The International Trade Administration Commission of South Africa through a sunset review, has recommended that removal of anti-dumping duties on polyethylene terephthalate originating in or imported from Chinese Taipei, Republic of Korea and India would likely lead to the continuation or recurrence of dumping and to the recurrence of material injury. The anti-dumping duties were to expire on 6 October 2010.
The application was made by FC Dubbelman and Associates, on behalf of Hosaf, a division of Feltex Holdings (Pty) Ltd, being the only producer of the product in the Southern Africa Customs Union (SACU). The anti-dumping duties are therefore maintained as: Chinese Taipei - 75%, India - 54.1%, Korea - 19.7%.

The duty was extended on 3 March 2011 following the conclusion of a sunset review initiated on 23 July 2010.

On 29 January 2016, the International Trade Administration Commission of South Africa initiated a sunset review on imports of polyethylene terephthalate originating in or imported from Chinese Taipei, the Republic of Korea and India. The products subject to investigation are classified under the following HS code: 3907.60. The request for a review was lodged by Hosaf a division of PG Bison (Pty) Limited on 3 September 2015.

On 8 July 2016, the definitive anti-dumping duty imposed on the subject good from Chinese Taipei, Republic of Korea and India was extended and maintained.

On 18 June 2021, the International Trade Administration Commission of South Africa announced the initiation of a sunset review of the definitive duty imposed on imports of the subject good from India, Chinese Taipei and the Republic of Korea. This follows the application lodged by Safripol (Pty) Ltd.

On 2 July 2021, the International Trade Administration Commission of South Africa amended the notice announcing the initiation of the sunset review to include the products classified under the following HS code subheading: 3907.6, 3907.61.90 and 3907.69.90, from India, Chinese Taipei and the Republic of Korea.
