How Claimlane picks a shipping agreement
When a customer has selected the products to return, Claimlane looks at the combined weight of those products and only offers shipping agreements whose weight limits fit the shipment. Agreements can also be limited to specific countries.
Minimum and maximum weight: An agreement is only offered when the shipment's weight falls within its limits.
No maximum weight means no upper limit: If an agreement has no maximum weight, it can be offered for any shipment, including heavy items or pallet goods that the carrier cannot actually handle.
Product weight comes from your product data: Weight limits only work when your products have a weight in Claimlane.
Example: You use GLS for parcels and DSV for pallets. DSV has a minimum weight set, but GLS has no maximum weight. A pallet shipment then still matches GLS, and the customer can book a GLS parcel label for it. Setting a maximum weight on the GLS agreement fixes this.
What are the default shipping dimensions?
By default, shipping agreements use:
40 x 40 x 40 cm
Many carriers charge on volumetric weight, which is calculated from the dimensions. At 40 x 40 x 40 cm, the volumetric weight can be around 12.8 kg, even for a much lighter package. Smaller defaults, for example 15 x 15 x 15 cm, bring the billed weight much closer to the real weight.
How to set weight limits and dimensions
Both are configured per shipping agreement:
Go to Manage company
Open Shipping Agreements in the left hand menu
Open the relevant agreement and find the Weight, price and dimensions section
Set the minimum and maximum weight the carrier accepts for this service
Update the Length, Width, Height values to your desired defaults
Save each field with the green checkmark, then generate a test label to confirm the right agreement and dimensions are used

Tips / troubleshooting
Set a maximum weight on every parcel agreement: This is the most common reason a parcel carrier is offered for heavy or oversized shipments.
Avoid gaps between agreements: If one agreement goes up to 10 kg, let the next one start at 10 kg. The minimum weight includes the exact value, so a shipment of exactly 10 kg still matches.
Check product weights: If products are missing a weight, weight limits cannot be applied correctly. Make sure weight is included in your product data.
Check country availability: Some carriers only offer return labels from certain countries. Make sure each agreement is only enabled for the countries the carrier supports.
Check which agreement is used: If you have multiple shipping agreements, make sure you updated the one actually used for label creation.
Dimensions vs weight: Even with smaller dimensions, actual weight can still push the price up, so verify both.
If you don't know dimensions: Some merchants set conservative "small parcel" defaults to avoid overpaying, but you should confirm this aligns with what you ship.
FAQ
Why was my customer offered a parcel label for a pallet shipment? The parcel agreement most likely has no maximum weight, so it matches every shipment. Add a maximum weight to that agreement.
What happens if no agreement matches the shipment? No shipping option can be offered for that shipment, so make sure your agreements cover the full weight range you want to handle with labels.
Will this affect all shipments? It affects labels created using the shipping agreement or agreements you updated.
Can I set different dimensions per shipping option? Yes, dimensions are configured per shipping agreement, so you can have different defaults per agreement if needed.
