NAICS 327420 · United States · 2022 edition
This industry comprises establishments primarily engaged in manufacturing gypsum products, such as wallboard, plaster, plasterboard, molding, ornamental moldings, statuary, and architectural plaster work. Gypsum product manufacturing establishments may mine, quarry, or purchase gypsum.
Start the review with product liability.
For Gypsum Product Manufacturing, the saved research highlights product liability, workers' compensation, environmental/pollution liability. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- Does the operation mine or quarry its own gypsum, or purchase raw material from outside suppliers?
- Is any synthetic gypsum used, such as material from industrial byproducts?
- What finished products are manufactured, and what downstream markets are served — residential, commercial, industrial?
- What dust control, ventilation, and employee respiratory protection programs are in place?
- Any prior product liability claims or construction defect litigation involving manufactured products?
- What is the distribution footprint — local, regional, or national — and how is product shipped?
- For Gypsum Product Manufacturing, what should the underwriter know about on-site mining or quarrying operations in addition to manufacturing?
- For Gypsum Product Manufacturing, what should the underwriter know about use of synthetic gypsum from industrial byproducts (e.g., flue gas desulfurization) with uncertain chemical profiles?

Gypsum product manufacturers receive raw gypsum — either mined on-site or purchased — and process it through calcination (heating to remove water), mixing with additives, and forming into finished products such as wallboard panels, plaster, plasterboard, and architectural moldings. Operations typically involve heavy equipment, kiln or oven systems, conveyor lines, and dust-generating processes. Finished product is typically sold to building material distributors, contractors, or big-box retailers.
