HS Code for Drive belt

The classification of drive belts under HS code 4010.36 is determined by the material composition, the physical construction, and the specific dimensions of the product. According to the General Rules of Interpretation (GRI) 1 and 6, this code is reserved for transmission belts made of vulcanized rubber. Specifically, the term "endless" refers to a belt that is manufactured in a continuous loop without a seam or mechanical fastener. The term "synchronous" indicates that the belt features teeth or lugs on the inner surface, designed to mesh with grooved pulleys to prevent slipping and ensure precise timing in mechanical systems. For a belt to fall under 4010.36, its outside circumference must be greater than 150 cm but not exceed 198 cm. This precise measurement is a critical legal threshold; belts falling outside these dimensions are classified under adjacent subheadings such as 4010.35 or 4010.39. The rubber must be vulcanized, which is a chemical process that increases the durability and elasticity of the material, distinguishing it from unvulcanized rubber products found in Chapter 40.

Products Included

• Industrial synchronous timing belts with a 160 cm circumference
• Reinforced rubber toothed belts for heavy machinery (180 cm)
• Endless transmission belts for agricultural equipment (195 cm)
• High-torque drive belts within the 150-198 cm range

Common Misclassification

Drive belts are frequently misclassified under HS code 4010.35 if the circumference is exactly 150 cm or less, or under 4010.39 if the circumference exceeds 198 cm. Another common error is attempting to classify these belts under heading 8483 as parts of transmission equipment. However, Note 1(a) to Section XVI explicitly excludes articles of vulcanized rubber used in machinery, directing them back to Chapter 40. Additionally, non-synchronous belts (like V-belts) are classified under 4010.31 through 4010.34, depending on their profile and size.

FAQ

What is the HS code for Drive belt?

The HS code for an endless synchronous drive belt made of vulcanized rubber with an outside circumference between 150 cm and 198 cm is 4010.36.

Does the material reinforcement affect this classification?

No, as long as the primary component is vulcanized rubber, the presence of textile or metal reinforcements within the rubber matrix does not change the classification from heading 4010.
