Other Nonferrous Metals

Section 301 tariffs apply to a range of goods originating from China, and several specialty nonferrous metals and their intermediate forms — including certain cobalt compounds, tungsten products, and molybdenum articles — have been listed in Section 301 annexes. Because coverage is determined at the HTS subheading level and has been modified through multiple rounds of review, importers should verify current applicability for each specific product and origin with a licensed customs broker.

Titanium sponge — the primary reduced form produced from titanium tetrachloride — is classified under HTS Chapter 81 as unwrought titanium, while rolled sheet, plate, bar, and tube are classified as wrought or semi-manufactured forms in the same chapter but under distinct subheadings. The distinction affects duty rates and, for defense-related applications, may trigger domestic sourcing requirements under the Berry Amendment.
