Tansomboon Chamroen

Tansomboon Chamroen, a sole proprietorship based in Germantown, Maryland, provides foreign language translation, interpretation, and language support services to the Department of State as a prime contractor on full-and-open BPA calls, with no set-aside designations across its federal footprint.

Chamroen operates exclusively as a prime contractor — all 68 awards in the source are prime BPA calls against Department of State Bureau of Administration vehicles. The vendor specializes in Thai and Lao language services but delivers broader translation capabilities including video captioning, participant consent forms, country profiles, transportation coordination for international events, and logistical support for diplomatic engagements. Performance takes place in Washington, D.C. across all current work. Recent representative contracts include a $19,776 BPA call awarded October 1, 2025, for general language services with completion July 14, 2026; a $12,400 firm fixed-price call awarded October 1, 2024, for language services completing December 14, 2024; and a $4,518 call awarded October 1, 2021, for travel services and logistical support for the Group of Twenty summit.

Customer concentration is extreme: the Department of State Bureau of Administration accounts for 63 of 68 awards (100% of combined potential value at $836 thousand), with four additional awards from the broader Department of State ($27 thousand) and a single $3 thousand award from the Department of Justice. Chamroen has maintained a continuous relationship with the State Department since 2014.

The vendor holds positions on five successive Department of State Bureau of Administration Blanket Purchase Agreements, each with $100,000 to $250,000 ceilings. The active vehicle is Blanket Purchase Agreement 190PRL25A0345 (13 task orders, $61 thousand), followed by 190PRL24A0345 (15 task orders, $42 thousand) and 190PRL23A0345 (12 task orders, $29 thousand). Task order ceilings under these vehicles range from $150 to $19,776 and are issued on firm fixed-price terms.

Activity has contracted year over year — 16 awards in 2023 declining to four in 2025 — with combined potential value of $867 thousand against $217 thousand in obligated dollars (25% realization rate). The decline reflects the natural rhythm of BPA task-order volume on a specialized language-services vehicle rather than systematic recompete loss; all active BPA vehicles run through fiscal year 2026, anchoring near-term work continuity.
