How to read your duty results

Understand what the postal and commercial totals mean.

When you run a calculation, you’ll see:
  • Postal duty total – the duty amount applicable to postal shipments under current U.S. rules.
  • Commercial duty total – the duty amount typically used for private carriers and commercial shipments.
  • Breakdown by rate type – including standard rates and any additional tariffs that may apply.
  • Per-shipment duty estimate – the amount you should plan to prepay before your parcel enters the U.S.

What to do with this information

Use the duty estimate to meet U.S. requirements and set prices correctly.

After you calculate duties, you can:
  • Include the duty amount before mailing your parcel to the U.S.
  • Build duties into your product prices when selling to U.S. customers.
  • Communicate the duty cost to the recipient ahead of time.
  • Use the estimate as part of your overall landed cost for international pricing.
