Shipping a heavy parcel isn’t as simple as dropping it off at your local post office. Whether you’re a business sending machinery across the country or an individual delivering a large household item, choosing the right courier for heavy parcels is critical. Standard parcel services often have strict weight limits and hidden surcharges that can complicate or even block your shipment. That’s why it’s essential to understand how different couriers for heavy parcels handle heavy loads, what they charge, and what restrictions apply.
In this 2025 guide, we’ll break down everything you need to know about using a courier for heavy parcels—from pricing models and dimensional weight formulas to packaging requirements and the best courier options for both domestic and international delivery.
What Qualifies as a Heavy Parcel?
A heavy parcel is typically any package that exceeds 30 kg (66 lbs), but limits vary by courier and country. Couriers classify these based on both actual weight and volumetric weight (calculated from the parcel’s size). If either exceeds the limit, your package is considered “heavy” or “oversized.”
Common thresholds:
| Courier | Max Weight (Standard Service) | Heavy Parcel Handling |
|---|---|---|
| Royal Mail (UK) | 30 kg | Above 20 kg incurs surcharges |
| UPS | 70 kg | Charges based on dimensional weight + handling |
| FedEx | 68–150 kg | FedEx Freight applies beyond 68 kg |
| DHL | 70 kg | Special services required over 70 kg |
| Zig Couriers (UK) | 50 kg+ | Custom delivery for heavy items |
Pricing Models for Heavy Parcel Couriers
Pricing for heavy parcels depends on a few key factors:
1. Actual Weight vs. Volumetric Weight
- Actual Weight: The physical weight measured in kg or lbs.
- Volumetric (Dimensional) Weight:
Formula:(Length × Width × Height) ÷ 5000(in cm)
Whichever is higher is used for pricing.
2. Distance and Zones
Longer distances (especially international) and rural deliveries cost more. Rates are often broken into zones or postcode bands.
3. Surcharges
Heavy parcels may incur additional fees:
- Handling surcharges (for items 25–70 kg+)
- Overlength fees (for items longer than 120 cm)
- Fuel surcharges
- Remote area delivery charges
4. Courier Type
- Standard courier: Limited handling, lower costs
- Freight services: Pallet shipping, white-glove options, but costlier
- Specialized couriers (like Zig Couriers): Tailored pricing based on item size, shape, and urgency

What Are the Shipping Restrictions?
Every courier has rules that impact whether your heavy item will be accepted. These may relate to:
1. Maximum Dimensions
Each courier has limits on length and girth. For example, UPS restricts items longer than 274 cm without extra charges.
2. Packaging
Heavy parcels often require:
- Reinforced double-wall boxes
- Palletization (for items over 70 kg)
- Weight-distribution padding (to avoid crushing)
Improper packaging may void insurance or result in delivery refusal.
3. Contents
Some heavy items are restricted or prohibited, including:
- Batteries (lithium or otherwise)
- Perishable food above weight thresholds
- Hazardous materials (e.g., chemicals, fuels)
- Glass items over 30 kg (may not be insured)
4. Insurance Limitations
Most basic services only cover minimal insurance. For expensive or fragile heavy items, purchase additional cover or use couriers offering full liability like DHL or Zig Couriers.
