Excise Tax on Imported Goods in Thailand: How It Works

Most importers think about two taxes when they budget an import into Thailand: customs duty and VAT. For a specific group of products there is a third, and it can be the largest of the three. Excise tax applies to goods such as alcohol, tobacco, sweetened and other beverages, passenger cars, fuel, and a list of other products, and it is charged whether the goods are made in Thailand or imported. If your product is on that list and you leave excise out of your landed cost, your pricing can be wrong by a wide margin.

This guide explains how excise works for imports. It covers what excise tax is and who administers it, how it differs from customs duty, which kinds of goods are covered, how the tax is calculated, how it stacks with duty, the local tax and VAT, who files and pays at import, what the suggested retail price notification means for importers, how excise affects landed cost and pricing, and where exemptions, suspensions and refunds may apply. It closes with common mistakes and a checklist.

As with all our cost guides, we do not quote tax rates here. Excise rates are set by ministerial regulation and notification, they differ widely by product, and several categories have been restructured in recent years. Read the current rates from the Excise Department's official sources, and confirm the treatment of your specific product with the Excise Department or a licensed customs broker before you commit to a price.

What is excise tax on imported goods in Thailand?

Excise tax is a tax on specific goods and services that the state chooses to tax separately, for reasons such as health, the environment or revenue; in Thailand it is imposed under the Excise Tax Act B.E. 2560 (2017), administered by the Excise Department under the Ministry of Finance, and collected at import by the Thai Customs Department.

The key idea is that excise is about the product, not the border. A bottle of whisky or a passenger car attracts excise whether it was produced in a Thai factory or brought in from abroad, and the law aims to treat the two in a comparable way. For domestic production, the manufacturer files and pays excise with the Excise Department. For imports, the same tax is collected at the point of import, and the Customs Department collects it on the import declaration alongside customs duty and VAT, then passes it to the Excise Department.

The 2017 Act replaced several older excise laws with one framework. Among the changes that matter to importers, it moved the main value base for many goods towards a suggested retail price notified by the operator, rather than a price built up from the import cost, and it allows a tax to be charged by value, by quantity, or by both together. Ministerial regulations and notifications under the Act set the actual rates and the detailed rules for each category, and those are amended from time to time.

Because excise is a separate tax with its own law, the agency you deal with on rules and registration is the Excise Department, even though the payment for an import is made through Customs. In practice, an importer of excisable goods often needs to understand both systems: the customs side for the declaration and release, and the excise side for registration, price notification, stamps, licences and reporting.

How is excise tax different from customs duty?

Customs duty is a border tax set by the customs tariff and charged on most imports according to their tariff line, while excise is a product tax set under the Excise Tax Act and charged only on listed goods, imported or domestic; both are collected on the import declaration, but they have different laws, bases and exemptions.

The practical differences show up in four places. The first is scope. Almost every imported product has a customs tariff line and therefore a duty rate, even if that rate is zero. Excise applies only to goods named in the excise tariff, so most imports never meet it. For those that do, excise often matters more than duty.

The second is the base. Duty is normally calculated on the customs value, which in Thailand is a CIF-type value. Excise for many goods is calculated on a different base set by the Excise Tax Act, such as a notified suggested retail price, or on quantity, such as litres or alcohol content. The two taxes on the same shipment can therefore be calculated from different figures.

The third is preferences. A free trade agreement can lower or remove customs duty for originating goods with valid origin evidence. It does not remove excise, because excise is a domestic tax that applies equally to local products. A wine that enters duty-free under an agreement still attracts excise, and the same goes for a car. Importers who see a zero preference rate and assume the import is tax-free are making one of the most expensive mistakes in this area.

The fourth is administration. Duty questions, such as classification and valuation, are customs matters. Excise questions, such as which excise category applies, how the retail price is notified, and whether stamps or licences are needed, belong to the Excise Department. Our article on how import duty and VAT are calculated in Thailand covers the customs side of the calculation.

Which imported goods are subject to excise tax in Thailand?

Excise applies to goods listed in the excise tariff, which include alcoholic drinks, tobacco products, non-alcoholic beverages, passenger cars and motorcycles, fuel and petroleum products, and a range of other products such as batteries, perfumes and cosmetics, air conditioners and some luxury or environmentally sensitive items; always check whether your exact product is listed.

The list is set by law and can change, so treat any summary, including this one, as a map rather than a final answer. Broadly, the categories that importers most often meet are these:

• Alcoholic drinks: liquor, beer, wine and other fermented or distilled drinks. These also involve excise stamps, sales licences and labelling rules.
• Tobacco products: cigarettes, cigars, pipe tobacco and similar goods, with stamps, licences and strict controls.
• Non-alcoholic beverages: soft drinks, juices, energy drinks and similar products, where the tax for some drinks also takes account of sugar content.
• Vehicles: passenger cars, pick-up types in some configurations, and motorcycles, where the structure takes account of factors such as carbon dioxide emissions and powertrain type, including electric and hybrid vehicles.
• Fuel and petroleum products: petrol, diesel, lubricants and related products, usually taxed by quantity.
• Other listed goods: examples include batteries, perfumes and cosmetics, air conditioners, crystal glassware, carpets, marble and granite, yachts and pleasure boats, and ozone-depleting substances.

Two cautions apply. First, the excise category is not the same thing as the customs tariff line, and the boundaries do not always match. A product can sit in one customs heading but be caught or excluded by the excise definition for reasons such as size, use or composition. Second, some categories carry conditions or exemptions inside them, for example for goods intended for particular uses. If your product is near any of these categories, ask the Excise Department or your broker for a view before you order stock.

How is excise tax calculated on imports?

Excise can be charged ad valorem, as a percentage of a value base, specific, as an amount per unit of quantity, or as a combination of both; for many goods the value base under the Excise Tax Act is the suggested retail price notified by the operator, and the rates for each product come from ministerial regulations and notifications.

An ad valorem excise works like a percentage tax on value, but the value it uses is not necessarily the customs value. Under the 2017 Act, the main value base for many goods is the suggested retail price, which is broadly the price at which the operator expects the goods to be sold to consumers, excluding VAT, and which must be notified to the Excise Department. The Department has powers to set or adjust the base where the notified price is not considered appropriate.

A specific excise is charged per unit, such as per litre, per litre of pure alcohol, per kilogram or per piece. Fuel is the clearest example, because the tax is mainly by quantity. A specific tax behaves differently from a value tax: it does not rise when you sell a more expensive version, and it takes a larger share of the price for cheaper versions.

A combined excise charges both a value component and a quantity component on the same product. Alcoholic drinks are the typical example, with a value component and a component linked to alcohol content. Some beverages carry a component linked to sugar content. Passenger cars use a value-based tax whose rate depends on characteristics such as emissions and powertrain type.

The practical lesson is that you cannot estimate excise from the customs value alone. You need the excise category, the current rate structure for that category, the base the law uses for your product, and the product data the structure depends on, such as alcohol content, sugar content or emissions. Collect that data before you ask for a calculation, and ask your broker or the Excise Department to confirm the structure for your exact product.

How does excise stack with duty, local tax and VAT?

At import, duty is calculated on the customs value, excise is calculated on its own base, a local tax for the Ministry of Interior is calculated by reference to the excise, and VAT is then charged on a base that adds the customs value, duty, excise, local tax and any other taxes collected at import; each layer increases the next.

The order matters because the taxes compound. Duty is the first layer and does not depend on excise. Excise is the second layer, with its own base and rate. Then come amounts calculated by reference to the excise. The best known is a local tax collected for the Ministry of Interior to fund local administration, which is charged as a share of the excise. For some goods, such as alcohol and tobacco, further levies earmarked for specific public funds are also collected with reference to the excise. The exact list depends on the product and on current law, so confirm it for your goods.

VAT is the last layer. For imports, the VAT base is broadly the customs value plus duty plus excise plus those other taxes and levies collected at import. Because excise sits inside the VAT base, a high excise also means higher VAT on the same shipment, even though the VAT rate itself has not changed.

This stacking is why importers of excisable goods sometimes find that the total tax at import is a multiple of the duty they expected. It also explains why the order and the base for each layer matter when you check a calculation. If a broker's estimate looks off, ask them to show each layer separately: value, duty, excise and its base, the local tax and any levies, then VAT and its base.

Our article on how import duty and VAT are calculated in Thailand sets out the duty and VAT steps in more detail, and the paying import duty and tax steps guide explains how the total is paid on the declaration.

Who files and pays excise when goods are imported?

The importer is liable, and for most imports the excise is declared and paid through the import declaration that the importer or its licensed customs broker files with Customs; for some goods the importer must also register with the Excise Department, notify prices, use excise stamps, hold licences and file regular reports.

On the customs side, the mechanics are familiar. The import declaration carries the tariff line, the value and the quantity, and the customs system calculates duty, excise, the local tax and VAT from the data declared. The importer pays the total through the usual payment channels, and the goods are released once payment and any inspection are complete. A broker who handles excisable goods regularly will know which extra data fields and attachments the excise calculation needs.

On the excise side, the obligations depend on the product. Importers of some excisable goods are expected to register with the Excise Department as operators. Those whose goods are taxed on a value base usually need to notify a suggested retail price before import. Alcohol and tobacco must carry excise stamps or other tax marks, which the importer arranges with the Excise Department, and selling those products in Thailand requires licences. Some importers of excisable goods also have reporting obligations for imported excisable goods, such as periodic reports of goods received and sold.

Because the requirements vary by product and change over time, we recommend a short call with the Excise Department or an experienced broker before the first shipment. Ask four questions: which excise category your product falls into, whether you need to register, what base and notification apply, and whether stamps, licences or reports apply. Write the answers down and keep them with your product file.

If you use a forwarder such as Thai Global Freight (TGF), it can coordinate booking, documents and the handoff to the customs broker so that excise data arrives with the shipment rather than after it.

What does the suggested retail price notification mean for importers?

For goods taxed on a value base, the Excise Tax Act uses the suggested retail price as the main base, so the importer generally notifies the Excise Department of the price at which the goods are expected to be sold to consumers before import, and that notified price, subject to the Department's review, drives the excise.

This is a change in mindset for importers who are used to thinking in terms of import cost. Duty is calculated on what you paid plus freight and insurance. Excise for these goods is calculated on what the consumer is expected to pay. Two importers bringing in the same product at the same cost could, in principle, face different excise if they intend to sell at different retail prices.

The notification has practical consequences. First, it needs to be ready before the goods arrive, because the excise calculation at import depends on it. Second, it should be consistent with how the goods are actually sold. The Excise Department can review notified prices and has powers to set the base where it considers the notified price inappropriate, for example where it is out of line with market prices. Third, if you change the retail price materially, you may need to notify a new price. Check the procedure and timing with the Department.

For importers, this also means pricing decisions and tax decisions are linked. When you set a retail price for an excisable product, you are also setting its excise base. Commercial teams and finance teams should agree the retail price before the notification is filed, and keep a record of how the price was set, so that the notification can be explained if the Department asks.

Not every excisable product uses this base. Goods taxed by quantity, such as fuel, or where the law prescribes another base, follow those rules instead. Confirm which applies to your product before you plan your pricing.

How does excise affect landed cost and pricing?

Excise is part of landed cost and, for a VAT-registered importer, it is normally a real cost that cannot be reclaimed as input tax, unlike import VAT; because it also raises the VAT base and the local tax, it should be modelled layer by layer before you set a selling price.

Landed cost is the total cost of getting goods to your door, ready to sell: purchase price, international freight and insurance, origin and destination charges, duty, excise and other taxes, broker fees and inland delivery. Our guides on what landed cost is and on Thailand import costs explained show how to build it. Excise belongs in the tax section of that build, alongside duty, and it often dominates that section for alcohol, cars and some beverages.

The distinction between recoverable and non-recoverable taxes matters for pricing. A VAT-registered business can usually claim import VAT as input tax against its output VAT, so import VAT is mostly a cash-flow item rather than a final cost. Excise and duty do not work that way; they are costs that have to be recovered through the selling price. A landed-cost model that treats all taxes the same will either overprice or underprice the product.

Cash flow is the other effect. Excise is paid at import, before the goods are sold, together with duty and VAT. For high-excise goods that can tie up a large amount of working capital per shipment. Importers sometimes use bonded or free-zone arrangements, where available and appropriate, to defer the point at which taxes become payable, which we cover in the next section.

Finally, excise interacts with your commercial choices. Because some categories are taxed by quantity or by product characteristics such as alcohol content, sugar content or emissions, a change in specification or pack size can change the excise. Model the options before you fix the product range.

Are there exemptions, suspensions or refunds for excise on imports?

Yes, in defined cases: goods that qualify for exemption from import duty may also be exempt from excise where the law links the two, excise can be suspended while goods stay in a bonded warehouse or free zone under the applicable rules, and refunds may be available for some exported or re-exported goods, but each case has conditions that must be confirmed.

The Excise Tax Act and its regulations provide that certain imports exempt from customs duty under customs law are also exempt from excise. Examples commonly cited include goods brought in under specific customs privileges such as diplomatic or similar status, and certain returned or temporary imports. The link is not universal, and it depends on the legal basis of the duty exemption. Confirm with the Excise Department or your broker whether a particular duty exemption also covers excise.

Suspension is different from exemption. Goods placed in a bonded warehouse or a free zone are generally not yet treated as imported into Thailand for tax purposes, so duty, excise and VAT are not collected while they stay there under the zone's rules. When goods leave the zone into the Thai market, the taxes become payable at that point. Our article on free zone versus bonded warehouse explains how these regimes work and what records they require.

Investment promotion is a separate question. Board of Investment privileges typically relate to import duty on machinery and raw materials. They do not automatically extend to excise, and excisable goods need specific confirmation. Our article on BOI import duty exemption and freight covers the duty side.

Refunds and credits exist for some situations, such as excisable goods that are exported, and for certain goods used as inputs in producing other excisable goods. The conditions, documents and timing are specific, so treat refunds as something to confirm in advance rather than to rely on afterwards.

What mistakes do importers make with excise tax?

The most common mistakes are assuming an FTA preference removes excise, estimating excise from the customs value, leaving excise out of landed cost, notifying a retail price that does not match real sales, and discovering stamp, licence or registration requirements only after the goods arrive.

The FTA mistake is the most expensive because it usually appears late. A buyer negotiates a supply contract on the basis that the goods will enter duty-free under an agreement, prices the product accordingly, and only discovers at the first import that excise, the local tax and the VAT on top of them still apply.

Estimating from the customs value is the second. For goods taxed on a notified retail price or by quantity, the customs value is not the base, so an estimate built on it can be well off. The same applies to using last year's rate, or a rate structure for a different variant of the product.

Leaving excise out of landed cost, or treating it like recoverable VAT, is the third. The product looks profitable on paper until the first tax bill arrives.

The fourth is a notified price that does not reflect the market. If the Excise Department considers the notified price inappropriate, it can set the base itself, and the importer may face additional tax for past imports as well as future ones.

The fifth is administrative. Alcohol and tobacco need stamps and licences, some importers need to register as operators, and some must file regular reports. Learning this when the container is already at the port leads to storage charges and delays. Our articles on controlled import goods in Thailand and on import permits explain the wider permit landscape.

A quieter sixth mistake is not keeping product data. Excise for many goods depends on alcohol content, sugar content or emissions data, and Customs or the Excise Department may ask for it. Keep the data with your product file and update it when the specification changes.

What should you prepare before importing excisable goods?

Before the first shipment, confirm the excise category and current structure for your product, settle any registration and price notification with the Excise Department, collect the product data the tax depends on, arrange stamps and licences where needed, and build excise, local tax and VAT into landed cost with your broker.

A short preparation sequence works for most products:

• Identify the excise category. Compare your product to the excise tariff and ask the Excise Department or your broker to confirm where it falls.
• Confirm the structure. Find out whether the tax is by value, by quantity or both, what base applies, and what product data it depends on.
• Register if required. Some importers of excisable goods must register as operators with the Excise Department before importing.
• Notify the retail price. For value-based goods, agree the suggested retail price internally and notify it in time for the first import.
• Prepare product data. Alcohol content, sugar content, emissions, engine or battery data, as relevant, with supporting test reports or certificates.
• Arrange stamps and licences. For alcohol and tobacco, plan excise stamps, labelling and sales licences before goods arrive.
• Model landed cost. Layer duty, excise, the local tax, any levies and VAT on the right bases, and separate recoverable VAT from non-recoverable taxes.
• Check reliefs. If you plan to use a bonded warehouse, free zone, duty exemption or export refund, confirm in writing that excise is covered and what records are needed.
• Brief your broker and forwarder. Share the excise data with the customs broker before the vessel or flight arrives so the declaration can be prepared without delay.

Once this is in place, repeat imports become routine: check that the product and price have not changed, confirm current rates, and file. Our first-time importer checklist places these steps within the wider preparation for any import into Thailand.
