On March 17, 1978 the "Pennsylvania Agricultural Liming Materials Act" was signed into law. On March 4, 1994 the latest provisions of the "Agricultural Liming Materials Rules and Regulations" issued under said Act became effective.
Agricultural Liming Material is any product whose calcium and magnesium compounds are capable of neutralizing soil acidity. Liming materials are regulated through the licensing of PA manufacturing facilities and all guarantors of liming products. There is no product registration in Pennsylvania but we may require an applicant or licensee to provide labels for products to be distributed in the state.
Multi-purpose products intended to supply plant nutrients, soil/plant amendments and/or liming materials must be labeled, licensed and registered (as required) under each respective law prior to being offered for sale, sold or distributed in Pennsylvania. Samples are collected and analyzed to ensure labeling guarantees and otherwise meet requirements of compliance with the provisions of this Act.
A license is required for both the manufacturing and guarantor before an agricultural liming material can be manufactured or distributed in Pennsylvania. The annual licensing fee is twenty-five dollars ($25). The fee is due July 1 of each year or prior to the manufacturing or distribution of liming materials.
There is no product registration in Pennsylvania but we may require an applicant or licensee to provide labels for products to be distributed in the state.
In order to apply for a lime license, please complete form API-222 (Agricultural Liming Materials License Application). Please read instructions completely and print or type legibly. Instructions are included with the form.

Inspection Fee and Tonnage Reports:
The SEMI-ANNUAL inspection fee is three cents ($0.03) per ton, due on January 31 and July 31 of each year. A minimum fee of twelve dollars and fifty cents ($12.50) is required. If less than one ton was sold or distributed, report one ton on the report. If no sales (zero sales) are reported, do not pay minimum fee.
Lime tonnage is required to be reported SEMI-ANNUALLY on form API-204 (Agriculture Liming Materials Semi-Annual Tonnage Report) which is provided by our office to all licensees who manufacture and distribute agricultural liming materials in Pennsylvania.
The Inspection Fee and Agricultural Liming Materials Semiannual Tonnage Report (API-204) must be completed and postmarked by February 15 and August 15. After this date, a penalty of ten dollars ($10) or ten percent of the inspection fee, whichever is greater, will automatically be added to the inspection fee.

- Minimum Effective Neutralizing Value (ENV)
- The minimum percentage by weight passing through the US Standard sieves
(20 mesh, 60 mesh, and 100 mesh) as required by regulation.

Frequently Asked Questions
- Who is required to be licensed to sell agricultural liming materials in Pennsylvania?
Both the manufacturer and the person whose name appears on the label of the agricultural liming material must be licensed.
- Do individual products require registration?
No. Pennsylvania does not have product registration for agricultural liming materials.
- Is there required labeling for agricultural liming materials?
Yes. There is specific labeling information required for all agricultural liming materials. You can contact your nearest regional office or the Harrisburg Office for information or read the instructions for licensing under the Pennsylvania Agricultural Liming Materials Act.
- Who do I contact to determine the proper amount of a liming material needed?
Each County Cooperative Extension Office has soil test kits that can be purchased to determine the amount of liming material needed. The soil test results along with the required labeling for liming materials provide you with the information needed to determine application rate of a particular liming material. The soil test will also provide fertility information. The Extension Offices will also have general recommendations.
