HS-4 · Heading
Chapter 69: Ceramic products
Use HS-4 6902 when importing refractory bricks, blocks, tiles, or similar construction goods made from ceramic materials. For instance, if you're shipping a batch of high-temperature resistant bricks for industrial furnaces, this heading is applicable.
When deciding between HS-6 lines, consider the material composition. If your product contains more than 50% magnesium, calcium, or chromium, use HS-6 690210. If it has over 50% alumina or silica, then HS-6 690220 is the right choice.
For products that do not fit neatly into the first two categories, such as those with mixed compositions or lower percentages of the specified elements, you would classify them under HS-6 690290. This line captures all other refractory ceramic goods not covered by the first two subheadings.
