The U.S. Coast Guard is seeking quotations for 1,600 oil filter elements (NSN 2940-01-493-8177) used in main diesel engines, requiring the Rolls-Royce Solutions GmbH brand part or an approved equal that meets specified physical, functional, and performance characteristics. The award will be a firm fixed-price contract on an all-or-none basis using lowest price technically acceptable, and this solicitation is a total small business set-aside under NAICS 333998 (500-employee size standard). Quotations must confirm the ability to meet strict packaging, packing, marking, and bar-coding requirements per MIL-STD-2073-1E and MIL-STD-129R, as standard commercial packaging is unacceptable and will result in rejection. Offerors must include a completed FAR 52.212-3, state their status regarding inverted domestic corporations, and be registered in SAM with a valid DUNS number. No specific budget, performance location, or non-bid timelines are provided beyond the submission deadline, which is excluded per instructions.
