Import Tips & Compliance
• Confirm the granule size distribution to ensure it meets the definition of 'granular or powder forms' under Chapter Note 1(c)
• Include the alloy's chemical composition on the commercial invoice to avoid delays
• Verify whether the granules are considered 'agglomerated' as this may affect classification
