Chapter 40 covers rubber and articles thereof, including raw materials such as natural rubber, synthetic rubber, and vulcanized rubber, as well as various finished rubber products. This chapter ranges from rubber in primary forms to final products such as tires, tubes, belts, and footwear. Heading 4013 falls under vulcanized rubber products in the tire category, but only covers inner tubes. Heading 4013 specifically refers to new pneumatic rubber tires and inner tubes. Among these, 4013.10 covers tires for motor vehicles, 4013.20 covers tires for bicycles, and 4013.90 covers tires for other uses. Inner tubes under this heading must be independent inner tubes made of rubber and used for pneumatic tires. Code 401390 consists of 6 digits: the first 2 digits 40 represent Chapter 40, rubber and articles thereof; digits 3-4, 13, represent heading 4013, namely new pneumatic rubber tires and inner tubes; digits 5-6, 90, represent subheading 4013.90, namely other rubber inner tubes, referring to rubber inner tubes for uses other than motor vehicles and bicycles, such as agricultural machinery, engineering machinery, aircraft, motorcycles, etc. This product is a rubber inner tube, but it is not for motor vehicles or bicycles, so it cannot be classified under 4013.10 or 4013.20. At the same time, it does not belong to 4011 (new pneumatic rubber tires) or 4012 (retreaded tires), and therefore is classified under 4013.90.

Product name: The specific name of the declared commodity, such as 'rubber inner tube', which must be consistent with the actual goods. Use: Clearly specify the type of vehicle or equipment for which the inner tube is suitable, such as 'for agricultural tractors' or 'for motorcycles'. Material: Indicate the type of rubber, such as 'natural rubber', 'butyl rubber', etc. Brand: Fill in the brand or trademark of the inner tube; if there is no brand, write 'none'. Model: Fill in the specification and model of the inner tube, such as 'XX-XX'. Is it new: Declare whether the inner tube is new or used. Size: Size parameters of the inner tube, such as diameter and width. Product name: rubber inner tube; Use: for agricultural tractors; Material: butyl rubber; Brand: XX; Model: XX-XX; Is it new: new; Size: diameter XX cm. Mistakenly classifying motorcycle inner tubes under 4013.10 (for motor vehicles), when in fact motorcycle inner tubes should be classified under 4013.90. Ignoring the declaration of 'Is it new'; used inner tubes may involve solid waste management and be prohibited from import. False declaration of brand and model may trigger intellectual property infringement or customs questioning.

Core basis for classification: 1. The commodity is a rubber inner tube; 2. The use is not for motor vehicles or bicycles; 3. It is a new pneumatic rubber inner tube. According to the Import and Export Tariff and its notes, 4013.90 covers other rubber inner tubes, such as those for aircraft, motorcycles, engineering machinery, etc. 401310 Rubber inner tubes for motor vehicles: Used for motor vehicles such as automobiles, buses, and trucks, whereas 401390 is used for non-motor vehicles or special purposes. 401320 Rubber inner tubes for bicycles: Specifically for bicycles, whereas 401390 is used for motorcycles, aircraft, etc. 401110 New pneumatic rubber tires for motor vehicles: These are outer tires, not inner tubes; 401390 is for inner tubes. 401120 New pneumatic rubber tires for buses or goods transport motor vehicles: These are also outer tires, and the use is different. Is it a rubber inner tube? Is it for motor vehicles or bicycles? Is it new? Is it for other specific uses? Is it confused with 4011 or 4012?

Which HS code should motorcycle inner tubes be classified under? Motorcycle inner tubes do not belong to motor vehicles (4013.10) or bicycles (4013.20), and should be classified under 4013.90. How do you distinguish between 4013.90 and 4013.10? 4013.10 applies only to inner tubes for motor vehicles such as automobiles and trucks; 4013.90 applies to inner tubes for all other uses, such as motorcycles, aircraft, engineering machinery, etc. Can used rubber inner tubes be imported? Used rubber inner tubes may be classified as solid waste and are prohibited from import. If import is permitted, they must comply with relevant regulations, and the classification may differ. Must brand and model be filled in during declaration? Yes, brand and model are important declaration elements. If there is no brand, write 'none'; the model must be filled in truthfully, otherwise customs clearance may be affected. What is the difference in classification between rubber inner tubes and tires? Inner tubes are classified under 4013, while outer tires are classified under 4011 or 4012. An inner tube is an independent inflatable component, while an outer tire is the component that directly contacts the ground. Which code should agricultural machinery inner tubes be classified under? Agricultural machinery inner tubes belong to other rubber inner tubes and should be classified under 4013.90. Which code should aircraft inner tubes be classified under? Aircraft inner tubes are also classified under 4013.90, because aircraft are not motor vehicles or bicycles. How can I check the tax rate for 401390? The tax rate must be checked according to the latest Import and Export Tariff, and can be obtained through the General Administration of Customs website or professional tariff query tools.
