Risk-based selection for customs verification emphasizes risk evaluation; changes narrow verification scope and clarify self-assessment. Amendments to section 17 expand references to include entries under section 46 or 50 together with self-assessment, require that case selection for verification be primarily based on risk evaluation through appropriate selection criteria, substitute wording in sub-section (3) to refer to 'the purposes of verification,' omit the clause in sub-section (5) addressing valuation, classification and exemptions, and omit sub-section (6).
