Analysis

NAICS 325414 is the 2022 national industry for biological product (except diagnostic) manufacturing, part of 32541 (Pharmaceutical and Medicine Manufacturing). Census lists 22 example activities under it in the official index.

Between 2018 and 2023 the number of establishments grew 22% and employment rose 34%. 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 441 US establishments in this code in 2023, employing 75,198 people at an average annual payroll of $125,302 per employee (93rd percentile of national industries). 28% of the establishments have fewer than five employees, which is close to the national mix.

Its index entries, the activities Census uses to assign businesses to this code, include agar culture media manufacturing, aggressins (except in-vitro) manufacturing, allergenic extracts (except diagnostic substances)… and allergens manufacturing, among 22 in all.

Its goods appear in 18 statistical lines of the US tariff schedule, mostly under headings 3002 (human blood; animal blood prepared for therapeutic…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.

For example, manufacturing in-vitro diagnostic substances are classified in 325413 (In-Vitro Diagnostic Substance Manufacturing) instead.
