The Zonos app (formerly Zonos Prepay) allows you to prepay duties on international postal shipments. Snap a photo, AI auto-fills customs details (or enter your own), check for import compliance, pay in your currency, and get a QR code/Declaration ID for U.S. shipping. Easily calculate and prepay U.S. duties with the Zonos app. Just snap a picture of the items you’re shipping, and our AI fills in the customs details for you, including calculating duty cost. Review/edit the information, pay instantly in your own currency, and ship with confidence. Prefer to enter your item information manually? That’s supported too (no photo required). Zonos app guide: https://zonos.com/docs/postal/tools-for-shippers/zonos-prepay). Why Zonos: - Free account (no subscription costs). - Prepay duties when required to continue shipping postal to the U.S. - Save time with auto-filled customs declarations based on a quick photo (or manually enter the item information yourself, if preferred) - Get accurate, guaranteed duty and tax totals with HTS codes. Neither you nor your recipient will have to pay additional duties, even if customs re-assess your shipment. - Pay as you go: Pay a clearance/processing fee per shipment, along with the duty cost - Get a QR code & Declaration ID for smooth shipping. - 27 languages, local currencies and payment methods. How It Works: 1. Create a free account. 2. Select the post you are shipping with. 3. Click “Add items manually” to enter your item information yourself, or click “Take a picture” to take a photo and have the app auto-populate your item information. You can include all items in one photo, or take multiple photos. Note: Only include items that are shipping within the same box. If you are shipping multiple boxes, only enter and pay for one box at a time, so you get a Declaration ID for each box. 4. Review/edit the item information, then click “Calculate duties” to get the duty costs and associated processing/clearance fees for your shipment. 5. Pay in your own currency. Payment covers both duties and the clearance/processing fee. 6. Present your QR code/Declaration ID at drop-off to confirm duties are prepaid. If you have questions, please contact our support team at support@zonos.com. Who It’s For: Individuals and small businesses shipping to the United States, plus postal operators needing a compliant prepayment solution. Compliance Note: U.S. regulations require prepaid duties for postal shipments under $2500 USD (effective Jul 24, 2026). Zonos Prepay ensures compliance and eliminates delays.
