Logistics arithmetic computed locally from the inputs given, provided as is. Carrier divisors, container dimensions and weight limits vary by carrier, line and year: every endpoint lets you override them and states the assumption used. Packing counts are simple grid layouts, a lower bound on what a skilled packer achieves. Not a carrier quote, customs or tax advice. Every paid response carries a disclaimer field.
