Liming Material

In Pennsylvania, companies that make or sell limiting materials need to be licensed. 

Overview

Agricultural Liming Material helps make soil less acidic by adding calcium and magnesium. To make or sell agricultural liming material, you need a license for both the manufacturer and the person who guarantees the product. The license costs $25 each year and must be paid before starting to make or sell the product.

To get a license, fill out form API-222 and follow the instructions. You can apply and pay online with a credit card. You can also find a list of licensed facilities in Pennsylvania online. You don’t need to register each product, but all products must have labels and follow the rules before they can be sold or given out in Pennsylvania. Samples of these products are checked to make sure they follow the rules and match their labels.
