A.
If the EQ Code is E1, E2, E4 or E5 and it satisfies stipulations of DGR 2.6.10.1 (a) through (d), the substance is categorized as De Minimis Quantities, and when carried as cargo, it will not be subject to these Regulations. Since this exemption only applies when carried as cargo, the prohibition on carriage as baggage and/or post spelled out in 2.6.2.1 applies. As long as it is transported as cargo, it will be treated as non-dangerous goods and segregation will not be necessary. Attention must be given that if the EQ Code is E3, even if the quantity may be very small, it will not be handled as De Minimis Quantities since E3 substances are PG I and the degree of hazard is higher and therefore not eligible for De Minimis Quantities.
