NAICS 332117

Overview

The North American Industry Classification System (NAICS) is the federal standard for categorizing business establishments to enable consistent collection, analysis, and publication of statistics about the U.S. economy. Developed under the Office of Management and Budget (OMB) with Canada and Mexico and adopted in 1997 for cross-country comparability, the latest revision cycle in use is the 2022 NAICS. ²

NAICS 332117 (Powder Metallurgy Part Manufacturing) covers establishments primarily engaged in producing powder metallurgy products by compacting metal powders in shaped dies and sintering, typically manufacturing a wide range of parts on a job or order basis. This industry sits within the Fabricated Metal Product Manufacturing subsector and the Forging and Stamping industry group. ¹

What this NAICS covers

• Manufacturing of powder metallurgy products via compaction in a shaped die. ¹
• Sintering of compacted parts to achieve final material properties. ¹
• Job- or order-based production of a wide range of metal parts. ¹
• Placement within Fabricated Metal Product Manufacturing (332) and the Forging and Stamping group (3321). ¹
• Excludes integrated primary metal operations classified in Primary Metal Manufacturing (331). ¹
• Excludes automotive stampings, which are classified under Motor Vehicle Metal Stamping (336370). ¹

Scope and classification notes

• Powder metallurgy part manufacturing is grouped with forging, roll forming, and stamping under the Forging and Stamping industry group (3321). ¹
• Work that both makes primary metals and produces parts in an integrated process is classified to Primary Metal Manufacturing (331), not 332117. ¹
• Automotive stampings are outside 332117 and classified under 336370. ¹

Frequently asked questions

• What activities define NAICS 332117?

  • Establishments manufacture powder metallurgy products by compacting metal powders in shaped dies and sintering, usually producing a wide range of parts on a job or order basis. ¹

• Is metal injection molding (MIM) explicitly included in 332117?

  • Not specified by official sources. The NAICS definition references compaction in a shaped die and sintering; it does not enumerate specific powder-metallurgy techniques beyond this description. ¹

• How does 332117 differ from forging or stamping codes?

  • Forging (332111, 332112) and stamping (332119) use distinct processes on purchased metal, whereas 332117 forms parts from metal powders by compaction and sintering. ¹

• Does 332117 cover metal 3D printing/additive manufacturing using powders?

  • Not specified by official sources. The published definition is limited to compaction in a shaped die and sintering. ¹

• Where are official statistics for 332117 published?

  • The 2022 Economic Census publishes Manufacturing statistics on the 2022 NAICS basis; users can access sector tables and filter to 332117 on data.census.gov or via Manufacturing sector resources. ⁴
