NAICS 491110 – Postal Service encompasses the operation and support of mail and package delivery systems, including sorting, transportation, routing, and distribution of postal matter under the authority of the United States Postal Service. While primarily associated with the USPS itself, this NAICS code also covers contracted services that enable postal infrastructure, such as logistics support, fleet maintenance, mail processing automation, secure document handling, and last-mile delivery solutions. In the federal contracting landscape, this code represents a specialized niche where operational continuity, regulatory compliance, and nationwide reach are critical. Contractors in this space often provide mission-critical support to ensure the reliable movement of sensitive and non-sensitive mail across federal agencies, including classified and diplomatic correspondence. Top contractors in this sector include D2 GOVERNMENT SOLUTIONS, INC., a small business specializing in logistics and postal support services for federal clients. The competitive landscape is dominated by firms with expertise in government logistics, supply chain management, and secure transportation, with a strong presence of small businesses and service-oriented primes leveraging specialized certifications. Primary awarding agencies include the U.S. Postal Service, the Department of State, and the Department of Defense. These agencies rely on postal services for secure mail distribution, diplomatic pouch transport, veteran correspondence, and military personnel mail systems. Demand is driven by the need for reliable, auditable, and secure mail handling across domestic and international operations. The market is characterized by steady, recurring demand with low volatility, as postal operations are essential to federal continuity. Opportunities exist for contractors with experience in federal logistics, automated mail systems, and compliance with postal regulations such as USPS Handbook M-41. Contracting is highly relationship-driven, with incumbency and proven performance in secure mail environments providing significant advantages.

Contract Delivery Service (CDS) HCR 968A1 KEAAU, HI - H005, HI, AMENDEDThe contract solicitation for Contract Delivery Service (CDS) HCR 968A1 KEAAU, HI – H005, HI, as amended, is issued by the U.S. Postal Service under Solicitation Number 801-927-26 and Contract Number 968A1, with a North American Industry Classification System (NAICS) code of 491110. The service is scheduled to begin on August 8, 2026, and will extend through July 31, 2032, covering a Highway Contract Route that requires transportation services between Keaau, Hawaii, and H005, Hawaii, with strict adherence to a defined schedule including load/unload times at 0800 and 1545, departure from Keaau at 1015, and arrival at H005 at 1530. All operations must comply with the Postal Operations Manual, with Section 66 taking precedence over contract terms in case of conflict. The solicitation has been amended to require a vehicle size increase to 240 cubes, and all mail must be transported in an enclosed, waterproof compartment with secure locking devices maintained at all times except during permitted access. Suppliers must submit proposals via PS Form 7405 and PS Form 7468A, detailing all cost elements—including vehicle, operational, labor, and wage expenses—with pricing expressed as an annual rate and inclusive of all anticipated costs, and are prohibited from requesting adjustments for mileage variance. Proposals must be submitted electronically by 10:00 AM Mountain Time on July 16, 2026, to amy.warnecke@usps.gov or via fax to 651-456-6819, and must include full compliance with provisions covering insurance, safety, equipment standards, employee screening, and organizational conflict of interest prohibitions. Suppliers are required to maintain workers’ compensation and vehicle insurance at their own expense, ensure all vehicle systems meet federal and state safety standards, and comply with the Fair Labor Standards Act and Service Contract Act. Evaluation is based on a best-value approach where technical factors—including past performance, supplier capability, and operations plan—carry more weight than price, though no single factor carries a pre-defined point value. Supplier Eligibility is a mandatory pass/fail gate; failure to meet any requirement disqualifies the offeror. Sub

The solicitation, numbered 810-1086-26, requires offerors to submit a complete Proposal Submission Package via email to amy.warnecke@usps.gov or by fax to 651-456-6819, with all submissions due by 10:00 AM Mountain Time on July 9, 2026. The scope of work entails transporting all mail tendered along the 41.0-mile route with certainty, celerity, and security, including loading, unloading, mail exchange, minor administrative tracking services, and potential additional trips as directed under the Changes clause. The service requires compliance with specific vehicle standards (VH120), frequency zone code 0730, and strict safety protocols for load distribution, equipment securing, and driver conduct during hazardous conditions. Pricing is established using the fixed-price structure with economic price adjustment, based on the Rate of Compensation stated in Box 2 of PS Form 7405, supplemented by the cost worksheet PS Form 7468A, with all proposed costs required to be fully enumerated and expressed to no more than four decimal places; contract price remains fixed regardless of actual mileage variations.

The evaluation is non-numerical and prioritizes technical factors over price, with proposals assessed through pass/fail gates for supplier eligibility and then evaluated across four weighted factors: past performance, supplier capability, operations plan, and price. Technical excellence is critical, and award will be made based on best value, not necessarily lowest price or highest technical score. The contract enforces compliance with federal labor standards including the Service Contract Act and Fair Labor Standards Act, mandates equal opportunity employment practices for protected veterans and individuals with disabilities, and requires annual reporting on subcontracting to small, minority, and woman-owned businesses.
