Mexico's Chemical Market to Reach USD 71.24 Billion by 2033 as a 50% Tariff Reroutes Supply Without Replacing It — Pheonix Research

Mexico City, 23 October 2026 — Mexico’s chemical market will reach US$71.24 billion by 2033 from US$48.73 billion in 2025, a 4.86% CAGR on volume growth of 2.28% to 52,609 thousand tonnes, according to a new report from Pheonix Research. The tariff package that took effect on 1 January 2026 is changing the route and the price of the country’s chemical supply long before it changes the source.

The decree places 1,463 tariff fractions under duties of 5% to 50%, applied on the origin of goods rather than on the product, and covers an import flow the legislative record puts at US$51,910m — 8.3% of everything Mexico imported in 2024. Within the package, 316 fractions were left duty-free, 341 carry a 35% rate and 302 carry 10%; the 50% ceiling is concentrated on the highest-impact lines, light vehicles chief among them.

The first post-tariff semester did not show a market losing supply

It showed one paying more for it. Chemical imports reached US$21,443.2m in January–June 2026 against US$19,017.9m a year earlier, up 12.75%, while exports rose 7.79% to US$5,299.3m and the chemical trade deficit widened 14.48% to US$16,143.9m. Half a year of imports already equals 56.22% of the whole of 2025. Domestic chemical production fell 3.9% over the same period and domestic sales fell 1.3%.

The decree did work on the flows it could reach. Imports of the 1,463 covered fractions from non-treaty countries fell 23.24% between January and May, from US$15,383m to US$11,808m, and Chinese-origin imports of those lines fell 28.43%, from US$10,099m to US$7,228m. Taiwan-origin covered imports fell 32.7%, non-preferential Brazil 29.6%, South Korea 21.9%.

Inside the aggregate, a 4.11x gap measures the absence of domestic capacity

Autoparts imports from covered origins fell 39.5%, light vehicles 29.7%, footwear 37.9% and trailers 54.5%. Plastics imports fell 9.6%. The tariff cut autopart imports 4.11 times harder than plastics imports — and the difference is not enforcement, it is whether a domestic alternative exists.

The reach of the regime is also narrower than its headline rate implies. Because the decree operates on origin, goods from countries with a trade agreement retain preferential treatment: 69.6% of Mexico’s chemical imports arrive from North America at treaty rates, with a further US$1,669.2m from the European Union. Asia supplies 18.74% — the pool the decree can actually tax. Applied across that roughly US$7.15bn base, an effective 25% duty would add about US$1.79bn a year, equal to 3.67% of apparent consumption. That is an upper bound, not a forecast.

The binding constraint sits upstream of the border

Mexico imported 78.26% of the chemicals it consumed in 2025 by value and 75.58% by volume, running a US$28.16bn chemical trade deficit. Petrochemical installed capacity fell 35.9% year on year in ANIQ’s June 2026 reading, around 30% of sector capacity sits idle, and utilisation stood at 62.61% in October 2025. The domestic industry is not short of assets; it is short of the feedstock and economics that would let the assets run.

Pemex’s recovery programme commits MXN 93bn between 2026 and 2030 to reach 849,000 tonnes a year of petrochemical output and more than 4 million tonnes of fertilisers. Against a 2025 import volume of 33,198 thousand tonnes, that petrochemical target is 2.56% of the imported base. The Etano-Etileno project commits MXN 30bn to rehabilitate five plants at the Cangrejera and Morelos complexes, targeting 520,000 tonnes a year and lifting ethylene derivatives available for sale from those two complexes from 176,000 tonnes in 2025 to 1.029 million tonnes from 2030 — the single largest prospective change in Mexican chemical supply in a generation, and conditional on the works being executed and fed.

Three variables decide the 2033 number

Pheonix models three paths. In the substitution case (3.40% CAGR, US$63.68bn by 2033) the Cangrejera and Morelos restarts, Topolobampo ammonia and the fertiliser rehabilitations land close to schedule and import dependence falls. In the base case (4.86%, US$71.24bn) the current mix persists. In the import-dependence case (6.20%, US$78.85bn) projects slip and the import bill keeps compounding. The higher nominal number is the worse outcome for the country: in this market, value growth and industrial development point in opposite directions.

What separates them is feedstock, treaty and administration. First, a contracted, competitively priced ethane and gas supply for Cangrejera and Morelos — without it, rehabilitation produces nameplate capacity rather than supply. Second, the T-MEC review that opened on 1 June 2026, where ANIQ, Canada’s CIAC and the American Chemistry Council have jointly argued for preserving duty-free trade and making full use of the Chemical Sectoral Annex; a tightening of origin verification without a workable annex would expose the 69.6% of imports that currently arrive duty-free. Third, the fourth transitory article added by the Chamber of Deputies on 9 December 2025, which allows the Secretaría de Economía to open specific import mechanisms for non-treaty goods “with the objective of guaranteeing the supply of inputs in Mexico under competitive conditions.” Any company modelling 2027 chemical costs should read that clause as the live policy lever.
