Import Tips

• Verify core material composition (e.g

• grain-oriented silicon steel) via mill test certificates to confirm HTS classification and avoid reclassification as iron articles

• Ensure documentation specifies 'stacked for transformer incorporation' to distinguish from finished cores; include end-use statements for transformer manufacturers

• Watch for weight-based valuation pitfalls; stacked cores often ship in bulk—declare net weight accurately to prevent duty underpayment claims
