Additional handling applies to the following:
Any article that is encased in an outside shipping container made of metal or wood
Any cylindrical item, such as a barrel, drum, pail, or tire, that is not fully encased in a corrugated cardboard shipping container
Any package with the longest side exceeding 100 cm or its second-longest side exceeding 30 inches (76 cm)
Any import, export or domestic package with an actual weight greater than 25 kg.
Each import, export or domestic package in a shipment where the average weight per package is greater than 25 kg and the weight for each package is not specified on the source document or the UPS automated shipping system used.
UPS also reserves the right to assess the Additional Handling Charge for any package that, in UPS's sole discretion, requires special handling.
If you shipped a keg or cask, then this additional handling charge would have already been factored into the Sellar Shipping Courier Rates.
