Why is UPS weight calculation showing 99lbs instead of 50lbs?

Topic summary

UPS shipping weight in abandoned checkouts was much higher than product weight (e.g., a 50 lb item showed 99 lbs; a 10 lb item showed 53 lbs), leading to higher shipping prices and checkout abandonment.

  • Initial hypothesis: It might reflect a UPS Ground maximum (99 lbs). This was tentative and required testing.
  • Further observation: Lighter products also showed inflated weights, reinforcing a miscalculation concern.
  • Root cause found: A default package (box) weight was set to 49 lbs in shipping settings, which was being added to product weight at checkout, inflating totals.

Outcome/Action:

  • Correct the default package weight in the shipping/packaging settings to reflect the actual box weight. Verify weights across products after adjustment.

Notes:

  • Screenshots were provided to illustrate the discrepancies.
  • Discussion reached resolution once the misconfigured package weight was identified.

Hi @navyspeed

My understanding is it means the maximum lbs you can have to use UPS Ground. To check this theory, please try another product, if the 99 lbs is still the same, then my theory is true
