Where manufacturers in Thailand must pay fees of THB0.7 per kilogram of finished product (an amount equal to 10-20 % of total production costs) for the treatment of wastewater generated by the galvanizing process, Chinese manufacturers pay nothing. This has enabled them to export low-cost steel to the US and Europe in such high volumes that many nations have long levied anti-dumping tariffs of 60-200 % on China's steel products.
由於中國的環保成本低，以電鍍製程的廢水處理為例，泰國一公斤成品處理費為 0.7 元泰銖，高達總成本的 1-2 成，而大陸幾乎不需此費用，因此能以低價大量傾銷歐美，早已引起各國課徵懲罰性的反傾銷稅（60 % - 200 %）。
