Import Tips
• Provide alloy breakdown (e.g
• C36000 brass) to confirm copper content over 50% for Chapter 84 classification
• Test reports for pressure ratings are critical; mismatches lead to 10% MFN duty reassessment
• Avoid bulk packaging misclassification—retail sets may trigger 8481.80.90 if not purely individual valves
