What happens if I don't put the proper shipping weight as a seller? Understate the shipping weight? You will be invoiced


Billable weight is the weight used to calculate the rate. For domestic and international services, the billable weight will be the greater of the dimensional weight compared to the actual weight.

Determine the Actual Weight

Actual weight is the package weight rounded up to the next whole pound.

Use a scale to determine the weight of the package. 

Determine Dimensional Weight

Dimensional weight reflects package density, which is the amount of the space a package occupies in relation to its actual weight. Dimensional weight may apply to all UPS domestic and international package services.

Determine the package dimensions in inches. For each dimension, measure at the longest point, rounding each measurement to the nearest whole number (for example, 1.00 to 1.49 will be considered 1, and 1.50 to 1.99 will be considered 2).

Multiply the package length by the width by the height. The result is the cubic size in inches.

For Domestic Shipments:

Divide the cubic size in inches by 166 to determine dimensional weight in pounds. Increase any fraction to the next whole pound.

Determine Billable Weight

Compare the package's actual weight to its dimensional weight. The greater of the two is the billable weight and should be used to calculate the rate. For multiple-package shipments, total the billable weight of all packages in the shipment.

Additional Information on Determining Weight and Size

Letter rates apply for domestic and international documents, correspondence and electronic media shipments that do not exceed eight ounces sent in a UPS Express® Envelope. Domestic letters greater than eight ounces will be billed by weight (rounded up to the next whole pound). Export letters greater than eight ounces and up to two pounds will be billed at UPS Express® Pak rates. Export letters greater than two pounds and import letters greater than eight ounces will be billed by weight (rounded up to the next whole pound).

UPS Express Pak rates apply for export shipments that weigh two pounds or less, do not exceed $100.00 in customs value and UPS Express Pak is selected at the time of shipping.

Irregularly Shaped Packages: If the package has a bulge or is irregularly shaped, measure the length, width and height of the package at its extreme points, which may include the bulge or irregular aspects of the package. Treat the irregularly shaped package as if it were in a regular rectangular box. Measure the length, width and height of the package from its extreme points.

Items Shipped in Bags:

Shape - When multiple items are shipped in a flexible container (e.g., burlap or plastic bag), the package measurements will be determined when the exterior is at rest. As this shape will differ from placement to placement, cubic size or package measurements will be made at the sole discretion of UPS.

Tails - A tail on an item shipped in a bag should be measured for the amount of space it takes up in a reasonably compressed fashion. Any tail that is created by placing an item in a bag must be compressed and taped to the body of the item.

Packages that exceed UPS weight and size limits are not accepted for transportation. If found in the UPS system, they are subject to an Over Maximum Limits charge.

A Large Package Surcharge may apply to domestic and international shipments. A package is considered a "Large Package" when its length plus girth [(2 x width) + (2 x height)] combined exceeds 130 inches.

Large Packages are subject to a minimum billable weight of 90 pounds. An Additional Handling charge will not be assessed when a Large Package Surcharge is applied.

Shippers are responsible for providing accurate and complete shipment information on the shipping document or in the automated processing system used, including service selected, number, weight and dimensions of packages. UPS reserves the right to audit any package and/or invoice to verify service selection, package dimensions or weight and applicability of any charges. As part of that audit, UPS may weigh and measure any package tendered to UPS using any method UPS deems appropriate including, but not limited to, multidimensional measuring devices. If any aspect of the shipment information provided by the shipper is incomplete or incorrect as determined by UPS in its sole and unlimited discretion, UPS may in its sole and unlimited discretion adjust charges at any time.

Notes: Size limits indicated by a box manufacturer may not reflect exterior dimensions of a package, including where a package may have bulges or otherwise may not be uniform across each plane, and should not be used as a substitute for actual length, width and height measurements in determining dimensional weight.

Improper packaging may result in the alteration of a package's dimensions during transit which can affect the package's dimensional weight and result in a shipping charge correction.

How to Convert Tenths of a Pound to Ounces

  1. Identify the part of the number that you're going to convert. Your starting point should be a number like 5.75 pounds. The .75 denotes the tenths of a pound, so that's the part that you would be converting. Note that the number before the decimal, the 5, is your total number of whole pounds.
  2. Type the number of tenths of a pound into your calculator. Make sure that you include the decimal. It will probably automatically add a zero, in which case your number will look something like 0.75 pounds.
  3. Multiply that number by 16. There are 16 ounces in every pound, so to convert from tenths of a pound to ounces, you just multiply by 16. The answer will be your total number of ounces.
    • 0.75 times 16 ounces equals 12 ounces.
    • Note that to reverse this process, you simply have to divide by 16 rather than multiplying. So, if your original quantity is 5 pounds, 12 ounces, you could just divide 12 by 16 to get 0.75 pounds. Then add the 5 back in, and 5 + 0.75 equals a total of 5.75 pounds.
  4. Write your original number in pounds and ounces. The number of whole pounds from your original number is all the numbers to the left of the decimal. The number of ounces is the answer that you got when you multiplied the tenths of a pound by 16.
    • For the example of 5.75 pounds, the answer would be written 5 pounds, 12 ounces.
