An upward revision in customs charges and new levies for importing goods will raise the landed cost of various products in the country, according to sources in importing firms and shipping agencies. The customs department has started charging an additional 2 per cent on the CIF (cost, insurance and freight) value of imported products for non-submission of original legalised documents. The 2 per cent additional charge is reimbursable once the importer produces the original legalised documents of certificates of origin and commercial invoice within 90 days. These documents have to be attested by the embassy of Oman in the exporting country. (Times of Oman)
