NMFC Code Lookup
Search NMFC commodity codes and freight classes for common freight types. Find the correct NMFC code before you book to avoid reclassification charges from your carrier.
How to use: Search by commodity name or NMFC code to find the correct classification, sub-codes, and class ranges. Results include density requirements and common packaging notes.
What is an NMFC code?
NMFC stands for National Motor Freight Classification. It is the standardized system that assigns a numeric code and freight class to every commodity shipped via LTL. The NMFC code determines how your freight is classified, which directly affects the rate your carrier charges.
Each NMFC code maps to a freight class between 50 and 500. The class is based on four characteristics: density, stowability, handling difficulty, and liability. In practice, density is the dominant factor for most commodities.
Why NMFC codes matter
Using the wrong NMFC code on your bill of lading is one of the most common causes of reclassification charges. When a carrier inspects your shipment at the terminal and assigns a different NMFC code than what you declared, they reclassify the shipment to a higher freight class and bill you the difference, often weeks after delivery.
Getting the NMFC code right at booking prevents these surprises. Use this lookup tool to find the correct code for your commodity, then verify it against the NMFTA classification database if needed.
Warp does not require NMFC codes
Warp prices by pallet, not by NMFC classification. You do not need to look up commodity codes, determine freight class, or worry about reclassification. Enter your pallet count, weight, and dimensions, and get an all-inclusive rate. The price at booking is the price you pay.
NMFC code FAQ
What is an NMFC code?
An NMFC (National Motor Freight Classification) code is a standardized numeric code assigned to every type of commodity shipped via LTL freight. Each code maps to a freight class (50-500) that determines shipping rates. The codes are maintained by the NMFTA.
How do I find my NMFC code?
Search by commodity description in the lookup tool above. If your exact commodity is not listed, look for the closest match or use the NOI (Not Otherwise Indicated) category. For official classification, consult the NMFTA ClassIT database or contact your carrier.
What does NOI mean in NMFC classification?
NOI stands for Not Otherwise Indicated. It is a catch-all classification for commodities that do not have a specific NMFC code. NOI codes are classified based on density, so the freight class depends on actual weight and dimensions.
What are NMFC sub-codes?
Sub-codes are variations within a single NMFC item number that assign different freight classes based on density ranges. For example, NMFC 116030 (furniture) has sub-codes 1 through 5, each mapping to a different class. Sub-code 1 might be Class 70 for dense pieces while sub-code 5 is Class 200 for lightweight items.
Can my carrier override the NMFC code I put on the BOL?
Yes. Carriers inspect freight at their terminals and can reclassify if the commodity does not match the declared NMFC code or if actual density falls into a different sub-code range. This triggers a reclassification charge billed after delivery.
Where does the official NMFC database come from?
The NMFC is published by the National Motor Freight Traffic Association (NMFTA) in Alexandria, Virginia. The official lookup tool is ClassIT+, which requires a paid subscription. This free tool covers common commodities, but the NMFTA database is the authoritative source.
What are the four factors that determine NMFC classification?
Density (weight per cubic foot, the dominant factor), stowability (how well freight fits with other cargo), handling difficulty (whether special equipment is needed), and liability (risk of damage, theft, or spoilage). For most general freight, density alone determines the class.
Do I need an NMFC code for FTL shipments?
No. NMFC codes and freight classes apply to LTL shipments only. FTL rates are based on lane distance, equipment type, and market conditions. You still need an accurate commodity description on the BOL for insurance and customs, but the NMFC code does not affect FTL pricing.
