🎯 Classification Logic
The core basis for classification is: 1. Material is vulcanized rubber; 2. Use is transmission belt; 3. Cross-sectional shape is V-shaped; 4. Outer circumference is between 240-300cm; 5. It is endless (closed loop). Only when all these conditions are met simultaneously can it be classified under 401034. If the outer circumference exceeds the range or the cross-sectional shape is different, it is classified under other subheadings. 401031 Endless transmission belts of vulcanized rubber, V-shaped, outer circumference 60-180cm: Different outer circumference range; 401031 is 60-180cm, while 401034 is 240-300cm. 401032 Endless transmission belts of vulcanized rubber, V-shaped, outer circumference 180-240cm: Different outer circumference range; 401032 is 180-240cm, while 401034 is 240-300cm. 401033 Endless transmission belts of vulcanized rubber, trapezoidal cross-section, outer circumference 240-300cm: Different cross-sectional shape; 401033 is trapezoidal cross-section, while 401034 is V-shaped cross-section. 401035 Endless transmission belts of vulcanized rubber, synchronous belts, outer circumference 60-150cm: Different cross-sectional shape and circumference; 401035 is synchronous belts, outer circumference 60-150cm. 401039 Other transmission belts of vulcanized rubber: Other subheading, applicable to transmission belts that do not meet the above specific shape and circumference conditions. Is the material vulcanized rubber? Is it an endless transmission belt? Is the cross-sectional shape V-shaped? Is the outer circumference between 240-300cm? Does it contain reinforcing materials? If so, does it affect classification?

❓ FAQ
How to accurately measure the outer circumference of a V-belt? The outer circumference should be measured along the outer edge of the belt, usually using a soft tape measure tightly around the outer surface. For V-belts, the outer circumference is slightly larger than the pitch length. It is recommended to measure multiple times and take the average, and ensure the belt is in a natural state without stretching. If the outer circumference is exactly 240cm, which code should it be classified under? According to HS coding rules, subheading ranges usually include the lower limit. The outer circumference range of 401034 is 240-300cm, so 240cm should be classified under 401034. However, it is necessary to confirm whether the upper limit is included; usually the upper limit is not included, i.e., 300cm may be classified under the next subheading, subject to customs interpretation. What is the difference between V-belts and trapezoidal belts? V-belts have an isosceles trapezoidal cross-section, with both sides being working surfaces, and the angle is usually 40°. Trapezoidal belts may refer to other shapes, such as wide V-belts or special cross-sections. In HS classification, V-belts specifically refer to transmission belts with a V-shaped cross-section, while trapezoidal belts may refer to other belts with a trapezoidal cross-section. Does the transmission belt containing steel wire reinforcement affect classification? Vulcanized rubber transmission belts containing reinforcing materials (such as steel wire, fiber) are still classified under 4010, because the heading text does not exclude reinforcement. However, the reinforcing material must be indicated during declaration for customs confirmation. Which code should non-endless V-shaped transmission belts be classified under? Non-endless V-shaped transmission belts (i.e., open belts) should be classified under 401039 (other), because 401031-401035 all require endless. Open belts are usually cut to length and not closed. How to inquire about the import tax rate for 401034? Tax rates may change. It is recommended to check the latest tax rates through the General Administration of Customs website, China International Trade Single Window, or professional customs declaration systems. Note that different countries of origin may apply different agreement tax rates. Are brand and model required to be filled in during declaration? Brand and model are important declaration elements that help customs identify the commodity. If no brand, fill in "unbranded"; the model should be filled in as much as possible for verification with the actual product. Omission may cause customs clearance delays. If the transmission belt outer circumference is 310cm, where should it be classified? V-shaped endless transmission belts with an outer circumference exceeding 300cm should be classified under 401039 (other). Because the upper limit of 401034 is 300cm, exceeding it does not conform to that subheading.
