Auto parts manufacturing in China

China leads; alternatives compete. China supplied 10.4% of US HS 8708 parts imports in 2025 against Mexico's 41.6% (UN Comtrade), third behind Mexico and Canada.

Is China still the default source for auto parts?

China leads outside North America, but it is not the default source for the US market. Auto parts are the components and accessories of motor vehicles; the narrowest trade definition is HS heading 8708 (parts and accessories of motor vehicles), and broader definitions add engines, tires, glass, lighting and electrical parts. On either measure China ranks third among suppliers of US auto-parts imports, behind Mexico and Canada, and its share is falling.

The USITC figure comes from its 2025 USMCA automotive report (Pub. 5642, Table 2.5), which uses a broad vehicle-parts HTS list; in 2024 that list shows Mexico $81.2B, Canada $19.5B, China $18.3B, Japan $15.8B and South Korea $12.7B. The HS 8708 figures are US-reported UN Comtrade data queried October 30, 2026, and 2025 values may be revised. The two are not comparable, and a third source, Mexico's National Auto Parts Industry association (INA), as reported in the press, puts China at 6.6% of US auto-parts imports in 2025 (7.6% in 2024) under an unstated definition. Any "China share" for auto parts should name its scope.

China's role elsewhere is growing. China's worldwide auto-parts exports reached $95.11B in 2025, up 2.4%, according to the China Association of Automobile Manufacturers (CAAM) from customs data, as reported by Gasgoo in May 2026. China-reported HS 8708 exports to the US fell from $11.54B in 2024 to $10.34B in 2025, while its HS 8708 exports to the world rose from $56.64B to $59.05B. Volume is being redirected to other markets rather than lost.

Where auto parts are made, and how production is organized

Auto-parts production in China is often described in trade literature by provincial cluster, but no government or academic source for specific city specializations was found in the research for this page, so none is mapped here. A buyer should confirm where a part is actually made from the supplier's business license and production address, not from a regional reputation.

Production splits along tooling. Stamped, cast, forged and injection-molded parts need dedicated dies or molds, which the buyer often pays for and should own in writing; the MOQ (minimum order quantity) then reflects a production run long enough to justify setup. Catalog aftermarket parts such as filters, brake pads and lamps often run on existing tooling, so their MOQs are lower and are set mainly by packaging and branding.

Lead time is driven by tooling build, first-article approval for original-equipment (OE) programs, often run on the PPAP model (Production Part Approval Process — a documented sign-off that the production process makes conforming parts), material sourcing and ocean transit. IATF 16949 is the automotive quality-management standard buyers ask for; a certificate shows the factory runs that system, not that a given part conforms.

US compliance: FMVSS, EPA and the connected-vehicle rule

Safety standards

Some aftermarket equipment is regulated directly by a Federal Motor Vehicle Safety Standard (FMVSS) under 49 CFR Part 571, for example lighting (FMVSS 108), brake hoses (106), brake fluid (116), glazing (205), seat belt assemblies (209), child restraints (213), motorcycle helmets (218) and tires. The manufacturer self-certifies; NHTSA does not pre-approve parts. Most mechanical parts, such as filters, pads and suspension components, have no FMVSS. Foreign manufacturers of FMVSS-covered equipment must designate a US agent for service of process (49 CFR 551.45) and file manufacturer identification (Part 566); tire makers need a NHTSA-assigned plant code for the DOT Tire Identification Number (Part 574); recalls run under Part 573. These section numbers were not re-read against eCFR for this page and should be confirmed before relying on them.

Emissions

The Clean Air Act prohibits selling or installing defeat devices — parts that bypass or disable a vehicle's emission controls. Aftermarket catalytic converters must meet EPA requirements, and California requires a CARB Executive Order for many emissions-related parts.

Connected vehicles

The Bureau of Industry and Security (BIS) final rule of January 16, 2025 (90 FR 5360, effective March 17, 2025, codified at 15 CFR 791.300 et seq.) bars importing or selling connected passenger vehicles and Vehicle Connectivity System hardware with a sufficient nexus to China (including Hong Kong and Macau) or Russia. A Vehicle Connectivity System (VCS) is hardware or software that enables radio-frequency communication above 450 MHz, such as Bluetooth, cellular, satellite or Wi-Fi. VCS and Automated Driving System software prohibitions begin with Model Year 2027; VCS hardware prohibitions begin with Model Year 2030, or January 1, 2029 for hardware without a model year (BIS). VCS hardware importers must file Declarations of Conformity through BIS's portal, conduct due diligence and keep records for 10 years. The rule covers passenger vehicles under 10,001 lb only; BIS said a separate commercial-vehicle rule would follow, and whether it has been issued by October 2026 is unconfirmed.

Tariffs on Chinese auto parts, as of October 2026

Proclamation 10908 of March 26, 2025 set the 25% Section 232 duty on automobiles from April 3, 2025 and on covered parts from May 3, 2025. No drawback is allowed, and covered parts admitted to a foreign-trade zone must take privileged foreign status. Heading 9903.94.06 carries 0% for USMCA-eligible parts and for articles not used in passenger vehicles or light trucks. The proclamation has been amended since, including Proclamation 10925's offset framework and country deals; CRS records the autos and parts rate as "15%–25%, varies by product and country," but no deal covers China, so covered Chinese parts pay 25%.

The covered list grows. Commerce runs an inclusions process in which domestic producers can ask to add parts during two-week windows in January, April, July and October; an April 1–14, 2026 window was announced. A part that was outside Section 232 in 2025 may be covered now.

Section 301 list duties apply on top of the 232 duty. The 12.5% forced-labor Section 301 duty, effective July 24, 2026, does not apply to Section 232 goods, including passenger-vehicle and light-truck parts (HTSUS Chapter 99 note 52), so a Chinese auto part outside the 232 list may carry that 12.5% instead. A court challenge to the forced-labor duty has been reported. Antidumping and countervailing duty orders, such as those that have covered certain Chinese tires, apply in addition; the current list of orders on automotive products was not checked for this page. IEEPA tariffs ended after the Supreme Court's February 20, 2026 ruling. A licensed customs broker should confirm the classification and stack for each part.

Where auto-parts production is shifting, and why

For the US market, the shift is to Mexico. Mexico's share of US HS 8708 imports rose from 40.5% in 2024 to 41.6% in 2025, while China's fell from 11.3% in 2023 to 10.4% in 2025 (UN Comtrade). USMCA treatment, which can bring the Section 232 rate to 0% for eligible parts, depends on qualifying origin under the agreement's rules, not on the shipping route.

Chinese content still reaches the US indirectly. USTR's 2026 USMCA Autos Report to Congress (July 1, 2026) found that China's share of value-added content in Mexico's transport-equipment imports rose from 4.5% in 2017 to 7.1% in 2024, and in Canada from 3.3% to 4.2%. That is a value-added measure, not a direct import share, but it shows that the decline in direct US imports from China overstates the decline in Chinese content.

Common mistakes, and how to evaluate an auto-parts supplier

• Assuming an aftermarket part is outside Section 232. The test is the HTS line on the automobile parts list and use in passenger vehicles or light trucks, not the sales channel.
• Missing new inclusions. The parts list expands after each quarterly window.
• Forgetting Section 301. List duties still apply on top of the 25% 232 duty for Chinese parts.
• Claiming USMCA 0% for a Chinese part routed through Mexico. Transit does not confer origin.
• Buying telematics, infotainment, cellular or Wi-Fi modules without checking the connected-vehicle rule. Software dates start at Model Year 2027 and hardware dates at 2029 or Model Year 2030.
• Importing FMVSS-covered equipment without the paperwork. Lamps, tires, brake hoses and helmets need certification, markings and a designated US agent.
• Importing "performance" exhaust or tuning parts that are defeat devices. They are illegal to sell or install under the Clean Air Act.
• Paying for molds and dies without a written tooling-ownership clause.

An auto-parts supplier is evaluated against the rule that governs the specific part. For FMVSS-covered equipment, ask for the test reports behind the self-certification and confirm the manufacturer's US agent designation and identification filings. For emissions-related parts, ask for the EPA and CARB documentation. For any part with radio connectivity, ask for the information BIS requires in a Declaration of Conformity. For OE-style programs, ask for the IATF 16949 certificate and its scope, and agree first-article approval and tooling ownership in the contract before tooling is cut.
