API 5L Grade B Carbon Steel Line Pipe 16-inch OD
This is a welded carbon steel line pipe conforming to API 5L Grade B specifications, designed specifically for oil and gas pipelines with an outside diameter of 16 inches (406.4 mm), exceeding 114.3 mm. It falls under HTS 7306.19.1050 as it is of iron or nonalloy steel, classified as line pipe for pipelines rather than casing or tubing. The pipe is hot-formed and welded, suitable for transporting crude oil or natural gas under pressure.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If intended for use as casing or tubing in oil/gas wells
Line pipe for pipelines is 7306, but pipes primarily for well drilling or extraction are classified under Chapter 73 heading 7304 as oil well tubing.
If made of stainless steel instead of nonalloy steel
Material composition determines heading; stainless steel line pipe over 114.3 mm OD falls under 7306.30, not 7306.19 for iron/nonalloy.
If outside diameter is 114.3 mm or less
Size threshold splits classification; smaller OD line pipe of nonalloy steel is in 7306.19.16, while exceeding 114.3 mm is 7306.19.10.

Import Tips & Compliance
• Verify API 5L certification and mill test reports (MTRs) to confirm nonalloy steel composition and ensure compliance with pipeline standards
• Include detailed documentation on outside diameter measurement and weld type (e.g
• submerged arc welded) to avoid misclassification
