In 2026,Shanghai’s foreign trade import business continues to grow.Many enterprises often suffer from delays,extra costs and even cargo detention due to unclear division of customs clearance responsibilities when importing goods.Last week,Mr.Zhu’s company imported mechanical accessories from Germany.Due to unclear responsibility for the declaration link,it was required by customs to supplement documents,which delayed 3 days and directly affected production line scheduling.Import customs clearance is not a single-link matter,it involves collaboration of multiple parties,and clarifying responsibilities at each stage is the core to ensure smooth cargo customs clearance.This article will combine the latest 2026 customs policies to break down the responsible parties in the import customs clearance process,and explain how Zhongshen helps customers avoid risks.

Core Stages of Import Customs Clearance Process and Responsibility Division

Key Actions: Verify bill of lading,invoice,packing list,certificate of origin (requires electronic signature),commodity inspection customs clearance certificate (for partial cargo),import license (for mechanical and electrical products,etc.).

Common Problems: In 2026,customs requires certificate of origin to have electronic signature,but some enterprises still use paper version which leads to document rejection; failure to apply for automatic import license in advance for mechanical and electrical products causes customs clearance delay.

Role of Zhongshen: The team led by General Manager Yue will verify customer documents 10 days in advance,update the qualification audit list according to the new 2026 regulations,and helped Mr.Zhu supplement the certificate of origin with electronic signature to avoid delay.

4.Tax Payment: Handling of Tariff and Value-Added Tax

Stage Goal: Pay taxes on time to avoid late fees.

Key Actions: Confirm tax amount,pay on time.
