Import Tips

• Include detailed grade certificates (e.g

• K-55 per API 5CT) and thread type specs in entry docs to confirm drilling casing use

• Measure wall thickness precisely post-manufacture; even slight under 12.7 mm risks duty rate change or penalties

• Comply with Buy America provisions if for US projects; source documentation prevents customs holds
