When the D&T are part of the price, the D&T are deducted from the amount Global-e pays you and we hand them over to the Authorities on your behalf.
IMPORTANT- this amount does not usually come from your pocket as in general a coefficient is added to that relevant country which increases the price of the product so the D&T are not from your pocket.
Example: UK merchant selling to a Spanish customer
D&T = 15 % that the customer is required to pay
Therefore the coefficient that needs to be added is 15%
Item is 100 GBP converted to Euro is ~ 115 Euro
D&T on this order would be 115 Euro * 15% = 17.25 Euro
Additional coefficient of 15 %= 115 GBP converted to Euro ~ 134 Euro
Global-e will deduct 17.25 Euro from the 134 Euro meaning the amount you receive is 134 – 17.25 = 116.75
