Shopify Ends DDU on August 24. Opt Out or Auto-Convert

Shopify Managed Markets stops supporting delivered duty unpaid (DDU) on Monday, August 24, 2026, in every country and region where it supports delivered duty paid (DDP). Shopify published the change on its changelog on August 11, nine days before this post, so treat what follows as a deadline reminder rather than breaking news. Four days remain. Markets that use or inherit DDU will move to DDP automatically unless the merchant acts first, and the action available is larger than the headline implies.

The changelog frames the choice as “no action is required” versus “turn off Shopify Managed Markets before August 24, 2026.” Read the second option carefully. Shopify’s own deactivation help page makes clear that turning off Managed Markets for a market does not just restore DDU. It ends Managed Markets’ role as merchant of record for that market, removes the shipping rates that are exclusive to Managed Markets, stops duty and import-tax calculation, and locks the existing Managed Markets orders for that market against editing. There is no documented setting that keeps DDU while remaining on Managed Markets after the cutover.

This guide lays out what the changelog actually says, the timeline as Shopify dated it, why “opt out” is a deactivation decision rather than a shipping-terms toggle, how DDP and DAP are defined on Shopify’s own help pages, a convert-versus-deactivate comparison built only from primary sources, the refund rule that bites after fulfilment, the questions Shopify has not answered, and a four-day plan. It also points to the other Shopify deadline landing the same week, because the two overlap on the calendar and on the people who have to deal with them.

The primary source is a single Shopify changelog post titled “Managed Markets is ending Delivered Duty Unpaid (DDU) support,” published on August 11, 2026. It is short, and its core claims are worth holding to the letter because most of the secondary coverage will paraphrase them loosely.

Three further statements in the same post define the mechanics. First, scope: markets that use or inherit DDU will automatically move to DDP wherever Managed Markets supports it. Second, the customer-facing effect, in Shopify’s words: “Customers in those markets will now pay duties and taxes at checkout, not to the carrier or customs on delivery.” Third, the merchant instruction: if you want customers to keep paying duties on delivery, turn off Shopify Managed Markets before August 24, 2026; otherwise no action is required.

Shopify’s stated reason is that collecting duties and taxes at checkout helps avoid surprise costs on delivery and makes international shopping more predictable. That is the vendor’s rationale, not an audited outcome. No delivery-refusal rate, conversion figure or cost comparison is published alongside it, and this post does not supply one either.

A note on names, because precision matters here. Managed Markets is the merchant-of-record cross-border product, formerly called Markets Pro, in which Shopify states that Global-e is the merchant of record and handles matters such as remitting tax to local authorities. Shopify Markets is the settings layer for selling internationally without a merchant of record. The August 24 change concerns Managed Markets only. If your store sells cross-border on Shopify Markets without Managed Markets, the changelog post does not describe a change to your setup.

Dated honestly, this is not this week’s news. The changelog post went up on Tuesday, August 11. This post runs on Thursday, August 20. The cutover lands on Monday, August 24. That gives a thirteen-day notice window in total, of which nine have already passed and four remain, and the remaining four include a weekend.

The weekday detail matters operationally. A Monday cutover means a market that auto-converts will show duties at checkout to the first customers of the working week, and a deactivation left until the last moment has to be done on Sunday or earlier. Neither is difficult; both are easy to leave too late when the same team is also working through the August 26 checkout script-tag sunset.

Here is the point this post exists to make. The changelog headline reads like a setting is changing its default. The opt-out instruction it gives, turn off Shopify Managed Markets, is not a setting inside the product. It is leaving the product for that market. Shopify’s deactivation help page is explicit about what that entails, and none of it is a shipping-terms preference.

The decision is therefore not “DDP or DDU.” It is “accept DDP and stay on Managed Markets, or leave Managed Markets for that market and take on everything it was handling.” Framed that way, the headline’s implied symmetry disappears.

Shopify’s general duties and import taxes help page defines DDP, and defines the DAP incoterm that covers the customer-pays-on-delivery arrangement. The definitions are not specific to Managed Markets, but they are the vocabulary the product uses, so they are the right reference for the two models either side of the cutover.

The same help page carries the only carrier-behaviour statement Shopify publishes on this topic, and it is a caveat rather than a statistic: some shipping carriers charge additional fees for collecting duties upon delivery if the duties have not been paid in advance, so using the DAP incoterm might result in additional charges to the customer. It says nothing about how often customers refuse parcels or abandon checkouts under either model. Treat any percentage you see attached to this change as unsourced unless it comes with a dated primary reference.

What makes DDP under Managed Markets different from a merchant simply choosing DDP shipping is the guarantee. Shopify’s Managed Markets overview states that the duty and tax amounts displayed at checkout are guaranteed, and that even when the amount charged by customs is different, Managed Markets covers the difference and you do not pay additional fees. That is a mechanism-level reason a converted market is a lower-variance position for the merchant than either DDU or a self-managed DDP label.

One thing not to conflate: Shopify also documents buying DDP shipping labels through named carriers, where the merchant prepays duties on the label and DAP labels leave the customer paying at delivery. That is a label-purchase mechanism, separate from Managed Markets’ checkout-collection and merchant-of-record model, and it is not what the August 24 change is about. Our cross-border selling guide covers the wider landed-cost decision for stores that are not on Managed Markets at all.

The table below puts the two real options next to each other, using only the changelog post and the Shopify help pages linked in this article. No secondary coverage we reviewed lays out the deactivation consequences alongside the conversion consequences, which is precisely the comparison a merchant needs. Most cells are a documented fact or its direct consequence; where Shopify is silent, the cell says so, and where a cell adds a practical instruction, that instruction is our recommendation rather than something Shopify documents.

Read as a whole, the table explains why we expect most Managed Markets merchants to convert rather than deactivate. The right-hand column is not “DDU as before.” It is a different operating model for that market, with the merchant carrying compliance, rates and duty estimation that the product previously absorbed. Deactivation can still be the correct call, for example where a market was only ever on Managed Markets by inheritance and the volume does not justify the product, but it should be chosen as a product decision, not as a way to preserve a shipping term.

Converting a market to DDP means duties, customs fees and VAT become part of what the customer pays you at checkout, which raises a question most roundups skip: what happens to that money on a return? Shopify’s Managed Markets fulfilment help page answers it in two halves, and the halves are not symmetrical.

The practical consequence for a converting market is a returns policy review, not a pricing change. Under DDU the customer paid duties to the carrier and any refund you issued never included them. Under DDP through Managed Markets the duties flow through your checkout, and after fulfilment they do not flow back. Customer support macros, the returns page and any marketplace listing that repeats your refund terms should say so plainly before the first converted order ships.

An honest deadline post has to include the gaps. Four questions a merchant would reasonably ask are not answered anywhere in the changelog post or the Managed Markets help pages we read. We list them as gaps rather than guessing, because a confident wrong answer here is worse than none.

The in-flight question is the one to chase hardest, because it is the only one with money attached on Monday morning. A store with a meaningful number of DDU orders already shipped into a converting market should treat the cutover like any platform change with undocumented edge cases, and our platform-change readiness playbook is the general version of that discipline: know your exposure, brief support, and watch the first day closely.

There is no single right answer, only a right answer per market. The sequence below is built around the one fact that changes everything: the off switch is the whole product, not the shipping term. Work through it for each market that uses or inherits DDU.

Two adjacent items belong on the same checklist. First, Wednesday, August 26 is Shopify’s sunset of script tags and the Additional Scripts field on Thank You and Order Status pages for non-Plus stores, covered in our checkout extensibility deadline post; a store converting markets to DDP on Monday and losing checkout tracking on Wednesday will struggle to read the Monday change at all unless the pixel migration is done first. Second, if you sell into the EU, the EU’s own parcel-duty changes are a reminder that duty collection at checkout is moving from option to expectation in more than one jurisdiction.

If the per-market review, the rate reconfiguration or the measurement setup is more than your team can absorb in four days, our ecommerce engagements handle exactly this kind of platform-deadline work, and our analytics service can stand up the per-market checkout measurement you will want running before Monday rather than after.
