Claude: 

After examining the video, which I had not seen before we spoke, I believe the artwork is repairable. Accordingly, there may be a simpler resolution if DHL is willing:

• Ship it back to our studio for repair with no shipping charge and with customs entry as a temporary import for 12 months or less so there are no customs charges.
• Waive the original AKL to SIN shipping charge.

We will then repair the artwork and ship it back to the client. We will use a much more expensive packaging system, effectively making the artwork into a crate so it will not suffer damage if cooked in 30°+ transit storage in Singapore.

We would prefer to do this rather than make a $7,500 insurance claim (plus any DHL charges) because premiums are generally based on claims history, and in this case, the artwork should be repairable.
