Import Tips
• Provide mill test certificate confirming alloy composition meets 'other alloy steel' definition per Chapter 72 notes, excluding tool or high-strength steel specs
• Measure and declare exact diameter (14-19mm); mismeasurement leads to reclassification and penalties
• Ensure coils are irregularly wound, not straight lengths, to avoid Chapter 72 heading 72.24
