326199: All Other Plastics Product Manufacturing

What this code covers

NAICS 326199 is the residual plastics code. Film and sheet, bags, profile shapes, pipe, laminates, foam, bottles, plumbing fixtures and resilient flooring each have their own code, and everything else made of plastic lands here: injection molded parts, thermoformed trays and covers, machined plastic components, plastic hardware, knobs and handles, and molded housings.

Defense buyers use it for enclosures and housings for electronics, insulators and standoffs, bushings and wear pads, shims, protective caps and covers, knobs and grips, packaging inserts and dunnage, and plastic components inside aircraft, vehicle and shipboard assemblies. DLA Land and Maritime, DLA Aviation and DLA Troop Support buy the bulk of it by stock number, and the primes buy molded details for production.

What federal buyers typically ask for

Material is the clause that matters. The drawing will call the resin by an ASTM, military or AMS material specification, sometimes by a specific grade, and the buyer wants a material cert and a certificate of conformance with every lot. Aircraft interior parts may add flammability testing, space parts add outgassing limits, and electronics parts may require ESD-safe compounds. First article inspection is routine for a new source, and for a molded part it includes the tooling.

Tooling ownership is the second clause. Many buys include government-furnished molds or require the mold to be delivered, marked and stored as government property, which changes how you price the job. ITAR applies when the part is drawn to a weapon system, and any part with an electronic insert brings the counterfeit part clause. The DFARS specialty metals clause only appears when metal inserts are involved.

Small business set-asides are common, and many buys are small, automated DIBBS awards. Commercial item procedures are used for catalog parts. Molded details for a production line usually reach small molders as subcontracts from the primes.
