International Shipping Calculator.
Every carrier. Any country.

International shipping pricing is much less consistent than US domestic. Each carrier has different bilateral postal agreements + network density in different regions, so the cheapest option varies wildly by destination country. That's exactly why a side-by-side quote matters - the winner for Canada is rarely the winner for Australia.

• USPS Priority Mail International

  Best for

  Lightweight parcels (under 4 lb) to most countries; cheapest entry-level option

  Watch out for

  Slower (6-10 business days); limited tracking once it leaves the US

• UPS Worldwide Expedited / Saver

  Best for

  Mid-weight parcels with delivery commitment; strong network in Canada + Mexico

  Watch out for

  More expensive than USPS for under-2-lb parcels to non-NAFTA destinations

• FedEx International Economy / Priority

  Best for

  Time-definite shipments to Asia + Latin America; reliable customs clearance

  Watch out for

  Premium pricing; rarely the cheapest option for any specific lane

• DHL Express Worldwide

  Best for

  Fast delivery to Europe, Middle East, Africa, parts of Asia; door-to-door tracking

  Watch out for

  Usually most expensive option; underwhelming on Canada + Mexico vs UPS

Beyond the rate quote, every international shipment requires a customs declaration. The calculator above quotes the carrier shipping cost only; when you actually print the label, you'll fill in three customs fields:

• Contents description- plain-English description of what's in the package (e.g. "2× cotton t-shirts"). Customs uses this to classify duty.
• Declared value - the commercial value of the contents in USD. Determines duty + VAT owed by the recipient.
• HS tariff code (optional but recommended) - the 6-digit Harmonized System code for the product category. Speeds clearance + reduces the chance of inspection holds.

shiponline.app suggests defaults for all three fields based on the items you've staged for the shipment - HS code from your saved item presets, contents description from item names, declared value from per-unit value × qty. You confirm or override with one click before printing.

Two billing models for international duty + tax:

• DDU (Delivered Duty Unpaid)- the default. The recipient pays duty + VAT to customs or the carrier on delivery before they can take the package. Cheapest for the sender; worst buyer experience because it's a surprise bill.
• DDP (Delivered Duty Paid) - you pre-pay the duty + VAT at label-print time. Slightly more expensive upfront but no surprise charges for the buyer, which improves repeat-purchase rates for e-commerce shippers.

DDP availability depends on carrier + destination. DHL and FedEx support DDP to most countries; USPS doesn't. The calculator quotes DDU pricing here - DDP is offered at label-purchase time when supported.

Carriers enforce stricter prohibited-item rules internationally than domestically. The full list varies by destination, but recurring restrictions to watch for: alcohol (banned by most carriers internationally), perishable food (banned via air), batteries (lithium shipments require dangerous-goods paperwork), and anything firearm-adjacent.

When you print a label, the buy flow asks you to attest that your shipment doesn't contain restricted items; false attestations void the label and can land you on a carrier no-ship list. When in doubt, search the carrier's published prohibited-items list before quoting.
