Products classified under HTS 7304.19.10

API 5L Grade B Seamless Line Pipe

This seamless steel tube, made from nonalloy steel, is specifically designed for oil and gas pipeline applications, meeting API 5L Grade B specifications for strength and durability. It falls under HTS 7304.19.10 as line pipe of iron or nonalloy steel, distinct from welded pipes in other headings. The seamless construction ensures high pressure resistance without welds.

12-Inch OD Seamless Oil Pipeline Tube

A 12-inch outer diameter seamless pipe of nonalloy steel, engineered for transporting crude oil in pipelines. Classified under HTS 7304.19.10 due to its seamless manufacture and designation as line pipe for oil/gas transport. It meets industry standards for corrosion resistance in long-distance applications.

X42 Seamless Gas Transmission Pipe

Seamless nonalloy steel pipe rated X42 per API standards, used for natural gas transmission lines. It qualifies for HTS 7304.19.10 as 'other' line pipe of iron/nonalloy steel for oil or gas pipelines. The high yield strength supports buried or subsea installations.

16-Inch Seamless Carbon Steel Line Pipe

Heavy-duty 16-inch seamless carbon (nonalloy) steel pipe for offshore oil/gas gathering lines. HTS 7304.19.10 applies as seamless line pipe not of cast iron, optimized for high-pressure hydrocarbon transport. Corrosion coatings are often applied post-import.

Grade B 10-Inch OD Pipeline Tube

10-inch OD Grade B seamless tube of nonalloy steel for midstream oil/gas pipelines. Falls under HTS 7304.19.10 for its role in long-haul transport, distinct from downstream or upstream tubulars. Designed for easy coupling in field installations.

PSL1 Seamless Oil Line Pipe

PSL1 (Product Specification Level 1) seamless nonalloy steel pipe for crude oil lines, compliant with API 5L. HTS 7304.19.10 covers this as other seamless line pipe of iron/nonalloy steel for pipelines. Suitable for sour service environments.

20-Inch Diameter Gas Line Pipe

Large 20-inch seamless nonalloy steel pipe for high-volume natural gas transmission mains. Classified in HTS 7304.19.10 as line pipe for gas pipelines, with thick walls for burial under highways. Exceeds typical drill pipe dimensions.

Carbon Steel Sour Service Line Pipe

Seamless carbon steel pipe resistant to H2S in sour oil/gas service, API 5L compliant. HTS 7304.19.10 for nonalloy seamless line pipe used in corrosive pipeline environments. Chemistry controlled for sulfide stress cracking.
