How to Classify Auto Parts Under the HTS
Camtom Team1 de marzo de 202610 min
Automotive parts represent one of the most complex areas of tariff classification. Unlike finished vehicles that fall squarely under Chapter 87, auto parts can be classified across more than a dozen different HTS chapters depending on their material, function, and specificity to automotive use. A steel bracket might classify in Chapter 73 (articles of iron or steel), an electronic control unit in Chapter 85 (electrical machinery), and a rubber gasket in Chapter 40 (rubber). The duty rates across these chapters can vary dramatically — from duty-free to over 6% — making correct classification essential for accurate cost planning.
The fundamental classification question for any auto part is: does it belong in Chapter 87 (vehicles and parts thereof) or in the chapter that covers its constituent material or function? The general rule is that parts and accessories identifiable as solely or principally designed for vehicles classify in Chapter 87, subheadings 8708 (motor vehicle parts) or 8714 (bicycle/motorcycle parts). Parts that have a more general application — such as bolts, pumps, bearings, or electrical connectors — classify in their respective functional chapters even if they are used in vehicles.
Use TariffPro to classify auto parts quickly. Enter the specific part name along with its function, material, and whether it is solely or principally for motor vehicle use. TariffPro will analyze the description against both Chapter 87 and the relevant functional chapters to suggest the correct heading.
The key test is whether the part is solely or principally designed for use with motor vehicles. A car door handle is solely for vehicles — it has no other application. A ball bearing, however, is used in vehicles, industrial machinery, appliances, and many other products, so it classifies under its functional heading (Chapter 84, subheading 8482) rather than Chapter 87. When in doubt, check CBP rulings for similar parts through the CROSS database.
Some auto parts serve multiple functions or are composed of materials from different chapters. For example, a dashboard assembly may include plastic, electronics, and metal. GRI 3(b) classifies composite goods by the component that gives them their essential character. For a dashboard, the essential character is typically the plastic housing and structure (Chapter 39 or Chapter 87 depending on specificity). For a GPS navigation unit that could work in or out of a vehicle, the electronic function (Chapter 85) usually prevails.
Many auto parts sourced from China are subject to Section 301 tariffs, adding an additional 25% duty on top of the Column 1 General rate. The Section 301 tariff applies based on the HTS code, not the end use — so a part classified under Chapter 85 might face Section 301 duties even though it is for automotive use. Always check whether your HTS code appears on the Section 301 tariff lists (Lists 1-4A) and whether any exclusions apply to your specific product.
Misclassifying auto parts to avoid Section 301 tariffs is a compliance violation that CBP actively monitors. The agency has issued dozens of penalty actions against importers who improperly classified parts between chapters to circumvent additional duties. Always classify based on the product characteristics, not the desired duty rate.
For auto parts, especially high-volume imports, maintain a classification database that documents the rationale for each part number. Include the HTS code, the GRI analysis, any CBP rulings referenced, and the date of last review. This documentation demonstrates reasonable care and is your best defense in the event of a CBP audit. TariffPro maintains a classification history for every product you confirm, creating an automatic audit trail.
