Damaged Shipments
All Pro Truck Parts is not responsible for damage that occurs in transit - responsibility for damaged shipments lies with the carrier. However, we are glad to assist by filing a claim with the carrier on your behalf.

If your package arrives damaged, please do the following:

1. Refuse delivery if the package is visibly damaged at the time of arrival, and note the damage with the driver.
2. If the damage is discovered after delivery, photograph the outer packaging BEFORE opening the box, then photograph the contents showing the damage.
3. Keep all original packaging, including boxes, packing materials, and labels. Carriers may require an inspection before approving a claim.
4. Notify us within 48 hours of delivery by submitting a damaged shipment report at help.allprotruckparts.com/damaged-shipment.

Once a claim has been filed, resolution is determined by the carrier. Refunds and replacements for damaged shipments will only be issued after the carrier approves the claim. Failure to report damage within 48 hours, discarding the original packaging, or opening a visibly damaged package without photographing it first may result in the carrier denying the claim, in which case we are unable to refund or replace the item.
