Chapter 84 is a major category in the HS classification system, covering nuclear reactors, boilers, machinery, mechanical appliances, and their parts. This chapter includes general mechanical components such as power machinery, pumps, fans, bearings, gears, transmission devices, and seals, as well as machine tools, office equipment, and automatic data processing equipment. Heading 8482 falls under the general mechanical parts section of this chapter, specifically for bearings. Heading 8482 covers rolling bearings, including ball bearings, roller bearings, needle roller bearings, etc., as well as their parts (such as balls, rollers, cages, etc.). However, it does not include plain shaft bearings (classified under 8483) or bearing housings (classified under 8483). Bearings under this heading are further subdivided by type and structure. The first 2 digits 84: indicates Chapter 84, i.e., nuclear reactors, boilers, machinery, mechanical appliances, and their parts. The 3rd-4th digits 82: indicates heading 8482, i.e., rolling bearings. The 5th-6th digits 30: indicates subheading 848230, i.e., spherical roller bearings. Spherical roller bearings specifically refer to rolling bearings with spherical-shaped rollers that can self-align, usually of double-row construction. This commodity is a spherical roller bearing, characterized by spherical rollers and self-aligning capability, which conforms to the description of subheading 848230. Compared with adjacent codes such as 848210 (ball bearings), 848220 (tapered roller bearings), and 848240 (needle roller bearings), its roller shape and self-aligning function are the core differences, so it is classified under 848230.

Product Name: The Chinese and foreign language names of the declared commodity, which should accurately reflect the bearing type, such as "spherical roller bearing" or "self-aligning roller bearing". Brand: Fill in the brand or manufacturer name of the bearing, such as SKF, FAG, NSK, etc.; if there is no brand, fill in "no brand". Model: Fill in the specific model or specification of the bearing, such as 22210, 22312, etc., which should match the actual item. Structure Type: Indicate the bearing structure, such as "double-row spherical roller bearing", "single-row spherical roller bearing", etc. Inner Diameter: Fill in the bearing inner diameter size in millimeters (mm), which should correspond to the model. Outer Diameter: Fill in the bearing outer diameter size in millimeters (mm) to confirm the specification. Material: Fill in the material of the bearing rings and rollers, such as "bearing steel", "stainless steel", etc. Use: Fill in the main application field of the bearing, such as "for motors", "for mining machinery", etc. Product Name: Spherical roller bearing; Brand: SKF; Model: 22210 E; Structure Type: Double-row spherical roller bearing; Inner Diameter: 50mm; Outer Diameter: 90mm; Material: Bearing steel; Use: For industrial fans. Misreporting spherical roller bearings as ball bearings (848210), leading to classification errors. Incomplete model entry, such as writing only 22210 without indicating the variant code, affecting inspection. Using inches as the unit for inner and outer diameters without converting to millimeters, causing data mismatch.

The core basis for classification is the roller shape and self-aligning function of the bearing. Spherical roller bearings have spherical rollers and can self-align, usually of double-row construction. According to HS notes, subheading 848230 specifically refers to this type of bearing. If the rollers are cylindrical or conical, they are classified under other subheadings. 848210 Ball bearings: Ball bearings use spherical balls, while spherical roller bearings use spherical rollers; the roller shapes are different. 848220 Tapered roller bearings: Tapered roller bearings have conical rollers, used to bear combined radial and axial loads, and have no self-aligning function. 848240 Needle roller bearings: Needle roller bearings have slender needle-shaped rollers, usually without inner rings, suitable for occasions with limited radial space. 848250 Other cylindrical roller bearings: Cylindrical roller bearings have cylindrical rollers and cannot self-align, differing in structure from spherical roller bearings. 848280 Other rolling bearings: Includes rolling bearings not elsewhere specified, such as combination bearings; spherical roller bearings are specifically named and are not classified here. Confirm whether the rollers are spherical and can self-align. Check whether the bearing is of double-row construction; single-row spherical roller bearings are also classified here. Check whether it contains other types of rollers, such as cylindrical or conical. Confirm whether it is a rolling bearing rather than a plain shaft bearing. Verify that the model matches the actual item to avoid misreporting.

Are spherical roller bearings and self-aligning roller bearings the same thing? Yes, spherical roller bearings are also commonly called self-aligning roller bearings because their rollers are spherical and can self-align, compensating for misalignment between the shaft and bearing housing. In HS classification, both are classified under 848230. How can I check the tariff rate for 848230? You can check the latest import tariff rate, VAT rate, and regulatory conditions by entering HS code 848230 on the official website of the General Administration of Customs, China International Trade Single Window, or professional tariff query platforms. Tariff rates change, so it is recommended to refer to the latest official publication. When declaring, is the model of the spherical roller bearing required? Yes, the model is an important declaration element that helps customs confirm the commodity specification and classification. The complete model should be filled in, such as 22210 E, avoiding writing only part of the numbers. If the bearing is used for automobiles, are there special classification rules? If an automotive bearing is a rolling bearing, it is still classified under 8482, but note that automotive parts have a dedicated heading (such as 8708); however, bearings are usually not classified under 8708 unless they are assemblies. It is recommended to judge based on actual function. Does the packaging method of spherical roller bearings affect classification? The packaging method does not affect classification; classification depends on the structure and type of the bearing itself. However, when declaring, the packaging type must be truthfully filled in, such as "boxed", "palletized", etc. How should imported used spherical roller bearings be declared? Used bearings must be marked as "used" and may involve solid waste regulation. A test report may be required to prove they can continue to be used. When declaring, elements such as product name and model still need to be complete. What is the main difference between 848230 and 848250? 848230 is spherical roller bearings, with spherical rollers that can self-align; 848250 is other cylindrical roller bearings, with cylindrical rollers that cannot self-align. The difference lies in the roller shape and self-aligning function. For cross-border e-commerce retail export of bearings, is HS code declaration required? Yes, cross-border e-commerce exports also require HS code declaration for customs statistics and regulation. 848230 applies to spherical roller bearings and should be accurately declared to avoid order rejection due to classification errors.
