Analysis
NAICS 331318 is the 2022 national industry for other aluminum rolling, drawing, and extruding, part of 33131 (Alumina and Aluminum Production and Processing). Census lists 55 example activities under it in the official index.
Between 2018 and 2023 the number of establishments fell 16% and employment rose 1%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
County Business Patterns counts 227 US establishments in this code in 2023, employing 30,004 people at an average annual payroll of $60,736 per employee (34th percentile of national industries). 12% of the establishments have fewer than five employees, which points to larger operations.
By establishments it ranks 1st of the 4 codes at this level within Alumina and Aluminum Production and Processing, with 52.7% of them.
Its index entries, the activities Census uses to assign businesses to this code, include aluminum bar made by extruding purchased aluminum, aluminum bar made in integrated secondary smelting and…, aluminum pipe made by extruding purchased aluminum and aluminum pipe made in integrated secondary smelting and…, among 55 in all.
Its goods appear in 29 statistical lines of the US tariff schedule, mostly under headings 7604 (aluminum bars, rods and profiles), 7614 (stranded wire, cables, plaited bands and the like…) and 7605 (aluminum wire). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
Official definition
This U.S. industry comprises establishments primarily engaged in (1) rolling, drawing, or extruding shapes (except flat rolled sheet, plate, foil, and welded tube) from purchased aluminum and/or (2) recovering aluminum from scrap and rolling, drawing, or extruding shapes (except flat rolled sheet, plate, foil, and welded tube) in integrated mills.
