# HS code 8533.90: Parts

> HS code 8533.90 covers parts. 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), 8533.21 (other fixed resistors, for a power handling capacity not exceeding 20 W), 8533.29 (other fixed resistors, other), 8533.31 (wirewound variable resistors, including rheostats and potentiometers, for a power handling capacity not exceeding 20 W) or 2 others. National tariff lines under 8533.90 are live on border.bot for the United States (2 lines, also used by 1 other country).

## How it is structured

8533.90 is a six-digit subheading. Its first two digits, 85, are the chapter; the first four, 8533, are heading 85.33; the last two, 90, identify the subheading within the heading.

Countries add their own digits after these six for their national tariff lines.
