USPS PMI - Flat Rate
(flat rate shipping in specially formated cardboard boxes)

In 2008 USPS introduced new format of shipments called Flat-Rate.

Flat rate envelope or package has fixed format, there is one size of envelope and three formats of cardboard boxes that you can ship for fixed price. All packaging is provided by USPS free of charge. Anything that fits the packaging and is upto weight limit ships for one flat price. These flat rates are provided only within USPS Priority Mail International (later just USPS PMI), they cannot be used with Express shipping


USPS flat-rate ENVELOPE - large envelope

- envelope dimensions: 12.5″ x 9.5″ ( 31.75 x 24 cm)
- maximum weight: 4 lbs (1.8 kg)
- envelope can fit tshirt, small book or couple of magazines. Envelope cannot be deformed much otherwise envelope would lose its status of flat rate and would be charged standard PMI rates which is more than twice as much.

flat rate postage: $48.95
Note: Forwardo provides 50% discount on fees for consolidated shipping if the shipment fits the envelope.

USPS flat-rate SMALL - small box

- box dimensions: 8-5/8" x 5-3/8" x 1-5/8" ( 21.85 x 13.72 x 4 cm)
- maximum weight: 4 lbs (1.8 kg)
- into small box you can fit eg. two tshirts, small electronics without retail box (mostly used stuff purchased on eBay), compact cameras, cell phones etc. Ideal for used iPhones.

flat rate postage: $48.95

USPS flat-rate box MEDIUM - medium size box

- box dimensions: 11” x 8-1/2” x 5-1/2” (28 x 21.6 x 14 cm)
- maximum allowed weight: 20 lbs (9 kg)
Box is ideal for bunch of standard sized magazines, books, autoparts or any small but heavy items. If your shipment weighs over 7 pounds and can fit this box you save on postage.

Flat rate postage: $102.55

USPS flat-rate box - large box

- box dimensions: 12” x 12” x 5-1/2” ( 30.5 x 30.5 x 14 cm)
- maximum allowed weight: 20 lbs (9 kg)
This box can accept about 1 1/2 load of medium box and if your content weighs over 9 pounds and can fit the box you will save on postage.

Flat rate postage: $132.05

And now we would like to break popular myth that these boxes can fit an elephant. They are not. These boxes are relatively small and if the content requires additional cushing because its fragile then there is not gonna be much of space left if any. Thats why usage is limited to really heavy and small stuff like books, magayine collections, autoparts etc.

In case weight of the box exceeds 20 pounds (9 kg), USPS would charge standard postage rate for given weight with USPS PMI, so instead of $102.55 (resp. $132.05 for large box) for flat-rate box they would charge $116.40 for 21 pounds of weight and more. We take care of that to make sure box weight doesn't exceeds weight limitations.

… and what do packaging magicians at Forwardo say?

During packaging of your shipments we take in account size and weight of the shipment shipped with USPS Priority Mail and if it fits one of the flat rate boxes we ship that way. Flat rate is not in standard offer but you can explicitly ask for flat rate packaging in the note for shipment. We go even that far if it pays off to split shipment into two flat rate boxes we will do it for you without asking.

Our goal is to let you pay as low postage as possible, we work for you and with you to slash the price and optimize the shipment as possible.
