Cheng Shin's Taiwanese parent currently supplies the Taiwanese market and functions as the company's global operational hub; its Shanghai and Xiamen plants supply the China market (at 50 % of revenues, the company's largest market); and its Thai facility, located in the Bangkok-area Rayong Industrial Land, supplies the European, Asian, and Australian markets.
正新泰國廠副總經理林鈺榆滿意地說。目前正新輪胎的全球布局是，台灣母廠做為全球運籌中樞，並且供應台灣市場需求；最大市場中國（佔營業額 5 成）由設於上海、廈門等大陸廠供應；新興的南亞、東南亞市場、澳洲及大部份的歐美市場則由這座位於羅永工業區的廠區供應。
