Japan Customs Clearance for Thai Goods (2026)
Japanese clearance is fast - often same-day - but only when the documents are complete before arrival. This is the sequence we run for clients importing from Thailand.
Who is the importer of record
| Situation | Importer of record | Notes |
|---|---|---|
| Japanese company buying | The company itself | Needs a corporate number and a customs broker |
| Overseas seller shipping to a Japanese marketplace | Attorney for Customs Procedures (ACP) | Required for non-resident importers |
| Sample or trade-fair goods | Company or ATA carnet | Carnet avoids duty and tax on temporary import |
Non-resident importers must appoint an ACP. Marketplace sellers who skip this step are the most common cause of shipments held at Narita and Kansai.
Document pack
- Commercial invoice with unit prices and Incoterm
- Packing list with net and gross weights
- Bill of lading or air waybill
- Certificate of origin (only if claiming JTEPA, AJCEP or RCEP)
- Product-specific permits: Food Sanitation Act notification, MIC/TELEC for radio devices, PSE for listed electrical goods
The NACCS filing
Your broker files the import declaration through NACCS, Japan's electronic customs system. Three outcomes:
| Channel | What happens | Typical time |
|---|---|---|
| Immediate release | Declaration accepted electronically | Same day |
| Document examination | Broker submits supporting papers | 1-2 days |
| Physical inspection | Container devanned or scanned | 2-5 days |
AEO-certified brokers and repeat importers with clean histories see immediate release far more often, which is a good reason to consolidate rather than spread shipments across brokers.
Duty and tax calculation
Japan assesses duty on CIF value. Consumption tax of 10% is then charged on CIF plus duty. A worked example on a USD 50,000 CIF shipment at 3% duty:
| Line | Amount (USD) |
|---|---|
| CIF value | 50,000 |
| Customs duty at 3% | 1,500 |
| Taxable base | 51,500 |
| Consumption tax at 10% | 5,150 |
| Cash out at import | 6,650 |
Registered businesses recover the consumption tax; the duty is a real cost. If you import monthly, ask your broker about the deferred payment account, which moves tax settlement to the following month and frees working capital.
Valuation traps
- Tooling and mould charges paid separately are dutiable assists and must be declared.
- Royalties tied to the imported goods form part of customs value.
- Free replacement parts still need a declared value for customs purposes.
Declaring these voluntarily is cheap. Having Japan Customs find them in a post-clearance audit is not.
Where things go wrong with Thai shipments
Fumigation and wood packaging are the recurring issue. Japan enforces ISPM 15 strictly, and Thai factories often reuse untreated pallets. Specify heat-treated, stamped pallets in the purchase order, and require a photo of the stamp before container loading. We inspect this at loading as standard.

FAQ
Can a foreign company be the importer of record in Japan? Not directly. A non-resident importer must appoint an Attorney for Customs Procedures who assumes the filing and tax responsibilities in Japan.
How fast is Japan customs clearance? Sea freight is commonly cleared within one working day of arrival when documents are pre-filed; air freight is often the same day.
What is the consumption tax on imports? 10% on CIF plus duty, paid at import and recoverable by registered taxable businesses under the qualified invoice system.
Do I need fumigation for Thai shipments? Wooden packaging must comply with ISPM 15 - heat treated or fumigated and stamped. The goods themselves usually do not require treatment unless they are plant based.
What happens if the certificate of origin arrives late? You can pay MFN duty and file for a refund with a retroactively issued certificate, but the window is limited. Getting the form with the documents is far cheaper.
