8547.90.00.10 - Other insulating fittings

This HTS category, 8547.90.00.10, encompasses "Other insulating fittings." These are components primarily made of insulating material, designed for use with electrical machinery, appliances, or equipment. While they may incorporate minor metal elements, these are solely for assembly purposes, such as threaded sockets integrated during the molding process. This classification excludes complete insulators specifically covered by heading 8546.

The distinction between this category and its sibling lies in their fundamental construction and purpose. The sibling category, "Electrical conduit tubing and joints therefor, of base metal lined with insulating material," specifically refers to tubes and their connecting pieces where the primary structure is base metal, with an insulating lining. In contrast, 8547.90.00.10 covers fittings where the insulating material is the dominant component, not merely a lining within a metal structure.

As this HTS code represents a leaf node, there are no further subcategories. Therefore, classification within 8547.90.00.10 relies on a thorough assessment of the item's construction, ensuring it meets the definition of an insulating fitting and is not specifically provided for elsewhere in Chapter 85, particularly under heading 8546. Practical examples would include various insulating bases, supports, or connectors used within electrical enclosures or devices, provided they are predominantly of insulating material.
