## What it does

The skill totals what a shipment really costs: FOB value, freight, insurance, duty, VAT or GST, customs clearance, port and inland fees, plus a per-unit figure. Routes cover China to the US and EU, the US to the EU and back, and China to the UK, Canada and Australia. Section 301 rates for Chinese imports into the US are built in, along with USMCA, EVFTA, RCEP and UK-Japan preferences.

Two Python scripts do the work. `scripts/calculator.py` takes a JSON payload with HS code, origin, destination, shipment value, quantity and freight; on an unusual route you supply your own duty and VAT rates. `scripts/hs_lookup.py` suggests an HS code from a product description. No API key is involved.

Rates sit in the skill files, so a wrong classification gives you a wrong total: the HS code drives the duty. For a route outside the table, leaving out `custom_duty_rate` and `custom_vat_rate` leaves the sum unfinished.
