## How it is structured

8430.31 is a six-digit subheading. Its first two digits, 84, are the chapter; the first four, 8430, are heading 84.30; the last two, 31, identify the subheading within the heading.

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

- Chapter 84: Nuclear reactors, boilers, machinery and mechanical appliances; parts thereof
- Heading 84.30: Other moving, grading, levelling, scraping, excavating, tamping, compacting, extracting or boring machinery, for earth, minerals or ores; pile-drivers and pile-extractors; snow-ploughs and snow- blowers
- Within the heading: Coal or rock cutters and tunnelling machinery
- Subheading 8430.31: Self-propelled

## In other countries

No national tariff lines under 8430.31 are live on border.bot yet. Tariffs built on the Harmonized System (HS2022) use 8430.31 at six digits and add their own digits after it.

- Previous subheading: [8430.20](https://staging.border.bot/hs-codes/843020) Snow-ploughs and snow-blowers
- Next subheading: [8430.39](https://staging.border.bot/hs-codes/843039) Coal or rock cutters and tunnelling machinery: Other
