Frequently Asked Questions
What are specific customs inspection risks for automotive gearboxes under HTS 8708.40?
Gearboxes under 8708.40 are frequently inspected for correct classification to avoid misclassification under more general parts headings, which carries a risk of duty underpayment and penalties. Inspectors also scrutinize the country of origin markings and documentation, as certain gearbox assemblies may be subject to Section 232 tariffs or other trade remedies depending on their source.
What additional duties or fees beyond the standard tariff rate should I expect when importing automotive gearboxes under HTS 870840?
For HTS 870840, you must pay the 2.5% Most Favored Nation (MFN) duty rate, but also account for the Merchandise Processing Fee (MPF), which is 0.3464% of the entered value (minimum $31.67, maximum $634.62). If your gearboxes originate from a country subject to Section 301 tariffs (e.g., China), an additional 2.5% duty applies on the entered value.
Compliance Notes for Automotive Gearboxes (870840)
Imports under HTS 870840 must comply with the Federal Motor Vehicle Safety Standards (FMVSS) and meet EPA emission requirements if part of a propulsion system. Gearboxes containing asbestos-based friction components are prohibited under the Toxic Substances Control Act (TSCA). For manual transmissions, ensure proper classification of synchronizer assemblies, which may be separately classified under 8708.99 (e.g., 8708.99.8180). All applicable Section 301 tariffs, such as the 2.5% duty on certain Chinese-origin automotive parts, must be declared and paid.
