2-7/8" T95 Alloy Steel Production Tubing
Seamless T95 alloy tubing (73 mm OD, 8.0 mm wall) used as production casing in oil wells post-drilling. Although termed 'tubing,' meets casing definition under HTS 7304.29.41.10 for seamless alloy steel drilling pipes with specified dimensions. Collapse-resistant design for sustained production.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If strictly production tubing not used in drilling phase
Post-drilling production tubing may classify under 7306 if not meeting casing specs.
If wall thickness 12.7 mm or greater
Thicker wall casing uses separate statistical reporting number.
If imported as plain-end unfinished pipe
Plain-end unfinished seamless pipe falls outside specific casing provisions.

Import Tips & Compliance
• Differentiate from true tubing (7306.20); drilling/production use governs 7304 classification
• Batch certificates must specify 'casing/tubing, drilling applications' to prevent misclassification
• Beware valuation disputes; related-party transactions require arm's-length pricing documentation
