NAICS 327110

Overview

The North American Industry Classification System (NAICS) is the production-oriented taxonomy used by U.S. federal statistical programs to categorize establishments and publish economic statistics. Developed under the Office of Management and Budget and adopted in 1997, NAICS is updated every five years; current Census economic statistics are published on the 2022 NAICS vintage. ¹

NAICS 327110 — Pottery, Ceramics, and Plumbing Fixture Manufacturing — covers establishments primarily engaged in shaping, molding, glazing, and firing pottery, ceramics, and plumbing fixtures made wholly or partly of clay or other ceramic materials. Federal datasets use this industry to tabulate outputs spanning ceramic tableware, decorative items, and vitreous china sanitary ware, distinct from plastic or metal fixture manufacturing. ²

Industry boundaries and common exclusions

• Enameled iron or steel plumbing fixtures are classified under fabricated metal product manufacturing, not this ceramic industry. ²
• Plastic bathroom accessories and cultured‑marble or other plastic plumbing fixtures fall under NAICS 326191, not 327110. ²
• Clay building materials (e.g., ceramic tile, bricks, roofing tile) and refractories are outside this NAICS; they are treated as clay building material and refractories manufacturing. ²

Frequently asked questions

• What products are included in NAICS 327110? Included products span vitreous china plumbing fixtures, ceramic bathroom accessories, table and kitchen articles (porcelain, stoneware, earthenware), art and ornamental pottery, and chemical stoneware. The scope centers on ceramic materials that are shaped, glazed, and fired. ²

• What activities are specifically excluded from 327110? Plastic plumbing fixtures and bathroom accessories map to NAICS 326191. Enameled iron or steel sanitary ware is treated under fabricated metal product manufacturing (e.g., 3329xx in prior vintages), and clay building materials/refractories are elsewhere. ²

• How does NAICS 2022 affect use of 327110 in federal data? Census programs began publishing detailed industry statistics on the 2022 NAICS basis with the 2022 Economic Census, and remaining programs are transitioning through 2027. This ensures pottery/ceramics/plumbing fixture outputs are consistently measured under the updated code. ³

• Which PSCs commonly pair with procurements under 327110? PSCs selected at the line‑item level often include 4510 Plumbing Fixtures and Accessories, 4540 Miscellaneous Plumbing, Heating, and Sanitation Equipment, and 7350 Tableware, depending on the deliverable. ⁴
