Customs clearance in Thailand is frequently treated as a standalone administrative process — something that happens between the port and the warehouse. For companies importing temperature-sensitive products, or operating FTZ or bonded warehouse structures, this separation creates problems.
MON operates its own customs clearance capability in Thailand, integrated with cold storage and delivery operations. This means the inbound flow — from port or airport through customs to cold storage to delivery — is managed as one connected operation rather than a series of handoffs between separate providers.

📌Why customs clearance matters more for cold chain imports
For ambient products, a customs clearance delay of one or two days is an inconvenience. For frozen and chilled imports, it is a quality risk.
What happens during customs delays for temperature-sensitive cargo:
Port and airport cold storage facilities exist in Thailand, but they vary in quality and are not always aligned with the temperature requirements of specific products. Cargo that sits in port cold storage longer than planned — due to documentation problems, inspection requirements, or FDA hold — is exposed to temperature management that the importer has limited control over.
The most common causes of cold chain import delays at customs:
📌FDA — what it is and what MON can and cannot do
📌FDA — what it is and what MON can and cannot do
Thailand's Food and Drug Administration (FDA) regulates the import and sale of food, beverages, cosmetics, pharmaceuticals, medical devices, and health products. Most food and beverage products imported into Thailand require FDA registration or notification before the first shipment arrives.
🛃What this means in practice:
FDA registration is not something that can be done after the shipment arrives — it must be completed before import begins
The registration process takes weeks to months depending on the product category
Importing without the required FDA registration results in the shipment being held at customs
🛃What MON can support:
Explaining the FDA registration process for food and beverage categories
Identifying whether your product requires registration, notification, or neither
Advising on the documentation typically required for the registration process
Referring to qualified FDA consultants who handle the registration process directly
🛃What MON does not do:
Act as the FDA registration applicant or agent
Guarantee registration outcomes or timelines
For companies importing food, beverages, or other regulated products into Thailand for the first time, starting the FDA process early — well before the first planned shipment — is essential.
📌The integrated inbound flow — how MON connects customs to cold storage
📌The integrated inbound flow — how MON connects customs to cold storage
For temperature-sensitive imports, the sequence from port to cold storage needs to be managed as one operation:
The critical point is the transition from port cold storage to MON cold storage at the moment of clearance. When customs clearance and cold storage are managed by different companies, coordination at this transition point is frequently poor — cargo waits in ambient or inadequately controlled conditions between clearance and transfer.
When MON handles both customs clearance and cold storage, this transition is managed as an internal operational step rather than a handoff between separate providers.
📌FTZ customs procedures
📌FTZ customs procedures
For companies using MON's FTZ facility (opening June 2026), customs procedures for inbound and outbound operations are different from standard import clearance.
FTZ inbound: Goods enter the FTZ under a specific customs procedure that suspends duty and VAT. MON handles the FTZ inbound documentation and customs coordination.
FTZ domestic release: When goods move from the FTZ to the Thai domestic market, a customs clearance process is triggered at that point. Duty and VAT are assessed based on the quantity actually released for domestic sale.
FTZ re-export: Goods leaving the FTZ for re-export to other countries follow a re-export customs procedure. Duty and VAT are not assessed on re-exported volume.
MON supports all three procedures as part of FTZ operations.
※ Specific customs and tax treatment should be confirmed with a qualified customs broker and tax advisor. MON provides operational support — final regulatory determinations require specialist advice.

To assess what customs support is needed for your operation, it helps to clarify:
Product category and whether FDA registration is likely required
Import origin and trade route
Whether the operation is standard import, FTZ, or bonded warehouse
Current customs clearance arrangement and specific problems being experienced
Temperature requirements for the imported product
Timeline for first or next shipment
