Shipping furniture via LTL freight? Getting the freight class wrong costs you money — lots of it. Carriers re-classify incorrectly classed furniture shipments and charge re-weigh fees of $50-500 per pallet, plus the rate difference.

The good news: furniture freight class follows a simple density formula. Most furniture falls into Class 70, 85, or 100. This guide shows you exactly how to calculate the correct class, avoid re-classification, and save hundreds per shipment.

Quick Answer: Common Furniture Freight Classes

Most Furniture Ships as:

Class 70: Solid wood furniture (dining tables, dressers, hardwood items) — 15-22.5 PCF density
Class 85: Mixed wood/particle board furniture — 12-13.5 PCF density
Class 100: Upholstered furniture, lightweight items — 9-10.5 PCF density

But you can't just guess. Carriers weigh and measure everything. If your declared class doesn't match the actual density, you'll get hit with re-class fees. Here's how to calculate it correctly.

The Formula: How to Calculate Freight Class for Furniture

Freight class for furniture is determined by PCF density (pounds per cubic foot). Here's the exact formula:

Density (PCF) = Weight (lbs) ÷ Volume (cubic feet)

Volume = (Length × Width × Height in inches) ÷ 1,728

Step-by-Step Example: Dining Table

Let's calculate freight class for a palletized dining table:

Dimensions (palletized): 48" L × 40" W × 50" H (includes pallet height)
Weight (including pallet): 400 lbs total (350 lbs table + 50 lbs pallet)
Calculate Volume:
Volume = (48 × 40 × 50) ÷ 1,728 = 96,000 ÷ 1,728 = 55.6 cubic feet
Calculate PCF Density:
PCF = 400 lbs ÷ 55.6 cu ft = 7.2 PCF
Map to Freight Class:
7.2 PCF = Class 100 (density range: 6-7 PCF maps to Class 125, 7-8 PCF maps to Class 110, but furniture NMFC codes typically put 7-9 PCF at Class 100)

Critical: ALWAYS Include Pallet Weight & Dimensions

The #1 reason furniture gets re-classed: shippers measure and weigh the furniture alone, forgetting the pallet. NMFC rules require the complete shipping unit. A 48×40 pallet weighs 30-70 lbs and adds 4-6 inches to height. Forgetting it drops your density and triggers expensive re-classification.

Freight Class Density Chart for Furniture

Here's how PCF density maps to freight class for typical furniture items:

Freight Class	PCF Density Range	Common Furniture Examples
Class 70	15 - 22.5 PCF	Solid hardwood tables, dressers, cabinets, metal furniture
Class 85	12 - 13.5 PCF	Mixed materials, particle board, engineered wood furniture
Class 92.5	10.5 - 12 PCF	Lightly built furniture, some upholstered items
Class 100	9 - 10.5 PCF	Upholstered chairs/sofas, lightweight furniture, heavily packaged items
Class 125	6 - 8 PCF	Small household furniture (NOI), lamps, very lightweight items

Real Cost Impact: Class 70 vs Class 100

Getting the freight class wrong isn't a small mistake. Here's the actual cost difference for a typical 500 lb furniture shipment going 800 miles:

Same shipment, different classes:

Class 70: $285 (Correct for solid wood)

Class 85: $340 (+$55 vs Class 70)

Class 100: $425 (+$140 vs Class 70)

Class 100 + Re-class Fee: $625 (If initially declared as Class 70)

If you ship 50 furniture pallets per year and consistently under-classify by one class, you're paying an extra $7,000-$10,000 annually in carrier adjustments and re-class penalties.

5 Common Furniture Freight Class Mistakes

Not including pallet weight (30-70 lbs)
This drops your density calculation and causes re-classification. Always weigh the complete palletized unit.
Measuring furniture alone instead of palletized dimensions
Pallets add 4-6 inches to height. Use extreme dimensions of the entire shipping unit, including any overhang.
Rounding down instead of up
If your PCF calculates to 14.8, you're Class 85 (12-15 PCF range), not Class 70. Round conservatively.
Using "household furniture NOI" as a shortcut
The NMFC code for "household furniture NOI" (Not Otherwise Identified) defaults to Class 125. If your furniture has higher density, you're overpaying. Always calculate actual density.
Forgetting packaging materials
Bubble wrap, cardboard, corner protectors, stretch wrap — all add weight and dimensions. Include everything that ships with the furniture.

What If My Furniture Doesn't Fit the Standard Classes?

Some furniture shipments have special considerations:

Oversized items (over 12 linear feet): May trigger additional charges beyond freight class. Measure carefully and notify carriers in advance.
High-value furniture ($5,000+): Requires declared value and may affect liability calculations, but doesn't change freight class. Class is density-based only.
Non-stackable furniture: Doesn't change the freight class calculation, but may result in accessorial charges. Notify the carrier with "non-stackable" on the BOL.
Antique or fragile furniture: Consider "inside delivery" or "white glove" services, but calculate freight class normally based on density.

Pro Tips for Shipping Furniture LTL

Use certified scales: Bathroom scales aren't accurate enough for freight. Use a commercial scale or ask your carrier to weigh at pickup.
Document everything: Take photos of measurements, the scale reading, and the palletized shipment. If you dispute a re-class, you'll need proof.
Calculate before you pack: If you're borderline between classes, optimize your packaging to hit the higher-density (lower-cost) class.
Know your NMFC codes: Furniture falls under NMFC codes 80460-81750 depending on type. Knowing the specific code helps during carrier disputes.

Final Checklist: Shipping Furniture LTL

Before you complete the BOL:

✅ Measured palletized dimensions (L × W × H in inches)
✅ Weighed complete shipment including pallet
✅ Calculated PCF density: Weight ÷ ((L×W×H)÷1,728)
✅ Mapped density to correct freight class using chart
✅ Double-checked: rounded UP if borderline between classes
✅ Documented measurements with photos
✅ Declared class matches actual density

Bottom line: Furniture freight class is simple math. Measure accurately, include the pallet, calculate PCF density, and map to the correct class. Do this every time and you'll never get hit with a re-class fee again.

Frequently Asked Questions

What freight class is furniture typically?

Most furniture shipments are Class 70, 85, or 100 depending on density (PCF). Solid wood furniture (denser) is typically Class 70 (15-22.5 PCF). Upholstered furniture or particle board items are usually Class 85 (12-13.5 PCF) or Class 100 (9-10.5 PCF). The exact class depends on weight and dimensions after palletizing.

How do I calculate PCF for furniture?

Calculate PCF (pounds per cubic foot) using this formula: Weight (lbs) ÷ Volume (cubic feet). For volume: multiply Length × Width × Height in inches, then divide by 1,728. Example: A 400 lb furniture pallet measuring 48×40×50 inches = 400 ÷ ((48×40×50)÷1,728) = 400 ÷ 55.6 = 7.2 PCF, which maps to Class 100.

Why does my furniture keep getting re-classed?

Furniture re-classifications happen when carriers discover the actual density differs from what was declared on the BOL. Common causes: not including pallet weight (30-70 lbs), measuring furniture alone instead of palletized dimensions, using inside dimensions instead of extreme dimensions, or rounding down instead of up. Always measure and weigh the complete palletized shipment.

Should I include pallet weight when shipping furniture?

Yes, absolutely. NMFC rules require freight class calculations to include the complete shipping unit, which means furniture plus pallet plus all packaging. A standard 48×40 wood pallet weighs 30-70 lbs. Forgetting pallet weight reduces your calculated density, causing carriers to re-classify at a higher (more expensive) class and charge re-class fees of $50-500.

What's the difference between Class 70 and Class 100 furniture?

Class 70 furniture is denser (15-22.5 PCF) - typically solid wood items like dining tables, dressers, or hardwood cabinets. Class 100 furniture is less dense (9-10.5 PCF) - usually upholstered items, particle board furniture, or items with significant packaging. The cost difference is substantial: Class 100 can be 30-40% more expensive than Class 70 for the same weight.

Can furniture ever be Class 50?

Rarely. Class 50 requires density over 50 PCF, which would be extremely heavy, solid items like metal furniture or very dense hardwoods shipped with minimal packaging. Most wood furniture falls into Class 70-100. If a furniture shipment calculates to Class 50, double-check your math - it's likely an error in dimensions or you forgot to divide by 1,728 when calculating volume.
