2026 Full Process Quotation and Compliance Operation Points for Proxy Import & Export Tax Refund

2026 Proxy Import & Export Tax Refund Quotation: Full Process Breakdown from Compliance to Implementation

In 2026,the General Administration of Customs updated over 1200 HS code regulatory rules.Preferential policies for RCEP member countries’ certificates of origin have been further tightened,and the coverage of the Carbon Border Adjustment Mechanism (CBAM) in European and American markets has expanded,leading to a continuous increase in tax refund compliance costs for foreign trade enterprises.Many export enterprises not only fail to get full tax refunds due to incomplete documents or wrong HS code classification but also may face customs inspection risks.As the core basis for service payment,proxy import & export tax refund quotations directly affect enterprises’ actual benefits and compliance risks.

Core Components of Proxy Import & Export Tax Refund Quotation

Zhongshitong’s proxy tax refund quotation system strictly complies with Shanghai Port regulatory requirements and national linkage service standards.The following is the 2026 benchmark quotation details:

It should be noted that the above quotations are benchmark prices,and actual fees will be adjusted according to factors such as the enterprise’s trade mode (EXW/FOB/CIF),cargo type (general cargo/hazardous chemicals/mechanical and electrical equipment),and customs declaration port.For example,proxy tax refund for hazardous chemicals requires additional documents such as MSDS and dangerous goods packaging certificates,and the service fee will increase by 20%.

Core Risks and Pitfall Avoidance Points for Proxy Tax Refund

Many enterprises are prone to falling into traps of hidden charges and compliance loopholes when choosing proxy tax refund services.Combined with practical cases in 2026,the following are key risk points to focus on:

• HS code classification error: In 2026,the customs control model was upgraded.Classification deviations will directly lead to inconsistent tax refund rates,or even be identified as false declaration,facing 10%-50% tax late payment fees.Zhongshitong’s risk control team will lock the correct code in advance through the pre-classification service of Shanghai Customs Classification Center to avoid such risks.
• Tax refund delay due to incomplete documents: Common missing documents include foreign exchange receipt slips,input invoices,inconsistent information between packing lists and customs declarations,etc.In March 2026,a hardware export enterprise in Shanghai was subject to customs control inspection due to a 0.5% deviation in cargo weight between the packing list and customs declaration,delaying the tax refund for 12 days and losing nearly RMB20,000 in capital costs.Zhongshitong will complete the pre-audit of the full set of documents before accepting the order to ensure complete information matching.
• Hidden charge trap: Some agencies will hide additional fees such as inspection fees,document exchange fees,and storage fees in their quotations.Zhongshitong’s quotation clearly marks all service items,with no hidden charges,and all additional fees need to be confirmed with customers in advance.
• Exchange loss risk: In 2026,the fluctuation range of the RMB exchange rate expanded,and foreign exchange settlement business without locked exchange rates may generate 5%-8% exchange losses.Zhongshitong’s foreign exchange settlement service provides real-time exchange rate locking to help enterprises avoid such risks.
