Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If constructed with ceramic tube instead of glass
Ceramic cartridge fuses fall under the separate subheading for non-glass materials in the fuses category.
If for higher voltage applications exceeding 1,000V
Fuses designed for voltages over 1,000V shift to heading 8536.50, regardless of glass construction.
If sold as complete fuse assemblies with holders or bases
When imported as parts of larger electrical apparatus with mounting hardware, classification moves to heading 8538 for assemblies.
