What is NAICS 3321

NAICS code 3321 covers the forging and stamping industry, which includes establishments engaged in shaping metal by applying compressive forces, either through forging or stamping processes. This sector plays a critical role in manufacturing durable metal components by deforming metal billets or sheets into specific shapes, often used in automotive, aerospace, defense, and industrial machinery applications. Businesses operating in this sector range from small job shops specializing in custom metal forming to large-scale manufacturers producing high-volume metal parts with precision and repeatability. Government agencies contract for these services to procure reliable, high-strength metal parts essential for mission-critical equipment, infrastructure, and defense systems, where metal integrity and performance are paramount.

Government Buyers for NAICS 3321

Government agencies such as the Department of Defense (DoD), the Department of Transportation (DOT), and the General Services Administration (GSA) are typical buyers of forging and stamping services. These agencies require robust metal components for military vehicles, aircraft, naval vessels, and transportation infrastructure. Additionally, agencies involved in energy, such as the Department of Energy (DOE), may procure forged or stamped metal parts for power generation equipment and industrial machinery. The need for durable, high-quality metal components in government projects drives demand for reliable forging and stamping contractors.

Contract Types & Procurement for NAICS 3321

Contracts in the forging and stamping sector commonly include firm-fixed-price, indefinite delivery/indefinite quantity (IDIQ), and cost-reimbursement types, depending on the complexity and volume of parts required. Procurement methods often involve competitive bidding, request for quotations (RFQs), and solicitations through government contracting portals such as SAM.gov. Contract values vary widely, from small orders of custom forgings for prototype development to large multi-year contracts for high-volume production of standardized metal components, typically ranging from tens of thousands to several million dollars.
