Import Tips

• Provide thread type (e.g

• LTC, STC) details and hydrostatic test certificates for customs clearance

• Label shipments clearly as 'oil well casing' to distinguish from general tubing and avoid reclassification

• Monitor steel alloy content certificates to confirm nonalloy status under HTS definitions
