When it comes to selling a semi-trailer, determining its worth can be rather challenging. There are many factors that come into play when calculating the value of a trailer, such as the make, year of manufacture, size, capacity and condition.

Fortunately, at Truck Trading, we have over 20 years of experience assessing the market prices for used trucks and semi-trailers. We can help provide you with a reliable estimation. Let’s delve into each factor in order to understand how they can contribute to the overall value of a semi-trailer.


The make of a semi-trailer can be an important factor that impacts its overall value, but not to the same extent as trucks and tractor units. Different manufacturers may offer additional features and capabilities, which will influence its overall worth. Reputable brands such as Schmitz, Dennison, Fruehauf, Montracon, Gray & Adam, SDC, Feldbinder and Spitzer can be worth more than lesser-known brands due to their superior build and reliability.


The purpose of the semi-trailer is also a critical factor in determining its value. For example, refrigerated semi-trailers are in demand as they provide businesses with an efficient way to transport and store goods at a controlled temperature for an extended period of time. This makes them desirable for a wide variety of industries, such as food production, pharmaceuticals and logistics.

Bulk liquid ADR/chemical trailers are also highly sought after as they are designed to transport hazardous and non-hazardous liquids over long distances safely and securely. Manufactured from either stainless steel or aluminium, these specialised trailers are often insulated with steam coils to protect cold-sensitive liquids during transit making them more valuable than the standard semi-trailer.

Year Of Manufacture 

Age is always going to be a big factor in valuing any asset, as is the case with semi-trailers. The older a semi-trailer is, the less value it’s likely to have, as newer models will always be more sought after by potential buyers. Having said that, some older classic models can still fetch a reasonable price depending on the condition, so don’t be hasty in writing off an older trailer just yet.

Size and Capacity

It’s no surprise larger trailers are typically more costly than smaller ones as they can carry larger loads, making them a valuable asset for business owners. The size of the trailer is also a factor that attracts more potential buyers due to its versatility. Many logistics companies and hauliers are interested in purchasing bulk tipping trailers due to their ability to transport large amounts of material from one place to another in fewer trips. This makes them a cost-effective and efficient solution, resulting in buyers willing to pay a higher price tag for these types of trailers.


The mileage of a semi-trailer does not play a major role in dictating its overall worth. Of course, a well-maintained semi-trailer will be more valuable than one with visible wear and tear. But it certainly doesn’t mean it’s worthless; minor defects can be expected due to the nature of its use. So whether you are looking to purchase or sell your semi-trailer, be sure to keep hold of any records of repairs and maintenance to prove its roadworthiness.
