How it is structured
2830.90 is a six-digit subheading. Its first two digits, 28, are the chapter; the first four, 2830, are heading 28.30; the last two, 90, identify the subheading within the heading.
Countries add their own digits after these six for their national tariff lines.
In other countries
No national tariff lines under 2830.90 are live on border.bot yet. Tariffs built on the Harmonized System (HS2022) use 2830.90 at six digits and add their own digits after it.
