HS Code 8546
Electrical Insulators of Any Material
HS code 8546 covers electrical insulators made of any material, including glass, ceramic, or plastic, used to support and isolate electrical conductors.
HS Code 8546 — Electrical Insulators of Any Material
This code covers components specifically designed to prevent the flow of electricity between a conductor and its support. These are typically made of glass or ceramic and are used extensively on power lines and in electrical substations.
What's included
- Glass insulators
- Ceramic/Porcelain insulators
- Polymer/Plastic insulators
- Suspension insulators for power lines
- Pin-type insulators
What's excluded
- Insulating fittings for machinery → use
8547(Fittings that also provide structural support or conduit are in 8547.)
Common examples
- Porcelain pole-top insulator
- Glass disc insulator string
- Composite suspension insulator
- Station post insulator
Frequently asked questions
What is the difference between 8546 and 8547?
8546 is for the standalone 'insulator' itself (like a porcelain cap), while 8547 is for 'fittings' designed for insulating machines or conduits.
