8 digit HS code
An 8 digit HS code is the United States tariff line, the level at which the rate of duty is set; the table below counts the schedule's numbers by length and says what each length means.
Tariff numbers by digit length
| digits | example | level | lines |
|---|---|---|---|
| 4 | 0101 | heading: the product group every HS member shares | 961 |
| 6 | 0101.90 | subheading: the last level shared worldwide | 2093 |
| 8 | 0101.21.00 | tariff line: where the United States sets the rate of duty | 6857 |
| 10 | 0101.21.00.10 | statistical suffix: the level reported on an entry | 19949 |
Four and six digits are shared with every Harmonized System member; the eight-digit line is national and sets the rate; the tenth digit exists for statistics and is the number reported on an entry.
Methodology
Every numbered line of the current schedule is grouped by the length of its number with the dots removed; the level each length means is stated from the schedule's own structure.
