Integrate Zonos With Your Shipping Software

The ShipStation and Zonos integration helps you run cross-border fulfillment with less friction. Zonos handles key international commerce data like duties, taxes, and tariff classification, while ShipStation helps you manage shipping and create labels in the same workflow. That gives your team one clearer path from international order to outbound shipment. It also helps you create a better buyer experience by reducing surprise fees at delivery.

Yes. Zonos is built to calculate duties, taxes, and other landed-cost inputs for international orders, and ShipStation gives you the shipping workflow to act on that order data. This is especially useful for DDP shipping, where customers pay duties and taxes up front instead of getting hit with charges later. The result is a cleaner checkout-to-fulfillment flow and fewer cross-border headaches for your team.

Rejected packages often start with surprise costs. Zonos helps you present duties, taxes, and related fees up front, so customers have more clarity before the shipment arrives. ShipStation then helps you keep fulfillment organized once the order is ready to ship. Together, that means:

• Clearer landed-cost visibility
• Stronger support for DDP shipping
• Less manual quoting for international orders
• Fewer delivery surprises for customers

Yes. Zonos supports tariff and HS code classification as part of its cross-border workflow, and ShipStation supports customs declarations for international shipping. There is one key detail to know: Harmonized Tariff Codes are not imported from Zonos into ShipStation for international orders. In ShipStation, you can add those codes to product records or customs declarations. **Tip:** Add tariff codes to product records if you ship the same items internationally on a regular basis.

It depends on where the order came from. For merchants that use Zonos with Shopify or BigCommerce, Zonos can send shipment information from ShipStation back to those stores. For other marketplaces connected to Zonos, tracking does not update automatically. In those cases, you need to upload the tracking number and update the order status in the marketplace directly.

Yes. If your international shipping workflow includes UPS, Zonos and ShipStation fit into that broader carrier-based process. Zonos focuses on cross-border duty, tax, and compliance data, while ShipStation gives you a multi-carrier shipping workflow built to manage labels and fulfillment. That separation matters because you don’t need to treat customs data and daily shipping operations as two disconnected jobs.

Yes. This setup is a strong fit when your business is moving beyond occasional cross-border orders and needs a more repeatable process. Zonos helps bring order to landed costs and compliance work, while ShipStation helps you scale fulfillment with automation, broad carrier access, and multi-channel control. It’s especially useful if your team wants to reduce manual shipping work, create a smoother DDP experience, and grow international sales without adding more operational chaos.
