G. Uniform E-commerce Regulation

1. Background

The Uniform E-commerce Regulation was adopted during the 108th Annual Meeting of the National Conference on 

Weights and Measures (NCWM) in 2023. 

NCWM adopted a model e-commerce regulation to assist those states authorized to adopt such a regulation under 

provisions of their weights and measures laws. The customer benefit of having clear and consistent price, quantity 

and identity information during an e-commerce transaction should be greater confidence that a product purchased is 

actually the product they intended to purchase. The manufacturer benefit of this e-commerce regulation is clear 

expectations of what information is required to be provided on e-commerce sites offering products for sale and 

product information accompanying product delivery. 

Nothing contained in this regulation should be construed to supersede any labeling requirement specified in federal 

law.

2. Status of Promulgation 

This regulation shall become effective and subject to enforcement on January 1, 2025.

Preamble

The purpose of this regulation is to provide accurate and adequate identity and net quantity information for products 

sold via e-commerce to help facilitate purchaser confidence in e-commerce purchases. This regulation establishes 

requirements for e-commerce sites offering products for purchase, product labeling for products sold via ecommerce and for receipts which detail the identity, quantity, and price the consumer paid upon product delivery. 

This regulation applies to product identity, net quantity, responsible parties, and price information and is not 

intended to apply to other product labeling or quality requirements.

Section 1. Application

This regulation shall apply to products and transactions which occur when purchasers are not present to purchase a 

consumer or non-consumer product in person.

without being physically present to inspect and select individual products and commodities in-person. This 

regulation also applies to any product information that shall accompany the transaction(s) including but not limited 

to labeling and receipts.

This regulation shall not apply to:

6.4. Measurement Systems. – The International System of Units (SI), known as the metric system and the U.S. 

customary system of weights and measures are recognized as proper systems to be used in the declaration of 

quantity for e-commerce products. Units of both systems may be combined in a dual declaration of quantity. 

Numerical count is permitted for products when the product statement of identity and numerical count are fully 

informative of the product’s contents.

G. Uniform E-commerce Regulation

223

particular E-commerce product shall be expressed in terms of liquid measure if the commodity is liquid, in terms of 

dry measure if the commodity is dry, in terms of weight if the commodity is solid, semisolid, viscous, or a mixture 

of solid and liquid, or in terms of numerical count. However, if there exists a firmly established general consumer 

usage and trade custom with respect to the terms used in expressing a declaration of quantity of a particular 

commodity, such declaration of quantity may be expressed in its traditional terms if such traditional declaration 

gives accurate and adequate information as to the quantity of the commodity.

6.7. SI Units: Mass and Measure. – A declaration of quantity for an e-commerce product or package shall be

limited to a printed directory, electronic database, or website.

the label may state the principal place of business in lieu of the actual place where the commodity was manufactured 

or packed or is to be distributed, unless such statement would be misleading. Where the commodity is not
