The Chinese government promotes exports of alloyed steels with tax rebates of 9 to 13 percent on the general export tax of 17 percent. To get the most tax-beneficial classification as alloyed steels, Chinese steel producers add cheap alloy boron agent to steels specified by the customer as non-alloy qualities. Although the boron quantities are up to twice as high as permitted, Chinese steels are marketed in the EU as unalloyed steels.
Boron in steel improves the uniformity of the hardness of the steel. But if weld ability and elasticity are required, typically for unalloyed steel, a higher share of boron can be particularly harmful including welding cracks.
China’s steel exports are estimated to reach at least 85 million tonnes this year, up by 43 percent year-on-year. Chinese exports of steel products in which boron is typically added represent more than 50 percent of the total Chinese export volume.
“Not only does China promote exports of its excess steel production by targeted product tax advantages, but Chinese steel qualities also confuse the markets as Chinese producers exploit the export tax regime. The EU market surveillance authorities are now required to eliminate the risk of misleading use of the CE mark”, Eurofer Director General Axel Eggert says. “Steel processors must be protected from being exposed to wrongfully declared qualities to the risk of serious economic disadvantages.”
