Go to Settings > Taxes and duties in the Shopify admin and enable 'Collect duties and import taxes at checkout' for the relevant market
Ensure all products have Harmonized System (HS) codes applied and country-of-origin set so Shopify can calculate accurate duty rates
Use a shipping carrier that supports DDP labels (e.g., DHL Express or DHL eCommerce) so Shopify can purchase Delivered Duty Paid labels from the admin
Verify the transaction fee (currently 0.5% for duty calculation) is accounted for in your margin model
Test with a buyer address in a target country and confirm duty and tax amounts appear as a line item at checkout before payment
After go-live, monitor the order's duty fields in the Admin GraphQL API Order object to reconcile collected amounts against remittance
Known gotchas
Managed Markets DDP coverage and carrier availability differ by destination country; not every country is supported, so check the eligibility list before enabling globally
As of August 2025, US de minimis no longer applies, meaning duties apply to all US imports regardless of shipment value — update your product HS code coverage accordingly
Turning on duty collection without complete HS codes causes checkout errors or falls back to estimated amounts, which can create reconciliation issues
