Lumber yards, block and concrete suppliers, and building material distributors sit between manufacturers and contractors. You sell products that end up inside buildings, deliver them to busy job sites, run forklifts and yards all day, and extend credit to contractors who are waiting to get paid themselves.

This page explains, as education, the insurance and risk issues that matter to owners of construction material supply businesses in North Central and Northeast Florida.

What material suppliers deal with day to day

  • Product claims. A product you sold fails or is blamed for a defect in a building, and you’re named along with the manufacturer and the contractor.
  • Deliveries. Trucks, boom trucks and drivers unloading at job sites, sometimes onto roofs or upper floors.
  • Forklifts and yards. Forklift incidents, falling stacks and customers walking through the yard.
  • Inventory. Large and changing stock values, theft and storm damage to yard stock.
  • Getting paid. Contractor customers who don’t pay, and lien rights that depend on deadlines.
  • Installed sales. If your company installs what it sells, that work is construction, with its own insurance and workers’ comp rules.

Typical claims for material suppliers

Without quoting statistics, suppliers see auto claims from delivery trucks, injuries during unloading at job sites, forklift and yard injuries, and product liability claims, often as one of several defendants in a construction defect case. Property losses from fire, wind and theft of inventory are also common.

Customer contracts and certificates

GCs and developers increasingly ask suppliers for certificates and contract terms that look like a subcontractor’s, especially when you deliver onto the site. Common requests include minimum general liability and auto limits, additional insured status, a waiver of subrogation and primary and noncontributory wording. Read purchase orders and credit applications for indemnity language before you sign. A certificate is for information only. It doesn’t change or add coverage.

Send us the insurance pages of a contract if you’re not sure what it asks for. Certificate requests can go through our certificate request form.

Workers’ comp for your team

Most material suppliers are not construction businesses under Florida’s workers’ comp law, so the general rule applies: coverage is required once you have four or more employees, full- or part-time, including corporate officers or LLC members who haven’t filed an exemption. Many owners buy it sooner, because an uninsured injury can still turn into a lawsuit. If some of your people do construction work, such as installing what you sell, Florida can apply the one-employee construction rule to your whole business, so tell us about it.

Comp premium is an estimate based on payroll by job type, or class code. After the policy ends, the insurance company audits the real payroll. Florida’s audit rules require auditors to look at payments to employees, subcontractors and independent contractors, so keep a certificate of insurance on file for anyone you pay who isn’t on your payroll.

Report injuries right away. Florida requires the employer to report an injury to its carrier within 7 days after learning of it. More on our workers’ compensation page.

Your experience mod

Once your workers’ comp premium is large enough, NCCI calculates an experience mod for your business from about three years of payroll and claims, leaving out the most recent year. 1.00 is average. Some GCs and large customers ask for it when choosing vendors. Prompt injury reporting, light duty, correct class codes and checking the worksheet each year all help keep it accurate.

Trucks, forklifts and deliveries

Delivery trucks need commercial auto coverage with every driver listed and their records checked. If you use boom trucks or cranes to place materials, ask us how that work is covered, because lifting onto a structure carries more risk than dropping at the curb. OSHA requires forklift operators to be trained and evaluated, with an evaluation at least once every three years.

Lien rights and getting paid

Florida’s construction lien law requires suppliers who aren’t in a direct contract with the owner to serve a notice to owner before, or within 45 days after, first furnishing materials to preserve lien rights. Missing the deadline can cost you the right to a lien. This is a legal issue rather than an insurance one, so talk with your attorney about your process.

Practical risk management steps

  • Train and evaluate forklift operators and keep records
  • Separate customer walkways from forklift traffic in the yard
  • Use a delivery checklist: confirm the drop location, ground conditions and overhead lines
  • Keep manufacturer documentation and product data for what you sell
  • Report your inventory values accurately, especially before storm season
  • Track notice to owner deadlines for every job you supply

Questions to ask before you renew

  • Does my general liability cover products I sell and products I install?
  • Are my inventory limits right for my peak season?
  • Are delivery trucks, drivers and boom trucks listed correctly?
  • Do I need higher limits for the GCs I deliver to?
  • Are my class codes right for drivers, yard staff and any installers?
  • What is my experience mod, if I have one?

Frequently asked questions

Can I be sued for a product I didn’t make?

Yes. Suppliers are often named along with manufacturers and contractors. Products and completed operations coverage is part of most general liability policies.

Do I need workers’ comp with fewer than four employees?

Not under Florida’s general rule, but construction work like installing what you sell can trigger the one-employee construction rule.

How often do forklift operators need evaluation?

OSHA requires an evaluation of each operator at least once every three years, and more training after an incident or a change in conditions.

What is a notice to owner?

It’s a notice suppliers who don’t contract directly with the owner serve to preserve lien rights. Florida sets a 45-day deadline from first furnishing materials.

Why does a GC want me as a supplier to provide a certificate?

When you deliver onto the site, you bring risk onto the project. GCs ask for proof that you carry insurance to back it up.

Is inventory covered during a hurricane?

Usually under commercial property, subject to the windstorm deductible. Flood is usually excluded and needs separate coverage.
