Disperse dyes are one of the export products that benefit most from the free trade between China and South Korea. At present, some products from China to South Korea can be exempted from certain import tariffs with the certificate of origin of the Asia-Pacific Trade Agreement. After the China-South Korea Free Trade Area Agreement comes into effect, both the products that will benefit and the scope of tariff reductions will increase significantly. According to statistics, the Taizhou Inspection and Quarantine Department issued a total of 1,687 Asia-Pacific Agreement Certificates of Origin last year, of which 1,350 were for South Korea, accounting for 80% of the total; the value of the goods reached US$57 million, with the number of copies and the amount increasing by 7.0% and 8.6% respectively year-on-year. The number of visas and the amount of visas have maintained growth for three consecutive years, and the products involve disperse dyes and other aspects.
