Analysis

NAICS 331315 is the 2022 national industry for aluminum sheet, plate, and foil manufacturing, part of 33131 (Alumina and Aluminum Production and Processing). Census lists 20 example activities under it in the official index.

County Business Patterns counts 80 US establishments in this code in 2023, employing 18,025 people at an average annual payroll of $97,588 per employee (83rd percentile of national industries). 15% of the establishments have fewer than five employees, which points to larger operations.

Between 2018 and 2023 the number of establishments fell 16% and employment fell 9%. 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.

Its index entries, the activities Census uses to assign businesses to this code, include aluminum foil made by flat rolling purchased aluminum, aluminum foil made in integrated secondary smelting and…, aluminum plate made by continuous casting purchased aluminum and aluminum plate made by flat rolling purchased aluminum, among 20 in all.

Its goods appear in 25 statistical lines of the US tariff schedule, mostly under headings 7606 (aluminum plates, sheets and strip, of a thickness exceeding…) and 7607 (aluminum foil (whether or not printed, or backed with…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.

For example, making aluminum from alumina and flat rolling or continuous casting aluminum sheet, plate, foil, and welded tube are classified in 331313 (Alumina Refining and Primary Aluminum Production) instead.
