Certain commercial entities, equipment, or materials may be identified in this document to describe an experimental 

procedure or concept adequately. Such identification is not intended to imply recommendation or endorsement by 

the National Institute of Standards and Technology (NIST), nor is it intended to imply that the entities, materials, or 

equipment are necessarily the best available for the purpose. 

This handbook promotes the primary use of the International System of Units (SI) by citing SI units before U.S. 

customary units where both units appear together, and by placing separate sections containing requirements for SI 

units before corresponding sections containing requirements for customary units. In some cases, however, trade 

practice is currently restricted to the use of U.S. customary units; therefore, some requirements in this handbook will 

continue to specify only U.S. customary units until the National Conference on Weights and Measures (NCWM) 

achieves a broad consensus on the permitted metric units.

Marijuana (also referred to as cannabis) remains a Schedule I substance under the Controlled Substances Act. As 

with all materials, the NIST Office of Weights and Measures (OWM) provides technical analysis and any relevant 

expertise to help ensure that the standards as developed through the NCWM process are technically sound. As such, 

NIST publishes the adopted model regulations for cannabis and cannabis-containing commodities by the NCWM in 

the NIST Handbook 130 as part of NIST’s statutory mission to promote uniformity in state laws, regulations, and 

testing procedures.1

Abstract

NIST Handbook 130 includes a compilation of model laws and regulations and related 

interpretations and guidelines designed to encourage uniformity in adoption and implementation 

of weights and measures laws and regulations. The model laws and regulations included in 

NIST Handbook 130 are adopted in various forms by many state, local, and some federal 

weights and measures authorities. Some authorities adopt the current versions as written; some 

use them as the basis of adoption, but from an earlier year; some use them as a guideline only; 

some elect to use their own laws or regulations; and some have no corresponding law or 

regulation in place. 

The National Institute of Standards and Technology (NIST) has a statutory responsibility to 

promote "cooperation with the states in securing uniformity in weights and measures laws and 

method of inspection” and publishes this and other NIST Handbooks in partial fulfillment of this 

responsibility. 

This 2024 edition includes amendments made through the Committee on Laws and Regulations 

of the NCWM with technical guidance from the Office of Weights and Measures (OWM) of the 

National Institute of Standards and Technology (NIST) and input from weights and measures 

officials and industry representatives. These amendments were adopted by the NCWM at its

108th Annual Meeting in July 2023. 

At the 1983 Annual Meeting, the NCWM voted to change the title of Handbook 130 from 

“Model State Laws and Regulations” was to be changed to “Uniform Laws and Regulations” to 

reflect that these Laws and Regulations are (a) intended to be standards rather than just 

guidelines, and (b) intended for adoption by political subdivisions other than states when deemed 

appropriate. In 1995 the title was changed to Uniform Laws and Regulations in the areas of legal 

metrology and motor fuel quality. In the 1997 Edition of Handbook 130 was changed from 

"Uniform Laws and Regulations the words “motor fuel quality" was changed to “engine fuel 

quality" to reflect changes made to the Uniform Engine Fuels, Petroleum Products, and 

Automotive Lubricants Law and Regulation. In 2018, the scope of the Fuels regulation was 

expanded to encompass the changing fuels in the marketplace, and the title to the Handbook was 

changed to how it appears today.
