International Shipping

If you're expanding beyond domestic shipping, you need to handle HS code assignment, customs form generation, and duties calculation or you'll have packages stuck in customs and angry customers hit with surprise fees. This walks through platform-specific setups for Shopify Markets with Zonos, WooCommerce with Easyship, and BigCommerce with Avalara to show DDP landed costs at checkout. It also covers bulk HS code assignment (critical for catalogs over 50 products) and how to block restricted items by destination country. The customs declaration details alone will save you from the nightmare of manually filling CN22 forms at the post office. Worth the advanced difficulty rating because getting tariff classification wrong has legal consequences.

International Shipping

Overview

International shipping requires more than just choosing a carrier — you need to handle customs declarations, duties and taxes (showing customers the landed cost at checkout prevents nasty surprises), HS code classification for each product, and screening for items that are prohibited in certain countries. Getting this wrong leads to packages stuck in customs, unexpected bills delivered to customers, and damaged brand reputation.

This skill walks through setting up international shipping on each major platform, including the right apps for duties/taxes and customs form generation.
