Data Sources & Update Frequency
Where TradeLasso's screening data comes from and how often it is updated.
Where does the data come from?
TradeLasso sources all screening data from the U.S. Consolidated Screening List (CSL), available via the official trade.gov CSL API. The CSL is a U.S. government resource that aggregates restricted party lists maintained by the Department of the Treasury (OFAC), the Department of Commerce (BIS), and the Department of State (DTC and ISN).
TradeLasso does not create or modify the underlying list data. We query the authoritative government source and present it through our screening interface.
How often is the data updated?
TradeLasso synchronizes with trade.gov daily. Each day, the latest published version of the CSL is fetched and reflected in search results.
There is typically a short lag between when a U.S. government agency publishes a list update (e.g., a new SDN designation) and when that update propagates to trade.gov and subsequently to TradeLasso. For the highest-stakes, time-sensitive transactions, we recommend verifying directly against the official agency source as well:
Which lists are included?
See Which Lists Are Searched? for the full breakdown of all 13 CSL lists.
Are non-U.S. lists included?
No. TradeLasso currently screens against U.S. government lists only. The following lists are not currently included:
- EU sanctions (European External Action Service consolidated list)
- UN Security Council consolidated list
- UK OFSI sanctions list
- Canada's Consolidated Canadian Autonomous Sanctions List
If your transactions require screening against non-U.S. lists, you will need to supplement TradeLasso with additional screening tools or processes.
Can I rely on TradeLasso data for legal compliance?
TradeLasso provides a technology tool to assist with compliance screening. The underlying data is sourced from official U.S. government publications, but TradeLasso does not guarantee the completeness or timeliness of that data. See our Legal Disclaimer for the full statement.
