19 CFR §173.5

An error in the liquidation of an entry covering household or personal effects may be corrected by the port director even though a timely protest was not filed if entry was made before December 18, 2004 and an application for refund is filed with the port director within 1 year after the date of the entry and no waiver of compliance with applicable regulations is involved other than a waiver which the port director has authority to grant. Where the port director has no authority to grant the waiver, the application will be referred to the Commissioner of CBP.
