    Description, as the server wrote it
    Total the ADR 1.1.3.6 points for a vehicle load and say whether it stays within the small-load exemption (1,000 points, or the quantity limit for one transport category), and what still applies. Covers 92 UN numbers. If any line cannot be read the whole load is refused, never totalled without it.

    Description, as the server wrote it
    Read a UN packaging mark part by part (packaging code, performance level, density or gross mass, test pressure, year, state, maker; IBC, large packaging, salvage and reconditioned marks too). Add a UN number to check whether the container may carry that substance under ADR 2025.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
