U.S. imports of Secondary Aluminum Smelting & Alloying (NAICS 331314) totaled $8.1M in August 2026, imported from 19 countries.
Importers of Secondary Aluminum Smelting & Alloying paid $1.1M in duties in August 2026, an average duty rate of 14.01% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataRecovered and recycled aluminum scrap is re-melted and alloyed in secondary smelting operations classified under NAICS 331314, producing alloy ingots and billets that feed casting and fabrication industries. Secondary aluminum is commercially significant in automotive, aerospace, and packaging supply chains, where recycled-content specifications are increasingly mandated by OEM procurement standards. Because secondary aluminum originates from scrap rather than primary smelting, classification and origin documentation can be more complex, particularly when mixed-origin scrap is processed domestically or abroad before import.

The HTS distinguishes unwrought aluminum alloys (which include most secondary aluminum output) from unalloyed primary aluminum based on alloy composition thresholds. Secondary smelters typically produce alloy ingots with defined silicon, copper, or magnesium content, and the specific alloy designation determines the correct 10-digit HTS subheading and applicable duty treatment.
Yes, Section 232 tariffs generally apply to aluminum articles including alloy ingots, regardless of whether they originate from primary or secondary smelting. Country-specific exemptions and quota arrangements may apply, so importers should verify the current status for each supplier country before entry.
