4. Products covered (HS or CCCN where applicable, otherwise national tariff 
heading. ICS numbers may be provided in addition, where applicable):  Hot-Rolled 
Flat Steel for Welded Structure  
5. Title, number of pages and language(s) of the notified document:  Draft Thai 
Industrial Standard for Hot -Rolled Flat Steel fo r Welded Structure (TIS 1499 -2563 (2020)) 
(22 page(s), in Thai)  
6. Description of content:  The Thai Industrial Standards Institute (TISI) has proposed to 
withdraw the Thai Standard for Hot -Rolled Carbon Steel Coil Strip Plate and Sheet for 
Welded Structur e (TIS 1499 -2541 (1998)) and replaced it with Hot -Rolled Flat Steel 
for Welded Structure (TIS 1499 -2563 (2020)) as a mandatory standard.  
This standard covers hot -rolled flat steel including unalloyed and alloy steels used for 
welded structures such as brid ges, ships, rolling stock, petroleum storage tanks, 
containers and other structures with especially high weldability.  
This standard excludes:  
1. Other hot -rolled flat steels regulated as a mandatory standard such as the hot rolled 
flat steel for general structure (TIS 1479 -2558 (2015)).  
2. The hot -rolled flat steel of applicable thickness over 200 mm.  
3. The subsequent rerolling flat steel excluding applied by skin pass, temper rolling or 
roll forming process.  
7. Objective and rationale, includin g the nature of urgent problems where
