How do UPS real time rates calculate an estimated shipping charge if the items do not have values for weight?

AI generated answer (using internal Slack threads):

Based on the conversations, UPS real-time rates primarily calculate shipping charges based on the weight of the package. If the items do not have values for weight, it could lead to inaccurate or zero shipping costs. It's important to note that the UPS real-time rate calculator may not take into account box dimensions, but primarily focuses on package weight. In some cases, if the weight is not provided or accurate, it could lead to issues with the shipping cost calculation. Some companies even resort to weighing each package individually to ensure accurate shipping costs. However, it's also worth noting that other factors can affect the calculation of shipping costs, such as the shipping address and third-party billing information. If these are not correctly set, it could also lead to zero or incorrect shipping costs. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
