Tool scope
Density-Based Planning Estimates Only
Freight Class Calculator provides density-based freight class and freight density estimates for packaged LTL shipment planning. The site does not provide official NMFC classification, carrier pricing, tariff interpretation, shipment booking, billing approval, or shipping advice.
Important classification boundary
Final freight class may depend on NMFC item number, commodity, packaging, handling, stowability, liability, carrier rules, tariff terms, and shipment-specific details. Confirm final class and billing requirements with your carrier, broker, or NMFC source before booking or billing.
User responsibility
Your Use of Calculator Results
You are responsible for entering accurate shipment dimensions, weight, quantity, units, and shipment details. Small measurement differences, pallet overhang, wrap, crating, carrier remeasurement, or reweighing can affect density and estimated class.
You agree not to rely on the site as the sole basis for freight classification, quoting, booking, billing, audit responses, or carrier disputes. Use the results as a planning reference and confirm shipment requirements with the appropriate carrier, broker, or classification source.
No professional relationship
No Carrier, Broker, or Advisory Service
Freight Class Calculator is not a freight carrier, freight broker, shipper, tariff publisher, legal advisor, billing service, or official NMFC classification provider. Use of this site does not create a carrier relationship, broker relationship, customer relationship, professional advisory relationship, or service agreement with Greenspark.Group LLC.
