API 5CT J55 Casing Tubing 2-3/8 Inch OD 10.2 lb/ft
Seamless steel tubing made from J55 grade nonalloy steel for oil and gas well casing and production tubing. Features an outside diameter of 60.3 mm (2-3/8 inches) and wall thickness of 11.0 mm, exceeding 9.5 mm, used to line boreholes and transport hydrocarbons. Classified under 7304.29.5030 due to its seamless construction, nonalloy steel material, and specifications for drilling applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alloy steel composition exceeding specified limits
Alloy steel tubing (e.g., with Cr, Mo > specified thresholds) shifts to 7304.29.10 subheading regardless of wall thickness.
If not specifically for oil/gas drilling end-use
General seamless steel tubes not designed as casing/tubing for drilling classify under Chapter 73 heading 7306 for other hollow profiles.
If welded rather than seamless construction
Welded (not seamless) oilfield tubing falls under 7304.39, as seamlessness is a key criterion for 7304.2x headings.

Import Tips & Compliance
• Verify API 5CT certification and provide mill test reports (MTRs) confirming seamless production, chemical composition, and mechanical properties
• Ensure accurate measurement documentation for OD ≤114.3mm and wall thickness >9.5mm to avoid reclassification to thinner wall subheadings
• Comply with API Monogram or equivalent standards; common pitfall is incorrect country-of-melt declaration for steel origin rules
