The International Trade Administration Commission of South Africa has recommended the continuation of anti-dumping duty on hexagon bolts and nuts orginating in or imported from the People's Republic of China, effective 6 May 2011. This was based on the conclusion that expiry of the anti-dumping duty will likely lead to the contiuation or recurrence of dumping and the continuation of material injury to the SACU industry.
However, the expiry of anti-dumping duties on bolts manufactured by Ningbo Jinding Piece Company Limited would not likely lead to the contiuation or recurrence of dumping.
 
On 12 August 2016, the South African Revenue Service issued the notification announcing the termination of the above anti-dumping duty on bolts and nuts of steel from China with retrospective effect from 5 May 2016. The duty was terminated following its expiry as no request had been submitted for the initiation of a sunset review.
