II. Uniformity of Laws and Regulations

A. National Conference Goal

The goal of the National Conference on Weights and Measures (NCWM) with respect to these Uniform Laws and 

Regulations is to achieve their acceptance in all states and local jurisdictions that have authority over such matters. 

The Conference stands ready to assist any jurisdiction in any way possible in securing adoption.

B. Status of Promulgation

The following pages list, by state, information regarding the adoption of the Uniform Laws and Regulations. The 

tabulated data indicates if the state has adopted the Uniform Law or Regulation by reference, including subsequent 

amendments (thereby operating under the most recent version of the recommended regulation in this handbook), or if 

the state has used some version of the NCWM recommended law or regulation as guidance in developing a similar 

law or regulation.

The information is verified with each state annually; the entries represent the status of the state adoption at the time 

of the survey.

Unless a state adopts the recommended regulations and subsequent amendments and revisions, there may be variation 

in the actual degree of adoption. Adoption, implementation, and clarification may be determined by comparing a state 

law with the Uniform Law, section-by-section, or by contacting the state.

(Amended 1997 and 1998)

C. Summary of State Laws and Regulations in Weights and Measures (as of November 1, 2021)

This is an overview of the status of adoption of NCWM standards by the states. In earlier editions of Handbook 130, 

state laws and regulations were compared to the NCWM standard from the prior year. This did not indicate whether 

the standard as printed in the current edition had been adopted by any given state. The table lists those states that 

adopt NCWM-recommended updates automatically (“YES”); see Sections 4 through 9 and paragraph 11.(m) of the 

Uniform Weights and Measures Law. This means the state’s regulations are current with those printed in this edition 

of the handbook. If a state has adopted an NCWM recommendation in whole or in part from a particular year, but 

updates are not incorporated automatically, a lower case “yes” is shown. For additional information on the status of 

adoption, please contact the appropriate state officials.
