@mothered If the label was provided by the company, the contract is between the courier and the company. As long as you show that you have done everything right on your end by proving you shipped everything out its on the couriers and companies whatever happens after. The "sender" would not even be able to file for the insurance claim.

Yes, I understand that and I agree with what you've said, with the exception of the comment below.

As long as you show that you have done everything right on your end by proving you shipped everything out its on the couriers and companies whatever happens after

Given you've boxed the company and signs of tampering has been noticed at the collection point, "you haven't done anything right on your end, nor proved to ship everything out", hence the liability Is not on the company & carrier, but rather your Incapacity to Include the goods as Instructed. 

What you've stated Is relative to goods missing/damaged In transit, and not prior to the package been scanned and accepted In full by the carrier at the collection point. If they raise a damage report, I can assure you that It will release them from being held responsible.

To be honest, it dose not even matter what its in the package. It can be bricks or potatoes even since empty box might not be accepted. I have had few empty boxes just stopped whilst in transit to prevent intercepting. As long as you take pictures prior to shipping out with the correct goods inside you will win almost any claim.
