Last updated: August 2026 dataIron and steel flexible tubing — used in fluid conveyance, electrical conduit, and mechanical protection applications across industrial, HVAC, and automotive sectors — is split at the 10-digit level by whether fittings are included: with fittings (8307103000) and without fittings (8307106000). Chinese-origin goods are subject to Section 232 tariffs on steel mill products as well as potential Section 301 exposure, making India and Mexico increasingly attractive alternative sources. The with/without fittings distinction affects both classification and valuation, so importers should ensure fittings are itemized separately when sold as discrete components.

If fittings are imported separately or invoiced as discrete components, each part should be classified independently. CBP's essential character analysis and GRI 3 apply when the classification is ambiguous.
