Summary
If you're selling on Amazon internationally, this handles the math you'd otherwise be fumbling through spreadsheets for. It calculates landed costs across major trade routes (China to US, EU, UK, plus custom pairs), factors in Section 301 tariffs on Chinese goods, and handles VAT/GST by country. The HS code lookup is handy since product classifications are never obvious. Works offline without API keys, which is nice when you're just modeling scenarios. Output is clean and detailed enough to actually use for pricing decisions. Built for sellers who need real numbers fast, not customs brokers who live in this stuff daily.
