Moltline Shipping Maths
Calculate dimensional weight, box fit, landed costs and freight class for shipping.
Helps small businesses and e-commerce sellers optimize shipping costs. Calculates dimensional weight vs actual weight, finds the smallest box an item fits in, computes landed costs with duty and tax, and estimates US LTL freight class from density. Four tools are free; rate card and free shipping threshold require a license.
Try asking Muse: "Tell me if this 18 by 12 by 10 inch box weighing 6 pounds will be billed on size or weight."

dim_weightWork out whether a parcel bills on its size or its weight. FREE. Carriers charge the greater of actual weight and dimensional weight, so a light bulky box costs more than the scale suggests. Typical input {"length": 18, "width": 12, "height": 10, "actual_weight": 6} returns {"cubparcel_fitPick the smallest box an item actually fits in, allowing for padding. FREE. Tries every rotation of the item against every box, so an item that only fits diagonally-oriented is still found. Typical input {"item_length": 10, "item_width": 6, "item_height": 4, "box_options": [[12, landed_costTotal what a unit really costs once freight, duty and fees are in. FREE. Duty is applied to goods value, tax to goods plus duty plus freight — the common import treatment — and the order is spelled out in the response so you can check it against your own broker's method. Typical freight_classDerive a US LTL freight class from density. FREE. Density in pounds per cubic foot maps to a class on the published NMFC density scale. Typical input {"length": 48, "width": 40, "height": 36, "weight": 400} returns {"cubic_feet": 40.0, "density_pcf": 10.0, "density_class": "100",rate_cardTurn a cost model into a customer-facing weight-banded price table. PREMIUM (license). Prices each band at its upper bound so you never under-charge inside a band, then rounds up to a tidy increment.
