Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If generic metal caps/stoppers
Metal caps without electrical terminals or hermetic specs are stoppers/caps.
If copper-based screw caps
Copper alloy end caps without terminals may classify as copper articles.
If aluminum capacitor housings
Aluminum cases complete with seals may be capacitor housings vs parts.

Import Tips & Compliance
• Leak rate specifications (<10^-9 cc/sec helium) prove hermetic seal function for classification
• Include pressure rating and electrolyte compatibility data in import documentation
• Avoid classification as general metal stampings (8309.90) with capacitor-specific engineering drawings
