Chongming District Import and Export Trade Agency, Full-link Services of Local Port Declaration, Customs Clearance, Foreign Exchange and Tax Refund

Last month,we connected with Mr.Yin,the head of a PV mounting brackets export enterprise based in Changxing Island,Chongming.Previously,they handled export to Germany on their own,but were judged by the customs to have made incorrect HS code classification: they originally categorized the products under metal structural parts which enjoys a 13% export tax refund rate,while the actual correct category should be PV supporting components with a 9% tax refund rate.As a result,they not only had to return the overclaimed 420,000 RMB tax refund,but also were added to the customs control list.All subsequent shipments of theirs will be subject to inspection,leading to delayed delivery of 3 batches of orders.So far this year,we have encountered 11 local Chongming foreign trade enterprises that ran into similar pitfalls.

Three Common Practical Pitfalls for Chongming District Import and Export Enterprises

• Incorrect HS Code Classification: In 2026,Shanghai Customs has increased the intensity of classification verification for Chongming’s featured organic agricultural products and new energy supporting products by 30%.Many enterprises either ignore the RCEP classification detailed rules during self-classification,leading to extra 10%-15% tariff payment,or deliberately misclassify products to obtain higher tax refund rate,thus being judged as tax evasion and facing a maximum fine of 5 times the payable tax.
• Inconsistent Document Information: Many Chongming enterprises mark "Chongming" instead of "Shanghai,China" as the place of origin when applying for RCEP Certificate of Origin,which directly leads to the rejection of tariff preference by destination countries.In the first quarter of 2026,17 Chongming foreign trade enterprises lost nearly 2 million RMB of tax reduction benefits for this reason.In addition,some enterprises provide inconsistent information on contracts,invoices and packing lists,thus triggering customs control and inspection,which generates a minimum demurrage fee of 8000 RMB.
• Overdue Tax Refund Declaration: Over 80% of small and medium-sized foreign trade enterprises in Chongming do not have full-time customs operation staff,and often miss the 90-day tax refund declaration deadline after export,leading to direct loss of tax refund equivalent to 13% of the corresponding shipment value.Some enterprises even fail to obtain the tax refund for 3 years due to incomplete retained documents.

Practical Implementation Guide for Chongming Import and Export Agency Services

Key Points of Pre-submission Document Review

Before declaration of any import and export goods,the brand,model,material and specification in the declaration elements must be checked one by one to be fully consistent with the actual goods.For organic agricultural products exported from Chongming,pesticide residue test reports required by the destination country shall be completed 15 days in advance,and entered into the Shanghai Customs Green Agricultural Product Access System in advance to avoid return shipment after arrival.For imported production equipment,it shall be verified in advance whether mechanical and electrical import license is required,and pre-shipment inspection shall be completed for used equipment in advance,so as to avoid huge demurrage fees caused by failed customs clearance after arrival.

Pre-positive Risk Early Warning Scheme

In 2026,the EU has raised the anti-dumping duty on Chinese-origin PV mounting brackets to 27%.Chongming enterprises engaged in new energy supporting product export shall carry out trade compliance planning in advance.Eligible enterprises can apply for regional value accumulation under RCEP to avoid anti-dumping duty.For goods exported to RCEP member states,the issuing standards of Certificate of Origin shall be checked in advance to ensure the regional value proportion of the goods exceeds 40%,so as to successfully enjoy 0% tariff preference.

Optimized Operation Path for Tax Refund

Chongming’s green agriculture and high-tech export enterprises can apply for the "Featured Industry Tax Refund Green Channel" of Shanghai Customs.We will assist enterprises in sorting out qualification materials and submitting to the customs for review in advance.After approval,the tax refund cycle will be shortened from 3 months to 15 days.For enterprises with complete documents,we also provide tax refund advance service,and the tax refund can be received 3 days after shipment to ease capital pressure.

Chongming Import and Export Trade Compliance Risk Warning

Three red lines must never be crossed.First,never make false origin declaration.In 2026,customs inspection linkage of all RCEP member states has achieved full coverage.Once origin fraud is detected,the enterprise will be disqualified from any tariff preference for 5 years,and be added to the national dishonest list,thus all its import and export goods will be put under customs control and inspection.Second,never understate the shipment value.The AI price verification system launched by Shanghai Customs in 2026 has included the price benchmark database of all Chongming featured import and export products.Understatement of shipment value will directly trigger customs control,which leads to supplementary tax payment and a maximum fine of 3 times the payable tax.Third,never ignore the influence of public holidays in destination countries.For goods exported to Southeast Asia,booking shall be arranged 15 days in advance to avoid the Ramadan period.For goods exported to Europe and America,booking shall be arranged 20 days in advance to avoid the Christmas season,otherwise shipment rolling and port demurrage will occur,and the delivery order fee alone will increase by more than 2000 RMB.
