Analysis
NAICS 331210 is the 2022 national industry for iron and steel pipe and tube manufacturing from purchased steel, part of 33121 (Iron and Steel Pipe and Tube Manufacturing from Purchased Steel). Census lists 6 example activities under it in the official index.
County Business Patterns counts 294 US establishments in this code in 2023, employing 27,433 people at an average annual payroll of $87,092 per employee (75th percentile of national industries). 17% of the establishments have fewer than five employees, which points to larger operations.
Its index entries, the activities Census uses to assign businesses to this code, include boiler tubes, wrought, made from purchased iron, conduit, welded and lock joint, made from purchased iron or…, pipe (e.g., heavy riveted, lock joint, seamless, welded)… and tube (e.g., heavy riveted, lock joint, seamless, welded)…, among 6 in all.
Its goods appear in 2 statistical lines of the US tariff schedule, mostly under headings 7305 (other tubes and pipes (for example, welded, riveted or…) and 7306 (other tubes, pipes and hollow profiles (for example, open…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
For example, making steel and further processing the steel into steel pipe and tube are classified in 331110 (Iron and Steel Mills and Ferroalloy Manufacturing) instead.
Between 2018 and 2023 the number of establishments grew 5% and employment rose 6%. 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.
