NAICS 327212

Overview

The North American Industry Classification System (NAICS) is the federal statistical standard for classifying business establishments to support the collection, analysis, and publication of data on the U.S. economy. Developed under the auspices of the Office of Management and Budget and adopted in 1997, NAICS is maintained jointly with Statistics Canada and Mexico’s INEGI; the current site supports the 2022 NAICS structure. ¹

NAICS 327212 covers establishments that manufacture glass by melting silica sand or cullet and then press, blow, or otherwise shape the glass into glassware or other non-container products. It is used in federal statistics and as a reference point in solicitations to distinguish primary glassmaking of non-container items from related industries such as flat glass, container glass, and products made from purchased glass. ²

What this NAICS covers

• Pressed glassware produced from in-house melted batch (silica sand or cullet). ²
• Blown glassware formed from in-house melted glass (non-container items). ²
• Shaped and formed specialty glass products (excluding packaging containers) made in integrated glassmaking operations. ²
• Production of molded glass lens blanks referenced from optical and ophthalmic cross-industries. ³
• Manufacture of glass blanks for electric light bulbs and tubes. ²
• Industrial and laboratory non-container glass items made by pressing, blowing, or shaping from a melt. ²

Frequently asked questions

• What is included in NAICS 327212?

  • Establishments that melt silica sand or cullet and then press, blow, or shape the glass into non-container glassware or specialty items are included. This category explicitly excludes glass packaging containers. ²

• How does NAICS 327212 differ from NAICS 327215?

  • NAICS 327212 requires primary glassmaking from a melt; NAICS 327215 covers making glass products from purchased glass (remelting or shaping), not melting batch to make new glass. ²

• Are bottles and jars included in NAICS 327212?

• Do molded glass lens blanks belong in NAICS 327212?

  • Yes. Cross-references indicate molded glass lens blanks are classified in NAICS 327212; finished optical instruments and lens manufacturing are classified elsewhere. ³

• Does NAICS 327212 cover fiber optic cable or fiberglass insulation?

  • No. Fiber optic cable manufacturing is NAICS 335921, and mineral wool (fiberglass) insulation is NAICS 327993. ²
