Advance ruling scheme provides binding pre-import customs decisions and a limited appeal mechanism for applicants. A statutory scheme provides for advance rulings under the Customs Act: applicants submit prescribed applications on enumerated issues (classification, notification applicability, valuation, tax or duty notifications, origin, or other notified matters), may be represented, and pay a fee. The Authority examines records, allows hearings on request, pronounces rulings in writing within a statutory period, and may refuse applications that are pending or already decided. Rulings are binding on the applicant and relevant customs authorities unless law or facts change, and may be declared void for fraud; appeals lie to a designated Appellate Authority.
