# HS code 8533.21: Other fixed resistors, for a power handling capacity not exceeding 20 W > HS code 8533.21 covers other fixed resistors, for a power handling capacity not exceeding 20 W. It sits in heading 85.33 (electrical resistors (including rheostats and potentiometers), other than heating resistors) in chapter 85 (electrical machinery and equipment and parts thereof; sound recorders and reproducers, television image and sound recorders and reproducers, and parts and accessories of such articles). Other goods of heading 85.33 are classified under 8533.10 (fixed carbon resistors, composition or film types), 8533.29 (other fixed resistors, other), 8533.31 (wirewound variable resistors, including rheostats and potentiometers, for a power handling capacity not exceeding 20 W), 8533.39 (wirewound variable resistors, including rheostats and potentiometers, other) or 2 others. National tariff lines under 8533.21 are live on border.bot for the United States (9 lines, also used by 1 other country).

The legal text of the subheading is “Other fixed resistors: For a power handling capacity not exceeding 20 W”, read under “Other fixed resistors”, in HS2022. ## What it doesn’t cover Other goods of heading 85.33 are classified under 8533.10 (fixed carbon resistors, composition or film types), 8533.29 (other fixed resistors, other), 8533.31 (wirewound variable resistors, including rheostats and potentiometers, for a power handling capacity not exceeding 20 W), 8533.39 (wirewound variable resistors, including rheostats and potentiometers, other) or 2 others. - [8533.10](https://border.bot/hs-codes/853310) Fixed carbon resistors, composition or film types - [8533.29](https://border.bot/hs-codes/853329) Other fixed resistors: Other - [8533.31](https://border.bot/hs-codes/853331) Wirewound variable resistors, including rheostats and potentiometers: For a power handling capacity not exceeding 20 W - [8533.39](https://border.bot/hs-codes/853339) Wirewound variable resistors, including rheostats and potentiometers: Other - [8533.40](https://border.bot/hs-codes/853340) Other variable resistors, including rheostats and potentiometers - [8533.90](https://border.bot/hs-codes/853390) Parts ## How it is structured 8533.21 is a six-digit subheading. Its first two digits, 85, are the chapter; the first four, 8533, are heading 85.33; the last two, 21, identify the subheading within the heading. Countries add their own digits after these six for their national tariff lines. - Chapter 85: Electrical machinery and equipment and parts thereof; sound recorders and reproducers, television image and sound recorders and reproducers, and parts and accessories of such articles - Heading 85.33: Electrical resistors (including rheostats and potentiometers), other than heating resistors - Within the heading: Other fixed resistors - Subheading 8533.21: For a power handling capacity not exceeding 20 W ## In other countries National tariff lines under 8533.21 are live on border.bot for the United States (9 lines, also used by 1 other country). - [United States](https://border.bot/countries/united-states/hs-codes/853321): 9 lines, used by 1 other country - Previous subheading: [8533.10](https://border.bot/hs-codes/853310) Fixed carbon resistors, composition or film types - Next subheading: [8533.29](https://border.bot/hs-codes/853329) Other fixed resistors: Other ## Frequently asked questions ### What does HS code 8533.21 cover?
