Time for filing. A protest may be amended at any time prior to the expiration of the period within which the protest may be filed under § 174.12(e). The amendment may assert additional claims pertaining to the administrative decision that is the subject of the protest, or may challenge an additional administrative decision relating to the same category of merchandise that is the subject of the protest. For the presentation of additional grounds or arguments in support of a valid protest after the applicable protest period set forth in § 174.12(e) has expired, see § 174.28.

Form and number of copies of amendment. If the protest was not filed electronically, an amendment to the protest must be filed in quadruplicate on CBP Form 19 or on a form of the same size, clearly labeled “Amendment to Protest” at the top of the form. Schedules or other attachments (other than samples or similar exhibits) must also be filed in quadruplicate. A protest that was transmitted to CBP electronically may be amended only through an electronic data interchange system authorized by CBP for that purpose. Electronic submissions are not required to be filed in quadruplicate.
