Importers of Zinc, Unwrought (Not Alloyed) paid $454K in duties in August 2026, an average duty rate of 0.19% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Zinc, Unwrought (Not Alloyed) imports of $234.0M in August 2026 ran 30% above the year-to-date monthly average of $179.6M.
Last updated: August 2026 dataUnalloyed zinc in unwrought form — ingots, slabs, and jumbo blocks — is the primary feedstock for hot-dip galvanizing operations that protect steel in construction, automotive, and infrastructure applications. Special High Grade (SHG) zinc, defined by a minimum purity of 99.995% Zn, is the benchmark traded on the London Metal Exchange and the standard specification for most galvanizing and die-casting alloy production. Trade flows for unalloyed unwrought zinc are sensitive to global steel output levels, since galvanizing demand tracks steel production closely.

Special High Grade (SHG, minimum 99.995% Zn) is the dominant traded grade and the LME delivery standard. High Grade (HG, minimum 99.95%) and Prime Western (PW, minimum 98%) are lower-purity grades used in specific alloy or chemical applications. Shipments should be accompanied by a producer's certificate of analysis confirming zinc content and key impurity levels (lead, cadmium, iron) to support classification and buyer acceptance.
Unalloyed zinc (this heading) covers metal that is essentially pure zinc without intentional alloying additions. Once antimony, aluminum, copper, or other elements are deliberately added to create a zinc alloy, the product shifts to the zinc alloys heading. The boundary matters for duty and statistical purposes, and the certificate of analysis is the key document for establishing which category applies.
