Classification of palm oil imports: compositional criteria determine crude versus refined tariff treatment and assessment procedures. Classification distinguishes crude and RBD palm oil/palmolein by compositional criteria-carotenoid content and acid value for crude; refined specifications for RBD-with crude and RBD each assigned distinct tariff sub headings and nonconforming grades falling under a residuary category. For entries before the definition's effective date, Port Health Officer test reports indicating crude or RBD status should guide assessment; ambiguous reports require review of assessment practice and potential invocation of customs assessment provisions. Warehoused goods cleared after the effective date are assessed at rates applicable on the bill of entry filing date for home consumption.
