332710: Machine Shops

What this code covers

Census puts a shop in 332710 when its main business is machining metal, plastic, or composite parts to order, one job at a time. Runs tend to be small. The work is done on lathes, mills, grinders, and machining centers, and the shop usually has no product line of its own.

For defense and aerospace work that means milled housings and brackets, turned shafts and pins, bushings, manifolds, fixtures, and spares made from a government drawing. Many shops also deburr, mark, and do light assembly on the same order. High-volume screw machine work has its own code, 332721.

What federal buyers typically ask for

Most notices under this code are build-to-print. DLA posts a steady flow of small quantity requests on DIBBS for spare parts, usually with a technical data package in cFolders. Depots and shipyards post larger one-off jobs. NASA centers and test ranges post fixture and ground support work.

Expect first article inspection on a new part number, a certificate of conformance with each shipment, and material certs traced to the heat lot. Steel, titanium, and nickel alloy parts usually carry the DFARS specialty metals clause. Many drawings are export controlled, so you need a Joint Certification Program registration to download them. Critical safety items require source approval before your quote counts.

Total small business set-asides are common on the small buys. HUBZone, service-disabled veteran, and woman-owned set-asides appear less often. Larger unrestricted buys still go to small shops regularly.
