8547.10.80.00 - Other

HTS code 8547.10.80.00 encompasses "Other" insulating fittings of ceramics used for electrical machinery, appliances, or equipment. This classification is for ceramic insulating fittings that do not fall under the more specific subcategory for ceramic insulators intended for spark plugs in natural gas-fueled, stationary, internal combustion engines (8547.10.40.00). Therefore, this residual category captures a broad range of ceramic insulating parts, such as bushings, sockets, standoffs, and other shaped ceramic components, which are exclusively made of insulating material except for minor metal elements integrated for assembly purposes.

The distinction from its sibling category is critical: 8547.10.40.00 is precisely defined for insulators used in a particular application (spark plugs for specific engine types). If a ceramic insulating fitting is not designed or intended for that specific spark plug application, it will fall under this "Other" classification. This implies that 8547.10.80.00 is a residual category for all other ceramic insulating fittings that serve the broader purpose of insulating electrical components, machinery, appliances, and equipment.

As this is a leaf node, there are no further subdivisions under 8547.10.80.00. Classification within this code relies on identifying ceramic insulating fittings that are not otherwise specified and are intended for use in electrical applications as described by the parent heading 8547. The key criteria for inclusion are the material (wholly of ceramic, with minor metal assembly aids) and the function (insulating electrical machinery, appliances, or equipment), provided they are not specifically classified elsewhere.
