NAICS 332613

Overview

The North American Industry Classification System (NAICS) is the standard taxonomy U.S. federal statistical programs use to classify business establishments for economic data collection, analysis, and publication. Developed under the Office of Management and Budget and adopted in 1997, NAICS is jointly maintained with Statistics Canada and Mexico’s INEGI; the current U.S. vintage is 2022 and is being phased into federal economic programs through 2027. ¹

NAICS 332613 — Spring Manufacturing — is defined in the 2017 NAICS as establishments primarily engaged in manufacturing metal springs from purchased wire, strip, or rod. Cross-references clarify that watch and clock springs fall under 334519, wire drawing belongs to Subsector 331, and insulating nonferrous wire is classified in 33592. ²

What this NAICS covers

• Manufacture of compression, extension, and torsion coil springs from purchased wire. ²
• Production of flat and leaf springs formed from strip or rod stock. ²
• Custom precision springs for industrial, aerospace, and transportation uses (from purchased wire/strip/rod). ²
• Heat forming and finishing operations integral to spring fabrication. ²
• Spring sets/assemblies when made as spring products (not broader vehicle suspension systems). ²
• Replacement and OEM metal springs manufactured from purchased materials. ²

2022 NAICS revision note

• Under 2017 NAICS, spring manufacturing is represented by 332613 “Spring Manufacturing.” ²
• In 2022 NAICS materials, spring manufacturing detail appears under 332611 (Heavy Gauge) and 332612 (Light Gauge). ⁴

Frequently asked questions

• What does NAICS 332613 include?
  Establishments primarily engaged in making metal springs from purchased wire, strip, or rod, including coil and flat/leaf types. The NAICS manual provides cross-references to avoid misclassification, such as watch and clock springs and wire drawing activities. ²

• Is 332613 still used in 2022-vintage data?
  The 2022 NAICS vintage restructured spring manufacturing into 332611 and 332612. Federal statistical programs are transitioning to 2022 NAICS through 2027, so legacy 2017 codes may appear in historical series during the phase-in. ¹

• Which PSC most closely aligns for supply buys of springs?
  PSC 5360 covers “Coil, Flat, and Wire Springs,” aligning with commodity spring purchases that establishments in 332613 produce. For services or assemblies beyond discrete springs, other PSCs may apply based on scope. ³

• Are wire forms without a spring function classified in 332613?
  No. Fabricated wire products that are not springs are generally classified in 332618, which covers other fabricated wire products. Establishments that both draw wire and fabricate are classified in Subsector 331. ²

• Where are watch and clock springs classified?
  Watch and clock springs are excluded from 332613 and placed in 334519, which covers measuring and controlling device manufacturing, including timekeeping devices. ²
