ATIGA in 2026: How to Cut Import Duties to 0% in Thailand

In 2026, foreign investors operating in Thailand are saving billions of dollars on imported raw materials and components from ASEAN countries. The mechanism behind this is ATIGA, the ASEAN Trade in Goods Agreement, which eliminates duties on nearly 99% of tariff lines within the bloc. If you are building a manufacturing or export business in Thailand, this is your single most powerful financial tool.

Thai companies have already claimed ATIGA preferences worth more than 33 billion USD over the past two years. Since 2025, the Second Protocol of ATIGA has been in force, bringing fully digital certificates of origin, streamlined procedures, and the removal of non-tariff barriers. For importers, this translates into predictable costs and a serious competitive edge over suppliers from China or India.

For investors also looking at the property side of Thailand, it is worth noting that the country's real estate rules are moving in a similarly foreigner-friendly direction: a new one-year visa scheme tied to property ownership has been confirmed in Phuket, available to buyers of condominiums worth at least 3 million THB, within the standard 49% foreign ownership cap per project.

Quick Answer

• ATIGA (ASEAN Trade in Goods Agreement) has been in force since 2010 and eliminates duties on 99% of goods traded within ASEAN, provided a Form D certificate of origin is presented

• Preferences claimed under ATIGA exceeded 33 billion USD in 2025-2026

• The Second Protocol of ATIGA (effective 2025) introduced digital certificates of origin and faster clearance

• The model of 'import raw materials under ATIGA, process, then export' allows 100% foreign ownership without Foreign Business Act restrictions

• Combining ATIGA with BOI incentives can deliver up to 8 years of tax holidays plus full duty exemption on raw materials and equipment

• Basing operations in the Eastern Economic Corridor (EEC) or border Special Economic Zones unlocks the maximum combined incentive package

Key Facts

• ATIGA is Thailand's core intra-ASEAN trade agreement, in force since 2010. It is not a theoretical framework but an operating mechanism that zeroes out import duties in practice

• To qualify for the zero rate, goods must meet Rules of Origin criteria, and the importer must present a Form D certificate. One incorrectly filed document can wipe out the entire savings

• Market participants report that 15-20% of initial ASEAN shipments require correction due to non-compliance with origin criteria, making supplier due diligence essential from day one

• Main ATIGA import categories include electronic components (Malaysia, Singapore, Vietnam), petroleum products and chemical feedstock (Malaysia, Indonesia), plastics, rubber, palm oil, and automotive parts

• Thailand exports back into ASEAN vehicles, air conditioners, electronics, rubber products, and processed agricultural goods

• Pure import for resale on Thailand's domestic market requires a Foreign Business License (FBL) or substantial registered capital under FBA List 3, which is why most successful foreign importers pursue a value-added, export-oriented model instead

• BOI incentives for export-oriented manufacturers include duty exemption on imported equipment, tax holidays of up to 8 years, and land ownership rights within industrial zones

How to Start: Step by Step

1. Define your business model. The key question: will you process imported raw materials and export the finished product, or sell domestically? The first path allows 100% foreign ownership without an FBL. The second requires licensing.

2. Vet suppliers against Rules of Origin. Before signing contracts, confirm that your suppliers in Malaysia, Vietnam, Indonesia, or Singapore can provide a valid Form D certificate. Without it, the duty exemption simply does not apply.

3. Choose a location with maximum incentives. The Eastern Economic Corridor (Chachoengsao, Chonburi, Rayong provinces) and border Special Economic Zones offer additional tax incentives layered on top of standard ATIGA preferences.

4. Apply to the BOI. Thailand's Board of Investment grants foreign manufacturers full duty exemption on raw materials and equipment, tax holidays, and land ownership rights. The process typically takes 2 to 4 months.

5. Register your company. A standard Thai company with foreign ownership is sufficient for export-oriented manufacturing. Minimum registered capital depends on the activity and BOI conditions.

6. Set up Form D documentation flows. The Second Protocol of ATIGA enables digital certificates of origin. Establish electronic exchange with Thai customs and your suppliers in advance.

7. Run a pilot shipment. Experience shows that the first 3-5 shipments often require documentation adjustments. Test the process on a small volume first.

8. Scale using regional supply chains. Once procedures are running smoothly, bring in suppliers from multiple ASEAN countries to diversify risk and optimize cost of goods.

If you are planning a trip to Thailand to inspect industrial zones in the EEC or meet potential suppliers, it is worth arranging flights and a multi-province itinerary well in advance.

FAQ

What is ATIGA and how does it work?

ATIGA (ASEAN Trade in Goods Agreement) is a trade agreement among the 10 ASEAN member states that eliminates or sharply reduces import duties on goods manufactured within the bloc. To qualify for the preferential rate, the product's origin must be verified with a Form D certificate.

Can a foreigner own 100% of an import business in Thailand?

Yes, if the business model follows the 'import raw materials, process, export' structure. This activity falls outside the restrictive lists of the Foreign Business Act. Pure import for domestic resale requires a Foreign Business License.

What is Form D and why does it matter so much?

Form D is the certificate of origin under ATIGA. Without it, Thai customs will apply the standard duty rate instead of zero. Since 2025, this document has been available in digital format.

What goods are most commonly imported under ATIGA?

Electronic components and microchips from Malaysia and Singapore, petroleum products and chemical feedstock from Malaysia and Indonesia, plastics, rubber, palm oil, automotive parts, and industrial equipment.

What does the BOI offer foreign manufacturers?

Thailand's Board of Investment grants full exemption from import duties on raw materials and equipment, tax holidays of up to 8 years, land ownership rights in industrial zones, and permission to bring in foreign specialists.

Why is the Eastern Economic Corridor better than other regions?

The EEC (Chachoengsao, Chonburi, Rayong provinces) offers the maximum combined incentive package: ATIGA preferences, enhanced BOI incentives, and additional tax relief for high-tech manufacturing.

What percentage of shipments need correction at the start?

Market estimates put this at 15-20% of initial ASEAN shipments, which need documentation corrections related to origin rules. This is precisely why supplier vetting before signing contracts is critical.

Can ATIGA be used for re-export?

Yes. A company can purchase goods within ASEAN at zero ATIGA duty and re-export them to Europe, the US, or Australia. This structure also permits 100% foreign ownership without an FBL.

What is the difference between ATIGA and Thailand's standard duties?

Thailand's standard import duties from non-ASEAN countries can reach 20-30% depending on the product category. ATIGA reduces the rate to 0% for 99% of tariff lines when origin rules are met. The difference in cost of goods is substantial.

ATIGA is far more than a way to save on duties. It is a strategic advantage that lets foreign entrepreneurs plug directly into Southeast Asia's most powerful manufacturing supply chains. The keys to success are the right business model (import, process, export), correct Form D documentation, and choosing the optimal location for maximum incentives.
