## How it is structured

3102.60 is a six-digit subheading. Its first two digits, 31, are the chapter; the first four, 3102, are heading 31.02; the last two, 60, identify the subheading within the heading.

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

- Chapter 31: Fertilisers
- Heading 31.02: Mineral or chemical fertilisers, nitrogenous
- Subheading 3102.60: Double salts and mixtures of calcium nitrate and ammonium nitrate

## In other countries

No national tariff lines under 3102.60 are live on border.bot yet. Tariffs built on the Harmonized System (HS2022) use 3102.60 at six digits and add their own digits after it.

- Previous subheading: [3102.50](https://staging.border.bot/hs-codes/310250) Sodium nitrate
- Next subheading: [3102.80](https://staging.border.bot/hs-codes/310280) Mixtures of urea and ammonium nitrate in aqueous or ammoniacal solution
