Import Tips

Verify copper alloy composition meets HTS copper definition (over 97% copper) with mill test certificates

Include pressure rating certification from manufacturer to confirm 850 kPa threshold during customs entry

Avoid misclassification as ball valves; provide engineering drawings showing plug mechanism
