HS Code 4010.31 – Rubber; vulcanised, endless transmission belts of trapezoidal cross-section (V-belts), V-ribbed, of an outside circumference exceeding 60cm but not exceeding 180 cm

HS code 4010.31 is the 6-digit subheading for rubber, vulcanised, endless transmission belts of trapezoidal cross-section (V-belts), V-ribbed, of an outside circumference exceeding 60cm but not exceeding 180 cm. It is used for automotive serpentine belt, industrial V-ribbed belt, multi-ribbed drive belt, engine accessory belt and HVAC fan belt.

What HS 4010.31 covers

This HS code covers vulcanised rubber endless transmission belts of trapezoidal cross-section (V-belts) that are V-ribbed, with an outside circumference exceeding 60 cm but not exceeding 180 cm. These multi-ribbed belts are highly efficient for power transmission, commonly found in automotive accessory drives (e.g., alternators, power steering pumps) and various industrial machinery where multiple components need to be driven simultaneously. Importers include automotive parts distributors, industrial equipment manufacturers, and aftermarket suppliers. Exporters are major global belt manufacturers known for precision engineering. Key trade factors involve the number of ribs, material composition for durability and flexibility, and adherence to specific dimensional standards (e.g., PK, PJ profiles) to ensure compatibility and optimal performance in demanding applications.

Codes often confused with 4010.31

Common mistake. This code is often confused with 401032 (non-ribbed V-belts) or 401033 (larger V-ribbed belts). The 'V-ribbed' feature and the specific 'circumference range' are the defining characteristics.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
