Chapter 40 covers rubber and articles thereof, including natural rubber, synthetic rubber, reclaimed rubber, unvulcanized rubber, vulcanized rubber, and various rubber articles. This chapter classifies rubber according to its form, degree of processing, and use, ranging from raw rubber to semi-finished and finished products. Vulcanized rubber articles are an important part of this chapter, including tires, rubber hoses, transmission belts, conveyor belts, etc. Heading 4010 specifically covers transmission belts or conveyor belts of vulcanized rubber, including V-belts, synchronous belts, flat belts, etc. These belts are mainly used for mechanical power transmission or material conveyance. They are further subdivided according to shape, outer circumference, material, etc. Heading 4010 includes endless transmission belts, conveyor belts, etc., but excludes plates, sheets, and strips of pure rubber (classified under 4008) or belts combined with metal (classified under other chapters). The first 2 digits 40: indicates Chapter 40, rubber and articles thereof. The 3rd-4th digits 10: indicates heading 4010, transmission belts or conveyor belts of vulcanized rubber. The 5th-6th digits 32: indicates subheading 401032, specifically endless transmission belts of vulcanized rubber, V-shaped, with an outer circumference of 60-180 cm. This subheading further limits the shape (V-shaped), structure (endless), and size (outer circumference 60-180 cm). This commodity is a V-shaped endless transmission belt of vulcanized rubber, with an outer circumference between 60-180 cm, fully conforming to the description of 401032. The adjacent code 401031 is for endless transmission belts with a trapezoidal cross-section and an outer circumference of 60-180 cm (a type of V-belt), but 401032 specifically refers to V-belts, while 401031 is for trapezoidal belts, and the cross-sectional shapes of the two are different. 401033 is for V-belts with an outer circumference of 180-240 cm, and the size does not match.

🎯 Classification Logic
The core basis for classification is: 1. Material is vulcanized rubber; 2. Use is transmission belt; 3. Structure is endless; 4. Cross-sectional shape is V-shaped; 5. Outer circumference is between 60-180 cm. All these conditions must be met simultaneously to be classified under 401032. If the cross-section is trapezoidal, it is classified under 401031; if the outer circumference is not within the range, it is classified under other subheadings. 401031 Endless transmission belts with trapezoidal cross-section, outer circumference 60-180 cm: The cross-sectional shape is trapezoidal, whereas 401032 is V-shaped. Trapezoidal belts are usually used for specific machinery, while V-belts are more common. 401033 V-shaped endless transmission belts, outer circumference 180-240 cm: The outer circumference range is different; 401033 is 180-240 cm, exceeding the 60-180 cm of 401032. 401035 Synchronous belts, outer circumference 60-150 cm: Synchronous belts have teeth and are used for precise transmission, while V-belts rely on friction for transmission. 401039 Other transmission belts of vulcanized rubber: A residual subheading for transmission belts not elsewhere specified, such as flat belts and specially shaped belts. Is the material vulcanized rubber? Is it an endless transmission belt? Is the cross-sectional shape V-shaped? Is the outer circumference between 60-180 cm? Is it used for power transmission rather than conveying materials?

❓ FAQ
How to distinguish V-belts from trapezoidal belts? The cross-section of a V-belt is an isosceles triangle, and the angle between the two working surfaces is usually 40 degrees; the cross-section of a trapezoidal belt is trapezoidal, with the two working surfaces parallel or at a certain angle. The two belong to different subheadings in the HS code and must be declared according to the actual cross-sectional shape. How is the outer circumference measured? The outer circumference should be measured along the outer edge of the transmission belt. Usually, the belt is laid flat, and a tape measure is placed tightly around the outer edge. Be careful not to measure the inner circumference or pitch circumference, otherwise the size may fall into a different subheading. If the outer circumference is exactly 180 cm, which subheading does it fall under? According to HS coding rules, 401032 is 60-180 cm, including 180 cm; 401033 is 180-240 cm, also including 180 cm. In this case, reference should be made to the General Rules for Interpretation, usually giving priority to the specific description, but it is recommended to rely on the actual customs ruling or provide precise measurement data. What is the difference in classification between transmission belts and conveyor belts? Transmission belts are used to transmit power, while conveyor belts are used to convey materials. In the HS code, under heading 4010, transmission belts and conveyor belts are listed under different subheadings. Transmission belts are usually endless and have various cross-sectional shapes; conveyor belts are usually flat belts and may have reinforcing materials. How to distinguish vulcanized rubber from unvulcanized rubber? Vulcanized rubber has undergone vulcanization treatment and has elasticity, heat resistance, etc.; unvulcanized rubber has good plasticity but low strength. In the HS code, unvulcanized rubber articles are classified under 4005-4009, and vulcanized rubber articles are classified under 4010 and later. If the transmission belt has joints, can it be classified under 401032? 401032 requires endless transmission belts, usually referring to endless belts without joints. If it has joints, it may be classified under 401039 or other subheadings. However, if the joint is a permanent connection and the whole is endless, it may still be classified under 401032, depending on the specific situation. How to check the tax rate for 401032? Tax rates vary by country, trade agreement, origin, etc. The latest tax rate can be checked through the official website of the General Administration of Customs, the International Trade Single Window, or by consulting a customs broker. It is recommended to rely on the customs system data at the time of actual declaration. Is a test report required for declaration? Usually not required, but customs may require proof of material, dimensions, etc. It is recommended to keep product specifications, measurement records, etc., for inspection. If it involves a brand or special use, relevant certificates may be required.
