Thailand's Medical Device Import Permit Requirements Explained

Foreign manufacturers new to the Thai market frequently assume that a device registration certificate is all they need before shipping product. It is not. The Medical Device Act B.E. 2551 (2008) establishes two separate permissions that must both be in place before a device can legally enter the country, and confusing one for the other is one of the more expensive mistakes a first-time exporter can make.

Two Separate Permissions, Not One

The Medical Device Act, administered by the Food and Drug Administration under the Ministry of Public Health, treats registration and import authorization as distinct legal events. Device registration is a product-level licence confirming that a specific model or product family meets Thai safety, efficacy, and labelling standards. An import permit, ใบอนุญาตนำเข้า, is a separate transaction-level authorization that allows a licensed Thai importer to physically move registered devices across the border. Holding one without the other accomplishes nothing at customs: a valid registration with no corresponding import permit will not clear a shipment, and an import permit held by an entity that never obtained its importer licence from the Medical Devices Control Division (MDCD) is void from the start.

The 2019 amendment (B.E. 2562) sharpened MDCD's enforcement powers and made clear that every party in the distribution chain, importers, distributors, and sellers alike, must maintain traceable records. Regulators can request shipment-level documentation at any point along the chain, not only when goods first arrive.

Who Is Allowed to Hold an Import Permit

Only a Thailand-established, MDCD-licensed importer can hold an import permit; the foreign manufacturer cannot import directly, regardless of whether it holds the underlying device registration. This is a deliberate structural choice, placing legal accountability for product safety, labelling, and post-market obligations on an entity physically present and reachable in Thailand. To earn that importer licence, a company needs a physical Thai premises meeting storage and handling standards appropriate to the device's risk class, subject to MDCD inspection both before licensing and at any later point. It must also name a responsible person (RP) on the licence, an individual accountable to MDCD for all activities carried out under it and who must meet the FDA's education and experience thresholds.

Once licensed, the importer can apply for import permits on behalf of the registration holder, or under a Letter of Authorization (LOA) issued by the foreign manufacturer. The RP named on the importer licence needs to match the name on the device registration, or the LOA needs to explicitly authorize the importer to act. A mismatch here is one of the single most common causes of permit rejection, and it is entirely avoidable with basic document hygiene.

Per-Shipment Versus Annual Permits

Thailand offers two permit structures, and the choice affects both paperwork volume and cash-flow planning. A per-shipment permit covers one consignment of a specified device, quantity, and value, and requires a fresh application with supporting documents each time. This suits companies shipping infrequently or still testing Thai market demand. An annual permit covers multiple shipments of the same registered device across a 12-month validity window; the importer still logs each shipment against the ceiling, but the per-transaction paperwork burden drops considerably for companies with predictable, established volume.

Neither option removes the need for shipment-level documentation. Customs declarations, commercial invoices, packing lists, and the permit reference all need to travel with every consignment, and MDCD cross-checks these against customs records. A discrepancy between declared quantities and the permit's approved ceiling triggers a hold at the port of entry regardless of which permit type is in use.

What MDCD Wants to See at Application

Applications go through MDCD's e-submission portal, or in paper form at the FDA's Nonthaburi offices for certain categories, with the licensed importer as the applicant of record. Four items typically accompany the application: the current, valid Thai device registration certificate (with evidence of a pending renewal filing if applicable), a current LOA from the manufacturer naming the importer exactly as it appears on the importer licence, the commercial invoice and packing list showing device model, quantity, unit value, and HS code for per-shipment applications, and a copy of the importer's own current MDCD-issued licence.

A fully documented, standard application usually processes in one to three working days. An incomplete or inconsistent application does not simply wait in a queue; it gets returned for correction and resubmission, resetting the clock entirely. For time-sensitive shipments, the safer approach is submitting a complete package before goods even leave the country of origin.

What Actually Causes Delays and Rejections

The single most frequent problem is attempting to import a device that has no Thai registration at all. Unregistered devices cannot enter the country except through two narrow exemptions, clinical research under an ethics-committee-approved protocol and compassionate use for an individual patient in urgent need, neither of which applies to routine commercial trade. Attempting routine importation of an unregistered device as though it were registered is an offence under the Act, not a paperwork oversight.

An expired or misaddressed LOA is the second most common issue. Manufacturers on an annual LOA renewal cycle sometimes miss the expiry date, leaving the importer without valid authorization when the application is filed. An LOA issued to a parent company rather than the exact Thai legal entity on the importer licence will be rejected even where the underlying commercial relationship is obvious. A mismatched HS code is the third recurring problem: when product descriptions get updated commercially after registration, the invoice's declared code can drift from the code used at registration, and MDCD will hold goods at customs while the discrepancy is resolved. Finally, if the RP on the importer licence no longer matches the RP on the device registration, MDCD will query the application; any RP change on either record needs a formal amendment filed before new permits can be requested.

The Cost of Getting This Wrong

Importing without a valid permit, or on the basis of incorrect information, is a criminal offence under the Medical Device Act, carrying fines and, in serious cases, imprisonment for the individuals responsible, in addition to corporate liability. At the practical level, unpermitted goods are subject to seizure at the port of entry, destruction, or return at the importer's expense, and the importer's licence itself can be suspended or revoked, which shuts down import activity for its entire product portfolio, not just the device involved. Rebuilding an importer licence after revocation takes a prolonged review and is not guaranteed to succeed.

For the foreign manufacturer, the fallout does not stop at the shipment. MDCD can place holds on the manufacturer's existing registrations pending investigation, and renewal applications filed during active enforcement tend to get deprioritized. The maintenance cost of doing this correctly, a qualified licensed importer, current LOAs, accurate per-shipment paperwork, is consistently lower than the cost of one enforcement action. Companies entering Thailand for the first time should treat the import permit requirement as a core piece of market access planning, addressed well before product is ready to ship, and DeeMED Consulting works with foreign manufacturers to structure the importer relationship correctly from the start, including licensed importer and responsible person arrangements that keep registration and import records aligned.
