(a) Notice of filing of petition. Upon the filing of a petition, a notice shall be published in the Federal Register setting forth that a petition has been filed by a domestic interested party, identifying the merchandise which is the subject of the petition, and its present and claimed appraised value or classification or rate of duty. The notice shall invite interested persons to make such written submissions as they desire within such time as is specified in the notice.

(b) Inspection of petition; inspection of documents and papers. The petition filed by a domestic interested party will be made available for inspection by interested parties in accordance with the provisions of 5 U.S.C. 552(a). However, neither a petitioner nor other interested parties will in any case be permitted to inspect documents or papers of the importer of record which are exempted from disclosure by 5 U.S.C. 552(b)(4). Identifying data is not to be deleted from petitions filed by American manufacturers, producers, and wholesalers pursuant to section 516, Tariff Act of 1930, as amended (19 U.S.C. 1516).

(a) Incorrect appraised value, classification, or rate of duty. If the appraised value of, classification of, or rate of duty upon imported merchandise of the character which is the subject of a petition is found to be incorrect, the Commissioner of Customs shall so inform the petitioner, and shall cause the proper value, classification, or rate of duty to be published in the Federal Register and the weekly Customs Bulletin. Such merchandise entered for consumption or withdrawn from warehouse for consumption after 30 days after the date of publication of such notice to the petitioner in the Customs Bulletin shall be appraised, classified, or assessed as to rate of duty in accordance with the published decision.

(b) Correct appraised value, classification, or rate of duty. If the appraised value of, classification of, or rate of duty upon the imported merchandise which is the subject of the petition is found to be correct, the Commissioner of Customs shall so notify the petitioner, but the decision shall not be published.

If the petitioner is dissatisfied with the decision of the Commissioner that the appraised value, classification, or rate of duty is correct for the merchandise which was the subject of the petition, in accordance with section 516, Tariff Act of 1930, as amended (19 U.S.C. 1516) he may file with the Commissioner of Customs not later than 30 days after the date of the decision a notice that he desires to contest the appraised value of, classification of, or rate of duty assessed upon the imported merchandise. Such notice shall designate the port or ports at which such merchandise is being imported into the United States, and at which the petitioner desires to protest.

Upon receipt of a properly filed petitioner's notice that he desires to contest the decision as to the appraised value of, classification of, or rate of duty assessed upon the imported merchandise, the Commissioner of Customs shall cause to be published in the Federal Register and the weekly Customs Bulletin a notice of his decision as to the proper appraised value of, classification of, or rate of duty assessed upon the imported merchandise, and of petitioner's desire to contest the decision.

(a) Information as to character and description of merchandise. All information secured by the director of the port designated by the petitioner in his notice of desire to contest as to the character and description of merchandise of the kind covered by the petition and entered after publication by the Commissioner of Customs of his decision as to the proper appraised value, classification and rate of duty, and samples of such merchandise, shall be made available to the petitioner upon application by him to the port director.

(b) Notice of liquidation. Notice of liquidation of the first of the entries to be liquidated which would enable the petitioner to present the issue desired shall be given to the petitioner by the director of the designated port as required by section 516. Tariff Act of 1930, as amended (19 U.S.C. 1516).

(c) Further notice when issue not presented. If, upon examination of the information and inspection of any sample supplied by the port director, the petitioner believes and the port director agrees that the merchandise or the facts surrounding this importation are not sufficient to raise the issue involved in the petition, the port director shall then give the petitioner notice of the first liquidation thereafter which will permit the framing of the issue covered by the petition. The port director shall, under the same conditions, continue to give notice for so long as he is of the opinion that the petitioner affirmatively intends to contest. When the port director concludes that the petitioner does not intend to contest the decision of the Commissioner of Customs, he shall refer the matter to the Commissioner of Customs for his decision before issuing any further notice of liquidation.
