Import Tips
• Ensure the material is not considered waste or scrap under Chapter 26 Note 1(f) — if it is used principally for precious metal recovery, heading 71.12 may apply
• Document the reprocessing steps to show the material is an ore or concentrate
• Verify that the silver content meets the statistical reporting threshold
