🚨 Thailand Just Expanded 37.54% Tariff to Cover ZAM Coated Steel – Your GL & ZAM Orders Are at Risk

The trade walls against Chinese coated steel just got higher. On October 5, 2026, Thailand‘s Anti-Dumping and Countervailing Committee issued a final anti-circumvention ruling, expanding its existing anti-dumping duties on hot-dip galvanized cold-rolled steel coils to hot-dip galvanized aluminum-magnesium alloy (ZAM) cold-rolled steel coils.

The ruling targets the practice of circumventing existing anti-dumping duties by slightly modifying the coating composition – shifting from traditional galvanized to ZAM-coated products. Thailand has now closed this loophole.

And Thailand is not alone. The global trade wall against Chinese steel continues to rise:

 – On October 5, Commerce announced final results of the expedited fifth sunset reviews, keeping anti-dumping duties on Chinese cut-to-length carbon steel plate in place

 – Final anti-dumping and countervailing duties on Chinese flat-rolled steel, with rates of 9.4%–51.2% anti-dumping and 2.7%–3.9% countervailing, effective September 24

 – On October 1, the Global Forum on Steel Excess Capacity agreed on the Milwaukee Framework, where 28 market economies pledged to intensify anti-dumping and countervailing investigations against Chinese steel and share “melt and pour” data to close circumvention loopholes

 – The “Melt and Pour” origin rule took full effect on October 1, requiring importers to declare the country of first melting and casting, with Mill Test Certificates (MTC) as mandatory documentation

If you export galvanized (GI), galvalume (GL), or ZAM-coated steel to Thailand or other Southeast Asian markets, your cost structure is changing dramatically. Anti-circumvention rulings are closing the loopholes that once allowed alternative coated products to enter freely.
