USPS offers several international shipping services to more than 180 countries, ranging from budget economy options to guaranteed express delivery.

Customs Forms: What You Need to Know
All international packages require customs declarations. USPS has simplified this process — customs forms are now created electronically when you purchase international postage online. Here's what information you'll need to provide:
- Full name and address of sender and recipient
- Detailed description of contents (be specific — "gift" is not sufficient)
- Quantity and value of each item in USD
- Country of manufacture for each item
- HS (Harmonized System) tariff code, if applicable
- Whether the package is a gift, merchandise, returned goods, or a sample
Tip: Always be accurate on customs forms. Incorrect declarations can cause delays, seizure of goods, or fines at the destination country's customs office.
Prohibited and Restricted Items
Different countries have different rules about what can be imported. Common universally prohibited items for USPS international shipments include:
- Lithium batteries shipped alone (restrictions apply)
- Aerosols and flammable liquids
- Perishable food items (without proper documentation)
- Currency and money orders (in most cases)
- Controlled substances
Always check the USPS International Mail Manual (IMM) or the destination country's customs restrictions before shipping. The USPS website provides a country-by-country guide at pe.usps.com.
Tips for Smooth International Shipments
- Use exact addresses: Include postal codes, province/state names, and country written in English.
- Pack securely: International packages endure longer transit and more handling than domestic ones.
- Keep your receipt: You'll need the customs number if you need to file a claim or inquiry.
- Check delivery standards: Estimated delivery times can vary significantly based on local postal system efficiency at the destination.
- Consider insurance: For valuable items, purchase additional insurance beyond what's included in the service.
Tracking International Packages
International tracking depends heavily on the destination country's postal service. Priority Mail Express International and GXG generally offer the most reliable end-to-end tracking. For economy services, tracking often only shows departure from the US and final delivery scan, if available.
