On October 11, 2013, the Argentinian Ministry of Economy and Public Finance decided to initiate an anti-dumping investigation on imports of certain centrifugal pumps from China.
The products subject to investigation are classified under the following HS codes: 8413.7080 and 8413.7090.
The complaint was lodged by Motores Czerweny S.A. The investigation started on the day following the publication of the resolution in the Official Journal of the Argentinian Republic, i.e. on October 19, 2013.
 
On August 6th, 2014, the Argentinian authorities issued their preliminary decision (Resolution 122/2014, 06.08.2014). They decided to continue the investigation without imposing a provisional anti-dumping duty. Resolution 122/2014 was published in the Official Journal of the Argentinian Republic on August 7th, 2014.
 
On April 15th, 2015, the Argentinian authorities decided to impose a definitive anti-dumping duty on imports of centrifugal pumps originating in China (Resolution 243/2015, 15.04.2015).
The amount of the duty depends on the power of the pump. It ranges from USD 90.7 per item for a power between 0.25 and 0.50 HP to USD 278.3 per item for a power greater than 5.00 HP (up to 7.50 HP). For more details, please see the Annex to Resolution 243/2015.
This definitive anti-dumping duty entered into force on the day of the publication of the resolution in the Official Journal of the Argentinian Republic, i.e. on April 17th, 2015, and is applicable for a period of five years.

On 17 April 2020, the Argentinian authorities initiated a sunset review of the definitive duty imposed on the subject good from China. This follows the application lodged by MOTORES CZERWENY S.A. The definitive duty will remain in force for the duration of the investigation.

On 16 April 2021, the Argentinian authorities issued a resolution extending the definitive duty imposed on imports of centrifugal pumps from China following the conclusion of the sunset review. The amount of the duty depends on the power of the pump. It ranges from USD 90.7 per item for a power between 0.25 and 0.50 HP to USD 278.3 per item for a power greater than 5.00 HP (up to 7.50 HP). For more details, please see the Annex to Resolution 243/2015. The resolution extending the definitive duty entered into force on 16 April 2021.
