NAICS 325314

Overview

The North American Industry Classification System (NAICS) is the U.S. federal standard for classifying business establishments to produce comparable statistics on the economy. Developed jointly by the U.S. Economic Classification Policy Committee, Statistics Canada, and Mexico’s INEGI, NAICS replaced SIC in 1997 and the current vintage is 2022. ¹

NAICS 325314 — Fertilizer (Mixing Only) Manufacturing — covers establishments primarily engaged in mixing purchased ingredients into fertilizers. It excludes manufacturers that produce nitrogenous or phosphatic fertilizer materials; those activities are classified in 325311 and 325312, respectively. ²

Frequently asked questions

• What activities define NAICS 325314?

  • Establishments in this industry mix ingredients manufactured elsewhere into fertilizers. The code distinguishes blending/mixing operations from manufacturing base fertilizer materials, which fall under 325311 or 325312. ²

• Does NAICS 325314 include compost?

  • Yes. Official cross-references specify that compost manufacturing is classified in 325314 rather than in waste management and remediation industries. This aligns with the “mixing-only” focus of the code. ²

• How does 325314 differ from 325311 and 325312?

  • 325314 covers mixing-only operations using purchased ingredients. 325311 and 325312 cover establishments that manufacture nitrogenous or phosphatic fertilizer materials (and may also blend them). ²

• Are pesticides part of this NAICS?

  • No. Pesticide and household pest-control chemicals are classified under 325320, not under fertilizer manufacturing. ²

• Which federal statistical programs publish data for 325314?

  • The Economic Census covers the Manufacturing sector (31–33), including fertilizer manufacturing industries such as 325314. The current vintage for NAICS-based tabulations is 2022. ⁵
