Core Processes and Selection Points of Import and Export Customs Clearance Agents

For foreign trade enterprises engaged in import and export business,customs clearance is an unavoidable key link.Whether the goods can be released smoothly after arriving at the port and whether the subsequent tax rebates can arrive on time,the efficiency and compliance of the customs clearance link directly affect capital turnover and order delivery rhythm.Many practitioners often ask "where to find import and export customs clearance agents",especially in Shanghai,a major foreign trade hub,the service capabilities of local agents are the core concern of enterprises.Today we will systematically sort out the core processes of import and export customs clearance agents,and how professional institutions can help enterprises avoid risks and improve efficiency.

1.Preparatory Stage: Document Review to Reduce Compliance Risks

Stage Objective: Ensure all declaration documents comply with the latest customs requirements of 2026,and avoid declaration delays or cargo detention caused by incorrect documents.

Key Actions:

• Collectbasicenterprisequalifications(businesslicense,importandexportoperationrightcertificate,recordformforforeigntradeoperators,etc.);
• Verifycorecargoinformation(HScode,quantity,weight,certificateoforigin,commercialinvoice,packinglist,etc.);
• Confirmthecustomsclearanceresponsiblepartycorrespondingtothetradeterms(forexample,thesellerisresponsibleforexportcustomsclearanceunderFOBterms,andthebuyerisresponsibleforimportcustomsclearanceunderCIFterms).

Common Problems: Many enterprises fall into traps due to insufficient document preparation.For example,Ms.Gao’s garment trading company,when importing fabrics for the first time in 2025,failed to notice the 2026 customs adjustment to the HS code of "regenerated fiber fabrics",and incorrect classification led to cargo detention by the customs,delaying the delivery period by 12 days; another example is Ms.Song’s electronic accessories company,which was required to supplement the test report because the packing list did not mark the "anti-static packaging" logo,taking an extra 3 days.

Role of Zhongshen: We will arrange more than 3 specialists with over 5 years of experience to connect with the pre-declaration document review.For the 2026 customs updated tariff catalog,we will take the initiative to help customers recheck the HS code; at the same time,we provide standardized document list templates,marking the precautions for each document (for example,the certificate of origin must be issued by an official institution),allowing customers to complete the preparation 1-2 days in advance.For example,when Mr.Qian’s hardware trading company first cooperated,they were unfamiliar with the requirements for issuing "export tax rebate special invoices".Zhongshen specialists came to guide them in advance,avoiding subsequent tax rebate delays.

2.Customs Declaration and Inspection: System Operations to Improve Customs Clearance Efficiency

Stage Objective: Complete the declaration via the Single Window within the time limit stipulated by the customs,obtain the "Customs Final Review Receipt",and prepare for subsequent inspection and release.

Key Actions:

• Enterthedeclarationsystem:Synchronizecargoinformation,enterprisequalifications,tradetermsandotherdatatothecustomsSingleWindow;
• Uploadelectronicdocuments:EnsurethatformatssuchasPDFandimagesmeetthesystemrequirements(forexample,thesizeofasingle-pagePDFdoesnotexceed500KB);
• Followupthereviewstatus:Checkthefeedbackfromthecustomssysteminrealtime,andsupplementormodifyinformationinatimelymanner.

Common Problems: After the 2026 customs Single Window system update,incorrect electronic document upload format has become a frequent problem.For example,Mr.Wu’s home furnishing export company had their declaration returned 3 times because the product test report was in JPG format (the system requires PDF),delaying the process by 5 days; another example is Ms.Pu’s food import company,whose declaration failed because the commercial invoice did not mark the "country of origin",missing the shipping cutoff time.

Role of Zhongshen: We have the "fast declaration channel" certified by the General Administration of Customs,and can directly connect to the priority review queue of the Single Window system; at the same time,we have established an electronic document format verification tool to help customers check whether the format meets the requirements in advance,increasing the declaration success rate from 75% for enterprises operating on their own to 98%.For example,a machinery export company that cooperated with us last year obtained the final review receipt in only 4 hours through Zhongshen’s declaration,which was 3 days faster than operating on their own.

3.Inspection and Release: On-site Coordination to Avoid Delay Risks

Stage Objective: Pass the customs inspection smoothly (release directly if no inspection is required),obtain the "Customs Release Order",and the goods can be picked up from the port area.

Key Actions:

• Pre-inspectionpreparation:Sortoutthecargodetailedlistandmarkthepositionsofkeyinspectiongoods;
• On-sitecoordination:Arrangespecialpersonneltoassistthecustomsinunpackingandinspection,andprovidecargodescriptions;
• Problemhandling:Ifadiscrepancybetweencargoanddocumentsisfound(suchasquantitydifferences,incorrectmarkings),supplementsupportingmaterialsoradjustthedeclarationinformationinatimelymanner.

Common Problems: Discrepancy between cargo and documents is the main problem in the inspection link.For example,Ms.Gao’s fabric company was required to re-declare because they packed 2 extra boxes of samples (unreported),delaying the process by 7 days; another example is Ms.Song’s electronic accessories company,which was required to re-stick the "Made in China" logo on the cargo packaging because it was blurry,delaying release by 2 days.

Role of Zhongshen: We will conduct sampling checks on containers 1 day before the cargo arrives at the port to ensure consistency between cargo and documents; in case of inspection,the dedicated coordinator can arrive at the inspection site within 30 minutes,and is familiar with the latest 2026 customs inspection standards (such as the requirements for the "UN38.3" test report for lithium batteries),and can solve problems quickly.The following is a comparison of the inspection process between enterprises handling it on their own and Zhongshen’s agency:

4.Subsequent Settlement: Tax Rebates and Foreign Exchange to Improve Capital Turnover

Stage Objective: Complete foreign exchange receipt and payment and export tax rebate declaration quickly,and accelerate the capital recovery speed of enterprises.

Key Actions:

• ForeignExchangeReceiptandPayment:Verifyoverseaspaymentinformation,handleforeignexchangeaccountentryandsettlement;
• TaxRebateDeclaration:Organizedocumentssuchascustomsdeclarationforms,VATinvoices,foreignexchangeverificationforms,etc.anddeclarethroughthetaxrebatesystem;
• ReceiptFollow-up:Checkthetaxrebateprogressinrealtime,andremindenterprisestoverifythereceivedamount.

Common Problems: The most common problem is the late submission of tax rebate documents.For example,Mr.Qian’s hardware company failed to submit the VAT invoice within 90 days after the export date of the customs declaration form,resulting in a 2-month delay in tax rebates; another example is Mr.Wu’s home furnishing company,which was required to resubmit documents by the tax authorities because the foreign exchange verification form did not match the customs declaration form,delaying the process by 1 month.

Role of Zhongshen: We will organize all tax rebate documents within 3 days after the cargo is released,and declare through the tax authorities’ "fast tax rebate channel" (the green channel opened by Shanghai Taxation Bureau for foreign trade agencies in 2026); in terms of foreign exchange receipt and payment,we can provide real-time exchange rate references to help customers choose the best settlement time and reduce exchange loss.For example,a garment export company that cooperated with us last year received the tax rebate in only 15 days through Zhongshen’s service,which was 30 days faster than operating on their own.
