SIU LIMITED Partnership

SIU LIMITED Partnership, an international non-profit organization headquartered in Khon Kaen Province, Thailand, provides interpretation and translation services, logistics support, transportation, medical supply procurement, and equipment provision to the U.S. Navy as a prime contractor operating exclusively in Southeast Asia. The vendor has held a SAM.gov registration since August 2023 and competes on full-and-open purchase orders with no set-aside designations.

SIU LIMITED Partnership serves a single customer agency — the Department of the Navy's Chief of Naval Operations — across 23 awards totaling $440 thousand in combined potential value. The vendor's capability portfolio is heavily weighted toward interpretation and translation services (7 awards by NAICS), supporting Navy training programs including Sea Vision, SMEE, human rights training, and the Worldwide Port Security conference. Representative prime contracts include a $76,589.93 firm fixed-price purchase order awarded February 1, 2023, for three consecutive interpreters and translation services supporting the Military Information Support Team and Civil-Military Support Element team with completion through January 31, 2024; a $220,936.66 purchase order awarded September 15, 2023, for a mobile refrigerator or freezer system to support the Ministry of Health in Laos; a $28,226.56 purchase order awarded September 30, 2023, for medical supplies supporting the Community Military Supported Education project at the northern Thailand border; and a $3,333.33 purchase order awarded January 26, 2026, for interpreter service support for Sea Vision training scheduled for completion by January 30, 2026.

The vendor's secondary capability concentration spans passenger car rental (5 awards), miscellaneous logistics and support services (5 awards), and medical equipment and supplies (2 awards). Transportation services and equipment rental are typically smaller engagements under five thousand dollars, as are fuel provision, vessel rental, and logistic support for specific Navy operations in Thailand and Laos. All work is performed in Southeast Asia, primarily Thailand, with the Navy's overseas presence and security cooperation missions as the operational nexus.

Activity has contracted significantly year over year — 13 awards in 2023, 6 in 2024, 3 in 2025, and 1 in 2026 — reflecting either declining Navy engagement demand or competitive displacement. No subcontract footprint is present in the source; the vendor operates exclusively as a prime. All obligations totaling $440 thousand have been invoiced as of the source date.
