Last updated: August 2026 dataFlexible tubing fabricated from base metals other than iron or steel — most commonly aluminum, copper, or brass — serves precision fluid-handling, instrumentation, and specialty industrial applications where corrosion resistance or weight savings are priorities. The US schedule mirrors the iron/steel heading by splitting on fittings: with fittings (8307903000) and without fittings (8307906000). Israel leads US imports under this heading, followed by Mexico and Canada; Mexico and Canada qualify for USMCA preferential treatment, which can meaningfully reduce landed cost relative to other origins.

Aluminum, copper, brass, and nickel alloys are the most commercially common non-ferrous base metals used in flexible tubing under this heading. The specific metal affects corrosion resistance, pressure ratings, and end-use suitability, but does not create separate HTS subdivisions within 830790 — all non-iron, non-steel base metal flexible tubing falls under the same heading.
To claim USMCA preferential treatment, the importer must possess a valid certification of origin from the producer or exporter at the time of entry. The certification must confirm that the tubing meets the applicable tariff shift or regional value content rule under USMCA Annex 4-B. CBP may request supporting production records during a post-entry audit.
