Shipping charges are based on billable weight, which is the greater of:
Actual Weight: Weight of the product and packaging
Dimensional Weight (DIM): (L x W x H) / DIM Divisor
Current DIM divisors:
Economy & Ground: 166
Expedited: 194
International: 139
All carriers round up to the nearest whole pound (e.g. 1.01 lbs = 2 lbs). It is critical that dimensions and weights are accurate in the Atomix App to avoid carrier shipping adjustments, which are passed through to the client.
