3321 - Forging and Stamping

Understanding the NAICS code system is essential for businesses and government contractors seeking to categorize their activities accurately. One critical NAICS code in the manufacturing sector is NAICS 3321 - Forging and Stamping. This industry plays a vital role in producing metal parts through advanced metal forming processes, supporting various sectors like automotive, aerospace, and heavy machinery.

What is NAICS Code 3321 - Forging and Stamping?

NAICS Code 3321 covers establishments primarily engaged in forging, stamping, and related metal forming processes. These processes involve shaping metal materials by applying force through hot or cold forging, stamping, and pressing techniques to create metal parts and products essential for countless manufacturing applications.

Key Processes Under NAICS 3321:

• Hot forging: Shaping heated metal to improve strength and structural integrity.
• Cold forging: Deforming metal at room temperature for precision parts.
• Stamping: Pressing metal sheets into specific shapes and sizes.
• Pressing: Applying pressure to form metal components.

Sector: Manufacturing

NAICS 3321 falls under the Manufacturing sector, which includes businesses focused on transforming raw materials into finished goods. Forging and stamping operations are foundational within manufacturing, providing critical components for larger assembly products.

Typical Business Activities Under NAICS 3321

Businesses classified under this NAICS code typically engage in:

• Metal forging (both open-die and closed-die forging)
• Metal stamping and pressing operations
• Production of forged metal parts such as gears, shafts, and fittings
• Manufacturing specialized metal components for vehicles, machinery, and industrial equipment

Examples of Business Types:

• Metal forging companies specializing in industrial components
• Stamping and pressing shops producing sheet metal parts
• Manufacturers of custom-forged metal parts for aerospace and defense industries

Size Standards for NAICS 3321 Eligibility

For government contracting and small business certifications, the Small Business Administration (SBA) defines size standards based on employee count and annual revenue. Under NAICS 3321:

• Small business size standard: Typically 1,250 employees or less
• Varies depending on the specific sub-industry and goods produced

Businesses must verify their size status based on the latest SBA guidelines to qualify for small business programs and contracts.

Frequently Asked Questions (FAQ)

What industries rely on NAICS 3321 forging and stamping services?

Industries like automotive manufacturing, aerospace, defense, heavy machinery, and construction frequently use forged and stamped metal parts for durable, precision components.

Can small businesses qualify under NAICS 3321 for government contracts?

Yes, many small forging and stamping companies qualify provided they meet the SBA size standards (typically fewer than 1,250 employees). They can benefit from small business contracting programs.

What is the difference between forging and stamping?

• Forging involves shaping metal by applying compressive forces using dies and hammers, often at high temperatures.
• Stamping uses specialized dies and presses to cut or shape metal sheets, usually at room temperature.

How does NAICS 3321 relate to other manufacturing codes?

NAICS 3321 specifically focuses on metal forming through forging and stamping. Other NAICS codes, like 336 for transportation equipment manufacturing, may utilize parts produced under 3321.
