International Shipping Guide

International Shipping Guide

International shipping from the US adds three layers of complexity that domestic shipping doesn't have: customs declarations, duties and taxes, and country-specific import restrictions. Get the customs form wrong and your package sits in a foreign warehouse for weeks. Underdeclare the value and your customer gets hit with unexpected duty charges at delivery.

Here's a practical breakdown of what you need to know — from HS codes to carrier selection — to ship internationally without returns, delays, or angry customers.
