Chapter 40 covers vulcanized rubber and articles thereof, including raw materials such as natural rubber, synthetic rubber, and reclaimed rubber, as well as various rubber semi-finished and finished products. This chapter classifies products according to the form, degree of processing, and use of rubber, covering everything from raw rubber to final products. The key distinction lies in whether vulcanization treatment has been applied, as well as the specific use and shape of the products. Heading 4010 covers conveyor belts or transmission belts of vulcanized rubber, including V-belts, endless belts, etc. These belts are mainly used for mechanical power transmission or material conveyance and must possess a certain degree of strength and wear resistance. This heading distinguishes different cross-sectional shapes (such as V-shaped and trapezoidal) and perimeter ranges to meet the specification requirements of different mechanical equipment. The first 2 digits 40 represent Chapter 40 (Rubber and articles thereof). Digits 3-4, 10, represent heading 4010 (conveyor belts or transmission belts of vulcanized rubber). Digits 5-6, 33, represent subheading 401033, specifically referring to V-shaped endless transmission belts with an outer circumference between 180 cm and 240 cm. This subheading further refines the size range of V-belts to facilitate customs classification based on circumference. This commodity is a V-shaped endless transmission belt of vulcanized rubber with an outer circumference between 180-240 cm, fully conforming to the description of 401033. Adjacent codes such as 401031 (outer circumference 60-180 cm) and 401035 (outer circumference 240-300 cm) are excluded due to circumference mismatch. Meanwhile, non-V-shaped or non-endless belts are classified under other subheadings, so this code is the only correct classification.

Product Name
The specific name of the declared commodity, such as "V-belt" or "V-shaped drive belt," which must be consistent with the actual product.
⚠️ Writing only "rubber belt" is too general and does not reflect the V-shape and transmission use.
Material
Indicate vulcanized rubber, which may be further specified as "natural rubber" or "synthetic rubber," and state whether it contains fabric reinforcement.
⚠️ Incorrectly stating "plastic" or "unvulcanized rubber," leading to classification errors.
Shape
Clearly indicate V-shaped (trapezoidal cross-section) and state whether it is endless (jointless) or in another form.
⚠️ Misreporting V-shaped as flat belt or round belt, affecting subheading determination.
Outer Circumference
Accurately measure and declare the outer circumference in centimeters, which must be within the range of 180-240 cm.
⚠️ Confusing inner circumference with outer circumference, or failing to provide specific values.

🎯 Classification Logic
The core basis for classification is: 1. Material is vulcanized rubber; 2. Shape is V-shaped (trapezoidal cross-section); 3. Structure is endless (jointless); 4. Outer circumference is between 180-240 cm; 5. Use is for transmission. All these conditions must be met simultaneously to classify under 401033. If the circumference is not within this range, it is classified under an adjacent subheading; if the shape is not V-shaped, it is classified under another subheading. 401031 V-belts, outer circumference 60-180 cm: Outer circumference range differs; 401031 is 60-180 cm, 401033 is 180-240 cm. 401035 V-belts, outer circumference 240-300 cm: Outer circumference range differs; 401035 is 240-300 cm, 401033 is 180-240 cm. 401039 Other V-belts: Applicable to V-belts with outer circumferences not within the above ranges, or non-endless V-belts. 401012 Conveyor belts of vulcanized rubber: Conveyor belts are used for material conveyance, not power transmission, and may be flat belts in shape. 401011 Steel wire reinforced conveyor belts: Reinforcement material is steel wire, and used for conveyance, not transmission. Is the material vulcanized rubber? Is the shape V-shaped (trapezoidal cross-section)? Is it endless (jointless)? Is the outer circumference between 180-240 cm? Is the use for transmission?

❓ FAQ
How to check the tax rate for HS code 401033? You can check the latest import tax rate and export rebate rate by entering code 401033 on the General Administration of Customs website, the International Trade Single Window, or professional query tools. Tax rates are subject to policy adjustments; it is recommended to refer to the latest official announcements. What is the method for measuring outer circumference? Outer circumference refers to the perimeter of the outer edge of an endless belt. Typically, lay the belt flat and measure around the outside with a tape measure. It can also be estimated by adding twice the belt thickness to the inner circumference, but direct measurement of the outer circumference is recommended for accuracy. If a V-belt has an outer circumference of exactly 180 cm, which code should it be classified under? According to the subheading descriptions, 401031 is 60-180 cm, and 401033 is 180-240 cm. Typically, boundary values include the lower limit, so 180 cm may be classified under 401033, but customs interpretation should be confirmed. It is recommended to provide precise measurements when declaring to avoid disputes. What is the difference in classification between V-belts and synchronous belts? V-belts are classified under 4010, and synchronous belts (toothed belts) are also classified under 4010, but are subdivided according to shape and circumference. Synchronous belts typically have teeth, while V-belts have a trapezoidal cross-section. If it is a synchronous belt, it should be classified under other subheadings of 4010, such as 401036, etc. Is it necessary to provide proof of outer circumference when declaring? Usually no separate proof is required, but customs may request inspection. It is recommended to accurately fill in the outer circumference on the customs declaration form and retain product specifications or test reports for reference. If a V-belt is used for conveying materials, can it be classified under 401033? No. 401033 specifically refers to transmission belts used for power transmission. If used for conveying materials, it should be classified under conveyor belt subheadings, such as 401012, etc. Use is the key to distinguishing transmission belts from conveyor belts. Can imported used V-belts be classified under 401033? Yes, but they must comply with regulations on the import of used mechanical and electrical products. The HS code does not distinguish between new and used, but used items may involve additional regulatory conditions. It is recommended to consult customs. How to avoid customs clearance delays caused by classification errors? Recommendations: 1. Accurately measure the outer circumference; 2. Clearly specify material and shape; 3. Provide detailed product descriptions; 4. Refer to customs classification decisions or advance rulings. If in doubt, you may apply for an advance ruling.
