Freight & Import Calculator Suite

Every tool on this site computes with published standards — ISO 668 container ratings, IATA Resolution 502 chargeable weight, WCO customs valuation, ICC Incoterms 2020 — and states its scope next to every result. Pick a calculator below; each page opens with the definition, the formula table, and the basis the math rests on.

All calculators run locally in your browser and store nothing.
