Hi Product Hunt 👋 I built CargoSum after years around ocean freight operations, where the same questions came up every day: how many of these cartons fit in a 40HC, what's the chargeable weight on this air shipment, will this go as one container or two? Most free tools I found either hid the answer behind a quote form or a sign-up, or only handled one box size at a time. So I made the calculators I wanted: • 3D container loading with mixed cargo (up to 50 item types), rotation rules, stacking limits, weight distribution and center of gravity • CBM, chargeable weight (air/express/LCL), pallet loading, NMFC freight class, LTL linear feet, fuel surcharge, demurrage • Everything runs locally in your browser, results update as you type, and any result can be shared as a link or exported to CSV It's free with no account, in English, German, Japanese and Korean. I'd love feedback from anyone who plans loads or quotes freight: what's missing, what's wrong, and which edge cases break the packer.
