Everything You Wanted to Know About FREIGHT CLASS CALCULATOR and Were Too Embarrassed to Ask

Weight and cubic volume play a key factor in U.S. domestic carrier freight charges.

Our free freight class calculator can help you determine the freight class of your shipment.

Determining your Freight Class Based On cargo Density

Our freight class calculator is to be used as a guideline for a range of products that are usually classified as density products.When shipments require special handling, stow ability or are of higher than usual value, they will have a different freight class usually higher, in order to confirm your freight class, you can contact


.Not all US trucking companies use freight class.Canadian trucking firmsdo not use freight class, they use dimensional weight and not all US trucking firms use freight class either.The advantage of determining your freight class is that in certain circumstances a density/class calculator could calculate a class of 70 when your product is a class 50 as per the NMFTA. You would under these circumstances get a reduction in rate by overriding the calculator and forcing it to use class 50. However, you would need to input the NMFTA Class number that corresponds to your products class onto the bill of lading in order to prove this fact.

National Motor Freight Association

The NMFTA freight classification system takes into account three other factors into their classification system, which are stow-ability, handling, and liability – which are used when special care is required.

Stow ability

  • When your freight cannot be loaded together with general shipments.
  • When Hazardous materialsmust be shipped in a particular manner.
  • Large weight, lengths or protrusionsmake your freight impossible to ship alongside other cargo.
  • When you skid cannot be stacked.
  • Under any of these circumstances above, a stow-ability classification would apply.


  • Freight is usually loaded with forklifts and has no handling difficulties, but some cargo due to their weight, odd shape, fragility or hazardous properties – would require special attention and care.
  • Under these instances, a handling classification would apply, which would be based on the degree of difficulty to load and transport.


  • Other freight is much more susceptible to pilferage or theft.
  • Some shipments are delicate, perishable, or can damage adjacent shipments– including cargo prone to spontaneous combustion or explosion.
  • Liability-classified freight falls into several freight classes, dependent upon density.

Other Freight Class Essentials

Your freight class can make a huge difference to your freight cost calculation. As an example, a shipment that weighs one hundred pounds thatcost $ 150 in class 50, woulddoublein class 125, and be ten times that expensive in class 500.At times increasing the weight of a shipment just slightly can lead to big freight savings by adding just enough weight to slip into the next PCF (pounds per cubic foot) range. That’s because heavier weight classes cost less per pound and increasing the weight just enough to just cross into the next PCF cost range is usually always to your benefit.Reducing sizes can also lead to big freight savings. Verifycommon pallet and box sizes, and use the smallest suitable box and pallet size, taking into account that the shipment should just fit inside the pallet footprint in order to protect the cargo during loading and trans-loading.However, always remember that using the wrong freight class can as well cause issues: extra freight costs, freight claim difficulties, and carrier re-billings (extra costs, shipment delays, invoice inconsistencies).Author:Pierre is an entrepreneur and co-founder of

The Most Effective Way To Dispute A Carrier Re-weigh Charge

Carrier Re-weigh are a common frustration in the shipping industry. This usually stems from the fact that a large percentage of shippers are ill-equipped and do not have large enough certified scales to weight the skids being shipped, or just don’t have the time to weigh each individual skid prior to shipping  relying on internal documentation that was produced several years ago, usually forgetting to include the weight of each pallet (typically 40 lbs) to the shipment in question.

Carrier re-weigh

Since a change in the total weight of a shipment can have a dramatic impact on your rate, as well as legally create an issue for the carrier who is bound to run trailers below 45,000 lbs for a typical 53-foot dry van in North America. They weigh certain shipments in order to remain within the legal weight limits of the department of transportation. If the shipment in question does not conform to the stated weight on the bill of lading, then a re-weigh inspection form is created and a re-weigh is performed incurring additional charges to the shipper. 

What’s the most effective way to dispute a carrier re-weight?

If you just received your carriers invoice and were stunned at the rate increase that you never approved, chances are that its a carrier re-weight. However, you can dispute the re-weight charge by following this usual procedure but it must be done correctly for you to get the best chance of reducing or eliminated the increased re-weigh fees.

All Skyfer Logistic carriers posses certified scales during a carrier re-weight inspection and provide re weight and inspection certificates detailing the reasons for such increases. If you are convinced that the carrier re-weight & inspection is wrong you can dispute the carrier re-weight charge by following a few steps.

What documentation should be submitted to the carrier in order to correctly dispute the carrier re-weight charge?

Most common carriers require two distinct documents in order to accept a claim that disputes a carrier re-weight. These two documents must be official docs from the shipper or manufacturer and not a handwritten annotation.

A. Product Spec Sheet – This is a sanctioned document from the manufacturer or shipper that contain basic information about the shipment in question, including its Weight, Dimensions, and Description

B. Shipment Packing Slip – This paper comes from the shipper and is usually included with the skids during transit. It would itemize each product in the shipment along with the number of pieces and weights. The weight on the packing document and the Bill of Lading is the total weight of the shipment which includes the skid or skids.

In order to have a much better chance of success in the dispute of a carrier re-weigh, we suggest that it be made within a few days of being invoiced. Claims against a carrier re-weight can take anywhere between two weeks and a couple of months, so patience is a virtue in this case.

Most freight brokers worth their salt will assist you in filling a carrier re-weigh claim or even perform it on your behalf, Skyfer Logistic certainly does. Once the process is complete, they will usually provide you with a claim number that you can track and discuss any further issues with the carrier in question. This claim number is your proof that the process has started and is in the carriers claim system. If your dispute is approved you will be re-invoiced the correct amount and your original re-weight invoice will be voided in their system.

4 Reasons to Review Your FAK Agreements ASAP

FAK (Freight All Kinds) agreements enable multiple items to be shipped and billed under a single freight class. For shippers dealing in various freight classes, these contracts can generate immense efficiencies. They allow for a streamlined process by reducing costs (admin and operational) for both parties involved (the shipper and the carrier). BUT, as time passes, the benefits of many FAK agreements evaporate. They then turn into unnecessary drains and inefficiencies, which inflate the freight bills of unaware shippers.

The tables have turned. Driver shortages and increased HOS regulations have made shipping a seller’s market. More and more, shippers are the ones competing for carrier services.
