The EU is scheduled to levy a carbon border tax on screw imports this October. Some of Taiwan's screw manufactures indicated that some foreign customers have adopted screws that were produced by electric arc furnaces (EAF) rather than blast furnaces. The EAF's screw could ease European importers' costs.

EAF's screws can reduce carbon emissions greatly, and their prices are lower than blast furnace screws. However, it was required to provide many certifications and testing for exporting screws to Europe. Therefore, if the quality of the products doesn't match customers' requirements, the producers might face returning or canceling orders.
