🚨 Mexico Just Imposed Up to $309/ton Tariff on Chinese HRC – Your Hot Rolled Steel Orders Just Got More Expensive

The trade walls against Chinese steel keep rising. On September 3, 2026, Mexico‘s Ministry of Economy issued a final affirmative anti-dumping ruling on hot-rolled steel (HRC) originating from China and Vietnam, officially imposing anti-dumping duties effective from the day after the announcement.

The products covered include hot-rolled flat-rolled products made of iron, carbon steel, or alloy steel – whether or not pickled, uncoated, with a thickness not exceeding 25.4mm and any width. This covers a vast range of hot-rolled steel products used across construction, manufacturing, automotive, and energy sectors.

Hot-rolled steel is the base material for downstream products like cold-rolled steel (CR), galvanized steel (GI), galvalume (GL), and pre-painted steel (PPGI). Every time a tariff hits HRC, it sends cost ripples through the entire steel supply chain.

And Mexico is not alone. The global tariff assault on Chinese steel continues to accelerate:

 – New safeguard rules effective July 1 cut quotas by 47% and raised over-quota tariffs to 50%, with the “Melt and Pour” origin rule set for full enforcement on October 1

 – Final anti-dumping duties of 23.1%–27.8% on Chinese HRC effective July 6

 – Provisional anti-dumping duties of 50.1%–55.3% on Chinese hot-dip galvanized steel (effective through December 7)

 – Final anti-dumping duties of 28.16%–33.10% on Chinese hot-rolled plates and coils

 – Both anti-dumping and safeguard investigations on cold-rolled flat products launched in July

 – Expanded high-carbon wire rod duties to 15.04%–36.79%

If you source hot-rolled, cold-rolled, galvanized, or pre-painted steel from China, your cost structure is changing by the week. Tariffs are accumulating, markets are closing, and the window to lock in current pricing is closing fast.
