This is a total small business set-aside procurement for an FCR Interface Box built to L3Harris Technologies part number 14021-4011-01, with no associated technical drawings or data because the cited part/catalog number is fully descriptive. The contractor must meet the ordering-data design and manufacture requirements, maintain a Government-acceptable inspection system, follow specified packaging such as MIL-PRF-23199 and MIL-STD-2073 where applicable, and comply with mercury-exclusion requirements. A Certificate of Compliance per DI-MISC-81356 is due at material delivery, with separate certificates for each unique contract/purchase order, NSN, and item nomenclature combination. Delivery is FOB destination, and pricing is valid for 60 days unless otherwise specified. Contract document issuance may occur by mail, fax, or electronic commerce, and Government acceptance of the contractor’s proposal forms a bilateral agreement to those issuance terms.
