- Short answer
- Yes — Shopify ties the merchant-of-record benefits to labels bought from a Managed Markets shipping service, not to your own negotiated rates.
- The stricter rule
- Shopify's shipping requirements rule out any other carrier for a Managed Markets order, Canada Post included
- What the loss covers
- Shopify lists tax remittance and duty handling as examples, so what you lose is an open set
- Connected carrier accounts
- A UPS or Canada Post account connected to your Shopify admin doesn't work on Managed Markets orders either
- Where your own carrier still works
- Among them: B2B orders, zero-value orders, switched draft orders, and any market you turn Managed Markets off for
- Where Managed Markets is available
- Merchants based in the continental United States, plus certain stores in Canada and the United Kingdom
What Shopify says you lose on your own carrier rates
Yes. Shopify makes the benefits conditional on where the shipping label came from, and says so about your own negotiated rates directly.
If you use your own negotiated rates with a third-party shipping service, then you don't get the benefits that Global-e acting as your merchant of record provides, such as: Remitting tax to local authorities / Managing duties and import tax.
Who handles that remittance and duty work instead is a question Shopify's Managed Markets pages do not answer: they describe the benefit you lose and stop there.
What exactly do you lose?
Tax remittance and duty handling, at least. Shopify lists them after the words such as, so what you forfeit is an open set rather than an exhaustive one.
The role is wider than that pair: the overview page also names commercial invoices and carrier arrangements among the parts Global-e handles, and our duties, taxes and merchant of record section covers the model.
Whether the loss is graduated is not something Shopify documents: no Shopify page we have found describes keeping one benefit while losing another — that reading comes off the Managed Markets shipping, overview and fulfillment pages, read on August 31, 2026.
Can you ship a Managed Markets order with another carrier?
Not by Shopify's rules. Its shipping requirements for Managed Markets are stricter than the note about lost benefits: you can't use any other shipping carrier to ship a Managed Markets order — Canada Post is the example Shopify gives — and you must fulfill international orders with one of the Managed Markets fulfillment options.
A UPS or Canada Post account you already connected to Shopify doesn't get around that. Shopify says Managed Markets isn't compatible with UPS accounts connected to your Shopify admin, and tells stores based in Canada the same about a connected Canada Post account: for those stores, each international order Managed Markets handles needs a DHL Express or FedEx label bought through it. For every other order, see whether you can use your own carrier account on Shopify.
If your store is in Canada and ships abroad with Canada Post, review your international rates before you activate: carrier-calculated rates are replaced by Managed Markets rates at checkout, while flat rates aren't changed automatically and can go on advertising a service you can no longer use for these orders.
Shopify states both things — you can't use another carrier, and your own negotiated rates cost you the benefits — and no page we read reconciles them: the Managed Markets shipping, shipping requirements, fulfillment, overview, Canada and United Kingdom pages, read on October 10, 2026. Plan around the stricter one.
How to keep the merchant-of-record benefits
Shopify states the condition in one line: buy labels only from one of the Managed Markets shipping services. Which of those services carry duty prepaid is a separate list that which services support DDP names.
In the admin that means buying the label on the order itself: open the order under Orders and click Create shipping label in its Unfulfilled section. A 3PL can buy these labels once it is one of the compatible fulfillment services Shopify lists and has completed the extra integration step; otherwise Shopify's immediate route is that you or the partner buy the label in your Shopify admin.
Keeping the benefits is not free either: Managed Markets charges a transaction fee that differs by plan, plus a currency conversion fee and a Shopify Payments processing fee. What those fees come to on an international order is priced in what Managed Markets adds to your Shopify bill.
The choice only matters where the product is open to you: Managed Markets is limited to merchants based in the continental United States, plus certain stores in Canada and the United Kingdom.
What to do if you already have negotiated carrier rates
Decide market by market. The three setups differ in who answers for tax and duties.
Three setups for an international order
| Setup | Who answers for tax and duties | Carriers you can use | Duties at checkout |
|---|---|---|---|
| Market on Managed Markets, label from its shipping services | Global-e, as merchant of record | The Managed Markets shipping services | Prepaid for most destinations; the amounts shown at checkout are guaranteed |
| Market on Managed Markets, your own negotiated rates | Not documented — only that you don't get Global-e's benefits | Ruled out by Shopify's shipping requirements | Not documented for this case |
| Market taken out of Managed Markets | You, as your own merchant of record | Your own carriers | If you set up Shopify's duties and import taxes feature — an estimate, not a guarantee |
Shopify Help Center, read on October 10, 2026.
The guarantee in the first row has its own condition: Shopify says your duties aren't guaranteed if a product's HS code or country of origin is inaccurate.
If the tax cover is worth more than your rate, keep the market managed and let the contract work elsewhere. Shopify says you can still use other carriers for domestic orders and for international orders where you are the merchant of record. B2B orders and zero-value orders fall there because Managed Markets doesn't support them; who the merchant of record is on a digital-only order is a separate question.
If the contract matters more in one market, turn Managed Markets off for that market and leave the others managed: in Markets, open the market and switch off the toggle in the Shopify Managed Markets section. From then on you are responsible for tax compliance and regulatory requirements there, shipping rates exclusive to Managed Markets stop being available, and Managed Markets no longer calculates duties and import taxes.
Orders placed while Managed Markets was active still need to be fulfilled through it, so the change doesn't free an order already in your queue.
Shopify's duties and import taxes feature, the replacement Shopify points to, collects an estimate for its own transaction fee and expects you to fulfill with a delivered duty paid label, which Shopify notes not all carriers support — so confirm your contract covers DDP to that market before you switch.
For a single order there is a narrower route, on draft orders: Change merchant of record in the draft's Market section moves it from Managed Markets to you, along with what Shopify calls the financial and legal complexities of international sales. The switch has to happen while the order is still a draft — what you can do with a SKU Managed Markets won't ship explains why.
What happens to the fee and the duties on your own rates?
Neither is documented on the Shopify pages we read. Shopify's Managed Markets pricing applies the fees to the order total of international orders, and the exemption it does state is the transaction fee on international B2B orders.
No Shopify page we read ties those fees to where the label was bought, or says what happens to duties a customer already paid at checkout when the parcel travels on your own account — the Managed Markets overview, pricing, shipping, shipping requirements and fulfillment pages, read on October 10, 2026.
The nearest documented case is the draft order: without a Managed Markets shipping method assigned, Shopify says duties aren't calculated and Managed Markets isn't assigned as the merchant of record. For a live order, don't budget on the fee disappearing, and ask Shopify Support before you ship — Shopify sends all Managed Markets questions there rather than to Global-e.
