Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If designed for molding rubber or plastics
Molds for rubber or plastics fall under separate subheading regardless of semiconductor use.
If classified as part of testing apparatus
Semiconductor testing equipment parts may shift to Chapter 90 provisions.
If for machines not exclusively molding
Multi-function semiconductor machines without primary molding function go to other machines.
