Delivery is required within 62 days after order placement, with a stated deadline of September 17, 2026, under FOB Origin terms to the DLA Distribution facility in New Cumberland, Pennsylvania. All items must comply with MIL-STD-2073-1E packaging standards and be sealed in a medium-duty, waterproof, greaseproof, opaque bag per MIL-DTL-117, Type II, Class C, Style 1, due to the sensitivity of the item to ultraviolet degradation. Marking must adhere to MIL-STD-129 with no special marking required. The item is classified as a critical application item and must be free of asbestos as defined in FED-STD-313. Mercury or mercury-containing compounds are prohibited unless part of functional components such as batteries, fluorescent lights, sensors, controls, weapon systems, or NAVSEA-specified reagents; when present in portable lamps or instruments, a secondary containment and shockproof design per NAVSEA 5100-003D is mandatory. The contract imposes stringent regulatory and compliance obligations under multiple FAR and DFARS clauses, including requirements for combating human trafficking, employment eligibility verification, sustainable products, hazardous material identification, cybersecurity safeguarding, and prohibition of internal confidentiality agreements. Contractors must submit Safety Data Sheets for any hazardous materials per 29 CFR 1910.1200 and comply with labeling and notification protocols for radioactive substances exceeding thresholds outlined in MIL-STD-129. Transportation via sea requires prior notification to the Contracting Officer and MARAD, with preference for U.S.-flag vessels and mandatory documentation of vessel usage. Payment must be processed electronically via WAWF, and the contractor must maintain active SAM registration. All subcontractors exceeding the simplified acquisition threshold must flow down applicable clauses, including those for hazardous materials and transportation. The solicitation is issued under a simplified acquisition procedure, with no evaluation factors, weights, or award basis specified, suggesting a potential LPTA approach. The contract is unclassified and uses a fixed-price line item with zero variance in quantity, requiring full compliance with packaging, marking, safety, and delivery standards without allowance for deviation
