Chapter 84 is the collective term in the HS classification for "nuclear reactors, boilers, machinery and mechanical appliances and parts thereof," covering a broad range from power machinery to precision machinery. Goods of this chapter generally have the function of being power-driven, converting motion, or performing work, but exclude electrical equipment (Chapter 85) and vehicles (Chapter 87). Heading 8482 falls within the category of "rolling bearings," which are fundamental components of mechanical transmission and are widely used in electric motors, automobiles, machine tools, etc. The notes to this chapter strictly define the scope, and classification requires a comprehensive judgment based on function, material, and use. Heading 8482 covers all rolling bearings, including ball bearings, roller bearings, needle roller bearings, etc., regardless of their field of application. Rolling bearings reduce friction through rolling elements and support rotating shafts. This heading is subdivided into multiple subheadings, such as 8482.10 ball bearings, 8482.20 tapered roller bearings, 8482.30 spherical roller bearings, etc. 8482.40 specifically refers to cylindrical roller bearings, whose rolling elements are cylindrical and which are suitable for bearing relatively large radial loads. Note: If bearing parts such as inner rings, outer rings, and rolling elements are declared separately, they are generally classified under 8482.99, but complete bearings are classified under the corresponding subheading. Code 848240 is a 6-digit HS subheading. The first 2 digits "84" represent Chapter 84 (nuclear reactors, boilers, machinery and mechanical appliances and parts thereof), indicating that the goods belong to the machinery category. The 3rd-4th digits "82" represent heading 8482 (rolling bearings), which is a secondary classification under Chapter 84 divided according to function. The 5th-6th digits "40" represent subheading 8482.40 (cylindrical roller bearings), which is a further subdivision under the rolling bearings heading according to the shape of the rolling elements. Therefore, 848240 fully represents "cylindrical roller bearings," and its classification logic is in sequence: machinery chapter -> rolling bearings heading -> cylindrical roller bearings subheading. The rolling elements of cylindrical roller bearings are cylindrical, and compared with ball bearings (8482.10), tapered roller bearings (8482.20), spherical roller bearings (8482.30), etc., their structural characteristics are obvious. During classification, it must be confirmed that the shape of the rolling elements is cylindrical, not conical or spherical. If they are needle roller bearings (8482.50), their rolling elements are slender and also different from cylindrical rollers. Therefore, according to the geometric shape of the rolling elements, cylindrical roller bearings are accurately classified under 8482.40 rather than adjacent subheadings.

Product name: The Chinese and foreign-language names of the declared goods should accurately reflect the bearing type, such as "cylindrical roller bearing." Brand: Fill in the brand or manufacturer name of the bearing, such as SKF, NSK, etc.; if there is no brand, fill in "no brand." Model: Fill in the specific model or specification of the bearing, such as NU206, NJ310, etc., to facilitate customs identification. Structure type: Explain the structure of the bearing, such as single row, double row, whether the outer ring has ribs, etc., which affects subheading subdivision. Rolling element material: Fill in the material of the rolling elements, such as bearing steel, ceramics, etc.; the material affects classification and tariff rates. Inner diameter: Fill in the bearing inner diameter size in millimeters, which is an important technical parameter. Outer diameter: Fill in the bearing outer diameter size in millimeters; together with the inner diameter, it determines the specification. Use: Fill in the application field of the bearing, such as automobile gearboxes, electric motors, etc.; the use affects classification. Product name: cylindrical roller bearing; Brand: SKF; Model: NU206ECP; Structure type: single row, outer ring without ribs; Rolling element material: bearing steel; Inner diameter: 30mm; Outer diameter: 62mm; Use: used for industrial motors. Mistakenly declaring cylindrical roller bearings as needle roller bearings; the two have different rolling element shapes. Ignoring the structure type (single row/double row), resulting in incorrect subheading classification. False declaration of brand and model may trigger customs questions and inspection.

The core basis for classification is the geometric shape of the bearing's rolling elements. The rolling elements of cylindrical roller bearings are cylindrical, and the ratio of their length to diameter is usually less than 3, and they are arranged in parallel. According to General Interpretative Rule 1 and the notes to Chapter 84, rolling bearings are classified under 8482 by type. Because the rolling element shape of cylindrical roller bearings is clear, they are classified under 8482.40. If the rolling elements are conical, they are classified under 8482.20; if they are spherical rollers, under 8482.30; if they are needles (length-to-diameter ratio greater than 3), under 8482.50. Therefore, accurately determining the shape of the rolling elements is the key to classification. 848210 Ball bearings: The rolling elements are spheres and mainly bear radial and axial loads, whereas cylindrical roller bearings have cylindrical rolling elements and mainly bear radial loads. 848220 Tapered roller bearings: The rolling elements are conical and can bear combined radial and axial loads, unlike the cylindrical rolling elements of cylindrical roller bearings. 848230 Spherical roller bearings: The rolling elements are spherical rollers and have self-aligning capability, able to compensate for shaft misalignment, whereas cylindrical roller bearings have no self-aligning function. 848250 Needle roller bearings: The rolling elements are slender needles with a length-to-diameter ratio greater than 3, small radial dimensions, and high load capacity, unlike the cylinders of cylindrical roller bearings. Confirm whether the rolling elements are cylindrical Check whether the bearing is complete, not a part Verify that the brand and model match the actual goods Confirm that the inner and outer diameter dimensions are correct Confirm that the use description is specific and clear

What is the difference in HS codes between cylindrical roller bearings and needle roller bearings? Cylindrical roller bearings are classified under 8482.40, and needle roller bearings under 8482.50. The main difference lies in the shape of the rolling elements: the rolling elements of cylindrical roller bearings are cylindrical, with a relatively small length-to-diameter ratio (usually less than 3); the rolling elements of needle roller bearings are slender, with a length-to-diameter ratio greater than 3. Classification must be judged based on the actual goods or drawings. How can I check the import tariff rate for cylindrical roller bearings? First determine HS code 848240, then check according to the customs tariff of the destination country. For imports into China, consult the "Import and Export Tariff of the People's Republic of China," or check through the General Administration of Customs website or the single window. Tariff rates include MFN rates, general rates, VAT, etc., and the specific rate at the time of declaration shall prevail. What declaration elements must be provided when declaring cylindrical roller bearings? Usually, product name, brand, model, structure type (single row/double row), rolling element material, inner diameter, outer diameter, use, etc. are required. Different customs authorities may have slightly different requirements; it is recommended to consult in advance or check the latest declaration specifications. Under which code should parts of cylindrical roller bearings (such as inner rings) be classified? If declared separately, bearing parts are generally classified under 8482.99 (other parts of rolling bearings). However, if declared together with a complete bearing, they are classified as a complete bearing. Note: If inner rings, outer rings, rolling elements, etc. have been assembled into a complete bearing, they are classified under 8482.40. For cross-border e-commerce retail of cylindrical roller bearings, is the HS code the same? Yes, HS classification does not change due to the mode of trade. Cross-border e-commerce retail exports must also be classified according to the actual attributes of the goods, and cylindrical roller bearings are still classified under 848240. However, attention should be paid to the difference between personal items and goods declaration, as well as policies such as tax exemption limits. If cylindrical roller bearings are used in automobiles, are they classified under automobile parts codes? No. Rolling bearings have a dedicated heading 8482, and even if specially used for automobiles, they should be classified under 8482.40, not automobile parts (such as 8708). According to the General Rules for classification, if a part is a general mechanical component and is specifically named in another heading, it should be classified under that heading first. How can single-row and double-row cylindrical roller bearings be distinguished? Single-row cylindrical roller bearings have only one row of rolling elements, a simple structure, and bear radial loads; double-row cylindrical roller bearings have two rows of rolling elements, with stronger load capacity and better rigidity. When declaring, the structure type must be clearly indicated based on the actual goods or drawings for customs classification. Is the classification of cylindrical roller bearings affected by material? HS code 848240 is mainly classified according to the shape of the rolling elements; the material (such as bearing steel, ceramics) does not affect the subheading, but may affect the tariff rate (for example, certain materials may have special rates). When declaring, the material must still be truthfully filled in for customs review.
