Colgate-Palmolive imported tetranyl L1-905, a product used in making fabric softener and conditioner (StaSoft), from Spain. Tetranyl is a quaternary ammonium compound imported in paste form mixed with isopropanol to facilitate handling and transport. It combines triethanolime with partially hydrogenated tallow acid obtained from animal fat. Its main functions are to improve fabric softness, reduce static electricity buildup, reduce wrinkling, and provide water-repellent properties. The Commissioner for SARS claimed arrear duties and penalties totaling R3,377,732, contending that tetranyl was dutiable under tariff heading 3402.12 (Organic Surface-active Agents) of the Customs and Excise Act 91 of 1964. Colgate contended that no duty was payable as tetranyl fell under tariff heading 3809.91 (Finishing agents used in textile industries), which is non-dutiable. The matter proceeded to the KwaZulu-Natal High Court where expert evidence was heard from chemists on both sides regarding the properties and classification of tetranyl.
The appeal was dismissed with costs including those of two counsel. The order of the KwaZulu-Natal High Court was confirmed, classifying tetranyl under tariff heading 3809.91 as non-dutiable. No arrear duties were payable by Colgate-Palmolive.
A product containing surface-active properties is excluded from classification under tariff heading 3402.12 (Organic Surface-active Agents) of the Customs and Excise Act 91 of 1964 where the surface-active function is either not required or is only subsidiary to the main function of the preparation, as provided in the explanatory note to that heading. Where a product's main function is as a finishing agent and softening agent in the textile industry, and surfactancy is merely a subsidiary function, it is properly classified under tariff heading 3809.91 (Finishing agents used in textile industries) rather than heading 3402.12. The exclusionary proviso in heading 3809 ('not elsewhere specified or included') does not apply where the product would be excluded from the alternative heading by virtue of that heading's own exclusionary provisions. Classification must be determined by identifying the primary or main function of the product rather than focusing on subsidiary or incidental properties.
The court noted that there had been a perceived conflict in the affidavits regarding whether tetranyl constitutes a preparation, which led the initial judge to refer the matter to oral evidence. However, this became common cause during the proceedings that tetranyl is regarded as a preparation. The court also observed that there was an apparent dispute between the experts as to whether tetranyl has surface-active properties, with one expert maintaining it accumulated next to fabric and the other that it adsorbs to it (attaches to the fabric). The experts were agreed, however, that tetranyl is cationic in that it has a positive molecular charge. The court noted that surfactancy, while it may occur together with adsorption, was not a prerequisite to adsorption. The judgment also noted that the case had 'no precedential significance' as indicated in the heading of the judgment.
This case is significant for customs and excise law in South Africa as it clarifies the approach to tariff classification under the Customs and Excise Act 91 of 1964, particularly: (1) It confirms the three-stage process for classification established in earlier authorities; (2) It demonstrates the importance of identifying the main function versus subsidiary functions of a product when competing tariff headings may apply; (3) It illustrates the proper application of exclusionary provisions in tariff headings and explanatory notes; (4) It shows that where a product has multiple properties or functions, classification depends on identifying its primary or main function; (5) It demonstrates the role of expert evidence in determining the technical and chemical properties of products for classification purposes; and (6) It provides guidance on the interpretation of tariff headings in the Schedule to the Act, particularly the distinction between surface-active agents (heading 3402) and finishing agents (heading 3809). The judgment reinforces that the mere presence of surface-active properties does not automatically result in classification under heading 3402 if that function is subsidiary to the product's main purpose.
