Products classified under HTS 6903.90.00.10
Clay Refractory Nozzle
Refractory clay nozzle for steel continuous casting, enduring extreme molten metal temperatures. Fired from special refractory clays, it fits HTS 6903.90.00.10 as an 'other' refractory ceramic good explicitly listed as nozzles.
Clay Refractory Tube
High-temperature clay tubes for kiln furniture and thermocouple sheaths. Fired refractory clay construction places it under HTS 6903.90.00.10 as listed 'tubes' other than siliceous types.
Clay Refractory Kiln Shelf
Heavy-duty clay shelves for supporting pottery in industrial kilns. As 'supports' explicitly mentioned in heading 6903, pure clay versions fall under statistical reporting number 6903.90.00.10.
Clay Retort for Laboratory
Traditional clay retorts used in chemical distillation processes at high temperatures. Fired clay construction qualifies as refractory goods under 6903.90.00.10 per heading examples.
Clay Refractory Rod
Fired clay rods used as stirring tools and supports in high-temperature furnaces. As named 'rods' in heading 6903 other refractory goods, clay composition dictates 6903.90.00.10.
Clay Cupel for Assay
Small clay cupels used in precious metal fire assaying to collect beads. Traditional fired clay construction fits 6903.90.00.10 as explicitly named refractory goods.
Clay Refractory Pipe
Heavy clay refractory pipes for high-temperature gas transport in furnaces. Listed as 'pipes' in 6903, clay material specifies 6903.90.00.10 reporting.
Clay Refractory Crucible
A high-temperature clay crucible used for melting metals in foundries and laboratories. It is shaped from refractory clay and fired above 800°C, qualifying as a refractory ceramic good under HTS 6903.90.00.10 due to its clay composition and non-siliceous earth material.
Clay Slide Gate Refractory
Slide gate plates made of refractory clay for controlling molten steel flow in ladles. Explicitly named in heading 6903, these fired clay products are classified under 6903.90.00.10 for clay composition.
Clay Refractory Plug
Refractory clay plugs for sealing furnace ports and ladle openings. Listed as 'plugs' in heading 6903, clay versions report under 6903.90.00.10.
