How it is structured
8405.90 is a six-digit subheading. Its first two digits, 84, are the chapter; the first four, 8405, are heading 84.05; 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 8405.90 are live on border.bot yet. Tariffs built on the Harmonized System (HS2022) use 8405.90 at six digits and add their own digits after it.
