Key Takeaways
- Shopify announced on August 11, 2026 that Managed Markets would end DDU from August 24 in countries and regions supporting DDP.
- Markets using or inheriting DDU automatically switch to DDP within the supported scope, with buyers paying duties and taxes at checkout.
- Merchants wanting buyers to keep paying on delivery need to turn off Shopify Managed Markets. This is not a DDU switch on an individual order.
- Check market inheritance, checkout duties and taxes, product HS codes and origin before deciding to keep DDP or exit Managed Markets.
- Stop bulk fulfillment and preserve evidence if taxes are zero, label terms disagree or checkout charges differ markedly from carrier charges.
New checkout duties do not necessarily mean price configuration is broken
A typical scenario is an operator reviewing US, EU or other cross-border markets and seeing duties or import taxes at checkout for orders that previously expected payment on receipt. Visible effects include a higher landed price, customer questions or mistaken suspicion of duplicate tax-app charges. The cost goes beyond one drop in conversion: casually disabling taxes to restore the old display while labels and commercial invoices use different terms can charge buyers again at delivery and make support, refusal and refund responsibility hard to trace.
The wrong instinct is to change product prices, remove shipping rates or reinstall apps first. Leave production settings alone, open an unsubmitted test checkout for an affected market, record products, destination country, tax lines and time, then inspect whether that market uses or inherits Managed Markets.
Old and new rules: payment timing and responsibility change
Under DDU (Delivered Duty Unpaid), recipients generally bear duties and import taxes at delivery or customs clearance. Under DDP (Delivered Duty Paid), merchants handle these charges in advance through checkout and fulfillment. Shopify confirms that from August 24, 2026, Managed Markets ends DDU in every country and region where it already supports DDP. Configurations using DDU or inheriting it from a parent market automatically change to DDP.
This does not force DDP on every Shopify store, carrier and country worldwide. The announcement concerns Shopify Managed Markets and only its DDP-supported countries and regions. Ordinary international markets outside Managed Markets, external carrier accounts and unsupported destinations must be checked against their own configurations and carrier capabilities.
Decide first: retain Managed Markets or let buyers pay on delivery
Merchants suited to retaining DDP generally want buyers to see a more complete landed cost at order time and are willing to maintain product classification, HS codes, origin and tax reconciliation. Instead of searching for an obsolete DDU switch, focus on consistency among checkout estimates, labels and commercial invoices.
If the business requires recipients to bear duties at delivery, Shopify’s announcement offered turning off Managed Markets before August 24. Since that date has passed, first inspect current state and unfulfilled orders, then assess the consequences of leaving. Disabling Managed Markets may also change international pricing, tax collection, checkout and fulfillment, and is not merely a tax-display switch.
Seven post-migration checks
First, list every market enabling or inheriting Managed Markets. Second, create an unsubmitted test checkout for each major destination. Third, inspect duties and import taxes in order details. Fourth, sample product HS codes, country or region of origin, discounted prices and quantities. Fifth, verify the intended carrier and labels support DDP. Sixth, have tax, logistics and support teams agree on updated buyer explanations. Seventh, compare checkout collections, commercial invoices and carrier bills on a small number of real orders.
Record test products, destinations, market configuration, duties and taxes, shipping charges, label terms and verification time. Do not extrapolate one country’s result to all markets or assume checkout alone proves customs charges are accurate. Official guidance says duties and taxes are estimates based on information at order time; incorrect HS codes or origin can still cause adjustments.
Labels, invoices and orders must use the same facts
If checkout already collected duties and import taxes, use supported DDP labels during fulfillment and mark commercial invoices DDP. HS codes, origin, discounted prices, quantities and collected taxes must agree across orders, labels and invoices. Collecting taxes at checkout but using ordinary or payment-on-delivery labels may charge buyers again at delivery.
Conversely, do not force an order with no collected duties into DDP merely to bypass a label error. Check destination support, order tax lines and carrier service first. If the carrier does not support the required label, purchase a label externally, refund or pause fulfillment as appropriate under Shopify and carrier rules.
When to stop and when to revisit configuration
Stop bulk shipping if any of these occurs: affected-market checkout lacks expected duties; the same product and destination repeatedly produce markedly different estimates; label tax terms disagree with the order; HS codes or origin are missing; support cannot explain payment timing; or old orders remain unfulfilled after Managed Markets is disabled. Preserve order number, market, time, screenshots and carrier errors, then assess orders individually.
After carrier bills arrive for the first orders, compare checkout estimates with destination customs charges and review periodically. For significant differences, correct product and market data rather than hiding taxes or raising prices blindly. If the network cannot open Admin, label pages or official documentation, first use the proxy connection troubleshooting checklist to separate DNS, TLS, authentication and platform responses. Resume tax assessment after connectivity recovers.
Common misconceptions: DDP does not eliminate every customs risk
The first misconception is that DDP prevents all tax adjustments; estimates still depend on product information and customs processing. The second is that every Shopify store is forced to switch; this change is limited to Managed Markets destinations supporting DDP. The third is that leaving Managed Markets leaves every other international setting unaffected; review pricing, markets, labels and existing orders before exit.
The fourth is blaming every checkout anomaly on IPs or proxies. Whether tax lines appear is mainly determined by market, product and destination; the network affects page accessibility. If an account environment needs stable egress, visit the PuppyIP website for service information, but do not replace duties and fulfillment checks with an IP change.

Frequently Asked Questions
When did Shopify Managed Markets end DDU?
The official announcement was August 11, 2026, and the change took effect from August 24, 2026 in countries and regions where Managed Markets already supports DDP.
What happens to markets previously set to DDU?
Within the supported scope, markets using or inheriting DDU automatically switch to DDP, with buyers paying duties and taxes at checkout.
Can buyers still pay duties when they receive the goods?
Shopify’s announced path is to turn off Managed Markets. Since the effective date has passed, first check current markets and unfulfilled orders, then assess the overall effect on pricing, checkout and fulfillment.
Why can duties still change after switching to DDP?
Estimates use product and destination information at order time. Inaccurate HS codes, origin, prices or quantities can cause carrier or customs adjustments.
Can I use DDU labels if checkout collected taxes?
Do not mix them. When checkout has collected duties and import taxes, verify and use supported DDP labels so orders, labels and commercial invoices agree.
Should I change IP addresses first when tax lines are missing?
No. Check Managed Markets scope, market inheritance, destination and product customs information first. Investigate the network separately only if the page itself is inaccessible.
