Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If after machining into specific semiconductor components
Machined or shaped rods become 'worked' under chapter note exclusions.
If classified as semiconductor manufacturing machine parts
Finished rods designed solely for wafer processing equipment fall under Chapter 84/85.
If chemically treated for dopant diffusion
Surface-coated or chemically prepared glass shifts to prepared chemical products.
