How it is structured
3822.90 is a six-digit subheading. Its first two digits, 38, are the chapter; the first four, 3822, are heading 38.22; the last two, 90, identify the subheading within the heading.
Countries add their own digits after these six for their national tariff lines.
- Chapter 38
- Miscellaneous chemical products
- Subheading 3822.90
- Other
In other countries
No national tariff lines under 3822.90 are live on border.bot yet. Tariffs built on the Harmonized System (HS2022) use 3822.90 at six digits and add their own digits after it.
