performance standards of this packing group.
b) The Q value: the highest
permitted net quantity per package according to the formula below, whereas Q
must not exceed 1.
|
Formula: Q = |
n1 + n2 + n3 |
|
|
M1 + M2 + M3 |
n1: the
quantity you actually want to ship
M1: the
quantity allowed by the blue pages
The end result MUST NOT exceed 1
The calculated "Q" value must be rounded-up to
the first decimal place and entered on the Shipper's Declaration.
