Import Tips

Verify exact lead percentage via certified assay report to confirm classification within 5-25% range and avoid reclassification to pure tin or higher-lead alloys

Include mill test certificates (MTC) documenting tin predominance (>50% by weight) and compliance with chapter note (b) for tin alloys

Be aware of RoHS restrictions in certain markets; declare lead content accurately to prevent customs holds or penalties
