Can the DOT “Glass be Half Full”? Under IATA, and IMDG rules the Limited Quantity Limits are based on the quantity within an inner packaging. So gasoline has a 500 mL limit under PI Y341. So you could put 500 mL in a one liter bottle as IATA/ICAO is only concerned with net qty per inner.
49 CFR//DOT on the other hand limits the “capacity” of the inner packaging to 500 mL so you could NOT put 500 mL in a 1000 mL inner packaging. Do you agree?
