Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If steel with zinc plating for HVAC use
Zinc-coated steel duct fittings are under Chapter 73 structures of iron/steel, not zinc articles.
If as parts of air conditioning units
Fittings specifically for AC machinery are classified in Chapter 84 under the complete machine's heading.
If not qualifying as tubes, pipes, or fittings
Other simple zinc castings or forgings fall under the residual 7907.00.60 subheading.
