Can we save on duty when shipping equipment and materials from China?
Possibly. China-ASEAN agreement rates and BOI duty-free import are both routes that may apply. Get the HS classification right first, then pick the route.
What happens if the HS classification is wrong?
At best you overpay duty; at worst the entry is treated as a false declaration. Classification needs a documented basis and a file you can produce later, not a guess.
What is Form E, and do we have to get one?
It is one of the certificates of origin commonly used between China and Thailand; where the conditions are met it gives access to the agreement rate. Whether it is worth obtaining, and how it fits the customs declaration, is judged shipment by shipment.
Can BOI duty exemption and Form E be used at the same time?
One shipment is normally declared under whichever single route is better, not both. The BOI exemption also has a boundary, and taxes outside its scope are still payable. Which combination costs least is worked out shipment by shipment, against the tariff code of the goods.
Why does the HS code matter so much for goods imported into Thailand?
In one line: in Thailand, the tax lands on the code. What actually goes into the customs entry is an 11-digit tariff number. The first 8 digits set the duty rate; the last 3 drive licensing and control requirements. Eligibility under a BOI exemption list or under Form E is also matched against the code. Get the code wrong and it means back duty plus penalties, and Customs can look back at earlier entries. Where a case is unclear, check it with our consultants first.
Can the HS code used on Chinese export declarations be used directly in Thailand?
The answer: only the first 6 digits carry over. Those 6 are the international layer set by the World Customs Organization and are the same in China and Thailand. From the 7th digit on, China uses its own subdivisions, while Thailand uses the ASEAN AHTN 8 digits plus 3 local digits, 11 in total. Padding a Chinese code with zeros for a Thai entry will often land on a line that does not exist in the system; clearance is rejected and the goods have to be reclassified against the Thai tariff.
What is an AHTN code, and how does it relate to HS?
AHTN is the ASEAN Harmonised Tariff Nomenclature: below the international 6-digit HS, the ten ASEAN countries add a further common 2 digits, giving an 8-digit code they all share. It tracks the HS version, so the current AHTN 2022 is built on HS 2022. The first 8 digits of a Thai 11-digit tariff number are the AHTN code and the first 6 are the international HS, so the levels nest and the prefixes match.
Where can the Thai 11-digit tariff number be looked up?
Use official channels only. The final check is the Thai Customs Integrated Tariff Database (ITD) at itd.customs.go.th, the one official live source that gives the full 11-digit code together with the statutory rate for each column. For day-to-day checking, the official trade portal thailandntr.com can be used alongside it. When you look a code up, do not read the statutory ceiling as the rate you will actually pay; the two are often far apart. Where a case is unclear, check it with our consultants.
How do we settle a product's customs code before shipping to Thailand?
The conclusion first: do not pick a code from experience, work down the official rules step by step. Start by pinning down four things about the product: material, function, state of processing, and whether it is a set. Then apply the General Interpretative Rules (GIR) level by level to reach the ASEAN 8-digit AHTN code. Finally check the 11-digit code and the rate against the official Thai Customs tariff database. For high-value goods, or goods imported repeatedly, apply for an advance classification ruling beforehand to lock the code down. Individual cases should be checked with our consultants.
What are the consequences of declaring the wrong customs code?
They are concrete. Back duty plus a penalty is the standard outcome, and Thai Customs can generally look back 2 years, up to 5 years in serious cases. Declare too low a rate and you pay the difference plus a fine. If the code does not match across the documents, the goods can sit in clearance waiting for an amendment, and demurrage costs climb with it. For a company importing under a BOI exemption it bites harder: if the code does not match the approved list, duty-free release itself can be held up. The penalties that apply are as set out in the latest official announcements; individual cases should be checked with our consultants.
Does sending the entry data to Customs mean the import declaration is complete?
Not yet. The system first runs three preliminary validations — against the reference data files, against approval and licence data under the relevant laws, and against the vessel manifest. Only when all three pass does it issue a 14-digit electronic entry number and move the entry to “ready to pay”, and that is the point at which the declaration counts as properly lodged with Customs. Data can be sent before the vessel arrives, which is a useful way to clear data-level errors early, but the system will not issue a number until the vessel arrival report has gone through successfully — the clock really starts there, so don't build that time back into the production schedule.
Do we know at the time of declaration whether the shipment will be inspected?
No. Inspection instructions are issued by the system under risk-management rules, and the determination happens after payment or guarantee is completed, not at the moment of lodgement — so you cannot sequence it as “see whether we get inspected, then decide how to pay”. Two further points: the determination is made by the system from a risk profile rather than decided on the spot by an officer, which means this line can be managed over time; and when a shipment goes to the red line the system only sends the cargo data to the warehouse — contacting the warehouse and arranging the physical inspection is still the importer's or broker's own job.
With a BOI duty exemption, what actually proves the shipment was cleared duty-free?
The separate exemption number the system issues. Holding a promotion certificate does not make a shipment duty-free by itself — the shipment has to go through the exemption route in the system and end up as an “exempted entry”, and that number is what filing, reconciliation and any later query all rely on. The entry also has a privileges group, where the right category has to be ticked and the investment promotion certificate number filled in. Get that field wrong or leave it blank and the system cannot reconcile the exemption, so what should have run automatically becomes an exception to be worked through by hand.
The export entry has been approved — does that mean the goods are exported?
No. VAT zero-rating on exports, raw-material reconciliation under RMTS and the start of any refund clock all turn on the actual export date, which a Customs officer enters into the system after the fact, and that depends on the carrier completing its departure report: by sea, after the outbound vessel report; by air, after the outbound aircraft report; by road, when the vehicle submits the movement document at the border checkpoint. Other modes of transport each have their own point of reference. Export entries that straddle a month-end need the actual export date checked one by one — don't book them on the entry date.
Why do most of our export entries not show as “duty paid” in the system?
Because Thailand generally levies no export duty, so the large majority of entries go down the exemption route: the system issues a separate exemption number and the status is “exempted entry”, which is a different status from “duty-paid entry” — and it is acknowledged per declared item, not once for the whole entry. When reconciling, or matching entries for RMTS reconciliation, matching only on “duty paid” will miss most export entries.
We short-shipped an export. Is there still time to correct it?
It depends on timing. Within 10 days of the goods movement document being reconciled, a short shipment — where less was loaded than declared — can be corrected electronically for the portion not exported, with no fault pursued; for bulk cargo requiring a draft survey, a written application within the same 10 days can likewise be approved without fault. After 10 days both have to go through a written application, and the fault is examined along with it. The two routes are not the same: short shipment within 10 days is a self-service electronic correction, while bulk cargo still needs a written application and only gets the relief — draft survey reports are routinely slow, so bulk shippers need the result in hand inside the 10 days.
Goods leaving a bonded warehouse for domestic sale — can we just reuse the original import entry to work out the tax?
No. The elements are taken from three different points in time: the exchange rate from the date the goods entered the Kingdom; the condition of the goods, the customs value and the tariff number from the time importation was completed; and the duty rate from the day the goods are released from the bonded warehouse. Tariff revisions, agreement rate reductions and temporary rates during the storage period all change the liability, while the value and the code stay fixed at the import point. For goods held a long time, the domestic-sale calculation cannot be copied from the original import entry — at a minimum, re-check the rate in force on the release date.
Duty-free raw material used inside the zone for samples or internal testing — is tax due even though the goods never left the park?
Yes. Free zones and IEAT free zones use the same wording: using goods in the zone for consumption, or for any purpose other than the purpose for which the zone was established and the business it is licensed to operate, is treated as removing the goods from the zone. To do it lawfully, the operator in the zone prepares a transfer-for-payment import entry, applies electronically to pay the duty in full, inspection follows the same treatment as a removal from the zone, and the goods may only be consumed or otherwise used after release. “The goods never left the park” is not a defence.
The same shipment keeps getting rejected and the documents check out — where should we look first?
At the licence linkage step. Certain goods, listed by tariff number or statistical code, have their electronic licence or certificate linked through the National Single Window before the entry data can be sent — a gate that sits ahead of the entry, not a parallel track alongside it. If the linkage is not complete, a perfectly correct entry still gets rejected at the licence-data validation stage, which shows up as “the entry keeps erroring”. The lists also move: some notices keep adding items to an existing list, while later notices defer part of what was added, so whether a given code is in fact required to be linked right now cannot be settled from the latest addition list alone.
Which group of fields should document checking start with?
The party chain: consignee, importer, tax identification number. This is the one that really bites — if the consignee or the tax ID does not match the entity holding the promotion privileges, the exemption cannot be used. Next come goods description and code (a bill of lading abbreviated to the point where it cannot be matched to the promotion list will be questioned), then quantity and unit (declaring by piece against by metre makes quantity impossible to reconcile, and promoted projects also have to watch whether the cumulative quantity exceeds the total already approved on the list), then weight and volume (a clear discrepancy between packing list and bill of lading with no explanation is a high-risk item). The best time to check is before shipment — once documents have been issued, amending them means an amendment process, the other side's cooperation, and time.
