Freight Contract Terms Guide: What Every Shipper Should Understand

Base Rates and Discount Structure

The base rate clause is the foundation of any freight contract. For LTL, it is expressed as a discount percentage off a published tariff (e.g., "68% off CZAR 2000 effective January 1, 2026"). For FTL and specialized modes, it is a flat rate per mile, per load, or per pallet by lane. Understanding how base rates are structured determines whether you can benchmark your rates and detect drift over time.

Key provisions to negotiate:

• Tariff lock: Specify which tariff edition the discount applies to. Carriers periodically introduce new tariffs with higher base rates. A "68% off CZAR 2000" discount applied to a new CZAR tariff with higher base rates may result in a higher net rate even with the same discount percentage.
• Lane-specific rates vs. blanket discount: Blanket discounts apply the same percentage to all lanes, which benefits carriers on high-density lanes and disadvantages shippers on low-density or difficult-to-serve lanes. Lane-specific rates are more transparent and often more favorable for shippers with concentrated volumes.
• Minimum charge: The minimum charge per shipment is often where carriers recapture margin on small freight. Negotiate the minimum explicitly and confirm it is included in your all-in rate model.

Fuel Surcharge Provisions

The fuel surcharge is the most volatile component of freight cost and the one most shippers under-negotiate. Standard contracts index the fuel surcharge to the U.S. Department of Energy (DOE) weekly retail diesel price, applying a carrier-defined multiplier table that specifies the surcharge percentage at each DOE price tier.

Provisions that matter:

• Index reference date: Fuel surcharges update weekly or monthly. A contract that updates weekly introduces more cost volatility than one that updates monthly. Negotiate monthly updates for budget predictability.
• Fuel surcharge cap: A cap limits the maximum fuel surcharge regardless of DOE index movement. For a shipper with $5M in annual freight spend and fuel at 25% of cost, a cap that prevents fuel from exceeding 30% of base rate is worth approximately $250K in downside protection during a fuel price spike.
• Alternative, all-inclusive pricing: Carriers offering per-pallet all-inclusive pricing eliminate fuel surcharge exposure entirely. This is the structural alternative to negotiating fuel caps on traditional LTL contracts. See per-pallet pricing for detail on how this model works.

Accessorial Schedule

The accessorial schedule is a list of every additional charge the carrier may apply beyond base rate and fuel. Standard accessorials include: residential delivery, liftgate service, inside delivery, limited access, detention/layover, redelivery, address correction, and notification/appointment fees. The schedule is often an appendix to the contract that receives minimal attention during negotiation, and it frequently causes the most post-signature disputes.

What to do with the accessorial schedule:

• Map each accessorial to your actual freight profile. If you never ship to residential addresses, the residential surcharge is irrelevant. If 30% of your deliveries require liftgate, negotiate a liftgate rate that reflects your volume.
• Negotiate waivers for accessorials that are predictable and frequent. A carrier who knows you will generate 200 liftgate shipments per month has incentive to build liftgate into a flat all-in rate rather than charging per event.
• Include a provision that prevents carriers from adding new accessorial categories mid-contract without 60-day written notice. This prevents carriers from inventing new surcharges (fuel recovery fees, peak surcharges) between renewals.

Liability Caps and Claim Filing Windows

Freight liability provisions determine how much you can recover when cargo is lost or damaged, and the procedural requirements for making a claim. Two clauses require specific attention:

Liability cap per pound: Standard LTL liability is set by freight class, typically $0.10 to $2.00 per pound depending on class. High-value freight (electronics, pharmaceuticals, specialty goods) requires negotiated higher per-pound liability or declared value coverage. Verify that the liability cap is adequate for your highest-value freight before signing.

Claim filing window: The time limit to file a cargo claim is typically 9 to 12 months from delivery date. Missing this window, regardless of fault, forfeits your recovery rights. Build a claim tracking process into your operations team workflow. Many shippers discover claims past the filing window because the damage was not identified until the freight reached the customer.

Also verify the carrier's claim payment timeline. The contract should specify payment within 30 to 60 days of claim approval. Open-ended payment timelines allow carriers to defer settlements indefinitely.

Rate Escalators and Volume Commitments

Rate escalator clauses specify how contract rates change over the term. The most common structures:

• Fixed annual increase: Rates increase by a fixed percentage (e.g., 2.5%) at each anniversary. Predictable and negotiable.
• CPI-linked increase: Rates increase by the Consumer Price Index change. Fair in principle, but CPI may not reflect carrier cost structure accurately.
• Carrier-defined GRI: The carrier applies its published General Rate Increase at renewal. GRIs historically run 5 to 7% annually. This clause gives the carrier unilateral pricing power and should be avoided or capped.

Volume commitments should be expressed as a percentage of lane volume (e.g., "80% of shipper's LTL volume on the Chicago-Atlanta corridor") rather than an absolute shipment count. An absolute count creates breach risk during demand downturns. A percentage commitment flexes with your business volume.

Termination clauses should provide 60 to 90 day written notice on either side without cause, plus clear language on rate protection during the notice period. A termination clause that allows the carrier to raise rates immediately upon notice effectively penalizes the shipper for exercising termination rights.
