Import Tips
• Verify cermet composition certification from manufacturer to confirm HTS 8533.40.80.50 classification and avoid reclassification to fixed resistors
• Include detailed technical specs and resistance value declarations in commercial invoice to prevent valuation disputes
• Ensure RoHS compliance documentation, as electronics importers often face scrutiny on hazardous substances
