5 Things Mills Require Before You Haul

June 6, 2026 · Jeremiah O'Donovan

New contract, new mill — and before your first load, their risk department wants paperwork. Having it ready is the difference between hauling Monday and sitting on the landing. Here’s what they almost always ask for.

1. A certificate of insurance (COI)

The COI is the one-page proof of your coverage. Mills want it on file before you start, and they want it current — an expired COI can stop you at the gate.

2. Auto liability limits that meet the contract

Most mills require a $1,000,000 combined single limit on commercial auto liability. Bigger operations and some landowners ask for more, often backed by excess liability.

3. General liability

Separate from your trucks, loggers general liability covers third-party injury and property damage on the job — and it’s frequently a contract requirement.

4. Additional insured status

Mills and landowners usually want to be named as an additional insured on your policy, extending your coverage to protect them for your operations. Your agent can issue this with the COI.

5. Proof of securement and motor-carrier compliance

Beyond insurance, expect questions about load securement, driver qualifications, and authority. Operating to standard keeps both your contract and your coverage intact.

The fastest way to keep all of this in order is to work with an agent who knows the program. Find a Longleaf® agent and we’ll make sure your paperwork is ready before the mill asks.
