How to Create International Shipping Labels

Everything you need to know about customs forms, carrier options, and label requirements for shipping worldwide.

Shipping internationally requires more than just a standard label. You need customs declarations, accurate value descriptions, and the right carrier service to ensure your package clears customs and arrives safely. This guide covers the entire process.

What Makes International Labels Different

Every international shipment requires a customs declaration form attached to the package. This tells the destination country what's inside, how much it's worth, and whether it's a gift, commercial shipment, or returned goods. Without proper customs documentation, your package will be delayed or returned.

The key elements of an international shipping label include:

Full sender and recipient addresses (including country)
Customs form (CN22 or CN23) with item descriptions
Declared value and currency
HS tariff codes (harmonized system codes for item classification)
Country of origin for each item
Contents type (merchandise, gift, documents, returned goods)

Customs Forms: CN22 vs CN23

CN22: A small customs declaration for packages valued under $400 and weighing under 4 lbs. It's a simplified form with basic item descriptions.
CN23: A detailed customs declaration required for packages valued over $400 or weighing over 4 lbs. Requires full item descriptions, quantities, weights, and values.
Commercial Invoice: Required by UPS, FedEx, and DHL for all commercial shipments. Includes detailed product information, buyer/seller details, and terms of sale.

How to Create Your International Label

Enter addresses: Include the full destination address with postal code and country name. Use the local format when possible.
Describe contents accurately: Vague descriptions like “merchandise” or “stuff” will cause customs delays. Be specific: “cotton t-shirt,” “ceramic mug,” “handmade jewelry.”
Declare accurate values: Under-declaring values to avoid duties is illegal and can result in seized packages or fines.
Include HS codes: Harmonized System codes classify your items for customs. Look up codes at hts.usitc.gov.
Print and attach: Print the label and customs forms, place them in a clear customs pouch (for USPS) or attach per carrier instructions.

Common International Shipping Mistakes

Missing customs forms: The package will be returned. Always include them.
Incomplete addresses: Include the recipient's phone number — customs agencies often call the recipient to arrange delivery or payment of duties.
Shipping prohibited items: Each country has its own restrictions. Check the USPS or carrier website for destination country prohibitions before shipping.
Ignoring duties and taxes: The recipient may owe import duties on arrival. Set expectations with your buyer upfront.
