The Syria programme’s principal contribution to this reference is the 2019 shipping advisory, which sets out the voyage-level indicators — unexplained deviations, loitering, and calls at anchorages known to be used for transfers — that recur throughout the maritime material.
Humanitarian carve-outs
Syria is also the clearest working example of the tension between comprehensive restriction and humanitarian access. The programmes carry extensive general licences and exemptions for humanitarian activity, and understanding their exact scope matters, because overstating the reach of an exemption is a recurring feature of penalty notices.
That is a general point about general licences: they authorise what they say and nothing adjacent.
