Alumina Refractory Kiln Shelf
Alumina refractory kiln shelves are flat, fired ceramic components made predominantly of alumina, used to support pottery during high-temperature kiln firing up to 1800°C. They are designed as constructional parts of kiln interiors to resist thermal shock and chemical attack, meeting the criteria for refractory ceramic constructional goods.

Import Tips & Compliance
• Confirm the shelves are fired at temperatures above 800°C to qualify under Chapter 69
• Keep documentation showing alumina content exceeds 50% by weight
• Check if the shelves are considered constructional goods, as non-constructional refractory articles may fall under a different tariff item
