Mexico Sets Provisional AD Duties On Hollow Aluminum Profiles

The Ministry of Economy has issued a preliminary resolution in its antidumping investigation into imports of hollow aluminum profiles originating in the United States and China, regardless of the country from which the goods are shipped. The resolution was published in the Official Gazette of the Federation (DOF) on Dec. 31, 2025, and stems from a complaint filed by Cuprum and Indalum. 

The investigation covers hollow aluminum profiles, alloyed or non-alloyed, in any size or shape, finished (for example painted or anodized) or unfinished. These are typically used in architectural applications like windows and doors. Imports generally enter under tariff code 7604.21.01 (NICO 00).

The ministry preliminarily excluded certain products used in automotive and thermal-management applications, including microchannel aluminum extrusions, flat tubes (MPE), profiles with zinc coating, profiles with tempering heat treatment, and hollow profiles made with series 3000 aluminum used in those industries.

Separately from the antidumping case, Mexico already applies a temporary 25% import tariff to goods entering under 7604.21.01, in force since April 23, 2024, with a two-year duration, while still allowing preferential tariff treatment for qualifying origin under trade agreements.

In the preliminary stage, the Ministry found positive dumping margins for both countries, calculating margins of 18.47% for the United States and 152.24% for China.

On injury, the Ministry observed price undercutting versus domestic products, including 13% (United States) and 31% (China) in the investigation period, alongside signs of market displacement. It also reported deterioration in key financial indicators for the domestic industry, including a 26% drop in domestic sales revenues over the analysis period and a decline in operating margin from 11.2% to 4.2%. 

As a provisional measure, Mexico set cash-deposit style antidumping duties of:

• US$1.62/kg for imports originating in the United States

• US$1.88/kg for imports originating in China

These provisional duties apply to definitive and temporary imports, regardless of the country of shipment, and will be in force for four months from the resolution’s entry into effect. The resolution enters into force the day after publication in the DOF, meaning Jan. 1, 2026. 

The investigation continues so interested parties can still participate. They can request a public hearing and submit arguments and additional evidence within the deadlines set in the resolution.

Earlier this week, Mexico’s federal government issued a decree reforming the General Import and Export Tax Law, establishing new tariff rates for a broad range of industrial and consumer goods, reports MBN. The move comes as Mexico seeks to regulate imports from nations with which it lacks standing trade agreements, a category that encompasses major Asian economies, including China. The decree, which entered into force on Jan. 1, impacts sectors ranging from steel and automotive to textiles and toys. 

A significant portion of the decree targets metal imports. Aluminum imports, including bars, profiles, and construction materials like doors and windows, are subject to duties ranging from 10% to 35%.
