Use a DDP (Delivered Duty Paid) provider such as Zonos or Global-e on Shopify, or the Easyship plugin on WooCommerce, to calculate and display duties as a checkout line item. Orders below the destination country's de minimis threshold are typically duty-free and should show no estimate.

In Shopify, enter the HS tariff code under Products → Shipping → Customs information, or bulk-fill the Variant HS Code column via CSV export/import. In WooCommerce, shipping plugins like Easyship add HS code fields, or you can store them as custom fields.

DDP (Delivered Duty Paid) collects duties at checkout so customers see the full landed cost upfront, while DDU (Delivered Duty Unpaid) makes customers pay duties on delivery. DDP generally converts better and reduces refused deliveries and returns.

No. Shopify Markets handles multi-currency and localized checkout but does not calculate duties. You need an app like Zonos Duty & Tax or Global-e to show accurate DDP landed costs at checkout.

The most common cause is missing HS codes or country of origin on product records, which prevents customs form generation. Ensure every product has a 6-10 digit HS code and that your shipping app always includes customs data for non-domestic destinations.

Screen carts at checkout, not at fulfillment, by matching each product's HS code prefix against a country restrictions list (e.g., firearm parts to Australia, alcohol to India). On Shopify, use Markets to disable specific countries per product; on WooCommerce, use a shipping restrictions plugin.
