About the company
Chang-Castillo & Associates LLC, a minority-owned, Hispanic American-owned limited liability partnership based in Richmond, California, provides translation, interpretation, revision, and multilingual linguistic support services to federal agencies as a prime contractor on full-and-open competitive contracts without set-aside designations. The vendor is a self-certified small disadvantaged business that competes successfully across federal agencies on language services contracts ranging from small task orders to larger delivery orders, with 100% of its recent federal award footprint delivered as prime work rather than subcontract activity.
Chang-Castillo's customer base concentrates heavily on the Department of State, which accounts for 96% of recent award volume. The Department of State Bureau of Administration dominates by far, holding 84 awards with $1 million in combined potential value across multiple blanket purchase agreements and task orders. The Department of Agriculture has emerged as the second-largest customer, though with a different value profile: while USDA accounts for only 20 awards (11 from the Food Safety and Inspection Service, 7 from the Office of the Secretary, and 2 from the Foreign Agricultural Service), those awards carry $2.8 million in combined potential value — nearly three times the State Department's dollar concentration. This divergence reflects State's heavy reliance on small, frequent language-services task orders ($55 to $3,659 typical range) versus USDA's larger delivery orders for Codex Office translation work ($89 thousand to $227 thousand per order). A single USDA Office of Procurement and Property Management award carries $4 million in potential value, indicating a significant ongoing engagement.
Chang-Castillo holds five active blanket purchase agreements, all with the Department of State Bureau of Administration, spanning multiple annual ceilings. The primary vehicles are BPA 190PRL25A0397 (10 task orders, $12 thousand combined potential value, through September 2026), BPA 190PRL24A0397 (23 task orders, $28 thousand combined potential value, through September 2024), and BPA 190PRL23A0397 (26 task orders, $192 thousand combined potential value, through September 2023). A larger indefinite-delivery contract with USDA, AG3A94C140006, carries 12 task orders worth $845 thousand in combined potential value and centers on translation and interpreting services for the U.S. Codex Office's work on international food safety standards in English, Spanish, and French.
Representative work includes a $226.9 thousand USDA delivery order (January–December 2022) for translation and interpreting services to the Office of the Secretary; a $149 thousand delivery order (through August 2025) for qualified Codex Office document translations in the three official FAO working languages; and an $89.6 thousand USDA delivery order (completed March 2024) for similar Codex Office translation support. State Department work splits across dozens of smaller BPA calls, including a $4.8 thousand call (October 2025) and a $2.9 thousand call (October 2025), both for general language services in Washington, DC.
Award activity declined sharply after 2023: 28 awards in 2022, 25 in 2023, 9 in 2024, and only 3 recorded in 2025 through mid-year. Combined potential value across all 111 awards sits at $8 million, with only $2.3 million (29%) obligated to date. The category concentration is nearly absolute — 110 of 111 awards fall under NAICS 541800 (Translation and Interpretation Services), with performance in Washington, DC and San Francisco serving State Department diplomatic and administrative needs and USDA food-safety technical translation requirements. The vendor does not subcontract; all awards are prime delivery.
