((a)) ** Types of requirements** The Commission may promulgate consumer product safety standards in accordance with the provisions of . A consumer product safety standard shall consist of one or more of any of the following types of requirements:
((1)) Requirements expressed in terms of performance requirements.
((2)) Requirements that a consumer product be marked with or accompanied by clear and adequate warnings or instructions, or requirements respecting the form of warnings or instructions.
((b)) ** Reliance of Commission upon voluntary standards**
((1)) The Commission shall rely upon voluntary consumer product safety standards rather than promulgate a consumer product safety standard prescribing requirements described in subsection (a) whenever compliance with such voluntary standards would eliminate or adequately reduce the risk of injury addressed and it is likely that there will be substantial compliance with such voluntary standards.
((2)) The Commission shall devise procedures to monitor compliance with any voluntary standards—
((A)) upon which the Commission has relied under paragraph (1);
((B)) which were developed with the participation of the Commission; or
((C)) whose development the Commission has monitored.
((c)) ** Contribution of Commission to development cost** If any person participates with the Commission in the development of a consumer product safety standard, the Commission may agree to contribute to the person’s cost with respect to such participation, in any case in which the Commission determines that such contribution is likely to result in a more satisfactory standard than would be developed without such contribution, and that the person is financially responsible. Regulations of the Commission shall set forth the items of cost in which it may participate, and shall exclude any contribution to the acquisition of land or buildings. Payments under agreements entered into under this subsection may be made without regard to section 3324(a) and (b) of title 31.
