HS code for V-ribbed belt: 4010.33

Rubber, vulcanised, endless transmission belts of trapezoidal cross-section (V-belts), V-ribbed, of an outside circumference exceeding 180cm but not exceeding 240 cm.

Classification of V-ribbed belt under HS 4010.33

V-ribbed belts are classified under HS code 4010.33, a highly specific code within the category of transmission belts made of vulcanized rubber. To fall under this code, the belt must meet three strict criteria: it must be an "endless" belt (joined in a continuous loop), it must have a trapezoidal cross-section (V-belt), and it must be V-ribbed. Furthermore, the classification is size-dependent, specifically covering belts with an outside circumference exceeding 180 cm but not exceeding 240 cm. These belts are commonly used in heavy-duty automotive engines and industrial machinery to transmit power between pulleys. The ribs provide a larger surface area for grip compared to standard V-belts, allowing for higher power transmission in a more compact space.

Codes often confused with 4010.33

Common mistake. The most frequent misclassification involves HS code 4010.31, which covers V-ribbed belts with a circumference between 60 cm and 180 cm. Conversely, belts exceeding 240 cm fall under 4010.39. Misclassification also occurs with 4010.32 or 4010.34, which are for standard V-belts that are not ribbed. Precise measurement of the outside circumference is essential for correct entry.

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).
