Do federal staff inspect American ships coming into Hawaii or American Samoa? Interesting question. I don't know. In general, US states and territories only have very limited jurisdiction over interstate commerce, which is primarily a Federal responsibility. For example the state of California inspects vehicle traffic crossing their border for the presence of pests. But California's power over interstate commerce is quite limited. The US Supreme Court ruled that they could only regulate interstate commerce in order to serve "a legitimate local purpose that could not adequately be served by available nondiscriminatory alternatives" that would otherwise comply with the commerce clause of the U.S. Constitution. https://en.wikipedia.org/wiki/California_Border_Protection_Stations https://en.wikipedia.org/wiki/California_Border_Protection_S...
