## What this code covers

HS code 8542.31 covers electronic integrated circuits, processors and controllers, whether or not combined with memories, converters, logic circuits, amplifiers, clock and timing circuits, or other circuits.

The legal text of the subheading is “Electronic integrated circuits: Processors and controllers, whether or not combined with memories, converters, logic circuits, amplifiers, clock and timing circuits, or other circuits”, read under “Electronic integrated circuits”, in HS2022.

## What it doesn’t cover

Other goods of heading 85.42 are classified under 8542.32 (electronic integrated circuits, memories), 8542.33 (electronic integrated circuits, amplifiers), 8542.39 (electronic integrated circuits, other) or 8542.90 (parts).

- [8542.32](https://staging.border.bot/hs-codes/854232) Electronic integrated circuits: Memories
- [8542.33](https://staging.border.bot/hs-codes/854233) Electronic integrated circuits: Amplifiers
- [8542.39](https://staging.border.bot/hs-codes/854239) Electronic integrated circuits: Other
- [8542.90](https://staging.border.bot/hs-codes/854290) Parts

## How it is structured

8542.31 is a six-digit subheading. Its first two digits, 85, are the chapter; the first four, 8542, are heading 85.42; the last two, 31, 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 85.42: Electronic integrated circuits
- Within the heading: Electronic integrated circuits
- Subheading 8542.31: Processors and controllers, whether or not combined with memories, converters, logic circuits, amplifiers, clock and timing circuits, or other circuits

## In other countries

No national tariff lines under 8542.31 are live on border.bot yet. Tariffs built on the Harmonized System (HS2022) use 8542.31 at six digits and add their own digits after it.
