• Shipments requiring guaranteed delivery dates
• Countries where USPS tracking is unreliable

FedEx International

Best for:

• Fast delivery (FedEx International Priority: 1-3 days)
• Shipments to remote areas (better global coverage than UPS)
• Documents and envelopes (FedEx International Economy for docs: $25-$40)

DHL Express

Best for:

• Shipments to Europe, Asia, and the Middle East (DHL dominates these regions)
• Express delivery with customs clearance included
• International e-commerce (DHL has the best customs brokerage)

Understanding Customs and Duties

What Are Customs Duties?

When a package arrives in another country, the recipient may need to pay import duties (taxes) on the contents. These are NOT shipping charges — they're government taxes.

Duty-Free Thresholds by Country

Customs Forms

Every international package requires a customs form:

• CN22 (USPS): For packages valued under $400
• CN23/CP72 (USPS): For packages valued $400+
• Commercial Invoice: Required by UPS, FedEx, and DHL for all shipments

What to include:

• Accurate description of contents (be specific — "cotton t-shirt" not "clothing")
• Quantity and value of each item
• Country of origin (where the item was manufactured)
• HS tariff code (optional but speeds up customs clearance)
