39 CFR § 3055.3 - Reporting exceptions.

(a) The Postal Service may petition the Commission to request that a product, or component of a product, be excluded from reporting, provided the Postal Service demonstrates that:

(1) The cost of implementing a measurement system would be prohibitive in relation to the revenue generated by the product, or component of a product;

(2) The product, or component of a product, defies meaningful measurement; or

(3) The product, or component of a product, is in the form of a negotiated service agreement with substantially all components of the agreement included in the measurement of other products.

(b) The Postal Service shall identify each product or component of a product granted an exception in each report required under subparts A or B of this part, and certify that the rationale for originally granting the exception remains valid.
