Products classified under HTS 7304.29.10.20
API 5CT L-80 Type 9 Casing Pipe
Seamless L-80 Type 9 casing pipe made from nonalloy steel, threaded and coupled, with an outside diameter of 177.8 mm and wall thickness of 14.2 mm, designed for oil and gas well drilling. It falls under HTS 7304.29.10.20 due to its seamless construction, nonalloy steel material, specific diameter less than 215.9 mm, and thick wall exceeding 12.7 mm for high-pressure environments. This classification ensures accurate duty assessment for drilling casings.
7-inch J-55 Threaded Casing Tube
Seamless J-55 grade casing with 7-inch (177.8 mm) OD, 15.9 mm wall thickness, threaded ends and couplings, constructed from nonalloy steel for oil well casing strings. Classified under HTS 7304.29.10.20 for its seamless iron/nonalloy steel build, drilling-specific use, OD under 215.9 mm, and robust wall thickness ≥12.7 mm. Ideal for intermediate casing in drilling operations.
4.5-inch N-80 Casing Pipe
Seamless N-80 nonalloy steel casing pipe, 4.5-inch (114.3 mm) OD, 13.5 mm wall thickness, with premium threaded connections and couplings for deep oil/gas wells. HTS 7304.29.10.20 applies due to seamless construction, nonalloy material, drilling casing purpose, sub-215.9 mm diameter, and thick walls for structural integrity. Used primarily in production casing applications.
