Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If high tantalum content
Significant precious metal content may trigger Chapter 71 classification.
If narrower clad bars/plates
<600mm width clad products remain in 7212 clad provisions.
If ceramic lined
Alternative corrosion protection methods use different material chapters.
