Pheonix Research Sizes Mexico Tool Steel Imports at USD 142.8 Million and Finds No Tool-Grade Line Carries the 50 Per Cent Duty

MEXICO CITY, 24 October 2026 – Mexico’s December 2025 steel tariff, the largest single tariff action the country has taken in decades, does not reach tool steel at the rate it has been reported to. Read line by line off the 2026 Chapter 72 schedule, every tool-grade long product carries a duty of 35 per cent. The 50 per cent rate sits on commodity flat and wire rod. Pheonix Research sizes the Mexican tool steel import market at USD 142.8 million in 2025, rising to USD 203.0 million in 2033 at 4.5 per cent.

The Senate approved duties of up to 50 per cent on 10 December 2025 by 76 votes to 5 with 35 abstentions. The decree ran in the Diario Oficial on 29 December and took effect on 1 January 2026, covering 1,463 tariff lines, most at 25 or 35 per cent and a minority at the full 50, aimed at China, India, South Korea, Thailand and Indonesia.

The 50 per cent is real. It is on a different product.

Line 7228.30.01, which carries hot-finished bars of tool-grade steel, is dutiable at 35 per cent. So are the forged, cold-finished and other tool-grade bar lines, high-speed steel wire rod, tool-grade wire under NICO 01, and hollow drill bars. The 50 per cent rate applies to cold-reduced flat between 0.5 and 1.0 mm and to commodity wire rod: the products Mexican mills already make in volume.

Mexico has no tool steel mill. It imports more than 90 per cent of the moulds and dies it uses, and it imports the steel those moulds are cut from. Finished moulds and dies enter Mexico at zero duty.

A tariff that taxes the input above the output

Jorge Ayala of the AMMMT, the Mexican mould and die association, identified the inversion in September 2025, three months before the decree: finished moulds enter Mexico without paying tariffs while the steel to make them faces 20 per cent. The reform widened the gap, lifting tool-grade bar to 35 per cent and leaving the finished tool at zero.

Mexico is the second-largest importer of moulds and dies in the world, with consumption calculated at USD 5.0 to 6.0 billion. In 2024 it imported USD 1.72 billion of injection moulds, up 20.6 per cent, and USD 1.052 billion of dies, up 55.1 per cent, a combined USD 2.77 billion of finished tooling against USD 142.8 million of tool-grade steel beneath it. The AMMMT counts more than 300 tool shops in Mexico and considers 1,000 feasible; INA, the national industry association, puts an import-substitution programme at USD 7.0 to 9.0 billion over five to ten years.

The duty reaches about a sixth of the trade

Of the 2024 alloy bar flow, the United States supplied 43.0 per cent and Canada 29.5 per cent, so 72.5 per cent was North American and moves under the USMCA, untouched by the new schedule. Japan and Germany, at 5.8 and 5.4 per cent, enter preferentially. China, the target of the reform, is 8.2 per cent.

Applied to a 16 per cent dutiable slice of a USD 142.8 million market, a 35 per cent duty is worth about USD 8.0 million a year, rising to USD 11.4 million at 50 per cent. Pheonix Research’s assessment is that this is small enough to be absorbed at the border, passed through to the customer, or designed out by importing the finished mould instead.

Sizing the market under the basket

HS 7228.30 is an alloy bar basket, carrying 4140, 4340 and 8620 alongside tool grades, and stood at USD 571.0 million in 2025. At a 25 per cent tool-grade share, the tool steel import market is USD 142.8 million. Pheonix Research publishes the sensitivity with the figure: USD 114.2 million at a 20 per cent share, USD 171.3 million at 30 per cent. Against a global tool steel market of USD 4,906.0 million, Mexico is 2.9 per cent, falling to 2.7 per cent by 2033.

The three-case band runs from USD 180.8 million at 3.0 per cent to USD 227.5 million at 6.0 per cent, a spread of 1.26 times. The base case of 4.5 per cent reflects a market growing in the high single digits that is being partly met by something other than imports.

Falsifiers

Two developments would overturn the assessment. If the Diario Oficial adds 7228.30.01 to the 50 per cent list, the premise that tool grades were left at 35 collapses. If reported 7228.30 volumes fall by more than 15 per cent in 2027 while mould and die imports continue to grow, substitution is working and the forecast is too low rather than too high.
