Import Tips

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
