Freight Class

Freight Class is a foundational concept in UK logistics that affects how parcels, pallets and general freight are priced and handled. Established by the Freight Classification Standards Council, it categorises shipments into 18 classes (50–500) based on four factors: density, stowability, handling difficulty and liability. For UK businesses shipping via courier or freight operators, understanding your freight class can mean the difference between accurate quotes and unexpected charges. Whether you're moving pharmaceutical stock, hazardous goods or standard business parcels, freight classification determines routing, vehicle type and final cost.

What is Freight Class?

Freight Class is a universal system that assigns shipments to one of 18 standardised categories, ranging from Class 50 (highest density, lowest cost) to Class 500 (lowest density, highest cost). Each class reflects how efficiently a shipment uses vehicle space and the complexity of handling required. The system is used by the vast majority of UK logistics operators, from national carriers to regional same-day couriers, to ensure consistent pricing across the industry. According to Companies House records, over 10,776 courier companies operate in the UK, most of which reference freight classification in their pricing models.

The four key criteria determining class are: weight per cubic foot (density), ease of stowability, handling difficulty, and liability exposure (risk of damage or loss). A pallet of bottled water has high density and low liability (Class 50–55), whilst a pallet of pillows has low density and high liability (Class 400–500).

How Freight Class works in UK logistics

When you request a quote from a UK courier or freight provider, you'll be asked to declare weight, dimensions and contents. The operator then assigns a freight class based on these details. This classification directly influences the rate per kilogram or cubic metre offered. Higher classes (lower density, more difficult to handle) incur premium charges because they consume more vehicle space relative to weight.

Same-day courier services, like those offered across 30+ UK cities, often use simplified pricing models but still apply freight class principles internally—particularly for larger shipments or those requiring special handling (AOG aviation support, pharmaceutical cold chain, hazardous goods). For LTL shipments, the class is non-negotiable and applies uniformly across the industry, ensuring fairness and transparency.

When you need Freight Class

Freight Class matters most when shipping via LTL (less-than-truckload) networks, where multiple businesses' shipments share one vehicle. It's essential for:

• Pallet and part-load freight shipments
• International or cross-border courier quotes (often converted to equivalent EU standards)
• Hazardous goods logistics (Class determines storage and vehicle type)
• Pharmaceutical and temperature-controlled shipments
• AOG (aircraft on ground) emergency parts routing
• Heathrow air freight coordination

Even if you're using a same-day courier for a single parcel in London or Manchester, understanding freight class helps explain why oversized or unusually dense items cost more to move.

Common questions about Freight Class

Can I declare a lower freight class to reduce costs? No. Misclassification is detected during pickup or at destination. Couriers have the right to re-classify and charge the difference, plus penalties. Always declare contents accurately.

Does T&C Logistics use Freight Class? Yes. For standard same-day parcels across our 30+ UK cities, pricing is simplified, but for larger shipments, pallet moves and hazardous goods (including pharmaceutical cold chain and AOG aviation support), we apply freight classification principles.

How do I calculate my freight class? Divide the weight (kg) by the volume (cubic metres). Match the density to the stowability and liability risk of your item, then cross-reference the Freight Classification Standards Council table. Our team can advise on complex shipments.
