39 CFR §3055.3

1. (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. (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. (2)The product, or component of a product, defies meaningful measurement; or
   3. (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.
2. (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.
