Prepare your shipment with confidence before the surprises show up.
Estimate HS codes, sanity-check duty and landed cost, and generate broker-ready documents you can share. Built for real workflows, not theory.
Best used when:
- You’re planning your first shipment (or switching suppliers)
- A broker asks for HS codes, product details, or documents
- You want a duty/landed cost sanity-check before wiring money
- You’ve been burned by “we missed one thing…” delays
Not legal advice. StormScale is designed to help you prepare better conversations with brokers and forwarders — and avoid avoidable back-and-forth.
Used by small importers, students, and lean trade teams prepping shipments before speaking to customs brokers.
Built in British Columbia, Canada — for people who live in spreadsheets: import/export coordinators, e-commerce sellers, brokers-in-training, and trade students.
Tools in beta
Small, opinionated utilities you can layer on top of the spreadsheets and systems you already use.
