Key Takeaways
- Legal Importer Requirement: A Thai-registered juristic person must act as the applicant and license holder for TISI import licenses.
- Two Pillars of Mandatory TISI Licensing: 1) Quality management assessment of the foreign manufacturing plant, and 2) Product sample testing (TISI Testing) at a TISI-approved laboratory.
- TISI-NSW Customs Linkage: Transmits electronic permit numbers or exemption confirmations directly to the Thai Customs e-Customs system.
1. TISI e-License vs. TISI-NSW Explained
- TISI e-License: Manages mandatory standard import licenses (Form Mor.Or.Kor. 20), factory registration records, and mandatory TISI mark QR codes.
- TISI-NSW: Handles per-invoice shipment notifications, temporary clearance of product samples for laboratory testing, and scope determination requests.
2. TISI Testing & Quality Control Assessment Requirements
For products subject to mandatory Thai Industrial Standards (such as regulated steel products, electrical appliances, tires, or automotive safety glass under TISI 196), obtaining an import license involves:
- Manufacturing Quality System Assessment: Conducted through factory inspection or evaluation of accepted quality management certificates in accordance with TISI's Particular Requirements for each standard.
- Product Sample Testing (TISI Testing): Samples are imported via a TISI-NSW sample permit and tested at a designated laboratory accredited or recognized by TISI.

When imported industrial items (such as standard bolts, screws, and fasteners under HS 7318 or specialized machinery spares) share a tariff heading with regulated steel or electrical standards but fall outside the mandatory technical scope, importers can submit engineering drawings and product specifications via TISI-NSW to obtain an official out-of-scope confirmation for customs release.

Frequently Asked Questions

Q:What is TISI Testing?
A:TISI Testing refers to mandatory conformity testing of product samples conducted at a laboratory accredited or recognized by the Thai Industrial Standards Institute before a TISI license is granted.
Q:What if an HS Code triggers a TISI alert for non-regulated industrial parts?
A:If the physical product specifications fall outside the mandatory TISI royal decree scope, the importer can submit technical drawings and catalogs via TISI-NSW to obtain an out-of-scope exemption confirmation for customs release.
