OVERVIEW Shipping and landed-cost arithmetic on your own inputs — no carrier account, no rate contract, no live quotes. Dimensional weight, the smallest box that fits, landed cost with duty and tax in a stated order, an LTL freight-class estimate; with a licence, a weight-banded rate card and the free-shipping threshold that stops costing you money.

KEY CAPABILITIES • dim_weight — billable weight, whether the parcel bills on size or weight, and the overage • parcel_fit — the smallest box an item fits in, trying every rotation, with padding • landed_cost — goods, duty, freight and tax rolled up to a landed unit cost, with the order of operations spelled out • freight_class — a US LTL class from density on the NMFC density scale (a first estimate; carriers can reclassify) • Licence: rate_card (customer-facing weight bands priced at the upper bound) + free_shipping_threshold (break-even and a suggested threshold above your current AOV)

USE CASES • Decide whether a smaller box is worth the packing effort • Set a landed unit cost before pricing an import • Publish shipping bands that never under-charge inside a band

WHO THIS IS FOR E-commerce operators, 3PL planners and the agents that quote shipping for them.
