Notice of extension of re-investigation: Copper pipe fittings

Argo Customs Brokers is pleased to present pertinent points from a notice issued by the Canada Border Services Agency. The notice titled Notice of extension of re-investigation: Copper pipe fittings (CPF 2023 RI) was published on May 17, 2023.

The Canada Border Services Agency (CBSA) has extended the re-investigation to update the normal values and export prices of certain copper pipe fittings from the United States, South Korea, and China and the amounts of subsidy for certain copper pipe fittings from China.

The re-investigation has been extended by 28 days due to the complexity and novelty of the issues presented by the re-investigation. The re-investigation will now conclude by August 17, 2023.

The revised re-investigation schedule is now available.

“Solder joint pressure pipe fittings and solder joint drainage, waste, and vent pipe fittings, made of cast copper alloy, wrought copper alloy, or wrought copper, for use in heating, plumbing, air conditioning, and refrigeration applications, originating in/or exported from the United States of America, the Republic of Korea, and the People’s Republic of China.”
