Goods Detained Due to Discrepant Customs Declaration Documents? What Common Pitfalls Can a Proxy Company Help You Avoid?

Customs Declaration for Foreign Trade Enterprises: 3 Real Pain Points Encountered by Director Chen

In 2026,Director Chen of an electronic accessories export enterprise in Shanghai has been worried recently: A batch of goods shipped to Southeast Asia was detained by customs during customs declaration last month,because the product model on the packing list did not match that on the customs declaration form.Although it was only a clerical error,it took 3 days to revise documents back and forth,which not only delayed the delivery date,but also resulted in penalty paid to the client.Many foreign trade practitioners have encountered similar problems.This article combines real cases to discuss what practical problems a customs declaration broker can help enterprises solve.

Pain Point 1: Goods Detained Due to Discrepant Documents,Root Cause is "Information Transmission Gap"

Pain Point Performance: Director Chen’s enterprise has 3 salespersons in charge of orders from different regions,and the format of customs declaration materials submitted by each salesperson is inconsistent — some use Excel spreadsheets,some use PDF scans,and some even miss filling in the sub-item of the product HS Code.For the batch of goods last month,the salesperson mistakenly wrote the model of "fast charging charger" as "ordinary charger",resulting in inconsistent information on the customs declaration form,packing list and bill of lading,which triggered an automatic alert from the customs system,and the goods were detained for 3 days after on-site inspection.

Root Cause of Pain Point: The internal document processing process of foreign trade enterprises is scattered,salespersons lack professional customs declaration knowledge,and are not familiar with the latest customs document specifications (such as required fields of electronic documents updated by the General Administration of Customs of China in 2026); meanwhile,enterprises do not have a dedicated customs declaration team,and the document review link is missing,leading to gaps in information transmission.

Solutions from Zhongshen:

• Establish exclusive document templates for each client,unify fields such as HS Code query,product model marking and packing details,to avoid format confusion;
• Equipped with more than 3 licensed customs declaration reviewers,who conduct "three-level review" for customs declaration materials of each batch of goods: after submission by the salesperson,the reviewer first checks basic information,then the supervisor rechecks the accuracy of the HS Code,and finally conducts another verification before pre-entry into the customs system;
• Synchronize the latest 2026 policy updates of the customs (such as new customs declaration rules for cross-border e-commerce),notify clients in advance to adjust document content,avoid discrepancies caused by policy changes.

After Director Chen cooperated with Zhongshen,the document review link is handled by dedicated personnel,the customs declaration form passing rate has reached 100% in the past 3 months,and there has been no more goods detention.

Pain Point 2: Cumbersome Foreign Exchange Settlement and Purchase Process,Root Cause is "Poor Connection Between Enterprise Qualification and Policies"

Pain Point Performance: Director Sun of a clothing export enterprise in Shanghai recently encountered a foreign exchange settlement problem: A payment of 100,000 US dollars received last month could not be settled directly because the enterprise did not activate the advanced permission of the "Goods Trade Foreign Exchange Monitoring System"; he went to the bank 3 times and submitted 5 proof documents,but the application was still rejected due to "insufficient verification of trade background authenticity",which delayed the payment to the supplier.

Root Cause of Pain Point: In 2026,the State Administration of Foreign Exchange has stricter verification on goods trade settlement,requiring "four-document matching" proof materials including customs declaration form,bill of lading,contract and invoice; however,many small and medium-sized foreign trade enterprises do not have dedicated foreign exchange operation specialists,and are not familiar with the details of "four-document matching" (such as whether the payment terms on the contract match the trade method on the customs declaration form),resulting in failed verification.

Solutions from Zhongshen:

• Handle the permission activation of "Goods Trade Foreign Exchange Monitoring System" for clients,no need for clients to go to the bank in the whole process;
• Establish a "four-document matching" review mechanism: check the consistency of contract,invoice and packing list before customs declaration,to ensure complete documents during settlement;
• Connect with bank foreign exchange specialists,provide one-on-one guidance for foreign exchange settlement and purchase,and help clients select the optimal settlement method based on the 2026 new policies (such as preferential policies for cross-border RMB settlement) to reduce exchange rate loss.

After Director Sun’s enterprise cooperated with Zhongshen,the settlement time was shortened from 7 days to 2 days,and recently saved 1.2% of exchange rate cost by using cross-border RMB settlement.

Pain Point 3: Delayed Export Tax Refund,Root Cause is "Delayed Document Submission and Deviation in Policy Understanding"

Pain Point Performance: Director Yue of a household goods export enterprise in Shanghai recently found that the tax refund for a batch of goods exported in October last year did not arrive until March this year,2 months later than expected.The reason is that in the tax refund materials submitted by the enterprise,the "export date" on the customs declaration form is 3 days different from the "shipment date" on the bill of lading,and the tax authority required the enterprise to supplement the "certificate of goods retention at the port",which took 1 month to complete all materials.

Root Cause of Pain Point: In 2026,the tax authority has shifted the focus of export tax refund verification to "document consistency",requiring that the dates on the customs declaration form,bill of lading and manifest must match; however,many enterprise customs declarers do not understand the difference between "shipment date" and "export date",leading to non-compliant submitted materials; meanwhile,enterprises do not have dedicated personnel to track the tax refund progress,so they miss the optimal submission time.

Solutions from Zhongshen:

• Generate a "tax refund document list" for clients within 3 working days after customs declaration,including all required materials such as customs declaration form,bill of lading,manifest,contract and invoice,and ensure that the date and amount of all documents are completely consistent;
• Equipped with dedicated tax refund specialists,who track the tax refund progress of each batch of goods,and remind clients to supplement materials in time if required;
• Synchronize the 2026 new tax refund policies of the tax authority (such as the expansion of "paperless tax refund" coverage to all general trade exports),help clients prepare electronic materials in advance,and speed up the tax refund arrival time.

After Director Yue’s enterprise cooperated with Zhongshen,the average tax refund arrival time was shortened from 5 months to 2.5 months,and the capital turnover efficiency increased by 40%.
