Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the substrate is assembled with a resistive element and terminations
A complete fixed resistor would fall under this heading rather than as a part.
If the substrate is a bare aluminum part without any resistor-specific features
General aluminum articles are classified in Chapter 76 if not identifiable as resistor parts.

Import Tips & Compliance
• Confirm the substrate is not a complete resistor; if it includes resistive elements and terminations, it may be classified as a complete resistor
• Provide documentation showing the anodization process and material composition for CBSA review
• Ensure the goods are properly marked with country of origin to avoid delays at the border
