4.5 Inch OD Stainless Steel Oilfield Tubing
Seamless stainless steel tubing with an outside diameter of 4.5 inches (114.3 mm), designed specifically for use as casing and tubing in oil and gas drilling operations. This product falls under HTS 7304.24.60.45 due to its seamless construction, stainless steel material, and size range exceeding 114.3 mm but less than 215.9 mm, tailored for downhole applications in harsh environments.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If welded rather than seamless
Welded stainless steel pipes for oil/gas use fall under 7306, as seamlessness is key for 7304 classification.
If made of carbon steel instead of stainless
Carbon steel seamless casing/tubing shifts to 7304.41, as stainless steel specifies the 7304.24 subheading.
If for smaller diameters under 114.3 mm
Tubing with OD ≤114.3 mm is classified in 7304.29 statistical suffixes, based on precise size thresholds.

Import Tips & Compliance
• Verify API 5CT certification and provide mill test reports (MTRs) to confirm seamless stainless steel composition and compliance with oilfield standards
• Ensure accurate measurement of outside diameter to avoid misclassification; common pitfall is confusing with welded pipes under Chapter 73 headings
• Declare end-use as oil/gas drilling explicitly to prevent reclassification as general mechanical tubing
