06- 096 C.M.R. ch. 870, § 6
Except as otherwise provided in section 4, mercury-added products that are components of larger products offered for sale in Maine must be labeled in accordance with the requirements of this rule. If the component is enclosed in the larger product such that the label on the component cannot be seen, then the product containing the component also must be labeled in accordance with the requirements of this rule and the label must identify the component in sufficient detail so that it may be readily located for removal. If the component is incorporated in the larger product such that the label on the component is fully visible, then labeling of the larger product is not required.
This section does not apply to a mercury-added product in which the only mercury-added component is one or more lamps. This section also does not apply to a mercury-added lamp that is a component of a larger product if the product is designed such that the lamp is not readily replaced by the product user and is not intended to be replaced by the user.
