With the deepening of the Yangtze River Delta integration strategy and the advancement of the construction of Chongming Ecological Island,in 2026,the Shanghai Customs will further strengthen the management of imported goods entering Shanghai.The compliance requirements of enterprises are being further upgraded.Traditional enterprises that rely on "template-based" operations are facing three challenges: the increasing complexity of the filing process,the stricter review of environmental protection qualifications,and the prolonged tax refund period.

The exclusive red benefit overlooked by 90% of enterprises in Chongming: ecological trade subsidies

Many enterprises only focus on basic processes,but miss the policy dividends of Chongming District.Starting from 2026,enterprises with an import and export volume of over 50 million yuan and an environmental protection rating of A can apply for support.0.2 yuan per US dollarExport subsidies (with a maximum amount of 1 million yuan); for enterprises importing advanced environmental protection equipment,the tariff rate can be reduced by 15% (subject to prior registration with the District Economic and Information Commission).

In addition,cross-border e-commerce enterprises can enjoy the "enter the zone and get tax refund" policy by conducting "9810 overseas warehouse export" through Chongming Comprehensive Bonded Zone,and can receive tax refunds 2-3 months earlier than the traditional model.

There are three urgent actions that can be implemented this week.
