Sajjad, Zainab S.

Sajjad, Zainab S., doing business as Xenab International, is a women-owned small business (WOSB) sole proprietorship based in Cypress, California, that supplies mechanical and electrical replacement parts to the federal government as a prime contractor. The vendor holds SBA certifications as a women-owned small business, minority-owned business, and self-certified small disadvantaged business, and competes across both full-and-open and set-aside categories, with set-aside awards (Total Small Business and Woman-Owned Small Business) recurring across roughly one-quarter of the recent prime contract footprint.

Xenab International's federal work centers almost exclusively on supplying discrete mechanical and electrical components—windshield wiper assemblies and motors, battery storage units, gaskets, temperature controllers, circuit breakers, navigational lights, swivel casters, fluid filters, seals, and fasteners—to support military equipment maintenance and logistics. Representative work includes a $168 thousand Coast Guard purchase order (July 2026) for replacement vessel reduction gear components (temperature transmitters, bearing units, seals, shaft couplings, locknuts) from David Brown Santasalo, a $139 thousand DLA Land and Maritime Total Small Business set-aside (March 2025) for 38 pendulum window wipers, and a $100 thousand DLA Land and Maritime Total Small Business set-aside (February 2025) for windshield wiper assemblies. Nearly all work is performed at the Cypress facility; shipping typically targets DLA Distribution centers or military depots across CONUS and OCONUS.

Customer concentration is extreme and narrow. The Defense Logistics Agency Land and Maritime dominates the footprint at 1,103 awards (49% of the total 2,259-award count) representing $23.9 million in combined potential value—52% of the total $45.5 million portfolio. The next four customers account for just $13.5 million combined: the US Coast Guard (154 awards, $3.8 million), DLA Aviation (258 awards, $3.3 million), the Department of the Army (22 awards, $3.3 million), and Naval Supply Systems Command (168 awards, $3.1 million). By dollar value, the gap widens further—DLA Land and Maritime alone represents over half the portfolio. This vendor has no presence on government-wide acquisition contracts (GWACs), schedule vehicles, or multi-agency IDIQs; instead, it holds direct indefinite-delivery contracts (IDCs) with DLA Land and Maritime and DLA Aviation.

Xenab International maintains nine single-award Indefinite Delivery Contracts, all with DLA Land and Maritime or DLA Aviation, each carrying a $250 thousand to $350 thousand ceiling. Recent IDCs include a $350 thousand contract (March 2026) for windshield wiper assemblies (NSN 2540017135088), a $350 thousand Total Small Business contract (March 2026) for damper inertia components, a $350 thousand Total Small Business contract (February 2026) for direct current motors, a $350 thousand contract (February 2026) for swivel casters, and a $350 thousand contract (January 2026) for windshield wiper assemblies. The vendor also references a $3 million Blanket Purchase Agreement with the Department of the Army for spare parts supporting foreign military sales, though that vehicle does not appear to drive recent award volume in the source data.

Activity has been volatile. The vendor issued 190 awards in 2024, but fell to 141 in 2025 and only 34 in the first seven months of 2026 (suggesting a potential sharp decline or a lag in SAM reporting). Only three awards in the next twenty-four months carry ultimate completion dates, with combined potential value of $168 thousand, indicating minimal recompete exposure in the near term but also raising questions about pipeline sustainability. The vendor does not subcontract; all 2,259 awards are prime contracts, and no sub-award history appears in the source.

The vendor operates as a sole proprietor without named teaming relationships or significant subs. Its footprint shows no diversification beyond DLA and Coast Guard—the top five customers account for 80% of awards and 82% of dollar value. While Xenab International holds recurring set-aside positions (Total Small Business, Woman-Owned Small Business), it also competes full-and-open on the same component categories. The business model is transactional: high-volume, small-dollar purchase orders and delivery orders for inventory replenishment, with little evidence of strategic or technology-driven differentiation.
