When using Endicia to send your shipment via First Class Mail International, you might have noticed that sometimes on the label Endicia will automatically increase the weight up with a couple of ounces.
This is due tot the fact that there are specific weight ranges where the cost is the same. Please find the ranges below:
- 9-12
- 13-16
- 17-20
- 21-24
- 25-28
- 29-32
- 33-36
- 37-40
- 41-44
- 45-48
- 49-52
- 53-56
- 57-60
- 61-64
Therefore, if you had an order that was 10 ounces, it would show up on the label as 12oz. Similarly, a 62 oz. shipment would have 64oz. on its label.
