USPS Priority Mail shipping rules for large packages

[primeusa]

I understand that they are new dimensions measurements for USPS Priority Mail when shipping large box packages over 1728 cubic inches.

Does USPS really enforce these rules now with Priority Mail?

If this is true, then I will lose a big profit margin when shipping these large packages that are over 1728 cubic inches.

I would rather not sell items that are over 1728 cubic inches and stick with the smaller packages.

What do you think?

in my opinion for big packages use the UPS, but when its comes to dimensional weight USPS is too much expensive, either use UPS or try to sell small items, dimensional weight is also one of reason why its killing the sellers or stopping sellers from selling over 1728 cubic items.new tarrifs + USPS cost is killing sales day by day.

Yes, they do.

Since about 2008, USPS had been charging a dimensional weight for Priority Mail packages over 1 cubic foot (1728 cubic inches) that were going to Zones 5 - 9.  Starting on June 23, there are 3 changes:

1. Dimensional weight now applies to all zones, not just 5 - 9.

2. Dimensional weight now applies to Parcel Select Ground as well as to Priority Mail.

3.  The divisor, formerly 194, is now 166.
