API 5L Grade B Seamless Steel Pipe 4-inch OD 0.5-inch Wall from Germany
A seamless carbon steel pipe with 101.6 mm OD and 12.8 mm wall thickness, made from non-alloy steel for oil and gas transmission lines. It falls under HTS 7304.39.0032 due to its circular cross-section, OD between 38.1-114.3 mm, and wall thickness over 12.7 mm. Commonly used in high-pressure pipelines requiring structural integrity.

Import Tips
• Verify seamless certification via NDT reports (ultrasonic/hydrostatic testing) as required for API 5L specs to avoid reclassification
• Include mill test certificates (MTC) showing chemical composition and mechanical properties for non-alloy steel confirmation
• Measure OD and wall thickness precisely; tolerances under 12.7 mm wall shifts to thinner subheadings, risking underpayment penalties
