FOR AUTOMOTIVE & PARTS IMPORTERS
Automotive parts importers: cut duty exposure and recover overpaid tariffs
The 2026 stack for vehicles and parts is dominated by a 25% Section 232 tariff that suppresses other layers and reshapes every recovery decision. We help you classify correctly, model the full stack, and pursue the refunds that are actually recoverable.
Most imported auto parts carry a ~2.5% base MFN rate plus a 25% Section 232 auto-parts tariff (HTS 9903.94.05), effective May 3, 2025; USMCA-qualifying parts are currently 0% (9903.94.06). The auto-parts 232 tariff has primacy — it suppresses Section 232 steel/aluminum/copper and IEEPA duties on the same article, but base MFN, Section 301 China, and AD/CVD still stack. Section 232 duties are not drawback-eligible; Section 301 is. All rates as of July 2026 — verify current status before filing.
The 2026 duty stack
What automotive & parts importers actually pay
As of July 2026, an imported auto part rarely pays one rate. It pays a stack, and the order of that stack — which layers apply and which are suppressed — determines your real landed cost. Every perishable rate below carries its effective date; verify current status before you file.
Base MFN (most-favored-nation) duty
Most heading 8708 parts carry ~2.5% base MFN; passenger vehicles (8703) are 2.5% and cargo vans / light trucks (8704) carry the 25% 'chicken tax' as their base rate. Base MFN applies underneath every trade-remedy layer. Source: USITC HTS Chapter 87.
Section 232 — automobiles & auto parts (25%, has primacy)
A 25% ad valorem tariff on covered automobiles (effective April 3, 2025) and covered auto parts (effective May 3, 2025) under Proclamation 10908. Parts fall under HTS 9903.94.05; USMCA-qualifying parts are currently 0% under 9903.94.06. This tariff has stacking primacy — an article subject to it is not also subject to Section 232 steel/aluminum/copper or IEEPA duties. Verify current status.
Section 232 — steel / aluminum / copper derivative (25% or 50%)
Effective April 6, 2026, metals-232 applies to the FULL customs value of a covered article (no longer just the metal content): 25% for derivative articles substantially made of the metal (over 15% by weight) and 50% for articles almost entirely of steel/aluminum/copper. Articles under 15% metal by weight are excluded. This layer is suppressed on parts already covered by the auto-parts 232 tariff. Source: CBP CSMS #68253075.
Section 301 — China (25% or 7.5%, stacks)
China-origin auto parts mostly fall on List 3 (+25%); some on List 4A (+7.5%). Section 301 stacks on top of MFN and Section 232. Active exclusions and rate suspensions run through November 10, 2026 following the November 1, 2025 U.S.-China agreement. Unlike Section 232, Section 301 duties are drawback-eligible. Verify current status.
IEEPA (reciprocal / Canada-Mexico) — generally not applicable here
Autos and auto parts covered by Section 232 are excluded from IEEPA reciprocal duties (heading 9903.01.33) and from IEEPA Canada/Mexico duties, because Section 232 takes precedence. IEEPA tariffs paid in 2025 are separately under a 2026 Supreme Court challenge and carry a refund posture. Source: CBP IEEPA FAQ; anti-stacking EO (April 29, 2025).
Antidumping / countervailing duties (AD/CVD)
Case-specific AD/CVD orders (e.g., on certain passenger and light-truck tires, wheels, and bearings from named countries) stack on top of every other layer at rates set per order. Check whether your specific part and origin are named in an active order.
MPF + HMF (user fees, FY2026)
Merchandise Processing Fee is 0.3464% of entered value per formal entry (minimum $33.58, maximum $651.50). Harbor Maintenance Fee is 0.125% of value on ocean shipments only. Both are recoverable via drawback on qualifying exports. Source: CBP User Fee table (January 22, 2026); 19 CFR 24.24.
Worked example. A $100 China-origin brake rotor (8708, List 3) lands at roughly 52.5% as of July 2026: 2.5% base MFN + 25% Section 301 (List 3) + 25% Section 232 auto parts. Because the auto-parts 232 tariff has primacy, no additional metals-232 layer applies on top — the same rotor coded to its steel line instead could trip metals-232 at up to 50%. The coding decision, not the paperwork, is where the money is. Verify current rates before filing.
Recovery
How automotive & parts importers get duty back
Recovery in this vertical is real but narrower than the headlines suggest — because the dominant 25% Section 232 layer behaves differently from the tariffs importers are used to recovering. We lead with the honest boundary on every lever. We are a builder, not a broker: we estimate, model, and (for IEEPA) file refund packages, but we never act as your Importer of Record or file customs entries.
Duty drawback (manufacturing / substitution) — for exported vehicles and parts
If you import components, build them into vehicles or parts in the U.S., and export the finished goods, you may recover up to 99% of eligible duties, taxes, and fees. The critical boundary: Section 232 duties are NOT drawback-eligible, so the dominant 25% auto-parts layer is not recoverable — but Section 301, base MFN, and MPF/HMF are. We estimate your recoverable amount and file through a partner drawback service provider; we never guarantee a refund figure or CBP acceptance. Source: CBP drawback trade-remedy FAQ.
USMCA rules of origin — qualify to 0% on parts
Auto parts that qualify under USMCA are currently 0% under HTS 9903.94.06, and USMCA vehicles have Section 232 applied only to non-U.S. content. Qualification is demanding: 75% regional value content, 40% (cars) or 45% (trucks) labor-value content above the wage threshold, and 70% North American steel and aluminum sourcing, plus core-parts rules. We model your bill of materials against these thresholds so you claim only what you can defend. Source: USTR USMCA Autos fact sheet; CRS IF12082.
HTS 9802.00.80 — U.S. components assembled abroad
When U.S.-origin components are shipped abroad, assembled, and returned, duty is assessed on the full value minus the value of those qualifying U.S. components — common for cross-border harness and sub-assembly work. The U.S. parts must be exported ready-to-assemble and not advanced in value abroad except by assembly. Whether the U.S.-content deduction flows through to the Section 232 base is fact-specific; we treat it as base-duty relief unless confirmed for your program. Source: CBP 9802 assembly guide; 19 CFR 10 Subpart A.
First Sale valuation — lower the base every layer applies to
In a multi-tier supply chain, First Sale lets you declare the earlier bona-fide factory sale rather than the marked-up middleman price, shrinking the customs value that MFN, Section 232, and Section 301 are all calculated on. As of July 2026 this is available, but the proposed Last Sale Valuation Act would eliminate it — monitor the legislative status. We help you assess eligibility and documentation; execution and recordkeeping remain with your import team. Source: CBP First Sale Declaration; USITC pub 4121.
Classification
Getting automotive & parts HTS codes right
In automotive, classification is not clerical — it decides which duty regime hits and at what rate. A component is heading 8708 (parts of motor vehicles) only if it is identifiable as solely or principally for vehicles of headings 8701-8705, is not excluded by Section XVII Legal Note 2, and is not more specifically provided for elsewhere. Note 2 pulls a lot off the car: 'parts of general use' like fasteners, springs, locks, and brackets, plus most engines and engine parts (Chapter 84) and electrical apparatus and wiring (Chapter 85). That fork is where money moves. The same engine, transmission, or wiring set can land in 8708 or in its Chapter 84/85 home — and covered auto parts span Chapters 40, 70, 73, 83, 84, 85, 87, 90, and 94, so many of those parts still fall under the 25% auto-parts 232 tariff. But a part coded to a bare steel or aluminum line can instead trip metals-232 at up to 50%. At the vehicle level, 8703 (persons, 2.5%) versus 8704 (goods, 25%) turns on principal design, not marketing. Our HTS Classification Researcher runs GRI legal reasoning — including GRI 3(b) essential-character calls and CROSS ruling logic — and returns an audit-ready report, so the coding decision is defensible under reasonable care rather than a guess.
Case law & tariff engineering
Precedents every automotive & parts importer should know
Ford Motor Co. v. United States — Transit Connect (Fed. Cir. 2019)
Ford imported Transit Connect vans from Turkey with a second-row seat and belts, declared them as 8703 passenger vehicles at 2.5%, then stripped the rear seats to sell as cargo vans. The Court of International Trade first ruled for Ford, but the Federal Circuit reversed on June 7, 2019 (No. 18-1018), holding the vans classified under 8704 (cargo, 25%): 'principally designed for the transport of persons' incorporates design intent, and the vehicles' auxiliary features showed they were not principally passenger vehicles. Ford separately paid a $365 million settlement in 2024. The lesson: tariff engineering must change the good's character at the time of importation, not paperwork you undo afterward.
Marubeni America Corp. v. United States, 35 F.3d 530 (Fed. Cir. 1994)
The vehicle was the Nissan Pathfinder, which Customs classified as 8704 (goods) and Marubeni argued belonged in 8703 (persons, 2.5%). The court held 8703: to be 'principally designed for the transport of persons,' a vehicle must be designed more for persons than goods, weighing both structural and auxiliary design features. This design-intent test is the same reasoning the Federal Circuit later applied against Ford.

FAQ
Automotive & Parts importer questions
What's the tariff on imported auto parts in 2026?
Most auto parts carry ~2.5% base MFN plus a 25% Section 232 auto-parts tariff (HTS 9903.94.05, effective May 3, 2025); USMCA-qualifying parts are currently 0% (9903.94.06), and China-origin parts add 25% Section 301 (List 3). Rates as of July 2026 — verify current status. Source: USITC HTS; CBP CSMS #64913145.
Do Section 232 auto tariffs stack with the steel and aluminum tariffs?
No. Under the anti-stacking Executive Order of April 29, 2025, the auto and auto-parts Section 232 tariff has primacy, so steel/aluminum/copper Section 232 and IEEPA duties do not also apply to the same article. Base MFN, Section 301, and AD/CVD still stack. Source: CBP IEEPA FAQ.
How does the April 6, 2026 steel and aluminum change affect car parts?
As of April 6, 2026, metals-232 applies to the full customs value of a covered article rather than just its metal content — 25% for derivatives over 15% metal by weight, 50% for mostly-metal goods. Parts already under the auto-parts 232 tariff are shielded from it by primacy. Source: CBP CSMS #68253075. Verify current status.
Are USMCA auto parts still duty-free?
USMCA-qualifying parts are currently 0% under HTS 9903.94.06, but only if the goods meet 75% regional value content, 40-45% labor-value content, and 70% North American steel and aluminum sourcing, plus core-parts rules. A 2026 USMCA review is underway — verify current status. Source: USTR USMCA Autos fact sheet; CRS IF12082.
Can I get a duty refund on exported vehicles or parts?
Yes — duty drawback can return up to 99% of eligible duties on imported inputs that are later exported, but Section 232 duties are not drawback-eligible, so the dominant 25% auto-parts layer is not recoverable; Section 301, MFN, and user fees are. We estimate your recoverable amount and file through a partner drawback provider, with no guaranteed figure. Source: CBP drawback trade-remedy FAQ.
Is the chicken tax still 25%?
Yes. Cargo vans and light trucks classified under heading 8704 carry a 25% base MFN rate — the 'chicken tax' — independent of Section 232. Passenger vehicles under 8703 remain at 2.5% base MFN. Source: USITC HTS Chapter 87.
How is a vehicle classified as 8703 versus 8704?
It turns on whether the vehicle is principally designed for the transport of persons (8703, 2.5%) or goods (8704, 25%), judged on design and use at the time of importation, not on marketing. The Marubeni (Nissan Pathfinder) and Ford (Transit Connect) cases both applied this design-intent test. Source: 35 F.3d 530; Fed. Cir. No. 18-1018.
Why did Ford pay $365 million over the Transit Connect?
Ford imported vans with rear seats declared as 8703 passenger vehicles at 2.5%, then stripped the seats to sell them as cargo vans. The Federal Circuit held them 8704 at 25% in 2019, and Ford settled related claims for $365 million in 2024 — a reminder that tariff engineering must change the good's condition at importation, not afterward.
Do foreign-trade zones still cut auto tariffs through inverted tariff?
Largely no for the trade-remedy layers: Section 232 and Section 301 goods admitted to an FTZ must enter in Privileged Foreign status, which locks the remedy rate at admission and blocks the inverted-tariff benefit. FTZs still provide duty deferral, MPF savings, and relief on re-export. Source: CBP Section 232 and Section 301 FAQs.
What tariffs apply to Chinese auto parts right now?
As of July 2026, a typical China-origin part carries roughly 2.5% MFN + 25% Section 301 (List 3) + 25% Section 232 auto parts, about 52.5% combined; auto-232 primacy blocks an additional metals-232 layer. Confirm the exact rate for your HTS line and origin. Source: USITC HTS; USTR Section 301.
Are engines and transmissions taxed as auto parts or as machinery?
They are classified in Chapter 84 (8407/8408 engines, 8483 transmission components) for base purposes, but they fall within the covered auto-parts 232 scope — which spans Chapters 84 and 85 — so they carry the 25% tariff under 9903.94.05 unless USMCA-qualifying. Source: CBP CSMS #64913145; USITC HTS.
How do I recover customs duties I've overpaid on car imports?
File a protest within 180 days of liquidation under 19 U.S.C. § 1514 (CBP Form 19, filed electronically in ACE); if granted, you receive a refund plus interest. Classification, valuation, and origin errors are all protestable, and the deadline is strictly enforced with no extensions. Source: CBP Protests; 19 U.S.C. § 1514.
