2025 scale
| Commodity | Category | Basis | Typical density | Class span | Reclass risk | Guide |
|---|---|---|---|---|---|---|
| Aluminum extrusions Aluminum extrusions are lighter than steel but still dense enough to rate well. Long lengths, protective wrap, and the difference between mill finish and finished profiles drive the handling. | Metals & hardware | Density | 20–40 lb/ft³ | Class 55–70 | Low | Guide |
| Auto parts Auto parts range from dense brake rotors to bulky body panels. The class depends on the part, the packaging, and whether the shipment is new, used, or remanufactured. | Automotive | Mixed | 10–20 lb/ft³ | Class 70–92.5 | High | Guide |
| Bicycles Bicycles ship assembled or boxed, and the two are very different handling units. A boxed bike is light for its cube; an assembled bike is awkward, fragile, and often high-value. | Retail, sport & outdoor | Mixed | 4–8 lb/ft³ | Class 100–175 | High | Guide |
| Bookcases Bookcases are light for their height and easy to tip. The density question is usually about packaging and whether the unit ships assembled, flat-packed, or with glass shelves. | Furniture & fixtures | Mixed | 4–8 lb/ft³ | Class 100–175 | High | Guide |
| Bottled water Bottled water is heavy, stable, and usually easy to classify. The main variables are the case count, the pallet pattern, and whether the shipment is shrink-wrapped or in trays. | Food & beverage | Density | 25–35 lb/ft³ | Class 55–65 | Low | Guide |
| Boxed clothing Boxed clothing is light for its cube unless it is compressed or densely packed. Carton size, fold method, and the number of units per carton drive the density. | Apparel & textiles | Density | 5–10 lb/ft³ | Class 92.5–175 | Medium | Guide |
| Bumpers Bumpers and body panels are bulky, fragile, and easy to scratch. The class usually turns on the carton or crate and on whether the parts are nested or shipped individually. | Automotive | Mixed | 4–8 lb/ft³ | Class 100–175 | High | Guide |
| Canned goods Canned goods are dense, stackable, and usually straightforward. The class depends on the can size, the case pack, and whether the pallet is a mixed SKU load. | Food & beverage | Density | 30–45 lb/ft³ | Class 55–60 | Low | Guide |
| Clothing on hangers Clothing on hangers needs a garment box or rack, which adds cube without much weight. That packaging usually pushes the shipment into a lighter, more expensive class. | Apparel & textiles | Mixed | 2–5 lb/ft³ | Class 175–250 | High | Guide |
| Computers & servers Computers and servers are dense for electronics, especially when rack-mounted or crated. The class usually depends on the rack, crate, and whether the shipment includes monitors and accessories. | Appliances & electronics | Density | 8–15 lb/ft³ | Class 70–100 | Medium | Guide |
| Corrugated boxes (KD) Knocked-down corrugated boxes are light and bulky, and they nest into bundles that can be much denser than the cartons they become. Bundling is the density lever. | Paper & packaging | Density | 4–8 lb/ft³ | Class 100–175 | High | Guide |
| Drywall Drywall is heavy, brittle, and usually shipped in large flat units. Density is high and stable, so the class is rarely a surprise — but damage and handling are. | Building materials | Density | 40–55 lb/ft³ | Class 50–55 | Low | Guide |
| Fabric rolls Fabric rolls are denser than finished clothing and usually easier to rate. Roll diameter, length, and the way the rolls are racked or stacked decide the handling unit. | Apparel & textiles | Density | 8–15 lb/ft³ | Class 70–100 | Low | Guide |
| Fasteners Fasteners are small, dense, and usually packed in cartons or pails on a pallet. Density is high and stable; the main risk is losing the specific item description in a generic hardware shipment. | Metals & hardware | Density | 100–250 lb/ft³ | Class 50 | Low | Guide |
| Flat-panel TVs Flat-panel televisions are light, fragile, and shipped in cartons that are much larger than the screen. The carton and pallet usually decide the density, not the panel size alone. | Appliances & electronics | Density | 3–7 lb/ft³ | Class 125–250 | High | Guide |
| Foam products Foam is one of the lightest freight commodities. Density depends almost entirely on compression and packaging, and the class can move several tiers with a tighter bundle. | Plastics & chemicals | Density | 1–3 lb/ft³ | Class 250–300 | High | Guide |
| Frozen foods Frozen food is dense and usually easy to rate, but the shipment only works if the cold chain holds. Temperature service, loading time, and pallet configuration matter more than the class. | Food & beverage | Density | 20–35 lb/ft³ | Class 55–70 | Low | Guide |
| Generators Generators are heavy, dense machinery, and fuel residue can make them regulated. The class is usually favorable; the pre-booking questions are about weight, lift equipment, and hazmat status. | Machinery & industrial | Mixed | 12–22 lb/ft³ | Class 70–85 | Medium | Guide |
| Hospital beds Hospital beds are large, heavy, and often shipped knocked down or in sections. The handling unit, not the bed frame, decides the measured cube and the class. | Medical & lab | Mixed | 4–8 lb/ft³ | Class 100–175 | High | Guide |
| HVAC units HVAC equipment is bulky, fragile, and often shipped on a skid or in a crate. The class depends on the unit type and how much packaging surrounds the coil and cabinet. | Machinery & industrial | Mixed | 6–12 lb/ft³ | Class 85–125 | High | Guide |
| Insulation Insulation is extremely light for its cube, so it usually lands in the most expensive density tiers. Compression and packaging are the difference between a full load and a costly one. | Building materials | Density | 0.7–2 lb/ft³ | Class 250–400 | Medium | Guide |
| Lead-acid batteries Lead-acid batteries are dense and potentially regulated. The class is only part of the story: acid, venting, and hazardous-materials rules can decide whether the shipment moves at all. | Automotive | Mixed | 40–70 lb/ft³ | Class 50–55 | High | Guide |
| Lumber Lumber is dense and stable, so density is rarely the hard part. The classification question is usually the species, grade, treatment, and whether the load ships as loose boards, a bundle, or a unit. | Building materials | Density | 25–40 lb/ft³ | Class 55–65 | Low | Guide |
| Mattresses Mattresses are bulky and light for their cube, so packed density usually lands in the low single digits. Compression, pallet height, and overhang move the result more than the mattress type. | Furniture & fixtures | Density | 2–4 lb/ft³ | Class 175–250 | High | Guide |
| Medical devices Medical devices are high-value and fragile, and the packaging is often a substantial part of the shipment. Density is secondary to securement, liability, and handling instructions. | Medical & lab | Mixed | 6–12 lb/ft³ | Class 85–125 | High | Guide |
| Paint Paint is dense and often regulated. The class is usually favorable, but the hazmat status of the paint and any solvents can decide the carrier and the paperwork. | Plastics & chemicals | Mixed | 40–60 lb/ft³ | Class 50–55 | Medium | Guide |
| Paper towels & tissue Paper towels and tissue are extremely light for their cube. The class is usually expensive, and compression, baling, and packaging are the only meaningful levers. | Paper & packaging | Density | 1–4 lb/ft³ | Class 175–300 | Medium | Guide |
| Pharmaceuticals Pharmaceuticals are high-value, often temperature-sensitive, and heavily regulated. Density is only one input; chain of custody, temperature control, and liability usually decide the service. | Medical & lab | Mixed | 10–20 lb/ft³ | Class 70–92.5 | High | Guide |
| Plastic resin Plastic resin ships as dense pellets in bags, boxes, or bulk containers. Density is high and stable, and the main variables are packaging, moisture protection, and unloading equipment. | Plastics & chemicals | Density | 30–45 lb/ft³ | Class 55–60 | Low | Guide |
| Plywood Plywood is dense and ships in flat, stackable units. Density is stable, but the number of sheets per unit and the way the unit is banded can change the measured cube. | Building materials | Density | 30–45 lb/ft³ | Class 55–60 | Low | Guide |
| Printing paper Printing paper is dense, heavy, and moisture-sensitive. The class is stable; the handling unit, skid height, and protection from water are the practical variables. | Paper & packaging | Density | 40–55 lb/ft³ | Class 50–55 | Low | Guide |
| Pumps & compressors Pumps and compressors are dense, irregular machinery. The class depends on whether the unit is crated, skidded, or shipped with accessories, fluids, and controls attached. | Machinery & industrial | Mixed | 10–20 lb/ft³ | Class 70–92.5 | Medium | Guide |
| Refrigerators Refrigerators are bulky and surprisingly light for their size. Density depends on the crate or carton, the pallet, and whether the unit ships upright with doors and shelving installed. | Appliances & electronics | Mixed | 2–5 lb/ft³ | Class 175–250 | Medium | Guide |
| Sofas & sectionals Upholstered seating is bulky and easy to under-measure. A sofa that ships assembled, knocked down, or as a modular sectional can land in different density bands. | Furniture & fixtures | Mixed | 4–7 lb/ft³ | Class 125–175 | High | Guide |
| Steel plate & bar Steel plate and bar are among the densest common freight commodities. Density is not the uncertainty; the form, dimensions, and securement are. | Metals & hardware | Density | 100–300 lb/ft³ | Class 50 | Low | Guide |
| Tires Tires are bulky and awkward, and new, used, and baled tires can follow different classification paths. Density depends heavily on whether the tires are loose, stacked, banded, or baled. | Automotive | Mixed | 8–15 lb/ft³ | Class 70–100 | High | Guide |
| Toys Toys are packaged for retail, which means colorful cartons, display units, and a lot of air. Density is usually low, and packaging variation is the main reclass risk. | Retail, sport & outdoor | Density | 4–10 lb/ft³ | Class 92.5–175 | High | Guide |
| Washers & dryers Washers and dryers are dense appliances with a compact footprint. The class usually depends on whether the unit ships in its retail carton, in a crate, or on a shared pallet with other appliances. | Appliances & electronics | Mixed | 5–9 lb/ft³ | Class 100–175 | Medium | Guide |
| Wine Wine is dense for its cube but fragile and often temperature-sensitive. The class is usually manageable; the licensing, temperature, and breakage rules are the hard part. | Food & beverage | Density | 25–35 lb/ft³ | Class 55–65 | Medium | Guide |
| Wood cabinets Cabinets are dense for furniture but awkward to pack. Assembled cabinets, flat-pack cabinets, and vanity tops can follow different density paths and different NMFC items. | Furniture & fixtures | Mixed | 5–9.5 lb/ft³ | Class 100–175 | High | Guide |

How to read itHow to read a result
How to read an NMFC lookup result
Four fields, one honest answer. The directory is deliberately short on certainty and long on the questions that change a rating. Here is what each column means.
Back to the directoryBasis
Density-rated means the 2025 scale usually sets the class. Mixed means some forms carry a fixed item or a special provision. The item number decides which path applies.
Typical density
A planning estimate for packed pounds per cubic foot, not a measurement of your shipment. The confidence label tells you how tight the estimate is.
Class span
The classes touched by the endpoints of the typical density range, derived from the 13-tier scale. It is a span, not a prediction that every shipment lands in every class.
Reclass risk
How likely a second measurement is to land in another band. High risk means photograph the pallet, measure the full handling unit, and keep the BOL description specific.
Common searches
Common NMFC lookup searches
Most people arrive with a product and a question, not a tariff. The pattern behind the query matters: a palletized product, a specific item, a material and form, or a machine. Each row starts with the closest guide and names the variable that changes the answer.
Query · starting guide · what changes the answer
Lookup paths, not item numbers
| Common search | Start with | What changes the answer |
|---|---|---|
| NMFC code for auto parts on pallets | Auto parts | New, used, or remanufactured; boxed filters versus dense castings; pallet pattern and gross weight. |
| NMFC code for bottled water on pallets | Bottled water | Bottle size, case count, shrink wrap or trays, and the weight limit for a full pallet. |
| What is the NMFC code for commercial refrigerators? | Refrigerators | Household versus commercial refrigeration; carton versus crate; whether the unit can be stacked or must stay upright. |
| What is the NMFC code for metal shelving? | Bookcases | The nearest guide covers bookcases; shelving and racking are a different item. Assembled versus knocked down and metal versus wood matter. |
| NMFC code and freight class for lithium batteries | Lead-acid batteries | Chemistry and hazmat status come before class. Lithium is not lead-acid; confirm carrier acceptance and shipping papers. |
| NMFC code for plastic rolls | Plastics & chemicals | Film or sheet in rolls is not resin pellets or foam. Roll diameter, core, and wrap define the handling unit. |
| NMFC code for steel tubing | Steel plate & bar | Tube and pipe are distinct from plate and bar. Bundle dimensions, weight, and securement matter. |
| NMFC code for corrugated boxes knocked down | Corrugated boxes (KD) | Nesting and banding change density; a bundle and a pallet are different handling units. |
| NMFC number for industrial air compressor | Pumps & compressors | Crated versus skidded, accessories, and fluids. Measure the crate, not the bare machine. |
| NMFC number for forklift attachments | Machinery & industrial | An attachment is not the forklift or its battery. Crating, lift points, and weight distribution decide the handling unit. |

These are lookup paths, not item numbers. The exact NMFC item depends on the form, packaging, and carrier tariff. Confirm it in ClassIT+ or with the carrier before booking.
Read the verification guideThe item number is the authority
Why this NMFC lookup does not publish item numbers.
The NMFC is a licensed publication, not a free public list. The 2025 docket consolidated roughly 2,000 listings, so many codes circulating online are stale or describe a different packaging form. A class span can help you plan, but the item number is what the carrier and the tariff actually use.
People use “NMFC code,” “NMFC number,” and “item number” interchangeably. In the NMFC, the item number is the listing; the class is the rating.
We do not publish NMFC item numbers from memory or from a public list that may predate the 2025 consolidation. A wrong item number on a BOL is worse than no number. Confirm the current item in ClassIT+ or with the carrier before booking.
Four-step verification path
- Describe the freight as tendered. Assembled or knocked down? New or used? Boxed, baled, crated, or loose?
- Find the item. Search ClassIT+ by the commodity description, or ask the carrier to confirm the item and class.
- Check the density provision. Some items use the generic 13-tier scale; others carry a fixed class or a density subprovision.
- Put it on the BOL. Add the item number, description, handling-unit count, gross weight, and dimensions. Keep photos.

The scale behind the spans
Freight class codes list: 13 tiers effective July 19, 2025
The 2025 scale runs from Class 50 to Class 400. Classes 77.5, 110, 150, 200, and 500 still exist for commodity-specific items, but a density lookup never returns them. The chart has the pallet-weight equivalents and the legacy reference.
Class vs. item number. A freight class is a rating number, not an NMFC item number. The 13 tiers below are the classes density can return; the item number identifies the commodity description.

Browse by category
Browse the NMFC code directory by category
Category pages add the context a single row cannot: what changes the class inside the group, which forms are easy to confuse, and what to measure before you book.
Furniture & fixtures
Furniture is one of the hardest categories to classify because the same item can ship assembled, knocked down, or nested. Density, packaging, and whether the carrier can stack the handling unit usually decide the class.
Appliances & electronics
Appliances and electronics are bulky relative to their weight, so density usually lands in the middle of the scale. The packaging — foam, crates, and pallets — often matters more than the product itself.
Building materials
Building materials are usually dense and stable, which makes them easier to classify than furniture. The trap is shipping partial units, mixed loads, or material that is wet, wrapped, or bundled differently from the norm.
Metals & hardware
Metals and hardware are dense, so they usually sit at the low end of the class scale. The classification question is less about density and more about the exact form: plate, bar, extrusion, coil, or finished part.
Automotive
Automotive freight ranges from dense batteries to bulky bumpers and tires. New, used, and remanufactured parts can follow different items, and hazmat rules can override the density story entirely.
Food & beverage
Food and beverage freight is dense and often temperature-sensitive. Density is usually straightforward, but spoilage, alcohol rules, and temperature service change how the shipment must be handled.
Paper & packaging
Paper and packaging products are dense and compressible. The same product can ship as a skid, a bale, or a wrapped roll, and each form has a different density and handling profile.
Apparel & textiles
Apparel and textiles are light for their cube unless they are compressed or baled. Packaging — boxes, hanging garments, or rolls — drives the density more than the fabric itself.
Machinery & industrial
Machinery is dense and irregular. The handling unit is often a crate or a skid, and the class can depend on whether the item ships assembled, crated, or with accessories and fluids.
Medical & lab
Medical and lab freight is high-value and often temperature-sensitive. Density can be moderate, but liability, chain of custody, and temperature control usually drive the shipping decision.
Plastics & chemicals
Plastics and chemicals range from dense resin pellets to extremely light foam. Some products are regulated hazmat, and the packaging form can move the density by an order of magnitude.
FAQ
NMFC lookup FAQ
The methodology page documents the density scale, the data policy, and the correction process.
What is the NMFC, and what does this lookup show?
The National Motor Freight Classification is the North American classification system for less-than-truckload freight. It groups commodities into 18 classes and assigns item descriptions that carriers use with their tariffs. This lookup shows the classification basis, a typical packed density, and a class span derived from the 2025 density scale.
Is this NMFC lookup free?
Yes. The NMFC lookup tool is free, requires no account, and runs in your browser. It covers 40 common LTL commodities and does not publish unverified item numbers.
Why does this lookup not show NMFC item numbers?
NMFC item numbers are part of a proprietary publication, and the 2025 docket consolidated roughly 2,000 listings. Public lists are often stale. A wrong item number on a BOL is worse than no number, so this page shows the classification basis and a class span, then routes you to ClassIT+ or the carrier for the current item.
How is the class span calculated?
Each commodity has an estimated packed-density range. The endpoints of that range are mapped through the 13-tier density scale effective July 19, 2025. A 2–4 lb/ft³ estimate, for example, spans Class 250 at 2.0 and Class 175 at 4.0. The span is a planning range, not a guarantee that your shipment will hit every class in it.
What does density-rated mean?
Density-rated means the generic density scale usually sets the class when the shipment is measured as tendered. Item-specific means the NMFC item, not the density scale, controls the class. Mixed means some forms of the commodity follow density and others carry a fixed class or special provision. The item number decides which path applies.
Is this the same as the freight class chart?
No. The chart answers “my density is 7.97 lb/ft³, what class is that?” The lookup answers “how is a mattress, tire, or canned goods shipment classified, and what should I confirm?” Use the chart when you already have a density and the lookup when you are starting from the commodity.
Is there a freight class codes list here?
Yes. The 13-tier table is the list of classes that density can return, from Class 50 to Class 400. It is not a list of NMFC item numbers. A class is a rating number; the item number identifies the commodity description. Use the chart for the full list and this lookup for the commodity context.
Can I use the BOL description on the commodity pages?
The description templates are a starting point, not a classification. Put the confirmed NMFC item number, the commodity description, the handling-unit count, the gross weight, and the dimensions on the BOL. Keep photos of the pallet and packaging for a reclass dispute.
What if my commodity is not in the directory?
Use the freight class calculator to test your measured density against the 2025 scale, then confirm the item with ClassIT+ or the carrier. If you know a commodity that should be added, send the name and the reason to the correction address below.
How often is the reference reviewed?
The copy and ranges were reviewed on November 11, 2026 (reference 2026.11). The density scale is checked against the NMFTA effective date. Corrections that change a class span are reviewed before the page is updated.
