This code covers stainless steel drill pipe used in oil and gas drilling. It’s used for classifying these specific pipes when importing into the U.S., and generally benefits from free duty under standard trade agreements or eligible preference programs, as detailed within Chapter 73.

HTS media

This duty schedule covers articles of iron or steel within Chapter 73, specifically focusing on seamless tubes and pipes used in oil or gas drilling. The 7304.22.00 code identifies drill pipe made of stainless steel, which is a key component in these drilling operations. Further classification depends on the pipe’s dimensions: choose 7304.22.00.30 for pipes under 168.3 mm in diameter with wall thickness not exceeding 9.5 mm, 7304.22.00.45 for those under 168.3 mm with wall thickness exceeding 9.5 mm, or 7304.22.00.60 for those exceeding 168.3 mm in diameter.
