There are 2 kinds of standard, true weight
of the heavy goods, gravity of volume of
light goods. Gravity of volume is decided by
the volume of goods.
For heavy goods, true weight is always
bigger than Gravity of volume. Now couriers
use it to calculate shipping cost. e.g
rolled oil painting without stretched and
framed, or stone.
For light goods, Gravity of volume is much
bigger than true weight. Now couriers use it
to calculate shipping cost. e.g
framed/stretched oil & acrylic painting or
sponge.
So we don't suggest that ship
framed/stretched oil & acrylic paintings by
air, the shipping cost will be very
expensive.
The reasonable and cheapest shipping method
for framed/stretched oil & acrylic painting
is by sea. 18-35 days as usual. |
