Introduction

A returned order that crosses a border doesn't just reverse the outbound shipment. It creates a second, separate customs event, and most return policies were never written to handle it.

The Return Leg Now Has Its Own Customs Problem

Two 2026 rule changes made this unavoidable. The EU is removing its €150 de minimis exemption on July 1, 2026, and the US has suspended Section 321 de minimis treatment for all countries of origin. Low-value parcels that used to slide through customs with minimal scrutiny now go through formal declaration on the way in.

Merchants have spent the year adjusting outbound logistics for this. Fewer have thought about what it means for the package coming back.

If an order was formally declared and assessed duty on the way into the customer's country, the returned item doesn't just quietly reverse that process when it ships back. It triggers its own customs event, on its own timeline, with its own paperwork.

Before 2026, most merchants never noticed this, because most low-value parcels avoided formal declaration going both directions. That grace period is closing on both sides of the Atlantic at once, which means the return leg is a new operational problem for a lot of stores in the same year, not a slow-moving trend.

What Actually Happens When a Returned Order Crosses Back

There are two ways this plays out, and most merchants have never had to manage either one at scale.

Duty Drawback

If duty was paid on the way in and the item is being returned unused, the merchant may be able to file for a refund of that duty. This is called a duty drawback filing. It requires matching the return to the original import record, providing proof the goods left the country again, and submitting it to customs within a defined window.

None of this happens automatically. It's a manual filing process, and it takes weeks, not days.

Formal Re-Import Declaration

When the returned goods land back in the merchant's home country, customs may treat that arrival as its own import, not a simple reversal. That means a commercial invoice, correct HS codes, and a formal declaration before the item clears and the warehouse can process the refund.

Both paths add real time and real paperwork to a return that a merchant may have promised would resolve in days.

The Refund Speed Bar You Can't Hit With a Copy-Pasted Policy

Shoppers expect fast refunds. 68% now expect a full refund within three business days on a domestic return. That bar was already tight before 2026. It is structurally impossible to hit on an international return that has to clear customs twice.

This is the actual root cause behind slow international refunds and the support tickets that come with them. It isn't that international shipping is inherently slower. It's that most merchants write their return policy around domestic mechanics, a label, a transit estimate, a refund date, and then bolt "international returns accepted" onto the bottom of it without pricing in the customs step on the way back.

The result is a policy that quietly promises something the customs process won't let the merchant deliver.

How to Write Your International Return Policy Around This

Should international returns get the same refund SLA as domestic?

No. Publish two separate SLAs. Keep the domestic promise as it is, and publish a distinct, explicit, longer window for international returns that names the customs step as the reason for the difference.

Vague language like "international returns may take longer" generates a ticket every time. A specific number, with the reason attached, generates far fewer.

Who pays the re-import duty on a returned item?

Decide this before a customer asks, not while a support ticket is open. Someone eats the re-import duty on a returned item: the merchant, the customer, or it gets built into how international pricing is structured from the start.

Whatever the answer, put it in writing in the return policy itself. A support agent improvising an answer to this question in real time, differently each time, is how a return policy quietly turns into a trust problem.

When should a returned item just not come back at all?

For low-value international orders, run the math before authorizing the return. If the cost of the customs round trip, duty, brokerage, and handling on both legs exceeds what the item is worth, shipping it back doesn't make sense for anyone.

In those cases, a store credit or a keep-the-item resolution gets the customer to a fast outcome without triggering a second formal customs event over an item worth less than the paperwork to move it.

Does this apply to every international return, or just certain order values?

It scales with order value and origin country, not a single flat rule. A returned $18 phone case and a returned $400 jacket do not carry the same customs math, and a policy that treats them identically will either overpay on the cheap item or under-serve the expensive one.

Segment the policy by value from the start. Set a threshold under which items default to store credit or a keep-the-item resolution, and reserve the full return-and-re-import process for orders where the item's value clearly justifies the paperwork.

What should merchants have ready before this comes up?

A defined process, not an ad hoc one. That means knowing in advance which returns qualify for duty drawback, which ones require a formal re-import declaration, and which low-value returns get sent to store credit instead of a physical reship. Building this decision tree once, before volume forces the question, is far cheaper than solving it ticket by ticket.

Conclusion

None of this is a reason to stop accepting international returns. It's a reason to stop treating them like a domestic return with a longer shipping label.

ShipAid Returns & Exchanges lets merchants set separate return rules and resolution paths for international orders, including store credit and keep-the-item options for low-value items, so the decision is made in the policy instead of improvised in a support ticket.

FAQ

Why do international returns get processed through customs twice?

A returned order crosses the border in the opposite direction from the original shipment, and that arrival is treated as its own customs event. If duty was paid when the item first entered the customer's country, the return does not automatically reverse that charge. It triggers a separate declaration when the goods land back in the merchant's home country.

What is a duty drawback filing?

A duty drawback filing is a request to get back the duty that was paid when an item first entered the country, once that same item is returned unused. It requires matching the return to the original import record and proving the goods left the country again, and it can take weeks to process.

What is a formal re-import declaration?

A formal re-import declaration is the paperwork customs requires when returned goods arrive back in the merchant's home country. It typically includes a commercial invoice and correct HS codes, and the item cannot clear customs or trigger a refund until that declaration is filed.

How fast should merchants promise refunds on international returns?

Slower than the domestic promise, and the difference should be stated explicitly rather than left vague. A specific window that names the customs step as the reason tends to generate far fewer support tickets than language like "international returns may take longer."

Should every international return ship back to the warehouse?

Not if the item is low in value. When the cost of duty, brokerage, and handling on both legs of the customs round trip exceeds what the item is worth, a store credit or keep the item resolution gets the customer to a fast outcome without triggering a second formal customs event.

Who should pay the re-import duty on a returned item?

Whoever the merchant decides in advance, whether that is the merchant, the customer, or a cost built into international pricing from the start. The important part is putting that answer in writing in the return policy itself instead of leaving a support agent to improvise it case by case.
