Products classified under HTS 7306.29.60.50
2-3/8 Inch EUE Tubing
Externally upset end (EUE) tubing, 2-3/8 inch diameter, made of non-alloy steel for oil and gas production strings. HTS 7306.29.6050 covers this as other tubing for drilling applications. Threads allow connection in well completions.
Gas Well Liner Tubing
Non-alloy steel welded liner tubing for gas well completions, extending casing. Under HTS 7306.29.6050 as other tubing for gas drilling. Hanger systems compatible.
Intermediate Casing Tubing
Welded non-alloy intermediate casing tubing for multi-stage oil well construction. HTS 7306.29.6050 covers other nonalloy steel for drilling. Bridges surface and production casing.
P110 High Yield Tubing
P110 grade high-yield strength non-alloy steel tubing for deep oil/gas wells, welded profile. HTS 7306.29.6050 for other nonalloy drilling tubing. Withstands extreme pressures in HPHT wells.
API 5CT N80 Casing Tubing
Seamless or welded steel tubing made from non-alloy steel, conforming to API 5CT specifications for N80 grade, used as casing and tubing in oil and gas drilling operations. It falls under HTS 7306.29.6050 as 'other' tubing of iron or nonalloy steel for drilling purposes, excluding certain specialized types. The tubing supports wellbore stability and fluid extraction in upstream oilfield applications.
J55 Grade Oil Well Tubing
Welded non-alloy steel tubing in J55 grade per API standards, designed for production tubing in oil wells to convey hydrocarbons. Classified under HTS 7306.29.6050 as other iron/nonalloy steel tubing for oil/gas drilling. It provides structural integrity during extraction phases.
K55 Casing and Tubing
K55 grade non-alloy steel tubing used interchangeably as casing or tubing in shallow oil/gas wells. Falls under HTS 7306.29.6050 for other nonalloy steel tubing in drilling. Offers higher collapse resistance for challenging environments.
L80 Type 1 Production Tubing
L80 Type 1 non-alloy steel tubing for production in corrosive oil/gas environments, welded construction. Classified in HTS 7306.29.6050 as other tubing for drilling ops. Provides martensitic structure for durability.
4-1/2 Inch Welded Drill Tubing
4-1/2 inch OD welded non-alloy steel tubing for intermediate casing and production in gas wells. HTS 7306.29.6050 applies to this other category for oil/gas drilling tubing. Designed for high-pressure environments.
Non-API Standard Oilfield Tubing
Custom non-alloy steel welded tubing for oilfield drilling, not meeting full API 5CT but used similarly for casing/tubing. Covered by HTS 7306.29.6050 as other iron/nonalloy steel tubing. Tailored for specific well geometries.
