Dear Mr. Hasegawa: In your letter dated July 12, 1996 you requested a tariff classification ruling. The Noritake Roller Hearth Kilns (RHK) use many independent ceramic rotating rollers to move the product to be fired through the kiln. The inside of the kiln is made from refractories and ceramic materials for high firing temperature.
