Forged Alloy Steel Pipe Coupling 2-inch NPT from China
A threaded sleeve coupling made from low-alloy steel like AISI 4140, designed to join two 2-inch nominal pipe size threaded pipes end-to-end. It falls under HTS 7307.92.3030 as a threaded sleeve of alloy steel (not stainless), used in high-pressure plumbing and industrial piping systems. The alloy composition provides enhanced strength and corrosion resistance compared to carbon steel.

Import Tips
• Verify alloy steel composition via mill test certificate to confirm exclusion of stainless steel and qualify under this subheading
• Include detailed technical specs like pressure rating and thread standard (NPT/BSP) in commercial invoice to avoid misclassification as unthreaded fittings
