Last updated: July 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 the tubing and fittings are imported together as a functional assembly and the fittings are integral to the article's commercial identity, the complete assembly classifies under 8307103000. 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.
Yes. Flexible tubing of iron or steel may be subject to Section 232 tariffs depending on origin and product specifications. Importers should confirm applicability with a licensed customs broker, as exclusions and country-specific arrangements under Section 232 have changed over time.
