Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If machined for bolt hole patterns
Bolt hole drilling constitutes 'tooled' processing.
If high-alloy steel variants
Alloy content determines shift to 7307.99 series.
If imported with tank or reservoir fittings
Set assemblies for containers reclassify as Chapter 73 tank accessories.
