DIM Weight is short for dimensional weight. It’s a billing method that uses the total volume of a package (length x width x height) to calculate shipping costs instead of using the package's actual weight. Shipping costs are based on whichever is greater: the physical weight of the package or the dimensional weight.
If the DIM weight is greater than the actual weight, DIM weight is used instead of the package’s actual weight. If the package volume is less than 1 cubic foot and the package weight is less than 1lb, then the DIM weight is ignored.
For US Domestic services packages, we will use a 166 divisor to calculate dimensionally. The 166 divisor is also used for Canada.
DIM Surcharges in the US:
An oversize charge applies to packages that exceed 96" in length or 130" in length and girth. Rating will be based on the greater of the package's actual rounded or dimensional weight, subject to a 90lb minimum billable weight. Any packages over 20 lbs must be pre-approved.
An additional $4 surcharge is added for packages with any dimension over 22". An additional $8 for any dimension over 30". An additional $19.50 is applied to packages that measure more than 48 inches on the longest or more than 30 inches on the second-longest side.
DIM Surcharges in Canada:
When packages are over specific dimensions, carriers charge ShipHero (the shipper) additional fees. The additional DIM surcharges are applied, and the fuel surcharge is applied on top of the DIM surcharge. For example, if the shipping costs $10 and the oversized charge is $30, the Fuel surcharge is rated off the total of $40.
- Extra Care Surcharge*
Applicable to any package where a single dimension exceeds 60 inches (152 cm) in length: $22.00 per package - Overweight Surcharge*
Applicable to any package or article greater than 70 lbs (32 kgs) in actual weight: $30 per package - Oversize Surcharge*
Applicable to any package where the length and girth exceed 130 inches (330cm). Length is defined as the longest side of the package. Girth is the distance around the two smallest sides of a package or object. Girth = 2(W+H): $85 per package
Important :
- If the package qualifies for more than one DIM surcharge, it will be charged at the highest rate.
- ShipHero will charge DIM fees even if using USPS Media Mail method.
