Product classification
HS code for Timing belt: 4010.36
Rubber, vulcanised, endless synchronous belts, of an outside circumference exceeding 150 cm but not exceeding 198 cm.
Classification of timing belt under HS 4010.36
Timing belts with an outside circumference between 150 cm and 198 cm are classified under HS code 4010.36. This classification is found within Chapter 40, which covers rubber and articles thereof. Heading 4010 specifically addresses conveyor or transmission belts or belting of vulcanized rubber. The subheading 4010.36 is reserved for "endless synchronous belts," commonly known as timing belts, which feature teeth on the inner surface to ensure precise, non-slip power transmission. The classification is highly specific, requiring the belt to be made of vulcanized rubber and to fall within the precise measurement range of 150 cm to 198 cm in circumference. These belts are critical components in automotive engines and industrial machinery where synchronization between shafts is required. The HS system uses these specific measurement brackets to differentiate between various industrial applications and to facilitate accurate trade monitoring for different sizes of drive components.

Codes often confused with 4010.36
Common mistake. Timing belts are often misclassified under other subheadings of 4010. For instance, 4010.35 covers belts with a circumference of 60 cm to 150 cm, while 4010.39 covers other synchronous belts. Misclassification also occurs when users attempt to classify them as engine parts under 8409; however, according to Section XVI Note 1(a), belts of vulcanized rubber are excluded from that section and must be classified in Chapter 40.
Top exporters and importers of HS 401036 (the code used for timing belt), 2025
In 2025, the largest exporter of HS 401036 (the code used for timing belt) in UN Comtrade data was Germany, with 22% of world exports; the largest importer in UN Comtrade data was the United States, with 19% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).

Questions about timing belt
What is the HS code for Timing belt?
The HS code for Timing belt is 401036 (Rubber; vulcanised, endless synchronous belts, of an outside circumference exceeding 150 cm but not exceeding 198 cm). For an endless synchronous rubber belt with a circumference between 150 cm and 198 cm, the HS code is 4010.36.
How do I classify Timing belt for customs?
Timing belt is classified under HS code 401036 — Rubber; vulcanised, endless synchronous belts, of an outside circumference exceeding 150 cm but not exceeding 198 cm. This is a 6-digit subheading level code.
How is the circumference of a timing belt measured for HS classification?
The circumference is measured as the outside length of the belt in its "endless" (looped) state, typically following the pitch line of the teeth.
Which countries are the top exporters of timing belt (HS 401036)?
In 2025, the top exporters of HS 401036 (the code used for timing belt) in UN Comtrade data were Germany ($19M, 22% of world exports), Japan ($12M) and Italy ($12M). World exports came to about $84M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
