US Tariff on Auto Parts from Mexico 2026

Auto parts from Mexico that qualify for USMCA (formerly NAFTA) treatment enter the US at 0%. Non-qualifying parts face the standard MFN rate (0–4% for most HTS 8708 subheadings) plus any applicable Section 232 tariff. The Section 232 proclamation (Presidential Proclamation 9739, 25% on autos/parts) has targeted application — confirm whether your specific part is covered.

Compliance risk notes

1Section 232 auto parts tariffs (Proclamation 9693) impose 25% on specified parts unless an exclusion is granted — the parts list is defined by HTS subheading, not broadly by Chapter 87.
2USMCA Regional Value Content (RVC) requirements are 62.5% for engines/transmissions and 60% for most other auto parts — parts with high Chinese content may not qualify.
3CBP origin verification audits for USMCA auto claims are common; ensure your supplier can provide a detailed bill of materials with value calculations.
4Steel and aluminum content in auto parts may trigger indirect Section 232 exposure even if the auto part itself is not on the Section 232 list.
5Executive action under IEEPA could impose additional tariffs on Mexican auto imports beyond Section 232 — monitor Federal Register for proclamations.

FAQ: What tariff rate applies to auto parts imported from Mexico?

Do I need a USMCA Certificate of Origin for every shipment?

You need a valid USMCA certification of origin (which can be a blanket certificate covering multiple shipments within a 12-month period). The importer, exporter, or producer can certify. Keep records for 5 years.

What is the tariff on aftermarket auto parts from Mexico that don't meet USMCA?

Non-qualifying aftermarket parts face the MFN rate, which is typically 2.5% for most HTS 8708 subheadings. However, if the part is on the Section 232 auto parts list, the rate becomes 25% regardless of USMCA status.

Are brake pads and filters from Mexico covered by Section 232?

Brake assemblies and certain filters were among the parts targeted in the Section 232 auto parts action. Check the specific Annex to Proclamation 9693 for your HTS subheading. Parts not listed in the Annex face only MFN rates (subject to USMCA preference).
