What are the USPS 2020 price changes?¶
Please see USPS Price Changes.
What is USPS cubic pricing?¶
USPS® cubic pricing provides high-volume shippers discounted rates on small, heavy parcels. Rates are based on parcel size and shipping distance, not on parcel weight.
Requirements
Cubic pricing is available for high-volume Priority Mail (PM
) shippers,
usually those who ship more than 50,000 parcels a year. Cubic pricing is
available only for the SOFTPACK
and PKG
parcel types.
Qualifying parcels can be rectangular, non-rectangular, or soft packs, but they cannot be rolls or tubes:
- A rectangular or non-rectangular parcel must:
- Weigh no more than 20 pounds.
- Have a longest dimension of no more than 18 inches.
- Measure no more than 0.5 cubic feet. USPS uses the following formula to
measure cubic feet:
Length x Height x Width / 1728 = Cubic Feet
- A soft pack must meet the following requirements. The
measurements must be taken prior to placing the item in the envelope:
- The sum of the longest and next-longest dimensions must not exceed 36 inches.
- The longest dimension must not exceed 18 inches.
- The smallest dimension must not exceed 2 inches.
When is cubic pricing applied?
When a qualifying shipper prints a Priority Mail label, Pitney Bowes checks if the parcel qualifies for cubic pricing. If it does, Pitney Bowes calculates both the cubic rate and weight-based rate and then applies the rate that is more cost-effective.
Pitney Bowes always applies the better rate
Whenever a parcel qualifies for cubic pricing, Pitney Bowes checks the weight-based rate as well and applies the rate that is more cost-effective.
More information
For more information on cubic pricing, see Commercial Plus Cubic on USPS.com.
How are rates calculated for USPS soft packs?¶
Soft packs (SOFTPACK
) are flexible packages that adhere and conform to the
contents being packaged and that, as a result, take up minimum cubic space. A
soft pack must meet the following requirements. The measurements must be taken
prior to placing the item in the envelope:
- The sum of the longest and next-longest dimensions must not exceed 36 inches.
- The longest dimension must not exceed 18 inches.
- The smallest dimension must not exceed 2 inches.
When you specify that a parcel is a soft pack, Pitney Bowes calculates rates based on following and then applies the more cost-effective rate:
- 2-dimensional cubic pricing, which is based on the soft pack’s dimensions.
- Weight-based pricing.
The label will have markings corresponding to the rate applied.
For supported services for soft packs, see the SOFTPACK
entry in
this table.
What is USPS dimensional weight pricing?¶
Dimensional (DIM) weight pricing applies to packages that are large and relatively light for their sizes. DIM weight is calculated based on volume and a volumetric divisor.
For USPS shipments, you can calculate whether DIM weight applies to a given package using the USPS DIM weight calculator. See https://www.usps.com/dimensionalweight/.
Note: A package might alternatively be subject to oversize pricing.
What is USPS Oversize Pricing?¶
Oversize pricing applies if the parcel’s combined length plus girth falls between 108 and 130 inches.
Which charges apply when my request includes a Shipper Rate Plan?¶
If your request to Rate a Parcel or Create a Shipment
includes the X-PB-Shipper-Rate-Plan
request header, which specifies a
shipper rate plan, then in the response the rates
array returns the
following:
- If the shipper does not have an NSA:
- The
alternateBaseCharge
andalternateTotalCharge
fields are based on the shipper rate plan. These contain the shipper’s charges. - The
baseCharge
andTotalCarrierCharge
fields are based on the developer’s rate plan.
- The
- If the shipper has an NSA:
- The
baseCharge
andTotalCarrierCharge
fields are based on the NSA. These contain the shipper’s charges. - Do not use the
alternateBaseCharge
andalternateTotalCharge
fields.

What is USPS Commercial Pricing?¶
Commercial Pricing provides shippers with lower prices than the retail prices offered at USPS locations. Commercial Pricing has no volume requirements and is usually available through online shipping providers. The current prices are found in the Commercial Prices section of the USPS Price List.
Note: USPS formed Commercial Pricing in 2019 by merging Commercial Base Pricing (CBP) and Commercial Plus Pricing (CPP) into one discount level. While both Commercial Base and Commercial Plus are found in the USPS Price List, they offer the same prices. They differ only in that Commercial Plus alone is available for Cubic Pricing.
What is a USPS Negotiated Service Agreement (NSA)?¶
For a shipper with a very high volume, a Negotiated Service Agreement (NSA) provides discounts based on a contract between the shipper and USPS.
For more information, see this USPS document: https://pe.usps.com/cpim/ftp/manuals/dmm300/709.pdf
When rating a package, can I send multiple package details in a single request?¶
No. Currently, the PB Shipping APIs do not support the processing of
multiple parcels in a single rates request. You must
include only one parcel
object, as shown here:
curl -X POST .../v1/rates?includeDeliveryCommitment=false \
-H "Authorization: Bearer <oauth_token>" \
-H "Content-Type: application/json" \
