SIAM NISTRANS สยามนิสทรานส์ : หน้าหลัก

The world of logistics and international trade has been rapidly changing, especially in the area of customs procedures and customs clearance. (Customs Duty / Tariff) plays a crucial role in the import/export process because it directly affects “the cost of goods”. Knowing the correct HS Code and customs requirements for each type of product can help reduce problems with goods being held at the port, delays in delivery, or cost changes.

That is why importers/exporters must stay updated and understand the changes in 2026 to ensure compliance and smooth operations. Using Siam Nistrans services will help ensure the highest level of safety and cost control throughout the customs process.

What is HS Code and how often is it updated?

HS Code is a universal classification code used in customs procedures under the Harmonized System (HS Code), helping customs officers worldwide determine details such as product type, clothing, food, etc., making customs procedures consistent across countries.

Thailand currently uses “HS 2022 / AHTN (specific to ASEAN)” to determine tariff rates and regulatory measures for controlled products, and this version has been officially applied since 2022.
HS Code has a direct impact on “Import Duty Rate” and required documentation for customs clearance.

Key updates 2024–2026 that businesses should be aware of

Implementation of electronic customs (e-Customs / NSW) as a standard

From 2025 onward, the Customs Department will enforce electronic authorization systems. Required documentation for import/export must go through a single system such as the NSW (National Single Window), to streamline approvals for each product-related agency.

Faster processing when exporting/importing
Reduces the chance of documentation errors

Control of regulated goods by other relevant agencies

Starting in 2025, certain product categories previously cleared easily must obtain additional permits/certifications. Examples include health products, industrial chemicals requiring approval, cosmetics, food supplements, and more.

Controlled status must be verified
Delays may happen if approval is not completed

Customs duties and changes according to HS and product category

Customs duty rates in Thailand range from 0–80% depending on the HS Code and Free Trade Agreement (FTA) eligibility. When correct HS Code is identified, duties for import/export can be planned before shipment.
