AMSTERDAM, The Netherlands - Bike Europe’s email newsletter of last Tuesday (September 2) on the anti-dumping duties in place for bikes imported from China and some other Asian countries related to Oyama’s growing sales position on the European market raised questions on why certain companies are exempted from these measures and others not?
For why Oyama and Ideal China are exempted from the 48.5 anti-dumping duties on bikes made in China (and other Asian countries) and exported to Europe; see the pdf’s on this page. – Photo Bike Europe
