HS Code Reference · Chapter 87 + Section 232
HS Codes for Auto Parts 2026
The 2.5% MFN rate is history for most parts: Section 232 adds 25% on engines, brakes, transmissions and electrical systems since 2025 — from nearly every origin. HTS codes, the S232 covered list, and USMCA carve-outs in one table.

MFN = Most Favored Nation rate. S232 = Section 232 national-security tariff (2025) — applies to most origins, with USMCA preferences. China-origin parts stack Section 301 on top; parts on the Section 232 list pay 25% (15% all-in from the EU, Japan, Korea and Taiwan) instead of the forced-labor tariff. Verify at hts.usitc.gov.
Section 232 changed the math for everyone — not just China
Unlike Section 301 (China-only), the 2025 Section 232 auto parts tariff applies to nearly every origin — Germany, Japan, Korea, Taiwan included. A German brake assembly that cost 2.5% in duty now carries 27.5%. The main relief is USMCA-qualified contentfrom Mexico and Canada, which demands regional-value-content documentation. If you import any powertrain, brake, suspension or electrical part, re-run your landed cost now.

Auto Parts Import Duty — FAQs
Most automotive parts classify under heading 8708 (parts and accessories for motor vehicles): brakes 8708.30, transmissions 8708.40, wheels 8708.70, suspension 8708.80. Engines are Chapter 84 (8407/8408), electrical parts like starters Chapter 85 (8511), tires Chapter 40 (4011). The 'parts of general use' rules push some items to other chapters.
The base MFN rate is low — typically 2.5%. But since 2025, Section 232 national-security tariffs add 25% on a broad list of imported auto parts (engines, transmissions, electrical components, brakes, suspension). USMCA-compliant parts from Mexico/Canada have preferential treatment. China-origin parts can also stack Section 301 — total burden can exceed 50%.
In 2025 the US imposed 25% tariffs on imported automobiles and key auto parts under Section 232 (national security). Covered parts include engines, transmissions, powertrain components, electrical systems and more. Unlike Section 301, S232 applies to most origins — not just China — with USMCA-compliant content from Mexico/Canada receiving special treatment. The covered-parts list can expand; verify your HTS code's current status.
Partially. USMCA-originating auto parts (meeting regional value content rules) receive preferential treatment under the Section 232 regime — the tariff applies only to non-US content in some configurations. Documentation is demanding: regional value content calculations, labor value content, and certification. Non-originating parts from Mexico pay the full S232 rate.
No — HS classification is based on what the part is, not who made it. A brake pad is 8708.30 whether OEM or aftermarket. What does differ: anti-dumping orders sometimes target specific origins (e.g. Chinese brake rotors), and IP enforcement (counterfeit parts seizures) is aggressive in the auto category.
The levers: (1) USMCA-qualify production in Mexico/Canada, (2) verify whether your specific part is actually on the S232 covered list — many accessories aren't, (3) check FTA eligibility for Korea (KORUS) and other origins, (4) correct classification — vehicle-specific vs universal parts can land in different chapters with different rates. Model each scenario in the calculator before committing to a sourcing plan.

HS code lookup is step one. Our calculator stacks MFN + Section 232 or the forced-labor tariff + Section 301 + MPF/HMF and freight for the true landed cost — per origin scenario.
