TSI Plastics, Inc.

TSI Plastics, Inc., a Minnesota-based manufacturer of precision-molded plastic components for aerospace and military applications, operates as a prime contractor (35% of awards) and subcontractor (65% of awards) to major defense primes, with a heavily skewed subcontract footprint across Boeing, Lockheed Martin, Northrop Grumman, and Bell Textron. The company is a for-profit Subchapter S corporation headquartered in Anoka, Minnesota, competing predominantly full-and-open on prime work while sustaining an active subcontract engagement across defense platforms and ordnance systems.

TSI Plastics' prime capability portfolio centers on small-volume precision-molded plastic components for DLA logistics supply chains. Representative prime work includes a $20.9 thousand firm-fixed-price delivery order from DLA Aviation (awarded May 2026) for shipping nose plugs under Total Small Business set-aside, scheduled for completion September 3, 2026; a $7 thousand purchase order from DLA Land and Maritime (awarded May 2025) for access covers with no set-aside, completing September 15, 2025; and a $5 thousand delivery order from DLA Aviation (awarded June 2024) for air mixer nozzles. TSI Plastics holds two single-award Indefinite Delivery Contracts with DLA Aviation: a $250 thousand Total Small Business IDC awarded November 9, 2021, expiring November 8, 2026, for shipping plugs and related products, and a $250 thousand Total Small Business IDC awarded October 23, 2024, expiring October 21, 2029, for air mixer nozzle assemblies. These two contracts anchor the prime vehicle footprint; task orders placed against them account for the bulk of recent DLA Aviation awards.

Customer concentration is acute and defense-centric. DLA Aviation dominates with 53 prime awards carrying $1.2 million in combined potential value (85% of prime awards by count, 100% by potential value in the top-customers ranking). The Department of the Navy Naval Air Systems Command accounts for 43 sub awards; the Department of the Army, 15 sub awards; and the Air Force Materiel Command Aeronautical Systems Center, 10 sub awards. This five-customer set covers 85% of award count. The distinction between prime and sub concentration is marked: DLA Aviation is the sole meaningful prime customer, while subcontract awards split across Navy, Army, and Air Force primes.

TSI Plastics' subcontract footprint is substantial and growing. The company subcontracts to Boeing on Space Launch System (SLS) Stages Production and Evolution Contract (SPEC) interiors work (multiple awards in July–August 2026), F-15EX production, MQ-25 unmanned aerial vehicle interiors, and common aerospace commodities across multiple aircraft programs. It supplies Northrop Grumman on Precision Guidance Kit (PGK) production with plastic components including housings, radomes, and cutter ring assemblies (dozens of awards dating from 2024 forward covering ordnance, fuze systems, and electronics manufacturing). Lockheed Martin receives TSI sub work on C-130J Five Year Ordering Contracts (FYOC) for aircraft interior components including sidewall fairings, plenum assemblies, and trim shells; on F-16 Fighting Falcon programs; and on classified avionics support (awards spanning 2022 to 2025). Bell Textron and Alliant Techsystems round out the major sub relationships, with Bell receiving work on AH-1Z helicopter bushings and polyimide-service components, and Alliant receiving 120mm advanced multi-purpose cartridge and ordnance components.

Activity has accelerated sharply. The vendor received 4 awards in 2022, 17 in 2023, 49 in 2024, 33 in 2025, and 9 through August 2026. This trajectory reflects DLA Aviation's increased task order placement against the two established IDCs. The combined potential value ($1.4 million) sits low relative to the combined dollars obligated ($11.7 million), signaling that invoicing and task-order execution exceed initial ceiling estimates — a typical pattern for small-dollar, recurring logistics orders. No recompete cliff is present in the source; the DLA Aviation IDC awarded October 2024 runs through October 2029, providing a five-year runway for continued small-value prime task orders.

The vendor's category footprint reflects its dual role: prime awards cluster in aircraft parts and auxiliary equipment manufacturing (NAICS), while sub awards span aircraft manufacturing, small arms ordnance, and ammunition. Top PSC codes include aircraft hydraulic and de-icing system components, commercial hardware, and ammunition containers. This breadth across ordnance, aircraft interiors, and logistics support components — delivered through major aerospace and defense primes — positions TSI Plastics as a specialized supplier of molded plastic parts across multiple defense platforms rather than as a vehicle or systems integrator.
