## What this code covers

HS code 6902.10 covers refractory bricks, blocks, tiles and similar refractory ceramic constructional goods, other than those of siliceous fossil meals or similar siliceous earths, containing by weight, singly or together, more than 50 % of the elements Mg, Ca or Cr, expressed as MgO, CaO or Cr2O3.

The legal text of the subheading is “Containing by weight, singly or together, more than 50 % of the elements Mg, Ca or Cr, expressed as MgO, CaO or Cr2O3”, in HS2022.

## What it doesn’t cover

Other goods of heading 69.02 are classified under 6902.20 (containing, by weight, more than 50 % of alumina (Al2O3), of silica (SiO2) or of a mixture or compound of these products) or 6902.90 (other).

- [6902.20](https://staging.border.bot/hs-codes/690220) Containing, by weight, more than 50 % of alumina (Al2O3), of silica (SiO2) or of a mixture or compound of these products
- [6902.90](https://staging.border.bot/hs-codes/690290) Other

## How it is structured

6902.10 is a six-digit subheading. Its first two digits, 69, are the chapter; the first four, 6902, are heading 69.02; the last two, 10, identify the subheading within the heading.

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

- Chapter 69: Ceramic products
- Heading 69.02: Refractory bricks, blocks, tiles and similar refractory ceramic constructional goods, other than those of siliceous fossil meals or similar siliceous earths
- Subheading 6902.10: Containing by weight, singly or together, more than 50 % of the elements Mg, Ca or Cr, expressed as MgO, CaO or Cr2O3

## In other countries

No national tariff lines under 6902.10 are live on border.bot yet. Tariffs built on the Harmonized System (HS2022) use 6902.10 at six digits and add their own digits after it.

- Previous subheading: [6901.00](https://staging.border.bot/hs-codes/690100) Bricks, blocks, tiles and other ceramic goods of siliceous fossil meals (for example, kieselguhr, tripolite or diatomite) or of similar siliceous earths
- Next subheading: [6902.20](https://staging.border.bot/hs-codes/690220) Containing, by weight, more than 50 % of alumina (Al2O3), of silica (SiO2) or of a mixture or compound of these products
