Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

3920.99.20.00Lower: 39.2% vs 53.5%

If imported as generic plastic sheets without battery-specific design

Plain polyethylene sheets without microporous structure or battery end-use features fall under noncellular plastics plates.

8507.90.80.00Lower: 53.4% vs 53.5%

If for parts of other battery types like nickel-metal hydride

Parts must be specifically designed for lead-acid; others go to the general battery parts subheading.

Import Tips & Compliance

• Verify material composition (e.g

• polyethylene, AGM) matches lead-acid battery specifications to avoid reclassification

• Include technical datasheets proving compatibility with lead-acid cells; declare as parts, not complete batteries

• Check for hazardous material declarations due to potential chemical residues from manufacturing
