NAICS 322130 · United States · 2022 edition
This industry comprises establishments primarily engaged in manufacturing paperboard (e.g., can/drum stock, container board, corrugating medium, folding carton stock, linerboard, tube) from pulp. These establishments may manufacture or purchase pulp. In addition, the establishments may also convert the paperboard they make.
Start the review with equipment breakdown.
For Paperboard Mills, the saved research highlights equipment breakdown, property, 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 mill manufacture its own pulp on-site, or does it operate exclusively on purchased pulp?
- Are there recovery boilers or chemical pulping systems on-site?
- What is the replacement cost and age of the primary paper machines?
- What is the current status of environmental permits, wastewater discharge compliance, and any prior agency enforcement history?
- What fire suppression systems are installed, and when were they last inspected?
- What is the anticipated business interruption exposure if the primary paper machine is out of service for an extended period?
- For Paperboard Mills, what should the underwriter know about on-site recovery boiler or chemical pulping operations, which significantly increase both property severity and boiler explosion exposure?
- For Paperboard Mills, what should the underwriter know about prior pollution incidents, active regulatory enforcement actions, or unresolved environmental consent orders?

Paperboard mills manufacture paperboard grades — such as linerboard, corrugating medium, folding carton stock, and tube stock — from pulp that may be manufactured on-site or purchased externally. Operations typically involve large paper machines, wet-end chemistry, drying and calendering systems, and on-site utilities including high-pressure steam boilers and recovery boilers. Some mills also perform in-house converting of finished paperboard.
