See Goldhofer Fahrzeugwerk GmbH Co. v. United States, 885 F.2d 858, 860 (Fed. Cir. 1989). Second, the importer bears the burden of checking for posted notices of actual assessment of duties and of timely protesting.See Omni U.S.A., Inc. v. United States 663 F. Supp. 1130, 1133 (Ct. Int'l Trade 1987), aff'd, 840 F.2d 912 (Fed. Cir. 1988); see also 21A Am.Jur.2dCustoms Duties and Import Regulations § 204 (1998) (citing Tropicana Prods., Inc. v. United States, 713 F. Supp. 415 (1989), aff'd, 909 F.2d 504 (Fed. Cir. 1990)). As this court pointed out in Juice Farms, when the importer bears the burden of examining the bulletin notices and protesting within the statutory time limits, then the importer is not entitled to equitable tolling if its own lack of diligence caused the untimely filing.

BALDWIN, Senior Circuit Judge. Tropicana Products, Inc. ("Tropicana") appeals the decision and judgment of the United States Court of International Trade ("CIT"), Tropicana Prods., Inc. v. United States, 713 F. Supp. 415 (CIT 1989), severing and dismissing Tropicana's protest number 1801-7-000027, covering entry numbers 81-103533-2 and 81-103789-3, from civil action number 87-10-00984, for lack of jurisdiction under 28 U.S.C. § 1581(a) (1988) because Tropicana failed to protest within the statutory 90-day period. We affirm.
