Analysis
NAICS 331314 is the 2022 national industry for secondary smelting and alloying of aluminum, part of 33131 (Alumina and Aluminum Production and Processing). Census lists 16 example activities under it in the official index.
County Business Patterns counts 92 US establishments in this code in 2023, employing 5,746 people at an average annual payroll of $78,209 per employee (67th percentile of national industries). 11% of the establishments have fewer than five employees, which points to larger operations.
Census lists 5 related activities that belong elsewhere, most often in 331313, 331315, 331318 and 423930. Businesses that do several things are classified by their primary activity, the one that generates the most value, so check those boundaries before settling on this code.
Its index entries, the activities Census uses to assign businesses to this code, include alloying purchased aluminum metals, aluminum alloys made from scrap or dross, aluminum billet made from purchased aluminum and aluminum billet made in integrated secondary smelting and…, among 16 in all.
Its goods appear in 4 statistical lines of the US tariff schedule, mostly under headings 7601 (unwrought aluminum) and 7603 (aluminum powders and flakes). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
For example, refining alumina or making aluminum and/or aluminum alloys from alumina are classified in 331313 (Alumina Refining and Primary Aluminum Production) instead.
Official definition
This U.S. industry comprises establishments primarily engaged in (1) recovering aluminum and aluminum alloys from scrap and/or dross (i.e., secondary smelting) and making billet or ingot (except by rolling) and/or (2) manufacturing alloys, powder, paste, or flake from purchased aluminum.
