42 U.S.C. § 4907 — Labeling

(a) Regulations. By regulation, the Administrator^* must designate any product^* or class of products that either emits noise capable of harming public health or welfare, or is sold wholly or partly because it reduces noise.

(b) Notice method, form, and measurements. For each designated product or class, the Administrator must require by regulation that the prospective user be told the product’s noise level or, as applicable, how effective it is at reducing noise. The regulations must specify:

(1) whether, when the product is sold to the ultimate purchaser^*, the notice must be attached to the product, attached to the outside of its container, attached to both, or given to the prospective user in another way;

(2) the notice’s form; and

(3) the measurement methods and units to use.

Section 4905(c)(2) applies when a regulation is prescribed under this section.

(c) State^* regulation of product labeling. This section does not stop a State or its political subdivision from regulating product labeling or product information in a way that does not conflict with the Administrator’s regulations under this section.
