Each country in the lists names the source for its rule; countries not listed had no qualifying national law in these sources. Laws as of November 2026. We map the law on the books, not how well it is enforced.
United States: Signed, not ratified. The US signed the High Seas Treaty on 20 Sep 2023 and has not ratified it, so it is not bound. Treaties are federal, so states don't differ. Law: Signatory, not a party, to the BBNJ Agreement (UNTC XXI-10). Treaty membership is federal.
