Go beyond showing import fees. Tax & Duty King now adds tax and duty as a payable line item, so customers see the charge and pay it with their order. Pair it with DDP (Delivered Duty Paid) shipping so goods arrive without extra covered import charges.
With DDP shipping, no extra covered import charges on delivery. DDP setup explained
Illustrative example, not a live tax calculation.
You asked for more than an estimate. Tax & Duty King now adds the tax and duty charge as a payable line item, so your customers can pay it upfront with their order.
A clearly labelled tax & duty line item makes the import cost visible before the customer pays.
Your customer pays the tax & duty charge alongside their products and shipping, in one upfront total.
Pair the collected charge with Delivered Duty Paid shipping so those import charges are not billed again on arrival.
More confidence at checkout. Fewer surprise bills at the door. Give international shoppers the clarity they have been asking for.
Understand DDP setup →DDP fulfilment must be arranged with your carrier. Merchants remain responsible for customs clearance and payment of applicable import charges.
When shoppers discover unexpected import fees after delivery, they refuse packages, file chargebacks, and leave negative reviews. The problem starts at checkout — they simply don't know what they'll owe until it's too late.
Customers refuse packages when surprise customs bills arrive — you lose the product and the sale.
International shoppers abandon carts when they can't estimate the true total cost of their order.
Incorrect duty calculations can expose your business to customs penalties and delayed shipments.

International trade law is complex and changes frequently. Tax & Duty King has the rules built in so you don't have to worry about them.
For UK sellers shipping to the EU — orders under €150 from IOSS-registered sellers have VAT collected at checkout, so no import VAT is charged at the EU border. We detect this automatically.
EU-origin goods shipped to the UK qualify for zero customs duty under the TCA. We verify origin rules and apply zero-duty logic where eligible.
Tax & Duty King applies the current US import threshold automatically for US customers, reflecting the latest regulatory position.
