Round up on weights. GK® rounds up to either the next pound (lb) or ounce (oz). For example, if your package weighs 3 lbs 5 oz, it would be charged at the 4 lb-rate. If you have a First-Class Package Service-Retail™ that weighs 7.3 oz, it must be charged at the 8 oz-rate. This applies to all mail classes—domestic and international.
Verify the mail class. For example, First-Class Package Service-Commercial™ can only be used for packages under 15.999 oz when creating a label through a PC Postage vendor, anything over the weight limit must be shipped with Priority Mail® service. And Regional Rate Boxes A and B have 15 and 20 lbs limits respectively.
