Parts of Nonelectric Industrial or Laboratory Furnaces, Ovens & Incinerators

Refractory bricks and shapes are generally classified under Chapter 69 (ceramic products) when imported separately, not under 841790. However, pre-assembled refractory modules or panels specifically designed and shaped for a particular furnace model may qualify as parts under 841790. The degree of specificity to the furnace and whether the item is presented as a furnace part or as a raw refractory product determines classification.

India has a well-developed foundry and refractory manufacturing industry that produces cast iron and steel components, heat-resistant castings, and refractory products at competitive cost. These capabilities align closely with the types of replacement parts — grate bars, combustion chamber liners, and structural castings — that dominate import volumes under this heading.
