What the government is buying

The Department of the Navy is soliciting bids for filter elements for fluid applications. This falls under Federal Supply Classification (FSC) 4330, which covers various types of filters and filtration equipment used with fuels, lubricants, coolants, and other fluids. Filter elements are replaceable components that remove contaminants from fluids in engines, hydraulic systems, and industrial equipment—critical for maintaining operational readiness of naval vessels and aircraft.

NAICS code 333998 refers to "All Other Miscellaneous General Purpose Machinery Manufacturing," a category that includes industrial filter manufacturing and other specialized machinery not classified elsewhere. This suggests the requirement involves commercially produced or specialty-manufactured filtration components rather than custom-engineered systems.

Key facts

Who can bid

This is a full and open competition with no small-business set-aside, meaning large and small businesses may submit offers. Manufacturers registered under NAICS 333998 or businesses with relevant filtration product lines should evaluate whether they can meet the technical requirements and delivery terms.

To bid, you must be registered in SAM.gov with an active registration valid through the contract award period. Your registration must include this NAICS code in your profile. Past performance with defense supply contracts or similar fluid filtration products may strengthen your offer, though the specific evaluation criteria are not in the metadata.

How to put together a competitive bid

For full and open manufacturing solicitations, focus on these elements:

Technical compliance: Review the specification sheets carefully—FSC 4330 items often have precise dimensional, material, and performance requirements (flow rates, micron ratings, pressure differentials). Proposing alternates without approved equivalents typically disqualifies your bid.

Pricing strategy: With no set-aside, expect competition from established defense contractors and large manufacturers. Analyze your production capacity and supply chain to offer your most competitive price while maintaining margin. Consider whether long-term pricing arrangements or economic price adjustment clauses apply.

Past performance: NAVSUP WSS values demonstrated reliability. Document on-time delivery rates, quality acceptance history, and any existing NAVSUP contracts. If you're new to defense work, emphasize relevant commercial experience and any ISO or quality certifications.

Small-business consideration: Though not set aside, small businesses still benefit from subcontracting plan requirements that large bidders face on certain contracts. If you qualify, consider whether teaming as a subcontractor to a larger prime offers better entry than direct competition.

Packaging and marking: Defense supply contracts typically require strict MIL-STD or commercial packaging standards and DOD logistics markings. Noncompliant shipments risk rejection and payment delays.

Next steps

Download the full solicitation from SAM.gov using solicitation number N0010427RBA90. The solicitation will contain the complete specification, quantity, delivery schedule, evaluation factors, and any approved sources or brand-name justifications.

Note the deadline: All offers must be submitted by December 4, 2026, at 11:59 PM Eastern Time. Allow adequate time for SAM.gov technical registration issues and proposal preparation, particularly for obtaining any required technical data or testing certifications referenced in the specification.
