Hey Product Hunt community! 👋 I built SinoScout (https://sinoscout.vercel.app/) to solve a huge headache every US Amazon FBA, TikTok Shop, and Shopify seller faces when sourcing from China. Many sellers try to bypass AliExpress or Alibaba middlemen by going directly to 1688.com. But in reality, nearly 70% of listings on 1688 are still domestic trading resellers marking up factory EXW prices by 25%–45%. On top of that, calculating exact US doorstep landed costs with USITC HTS duties, Section 301 China tariffs, and Air/Sea DDP freight per kg is messy. SinoScout is a 100% free, interactive browser tool that solves both sides of that equation: 1. 1688 True Factory Verifier: Scores supplier authenticity using 6 industrial belt signals (business license scope, buyer repurchase rate, and cluster geography) so you know if they own real manufacturing plants. 2. Native B2B Factory Script: Auto-generates a ready-to-send Chinese AliWangWang/WeChat inquiry script so factories quote you bulk EXW rates instead of retail prices. 3. HTS Landed Cost & Margin Simulator: Dynamically calculates your net margin and compares 1688 factory sourcing directly against AliExpress dropshipping. You can test it right away with 4 pre-loaded viral product teardowns (no login or credit card required). Would love to hear your feedback, feature ideas, or any questions about US-China cross-border supply chains! 🚀
