The South African Revenue Service has since 2009 introduced “reference pricing” as a tool to detect undervaluation of customs values of imported clothing and textiles. The term “reference pricing” is not defined in the Customs and Excise Act No.91 of 1964 which is the legislation that governs the importation of goods into the Republic of South Africa. The mandate of the South African Revenue Service, amongst others, is to facilitate legitimate trade. By applying the reference pricing guidelines the South African Revenue Service will target all importers who declare customs values which are less than the reference price for a targeted tariff heading associated with an item of clothing or textile. The Customs and Excise Act No.91 of 1964 is clear in that the transaction value which is the price paid or payable for the imported goods shall be the value used for customs duty purposes. The Customs and Excise Act No.91 of 1964 also requires that the interpretation of the sections 65, 66 and 67 of the said Act shall be subject to the Agreement on Implementation of Article VII of the General Agreement on Tariffs and Trade 1994 (Valuation Agreement). Part I of the Valuation Agreement deals with the rules for customs valuation. Article 17 of part 1 allows for customs administrations to satisfy themselves as to the truth or accuracy of any statement, document or declaration presented for customs valuation purposes. The Technical Committee on Customs Valuation of the World Trade Organisation decided the following in so far as Article 17 of the aforesaid agreement is concerned: “1. When a declaration has been presented and where the customs administration has reason to doubt the truth or accuracy of the particulars or of documents produced in support of this declaration, the customs administration may ask the importer to provide further explanation, including documents or other evidence, that the declared value represents the total amount actually paid or payable for the imported goods, ....” It would appear that the South African Revenue Service is using reference prices as a tool to support its reason for doubting the truth or accuracy of the declared customs values. The indiscriminate use of reference pricing, it is submitted, affects legitimate trade adversely. This treatise provides an understanding of how the customs value should be determined in terms of the Customs and Excise Act No.91 of 1964 and the Valuation Agreement. It then provides a background to reference pricing and how reference pricing will be used to detect undervalued imports of clothing and textiles, the advantages and disadvantages of using reference pricing and a comparative analysis of the approach adopted by the Mexican Tax Administration Service in so far as the use of reference pricing is concerned. It was established that the reference price cannot replace the customs value of an imported clothing item as the customs value is based on the price actually paid or payable for it and not on some arbitrary or fictitious value. The reference price can only be used as a tool to identify importers that are possibly undervaluing the customs values. The disadvantages far outweigh the advantages of using reference pricing. The treatise further provides a background to the use of a valuation database as a risk assessment tool and compares this to the use of reference pricing. The use of reference pricing and its impact on trade facilitation is then discussed as well as whether the use of reference pricing is consistent with the risk management principles as discussed in the World Customs Organisation Risk Management Guide. It was established that the South African Revenue Service has not disclosed the basis of arriving at the reference price per tariff heading that it targets and the use of reference pricing is not sanctioned by any international guideline or agreement. It was also established that the use of reference pricing targets compliant importers unnecessarily and this practice goes against the principles of trade facilitation. The use of reference pricing can be used as a tool to detect undervalued imports of clothing but should not be used as a basis to stop every consignment of clothing simply because the customs value declared is less than the reference price. It should not be used as a stand-alone tool but rather enhanced further with the recommendations provided. In the final analysis, recommendations are provided which seek to enhance the reference pricing mechanism and to further identify and exclude compliant importers and limit the use of reference pricing to target non-compliant importers who undervalue the customs value of imported clothing and textile items.
