Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not specifically for electrical insulation or assembly
Plain plastic grommets without electrical insulating function or metal inserts for assembly fall under general plastic articles in Chapter 39.
If primarily metal conduit with plastic lining
Fittings classified as base metal electrical conduit tubing lined with insulating material go to heading 7307, not insulating fittings.
If designed as electrical insulators for overhead power lines
Insulators of heading 8546 are specifically for supporting or insulating electrical conductors in transmission lines, distinguished by voltage rating and design.

Import Tips & Compliance
• Verify the fittings are wholly of insulating material (90%+ non-conductive) with only minor metal components for assembly to qualify under 8547
• Provide detailed engineering drawings showing material specs and metal content to avoid reclassification as metal conduit fittings
