What is IMDG segregation?
Segregation asks whether different goods may travel in the same cargo space on a ship.
In HazSeal's sealed sea view: PERMITTED means the matrix does not require extra separation for that pair; REQUIRES_SEGREGATION means keep them apart at the stated level; NEEDS_REVIEW means the engine could not decide from sealed data — do not guess, consult your TMGD/DGSA.
Declaration accuracy remains the shipper's responsibility. Sea mode uses the IMDG 41-22TR dataset (unofficial Turkish publication; English IMDG text prevails where they diverge).
IMDG 7.2
Plain-language orientation with article references. Not a certification. Where HazSeal cannot decide from sealed data, it answers NEEDS_REVIEW.
