Import Tips
• Verify the forging certification and material composition (e.g
• high-purity steel) to confirm suitability solely for semiconductor equipment under statistical notes
• Include detailed engineering drawings and end-use statements proving principal use with heading 8426 machinery to avoid misclassification
• Watch for anti-dumping duties on certain steel forgings; declare exact alloy specs to prevent customs holds
