VAT charged by DHL on goods payable?

I purchased goods in China and this order was cleared by DHL. I received an invoice on which VAT is charged on the value of the order (DUTY AT). There are also other costs that are subject to standard 21% VAT.

When I enter this expense invoice, the difference between excluding VAT and including VAT is only a few pounds (out of a total of 119 pounds).
The largest part of the invoice consists of duty VAT, which is also VAT. Can I also deduct this part from the original amount excl. VAT?
