Dongguan Import Customs Clearance Agency, How to Choose Full-Process Service?

Dongguan Import Customs Clearance Agency: Full-Process Breakdown and Risk Aversion Guide

In 2026,as a core manufacturing city in the Guangdong-Hong Kong-Macao Greater Bay Area,Dongguan sees a continuous rise in import demand for industries including electronic information,intelligent equipment,new energy and others.In the first half of the year alone,imports of electronic components through Dongguan Port increased by 18% year-on-year,and imports of mechanical parts increased by 12%.Import customs clearance is a key node connecting international transportation and domestic production.Once problems such as document missing,code error and others occur,it will lead to container detention fees and storage fees in minor cases,and in severe cases,it will face customs penalties and affect enterprise credit.Combined with the practical experience of Zhongshen,this article systematically sorts out the core process of Dongguan import customs clearance and the value of agency services.

1.Pre-Import Preparation: Clarify Compliance Requirements to Avoid Early Omissions

The core goal of this stage is to complete the pre-customs clearance work,ensure complete documents and accurate commodity codes,and clear obstacles for subsequent declaration.

• Key Actions:
  • Confirm the supervision conditions of imported goods: such as 3C Certification (for electronic and electrical products),Automatic Import License (for mechanical and electrical products),Endangered Species Certificate (for special animal and plant products),etc.which need to be checked one by one according to commodity attributes
  • Prepare basic documents: Bill of Lading (B/L),commercial invoice,packing list,trade contract,certificate of origin (if tariff preference is required)
  • Confirm commodity coding (HS Code): Query through the Tariff Schedule of the General Administration of Customs of China,or consult professional institutions.Wrong coding will directly affect tariff calculation and supervision requirements
• Common Problems:
  • Commodity coding classification deviation: For example,misclassifying ordinary electronic components into categories that require 3C Certification,resulting in extra certification costs
  • Missing supervision documents: For example,importers of used mechanical and electrical products fail to apply for pre-shipment inspection certificate in advance,so the goods cannot be declared after arriving at the port

Role of Zhongshen: Arrange dedicated personnel to connect with customers,issue the Pre-Customs Clearance Document Checklist according to commodity details,and assist in contacting third-party institutions to confirm HS Code for complex commodities such as new energy batteries; if customers miss supervision documents,we can assist in expediting the processing of 3C Certification,Automatic Import License and other documents to avoid delays.Ms.Xu,purchasing manager of an electronics factory in Dongguan,almost had a batch of South Korean chips detained when imported in April 2026 because she did not confirm that some models required 3C Certification.Zhongshen only took 2 days to assist in completing the reissuance of the certification,and the goods cleared customs smoothly.

2.Declaration After Goods Arrival: Submit Accurate Data to Speed Up Customs Clearance Review

This stage requires completing customs declaration and tax payment,which is the core link affecting customs clearance speed.

• Key Actions:
  • Exchange for delivery order: Exchange the bill of lading for the delivery order (DO) at the shipping company,and pay attention to whether the bill of lading endorsement is correct
  • Single Window declaration: Enter customs declaration information (commodity name,quantity,value,origin,etc.) and submit to customs for review
  • Tax payment: Calculate tariffs and value-added tax according to the tax rate corresponding to the HS Code (some commodities can enjoy tax reduction or exemption),and complete payment through the Single Window
• Common Problems:
  • Inconsistent declaration data with actual goods: For example,the deviation between the weight on the packing list and the actual weight exceeds 5%,resulting in customs rejection of the declaration
  • Wrong tax calculation: Failure to deduct reasonable discounts leads to overpayment of tariffs

Role of Zhongshen: Connect with shipping companies to exchange delivery orders efficiently,avoiding container detention fees caused by document exchange delay; arrange customs declarers with more than 10 years of experience to enter data,and implement a "three-level review" mechanism (declarer preliminary review → supervisor re-review → manager final review),with an accuracy rate of 99%; provide customers with a Tax Estimation Form in advance,marking the calculation basis of tariffs and value-added tax,avoiding capital occupation exceeding expectations.

3.Inspection and Release: Cooperate with Customs Inspection to Complete Customs Clearance Quickly

This stage requires cooperation with customs inspection to ensure that the goods are consistent with the declaration information,and obtain the release instruction.

• Key Actions:
  • Cooperate with inspection: When the customs requires open-box inspection,provide the storage address of the goods,arrange personnel to accompany,and organize the goods to be inspected
  • Solve inspection problems: If inconsistency between goods and documents is found (such as deviation of brand and model),supplementary materials shall be provided in time
  • Collect release certificate: After customs approval,obtain the delivery order and arrange domestic transportation
• Common Problems:
  • Low inspection efficiency: Chaotic goods stacking leads to prolonged customs inspection time
  • Inconsistency between goods and documents: For example,declaring "new machinery" but actually used equipment,facing the risk of goods detention

Role of Zhongshen: Confirm the storage location of the goods with customers in advance,organize the goods to be inspected and mark key information,reducing the average inspection time from 4 hours to 1.5 hours; if there is inconsistency between goods and documents,we communicate with the customs in time,assist in providing supplementary materials such as original factory statements and test reports,and shorten the goods detention time as much as possible.In May 2026,the used equipment imported by a machinery company in Dongguan was inspected due to declaration model deviation.After Zhongshen assisted in providing the factory departure certificate,the release was completed in only 1 day.

4.Follow-up Settlement and Verification: Complete Closing Work to Avoid Subsequent Risks

This stage requires completing closing work such as expense settlement and foreign exchange verification to ensure a closed process.

• Key Actions:
  • Settle customs clearance expenses: including tariffs,value-added tax,customs declaration fee,storage fee,container detention fee (if any),etc
  • Foreign exchange verification: Complete verification with the State Administration of Foreign Exchange by virtue of customs declaration form and foreign exchange receipt and payment vouchers
  • Document archiving: Organize customs declaration forms,tax payment vouchers and other materials for future reference
• Common Problems:
  • Opaque expenses: Hidden expenses (such as inspection service fee) are not notified in advance
  • Delayed foreign exchange verification: Affecting the enterprise’s subsequent export tax refund qualification

Role of Zhongshen: Provide a detailed Customs Clearance Expense List,marking the calculation basis for each item (e.g.tariff = dutiable price × tax rate),with no hidden expenses; assist customers to complete foreign exchange verification,connect with banks and the State Administration of Foreign Exchange,and ensure completion within 3 working days; all materials are archived electronically,and customers can inquire at any time.
