U.S. imports of secondary aluminum smelting & alloying (NAICS 331314) totaled $9.8M in April 2026, traded with 14 countries.
Importers of Secondary Aluminum Smelting & Alloying paid $1.3M in duties in April 2026 — an effective duty rate of 14% on $9.3M in dutiable value, based on actual customs collections rather than the published tariff schedule. Secondary Aluminum Smelting & Alloying imports of $9.8M in April 2026 ran 42% above the year-to-date monthly average of $6.9M.
Last updated: April 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.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
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.
