Shopify Will Decide Your Duties Setting for You on August 24 — Unless You Opt Out of Managed Markets First

By Milan Dhameliya · · 9 min read

If your store uses Shopify Managed Markets, every market that still ships delivered-duty-unpaid switches to delivered-duty-paid automatically on August 24, 2026 — no setup required, no error if you do nothing. The only decision is whether you want that default, and Managed Markets is a narrower, separate product from the plain duties toggle in Settings > Markets, which means this changelog item may not even apply to you.

If your store has Shopify Managed Markets turned on, nothing changes for you to do on August 24, 2026 — every market you sell into that still ships delivered-duty-unpaid (DDU) will switch automatically to delivered-duty-paid (DDP), and your customers start paying duties at checkout instead of at the door. The only decision is whether you want that. If you'd rather keep DDU, you have to turn Managed Markets off before that date; there is no partial opt-out inside it.

What almost every summary of this changelog item skips is the first question that actually matters: does Managed Markets apply to your store at all. It's a specific, opt-in product with real eligibility limits, not a rename of the general duties settings every Shopify store has access to — and conflating the two is how a merchant who already did the right thing ends up re-checking a setting that was never theirs to change.

What's actually changing, and when

Shopify announced the change on its developer changelog on August 11, 2026: starting August 24, Managed Markets stops supporting DDU in every country and region where it already supports DDP. Any market that currently ships DDU under Managed Markets inherits DDP instead. Shopify's stated reasoning is straightforward — a customer who pays duties at checkout knows their true landed cost before they buy, instead of finding out at the door with a courier standing there.

For most merchants on Managed Markets, this requires literally nothing. The conversion happens on Shopify's side. The only action item is for the merchant who has a specific reason to keep offering DDU — more on who that actually is below — and for that merchant, the deadline is real: turn Managed Markets off before August 24, or the market converts with it.

Managed Markets is not the duties toggle you might already use

This is the part the announcement doesn't spell out, and it matters more than the deadline itself. Shopify has two separate systems that both touch duties, and they are easy to conflate because they live near each other in the admin:

The August 24 change only touches the second one. If you followed the de minimis advice above and simply switched on duty collection in Settings > Markets, this changelog item does not apply to your store — you're already collecting duties at checkout, under your own merchant-of-record status, and nothing about that toggle is affected by what Managed Markets does. You can stop reading here and skip straight to the "what to check regardless" section below.

Who's even eligible for Managed Markets to begin with

According to Shopify's own requirements documentation, Managed Markets is currently only available to businesses based in the United States, Canada, or the United Kingdom, each with its own fulfillment-location rules — a US business needs a non-PO-box US address and continental US fulfillment, a Canadian business needs all fulfillment locations in the same province, and a UK business needs every location within either Great Britain or Northern Ireland, not split across both. Every eligible store must also use Shopify Payments as its gateway.

That means if your business is registered in Australia, New Zealand, or Ireland, Managed Markets isn't available to you at all right now, regardless of how much you sell internationally — this entire decision is moot for you, and the duties setting you actually want to check is the plain per-market toggle. It's also worth knowing Managed Markets can't run alongside the Global-e app or Shopify Collabs, doesn't cover B2B orders, and won't process a free order with a zero value — none of which is a reason to avoid it, but all of which explains why some merchants who tried to turn it on hit a wall before ever reaching the DDU/DDP question at all.

The actual decision, for merchants it does apply to

If your store is US, Canada, or UK-based, uses Shopify Payments, and already has Managed Markets running, you have three real paths before August 24.

Do nothing, and let it convert

This is the right call for most merchants, and the reasoning is the same one we laid out for the plain DDP toggle: DDU feels cheaper because you're not the one paying the duty, but a customer who gets billed at the door either refuses the parcel — which puts you on the hook for the return leg on top of the outbound shipping you already paid — or pays it grudgingly and sometimes charges back, because an unexpected fee from a courier they've never heard of is exactly the kind of transaction that makes someone call their bank. A guaranteed number at checkout beats a surprise one at delivery for both sides of the transaction.

Turn Managed Markets off, and keep DDU

There's a narrow case where this makes sense: markets where your average order value is low enough that a visible duty line at checkout meaningfully increases cart abandonment, and where your fulfillment and returns economics can absorb the occasional refused parcel better than they can absorb lost conversions from sticker shock at the point of sale. If that's a real, measured tradeoff for your store — not a guess — Shopify's deactivation flow is documented under the Managed Markets settings in Settings > Markets; follow their walkthrough rather than guessing at the clicks, since deactivating also hands merchant-of-record responsibility back to you for every order it was covering.

Go further, with duties-inclusive pricing

Shopify shipped a third option on July 10, 2026, one month before this DDU change, and most coverage of the August 24 deadline doesn't mention it: Managed Pricing folds duties, import taxes, transaction fees, and currency conversion directly into the displayed product price for a market, rather than adding them as a checkout line item. The duty and import tax portion is guaranteed — if the actual amount charged by customs differs, Shopify Managed Markets covers the gap, not you. For a merchant who's already accepting DDP, this is the next step: instead of a customer seeing a base price plus a duties line that can look alarming on its own, they see one clean number that already includes it. It's opt-in per market, on top of the DDP conversion this changelog item forces, not a replacement for it.

What to check regardless of which path you're on

Whether you're on Managed Markets, the plain duties toggle, or neither, the number a customer sees at checkout is only as accurate as two fields on every product: the Harmonized System (HS) code and the country or region of origin. Shopify's Managed Markets requirements documentation lists accurate country-of-origin data as a condition of eligibility, not a nice-to-have, and the underlying reason is the same one that applies to the plain toggle — without both fields, duty gets estimated from your product title and category instead of calculated, and that guess is wrong in both directions on a live store. If you haven't audited this since the de minimis exemption ended, this deadline is a reasonable prompt to do it now rather than after a customer disputes a charge.

It's also worth remembering this sits alongside the market-driven shipping rollout reaching every merchant on October 1 — both are Shopify restructuring how a Market's checkout behavior gets configured and by whom, and if your store or an app you rely on writes to shipping or duty settings programmatically, this is a reasonable point in the year to confirm nothing is quietly relying on the old defaults.

The short version

Check whether you're even on Managed Markets before you do anything else — most stores selling internationally on Shopify are not, and for them this deadline is a non-event. If you are, on the current facts, letting it convert is the right default for most merchants, turning it off is a narrow and specific call for a market with real low-AOV abandonment risk, and Managed Pricing is worth a look as the next step once you've accepted DDP rather than an alternative to it.

If you want a second pair of eyes on which of these three paths actually fits your markets, or help auditing HS codes and country-of-origin data before the deadline rather than after a chargeback, get in touch, or see what I do for stores selling internationally on Shopify.
