Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If static converter parts
Transformer internal components imported assembled classify under 8504 rather than separate fittings.
If other insulating fittings
Non-ceramic spacers (composite/plastic) fall under the general 'other' insulating fittings subheading.
If carbon-based spacers
Carbon or graphite spacers classify under Chapter 68 articles of stone/plaster.
