This order gives importers a tariff concession (essentially a discount or exemption on customs duty) for plate heat exchangers—industrial devices used to transfer heat between fluids by passing them between metal plates.
If you import plate heat exchangers that fall under customs classification 8419.50.90, this order lets you apply Item 50 of Schedule 4 to the Customs Tariff. This typically means paying reduced or zero duty compared to standard import taxes.
The concession took effect on 9 December 2008 and remains valid indefinitely unless formally cancelled or revoked under the Customs Act.
