where mitragynine divided by those compounds is less than 100, with an order on or after 13 November 2026 (Federal Register). See our DEA 7-OH notice summary.
Good answer: written confirmation of no added or concentrated 7-OH, and COAs reporting both mitragynine and 7-OH so you can check the thresholds. Finished products such as capsules follow a separate Thai FDA track (DeeMED).
9. Can you trace each lot to its harvest, and which certifications can you prove?
Why it matters: Thailand has no government-mandated Good Agricultural and Collection Practice (GACP) standard for kratom, and DeeMED reports buyers expect records linking a shipment to a harvest lot and processing date (DeeMED). The American Kratom Association’s GMP program is a facility and process certification, not a product certification, and requires an annual independent audit (AKA).
Good answer: lot records from harvest to packing, and a certificate and auditor name for any certification claimed, which you can confirm with the issuer.
10. Will your documents match, and do you check my market’s rules?
Why it matters: mismatched names, weights or lot numbers across documents are a common cause of customs delays (see our kratom export documents and permits guide). In the US, FDA Import Alert 54-15 lets districts detain, without physical examination, kratom dietary supplements and bulk dietary ingredients from firms on its red list (FDA).
Good answer: drafts of every document before shipment, factual labels with no effect claims, and a supplier who asks where the goods are going. Check kratom legal status in Thailand and your import rules before ordering.

Frequently asked questions
How do I verify a Thai kratom exporter’s licence?
Ask for a copy of the ONCB kratom export licence and check the holder name, licence number and issue date. A licence runs five years from issue. The ONCB kratom licensing service page, in Thai, links to a search system for export licences. The holder must match the exporter on your invoice.
Can a foreign-owned company hold a Thai kratom export licence?
Not as a majority foreign-owned company. Section 11 of the Kratom Plant Act requires a company applicant to be registered under Thai law, keep an office in Thailand and have at least two-thirds Thai directors, partners or shareholders. Most foreign buyers therefore buy through a licensed Thai-majority exporter.
What is an ONCB notification receipt code?
It is the reference the ONCB issues after an exporter files the pre-shipment notification through the National Single Window. The notification is due at least seven business days before export, and the code follows within about three business days. Customs officers use it to validate clearance, so ask for it with every shipment.
How can I check a Thai phytosanitary certificate?
Thailand’s Department of Agriculture issues phytosanitary certificates through its ePhyto system. Since 1 October 2022 only the new format is issued: watermarked paper, a certificate number that starts with TH followed by ten digits, and a QR code in the top-left corner that lets inspectors verify the document.
