Chapter 85 covers electric motors, electrical equipment and parts thereof; sound recorders and reproducers, television image and sound recorders and reproducers, and parts and accessories of such articles. This chapter is one of the most technology-intensive chapters in the HS classification, covering a wide range from household appliances to industrial electronic components. Fixed resistors, as basic electronic components, are classified in this chapter due to their functions in circuits such as current limiting, voltage division, and biasing. Heading 8533 covers resistors (including rheostats and potentiometers), but excludes heating resistors. Specifically, it includes fixed resistors, variable resistors, potentiometers, and parts of resistors. Resistors under this heading are generally used in electronic circuits, not as heating elements. Fixed resistors with a power rating greater than 20W are high-power resistors, commonly used in power supplies, industrial control, and similar applications. First 2 digits 85: indicates Chapter 85, electric motors, electrical equipment and parts thereof. Digits 3-4 33: indicates heading 8533, resistors (including rheostats and potentiometers), excluding heating resistors. Digits 5-6 29: indicates subheading 853329, other fixed resistors (power rating greater than 20W). This subheading is further subdivided into fixed resistors with a power rating exceeding 20 watts. Note that 853321 is for fixed resistors with a power rating not exceeding 20W, while 853329 covers fixed resistors with a power rating greater than 20W. The product is a fixed resistor with a power rating greater than 20W, so it is classified under 853329. If the power rating does not exceed 20W, it would be classified under 853321; if it is a variable resistor or potentiometer, it would be classified under 853331 to 853340; if it is a heating resistor, it would be classified under 8516. Therefore, the power rating parameter is the key to distinguishing 853321 from 853329.

🎯 Classification Logic
The core criteria for classification are: 1. Whether the product is a fixed resistor; 2. Whether the rated power is greater than 20W. Only when both conditions are met is it classified under 853329. If the power does not exceed 20W, it is classified under 853321; if it is a variable resistor, it is classified under 853331-853340; if it is a heating resistor, it is classified under 8516. 853321 Other fixed resistors (power rating not exceeding 20W): Different power parameter: 853321 power ≤20W, 853329 power >20W. 853331 Wirewound variable resistors (power rating not exceeding 20W): 853331 is a variable resistor, 853329 is a fixed resistor. 853339 Other variable resistors (power rating greater than 20W): 853339 is a variable resistor, 853329 is a fixed resistor. 851680 Heating resistors: 851680 is a heating resistor, 853329 is a fixed resistor for circuits. Is it a fixed resistor? Is the rated power greater than 20W? Is it used in circuits rather than for heating? Have power and resistance been declared? Is it distinguished from variable resistors?

❓ FAQ
How to inquire about the tax rate for HS code 853329? You can inquire through the official website of the General Administration of Customs, the International Trade Single Window, or professional classification platforms. Note that tax rates are subject to policy adjustments, and it is recommended to refer to the latest published rates. Which code does a fixed resistor with exactly 20W power fall under? Fixed resistors with a power rating not exceeding 20W are classified under 853321, so 20W should be classified under 853321. Only greater than 20W is classified under 853329. How to distinguish between fixed resistors and variable resistors? Fixed resistors have a fixed resistance value that cannot be adjusted; variable resistors have adjustable resistance. According to HS codes, fixed resistors are classified under 853321/853329, and variable resistors under 853331-853340. Can heating resistors be classified under 853329? No. Heating resistors are classified under 8516, such as heating wires, heating tubes, etc. 853329 only applies to fixed resistors for circuits. What are the consequences of filling in the wrong power unit during declaration? It may lead to incorrect classification, thereby affecting tax rates and regulatory conditions, and even be deemed as false declaration by customs, facing penalties. What are the common types of resistors under 853329? Common types include wirewound resistors, metal film resistors, cement resistors, etc., with power greater than 20W, used in power supplies, industrial control, etc. If the resistor has no brand, how to fill in during declaration? If there is no brand, fill in "no brand"; it cannot be left blank. At the same time, the model must be filled in for identification. What other factors need to be considered during classification? In addition to power and type, factors such as purpose and material also need to be considered. But the core is fixed resistor and power greater than 20W.
