Refractory bricks, blocks, tiles and similar refractory ceramic constructional goods, other than those of siliceous fossil meals or similar siliceous earths
10 declarable lines
Heading 6902 covers refractory ceramic constructional goods such as bricks, blocks, tiles and similar shapes that resist high heat, but not goods made of siliceous fossil meals or similar siliceous earths. It splits first by chemistry: goods with more than 50% magnesium, calcium or chromium oxides (6902.10), goods with more than 50% alumina, silica or a mix of them (6902.20), and everything else (6902.90). Each of those is then split by whether the article is a brick or another shape, and in the residual line by whether the material is clay or other.
Products in this heading
- Magnesite bricks for steel furnace linings
- High alumina kiln bricks for cement kilns
- Silica bricks for coke oven walls
- Fireclay refractory bricks for boiler and fireplace linings
- Chrome-magnesite refractory blocks for ladle linings
- Refractory shapes and tiles used to line kilns and incinerators
How to choose the right subheading
- Whether the goods contain, singly or together, more than 50% magnesium, calcium or chromium expressed as MgO, CaO or Cr2O3, which leads to 6902.10.
- Whether the goods contain more than 50% alumina, silica, or a mixture of the two, which leads to 6902.20.
- Whether the article is a brick or block rather than another shape such as a tile, which decides between the brick and other lines inside a subheading.
- For goods in the residual 6902.90 lines, whether the material is clay or another ceramic substance.
- Whether the goods are made of siliceous fossil meals or similar siliceous earths, in which case heading 6902 does not apply.
Often confused with
- Heading 6904Ordinary ceramic building bricks
Not heat resisting; building bricks sit in the constructional brick heading.
- Heading 6905Ceramic roofing tiles and chimney pots
Constructional ceramic goods that are not refractory.
- Heading 6907Ceramic floor and wall tiles
Paving, hearth and wall tiles are classified there even if sold for hearth use.
- Heading 6903Refractory crucibles, retorts and nozzles
Refractory goods other than bricks, blocks and tiles are in 6903.
- Heading 6911Ceramic or porcelain tableware
Household tableware is not a refractory constructional good.
Frequently asked questions
What is the HTS code for magnesite refractory bricks?
Magnesite bricks containing more than 50% magnesium, calcium or chromium oxides are classified under 6902.10.10.00, with a general (MFN) rate of Free.
What is the duty on alumina refractory bricks?
Alumina bricks with more than 50% alumina fall under 6902.20.10.10, and the general (MFN) rate is Free. Other bricks in that subheading use 6902.20.10.20, also Free.
How do I classify fireclay refractory bricks?
Clay refractory bricks that do not meet the magnesium, calcium, chromium, alumina or silica thresholds are classified under 6902.90.10.10, at a general (MFN) rate of Free. Non-brick clay shapes in the same residual group go to 6902.90.50.10, also Free.
