How to Vet a Freight Forwarder for Regulated Cargo in Thailand

Most companies choose a freight forwarder in Thailand the way they choose any vendor: on price, transit time, and a friendly sales call. For regulated cargo, that approach is a liability. A forwarder that cannot produce a current GDP certificate, cannot file through the National Single Window, has no bonded warehouse relationship, and has never touched a WoAo3 transit permit will not tell you that during onboarding. You find out when a shipment sits in a bonded area for three weeks because the paperwork was filed wrong, or when a Thai FDA inspector flags a distribution record gap during an audit that traces back to a subcontracted trucking leg nobody vetted. Vetting a forwarder for regulated cargo in Thailand means checking specific licenses and system access against the specific regulation that governs your product category, not reading testimonials.

GDP-certified warehousing for pharmaceutical and health product cargo

If any part of your supply chain touches modern drugs, active pharmaceutical ingredients, or temperature-sensitive health products, the forwarder's warehouse and transport operation needs to be certified against Thailand's TH-GDP standard, the Good Distribution Practice notification the Thai FDA issued in 2021 and brought into full effect on January 1, 2022. TH-GDP is not a courtesy standard; it applies by law to manufacturers, importers, distributors, third-party logistics providers, and transporters anywhere in the drug supply chain, and Thai FDA inspectors audit against it during facility license renewals. A forwarder without TH-GDP certification is not simply "less polished"; it is legally unable to serve as a compliant link in a licensed importer's distribution chain, and any drug that passes through a non-compliant warehouse or vehicle creates a documentation gap that can jeopardize the importer's own FDA license, not just the shipment.

When vetting a forwarder on this point, ask to see the actual TH-GDP certificate, not a general ISO or GMP certificate, and confirm the certificate's scope: some forwarders hold GDP certification for warehousing but subcontract the last-mile trucking leg to an uncertified carrier, which reintroduces the same compliance gap. Ask specifically who operates the vehicles between the bonded warehouse and final delivery, and whether that operator is named on the same certificate or a separate one. Ask how temperature and humidity records are maintained during storage and in transit, since TH-GDP requires documented environmental monitoring, not just a working air conditioner. If the forwarder cannot produce the certificate on request or hedges about scope, that alone is disqualifying for pharmaceutical or health-product freight.

National Single Window filing capability and License Per Invoice processing

Since May 2025, Thailand's FDA and Customs Department operate an integrated electronic control system that links the Customs Department's Controlled Goods Database to the Thai National Single Window (Thai NSW) for health products, covering pharmaceuticals, medical devices, food supplements, cosmetics, herbal products, and hazardous substances. Under this system, every regulated shipment requires a License Per Invoice (LPI), an FDA-issued electronic notice tied to the specific invoice, filed through Thai NSW before Customs will release the goods. This replaced a more manual, paper-adjacent process, and forwarders who have not updated their filing systems and staff training since the 2025 rollout are still working from outdated procedures that generate rejected or delayed LPI submissions.

A forwarder capable of handling regulated cargo needs demonstrated, current experience filing LPIs through Thai NSW, not just general customs brokerage experience. Ask how many LPI filings they have processed since the May 2025 rollout, what health product categories those filings covered, and what their internal process is for reconciling invoice-level product classification with the FDA's controlled goods database before submission, since a mismatch between invoice description and FDA product registration is the single most common cause of an LPI rejection. Also ask whether they file LPIs in-house or route them through a third-party customs broker; if it is the latter, you are really vetting that broker's Thai NSW competence, and you should ask to speak with them directly rather than taking the forwarder's word for their reliability.

Bonded warehouse or Free Zone access under the Customs Act

Regulated cargo frequently needs to sit in a controlled, duty-suspended space while FDA clearance, licensing, or re-export documentation is finalized, and Thailand's Customs Act framework governs which facilities are legally permitted to hold uncleared goods: bonded warehouses licensed under the Customs Department and Free Zones established for manufacturing or distribution. A forwarder without direct access to a licensed bonded facility, or one who quietly stores uncleared regulated goods in an ordinary commercial warehouse while paperwork is pending, is operating outside the law and exposing your shipment to seizure risk if Customs conducts a spot check.

Confirm the specific bonded warehouse or Free Zone the forwarder uses, and verify independently that the facility appears on the Customs Department's list of licensed bonded warehouses rather than accepting the forwarder's assurance. Ask whether the facility's bonded license covers your product category; not every bonded warehouse license extends to hazardous substances or pharmaceuticals, since those require additional sub-licensing tied to the underlying product regulation. For companies running recurring import volumes, ask whether the forwarder has standing Free Zone arrangements that would let you defer duty and taxes on inventory awaiting distribution, which is a meaningful cash-flow advantage over routine port clearance for anyone holding regulated stock in Thailand for more than a few days.

DIW hazardous-substance transit licensing under the Hazardous Substance Act

Companies moving industrial chemicals, certain cosmetic raw materials, or other Type 3 hazardous substances through Thailand, whether importing for domestic use or transiting goods to a third country, need a forwarder holding the correct permit under the Hazardous Substance Act (No. 4) B.E. 2562. Type 3 hazardous substances require a license from the Department of Industrial Works (DIW) to produce, import, export, possess, or transit, filed on form WoAo3, and a separate transit permit specifically covers goods moving through Thai territory without entering domestic commerce. A forwarder handling this cargo without a valid WoAo3-based transit license is not a paperwork shortcut; it is a criminal exposure for both the forwarder and the cargo owner, since the Hazardous Substance Act carries penal liability, not just administrative fines, for unlicensed handling of Type 3 substances.

Ask the forwarder directly whether they hold an active DIW transit permit for the specific hazardous substance sub-list your product falls under, since permits are substance-category-specific rather than blanket authorizations, and confirm the permit is current rather than expired or in renewal limbo. Ask about their financial guarantee arrangement, since Thai regulation requires transit operators for certain hazardous substance categories to post a minimum guarantee, currently 500,000 THB for sub-list 5.2 transit, as a condition of the permit remaining valid. If your cargo includes hazardous substances alongside pharmaceuticals or supplements in a single shipment, confirm the forwarder can keep the two regulatory streams properly documented and physically segregated in the warehouse, since combining them under a single generic handling process is a common source of DIW compliance findings.

Cold-chain data-logger integration for temperature-sensitive cargo

Vaccines, biologics, certain supplements, and temperature-sensitive medical devices require continuous, documented temperature control from origin to final delivery, and TH-GDP explicitly requires environmental monitoring records as part of the distribution file. A forwarder that verbally confirms "we have refrigerated trucks" without integrated, exportable data-logger records is not meeting the documentation standard Thai FDA inspectors expect, and a gap in the temperature log, even for cargo that arrived visually fine, can trigger a rejected batch or a compliance finding during an audit.

Ask specifically what data-logger system the forwarder uses, whether the logger travels with the shipment or is fixed to the vehicle, and whether you receive the raw temperature log as an exportable file tied to your shipment reference, not a summary "within range" confirmation after the fact. Ask how excursions are handled procedurally: does the forwarder have a documented deviation protocol that flags an excursion in real time, or do they only discover it when reviewing the log after delivery. For any client shipping temperature-sensitive regulated cargo, this is worth checking before the first shipment ever moves, not after a batch arrives with an unexplained gap in its record.

Quick reference: what to request before signing

• Current TH-GDP certificate, with scope confirmed to cover warehousing and the actual transport vehicles used
• Evidence of Thai NSW filing activity and License Per Invoice processing since the May 2025 rollout
• Name and Customs Department listing status of the specific bonded warehouse or Free Zone facility used
• Active DIW WoAo3 transit permit matched to your hazardous substance sub-list, if applicable
• Sample exportable data-logger report from a prior shipment, not a verbal cold-chain assurance

DeeMED works alongside a small number of vetted logistics partners for clients who need their regulatory licensing and their physical supply chain to move in sync, and in some engagements we coordinate freight and customs filing directly as part of a broader compliance mandate, since a License Per Invoice filed against the wrong FDA registration number causes the same delay whether the mistake originates with the forwarder or the client. If you are evaluating a forwarder for regulated cargo and want a second set of eyes on their certifications before you commit volume to them, that review is a natural extension of the licensing work we already do.
