Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

7304.49.00Same rate: 35%

If boiler/condenser/superheater specific

Narrower use-specification for steam generation equipment triggers dedicated subheadings.

8421.39.01Same rate: 35%

If integral to incineration equipment

Machinery-specific tubes become parts of filtering/purifying equipment in Chapter 84.
