US Duty Payment

Everything You Ever Wondered About Duties, Customs, and DDU

At Mark 3 International, we like to keep shipping as smooth as silk. That includes explaining exactly what’s going on when we mention DDU and what it means for you. Read on for more clarity and less confusion…

Q. Why am I getting a duty request from Mark 3 (and is it time to panic)?

Firstly, no panic needed. If you’ve ordered goods from outside of the US, they’re subject to duty and tariffs when they arrive.

It can be tricky to calculate the duty and tariffs required by customs for items, so sellers ask us to do it for them—swiftly and accurately—when your goods are on their way. This means you won’t have paid the duty or tariffs when you checked out and the shipper has not paid them in advance either. To get your goods you need to pay as they arrive in the US.

This is known as DDU.

Here’s everything you need to know about DDU (Delivered Duty Unpaid) shipments…

What is DDU?

DDU stands for Delivered Duty Unpaid.

No matter where in the world you are, it’s one of the ways we get your shipment to you.

In simple terms, this means that when you purchased your items from the seller, duties and taxes weren’t paid and instead, would be charged when your goods enter the US.

As part of the service we provide to our customers, we contact you, the recipient, to collect the duties and taxes and ensure your goodies can get to you as soon as possible.

Here’s How Your Order Gets to You and How DDU Works (Step-by-Step) 📦

  1. You order. Easy!

  2. Your item is packed & sent. The shipper gets it ready for you.

  3. Heads-up from us. We’ll email to say it’s on the way and that a duty payment link is coming soon.*

  4. We do the maths. When your shipment reaches us, we calculate the US duty & taxes due.

  5. Quick pay, quick play. We email your total with a secure payment link.

  6. Hold tight (briefly). Your parcel stays in the UK until duty is paid—paying promptly avoids delays.

  7. We clear customs. We settle the duty and handle all the border paperwork.

  8. On the move! Your parcel ships to you and is delivered a few days later. 🎉

  • Duty/tax amounts are set by the U.S. Government and depend on the item and its value.

Security tip: We’ll never ask for card details by phone. Only pay via our secure email link. If something looks off, contact our support team before paying.

What You’ll Get from Us:

  • A clear, upfront notification that duties are due (if any)

  • A simple, secure link or payment process

  • No delays. No surprises. No mystery paperwork (mysteries are for Netflix)
