Chapter 84 is the core chapter in the HS classification system covering machinery, mechanical appliances, and their parts, including power machinery, pumps, compressors, bearings, gears, transmission devices, etc. Goods in this chapter typically function for power transmission, motion conversion, or mechanical energy utilization, and are an important component of mechanical and electrical products in international trade. Heading 8483 covers transmission shafts, cranks, bearing housings, plain shaft bearings, gears, friction wheels, flywheels, pulleys, clutches, universal joints, and other transmission devices and parts. These goods are used to support rotating parts, transmit power, or change motion modes, and are indispensable basic components in mechanical equipment. The first 2 digits 84 represent Chapter 84 (machinery and mechanical appliances and parts thereof); digits 3-4, 83, represent heading 8483 (transmission shafts, bearing housings, gears, and other transmission devices); digits 5-6, 20, represent subheading 848320, specifically bearing housings incorporating ball or roller bearings. Bearing housings under this subheading usually have rolling bearings built in and are used to directly support shafts and bear loads, differing from bearing housings without bearings (classified under 848330) or plain shaft bearings (classified under 848330). This commodity is a bearing housing incorporating ball or roller bearings, whose core function is to support rotating shafts and bear radial or axial loads. Because it has an integrated rolling bearing, it is not a bearing housing without bearings (848330), nor is it a separate rolling bearing (848210-848280), so classification under 848320 is the most accurate.

Product name: Declare the Chinese and English names of the commodity, which should be consistent with the actual goods, such as "轴承座 Bearing housing". Use: Explain the application scenario of the bearing housing, such as shaft support for motors, pumps, fans, transmission devices, etc. Brand: Fill in the manufacturer or brand name; if there is no brand, fill in "no brand". Model: Fill in the specific model or specification code of the product to facilitate identification and classification. Whether equipped with ball or roller bearings: Clearly answer "yes" or "no"; this is the key element for classification under 848320. Bearing type: If bearings are installed, indicate whether they are ball bearings or roller bearings, and the specific type (such as deep groove ball bearings, tapered roller bearings). Material: Fill in the material of the bearing housing body, such as cast iron, cast steel, aluminum alloy, etc. Dimensions: Provide key dimensional parameters such as inner diameter, outer diameter, and width to facilitate specification verification. Product name: Bearing housing; Use: For centrifugal pump shaft support; Brand: SKF; Model: SY 50 TF; Whether equipped with ball or roller bearings: Yes; Bearing type: Deep groove ball bearing; Material: Cast iron; Dimensions: Inner diameter 50mm, outer diameter 120mm, width 45mm. Failure to specify whether bearings are installed, leading to incorrect classification under 848330. Confusing the bearing housing with the bearing itself, incorrectly classifying under 8482. Ignoring material declaration, affecting customs valuation and classification. False model entry, resulting in inability to match during inspection.

The core basis for classification is whether the commodity is equipped with ball or roller bearings. If the bearing housing has an integrated rolling bearing, it is classified under 848320; if no bearing is installed, it is classified under 848330 (bearing housings, not incorporating bearings); if it is a plain shaft bearing, it is also classified under 848330. In addition, it is necessary to confirm whether the bearing housing is dedicated to a certain machine. If it is a dedicated part of a certain machine, it may be classified according to the complete machine, but usually bearing housings are classified under 8483 as general-purpose parts. 848330 Bearing housings (not incorporating bearings): 848330 is for bearing housings not incorporating ball or roller bearings, while 848320 must already incorporate rolling bearings. 848210 Ball bearings: 848210 is a separate ball bearing without a bearing housing; 848320 is a combination of a bearing and a bearing housing. 848250 Other cylindrical roller bearings: 848250 is a separate cylindrical roller bearing, while 848320 is a bearing housing incorporating such bearings. 848790 Other machinery parts: 848790 is for machinery parts not elsewhere specified; this code is considered only if the bearing housing does not incorporate bearings and is not classified under 848330. Is it equipped with ball or roller bearings? Is the bearing type ball or roller? Is it dedicated to a certain type of machine? Are the material and dimensions fully declared? Do the brand and model match the actual item?

What is the difference between a bearing housing and a bearing? Are the HS codes different? A bearing is an independent rotating part, classified under 8482; a bearing housing is a shell that supports the bearing. If it incorporates a bearing, it is classified under 848320; if not, under 848330. They have different functions and different codes. How can one determine whether a bearing housing incorporates ball or roller bearings? Check the actual item or drawings. If ball or roller bearings are already installed inside the bearing housing and cannot be easily separated, it is considered incorporated; if it is only an empty shell, it is not incorporated. If a bearing housing is classified under 848320, is it still necessary to declare the brand of the bearing? Yes. If the bearing housing incorporates a bearing, the brand and model of the bearing should be declared so that customs can verify intellectual property and valuation. If a bearing housing is custom-made as a dedicated part for a certain machine, is it still classified under 848320? If the bearing housing is a general-purpose type, it is still classified under 848320; if it is dedicated to a certain machine and constitutes the characteristics of a complete machine, it may be classified according to the complete machine, requiring specific analysis. What is the export tax rebate rate for 848320? The rebate rate is adjusted according to policy. Please consult the latest export tax rebate rate database or consult the local customs. Is a material certificate required when importing bearing housings? Usually not required, but if customs has doubts about the material, it may be requested. It is advisable to keep relevant technical documents. For cross-border e-commerce sales of bearing housings, how to determine the HS code? Based on whether the product incorporates rolling bearings, choose 848320 or 848330. You may refer to the product manual or consult a professional customs broker. What are the differences in declaration elements between 848320 and 848330? 848320 requires declaration of the bearing type (ball or roller), while 848330 does not; both require declaration of material, dimensions, use, etc.
