Practical Analysis of Full Process of Import and Export Customs Brokerage: 6 Core Stages from Document Preparation to Release and Pickup

Strategic Position of Customs Declaration in Foreign Trade Chain

Compliant declaration of goods entering and leaving the customs territory directly determines the circulation efficiency and financial cost of the supply chain.In 2026,the customs supervision system is further upgraded,and the cross-verification mechanism between declaration data,logistics trajectory and foreign exchange flow is increasingly improved.A classification error may lead to 5%-20% additional taxes and fees,and a declaration delay may cause demurrage charges for the whole batch of goods.For foreign trade enterprises lacking a full-time customs team,the customs declaration link is not only a high-risk area,but also a key breakthrough for cost optimization.Zhongshen dismantles the complete customs declaration process into six operable stages,each corresponding to clear objectives,action lists and risk response plans.

Stage 1: Pre-qualification and Document Preparation

Objectives and Key Actions

The core objective of this stage is to ensure the legal access qualification of the declaration entity and goods.Key actions include: verifying the validity of import and export operation rights,confirming the status of customs code and credit rating,obtaining the certificate of origin and compliance certification documents from overseas suppliers.For commodities subject to license management,applications shall be submitted to the Ministry of Commerce or local licensing authorities in advance.At this stage,Zhongshen will assign Supervisor Ye to conduct a full scan of customer qualifications,identify expired and unrenewed filing information,and assist in completing pre-classification applications,so as to avoid the passive situation of incomplete documents found only after the goods arrive at the port.

Common Problems and Avoidance Strategies

Typical problems are concentrated in three categories: first,overseas documents do not meet customs endorsement requirements,such as the certificate of origin not marking the correct first six digits of the HS code; second,special goods lack supervision certificates,and pre-shipment inspection is not handled for used mechanical and electrical products; third,the trade mode is selected incorrectly,and temporarily imported and exported goods are declared as general trade.Avoidance strategies include establishing a document pre-review list and launching pre-shipment compliance review for high-risk goods.Zhongshen’s internal system automatically matches the latest regulatory policies,and when customers upload documents,the system will mark fields that do not conform to the 2026 new version of *Import and Export Goods Declaration Catalogue*.

Stage 2: Commodity Classification and Declaration Element Confirmation

Objectives and Key Actions

Accurate determination of HS code is the cornerstone of customs declaration compliance.At this stage,it is necessary to conduct technical decomposition of the material,function and structure of the goods,and determine the 10-digit code against *Tariff Explanatory Notes*.Key actions include: submitting classification pre-ruling application for disputed commodities,and preparing detailed composition descriptions and process flow charts for sensitive goods such as chemicals and textiles.Zhongshen’s classification team is composed of professionals with customs broker qualification.The classification team led by Ms.Fang handled 17 difficult classification cases involving new material products in the first quarter of 2026,and resolved disputes before declaration by communicating with the customs classification center in advance.

Common Problems and Avoidance Strategies

Common mistakes made by enterprises include: classifying goods generally only based on goods name,without considering differences in functional principles; confusing classification rules of special parts and general parts; failing to accurately calculate the value proportion of each component when classifying mixed material products according to main materials.The avoidance strategy requires establishing a classification decision tree,and tariff provisions and notes must be consulted for first-time imported goods.Zhongshen will establish an exclusive commodity database for each long-term cooperative customer,recording previous classification conclusions and customs audit results,forming traceable knowledge assets.When the tariff is adjusted in 2026,the system will automatically prompt the list of affected commodities to avoid declaration errors caused by using old codes.

Stage 3: Customs Declaration Form Filling and System Declaration

Objectives and Key Actions

The objective of this stage is to convert paper documents into structured information that meets customs data specifications.Key actions include: accurately entering header information such as consignor and consignee,mode of transport,transaction mode in the single window system,and filling in elements such as commodity serial number,name,specification model,quantity unit,unit price and total price one by one in the table body part.In 2026,the customs implemented a new version of customs declaration form,adding mandatory items such as "brand type" and "export preference enjoyment status".Zhongshen’s document making team adopts a double review mechanism: Ms.Yin is responsible for the preliminary review,focusing on checking the conversion relationship between quantity unit and legal unit,and Manager Lei is responsible for the final review,focusing on the logical consistency of price and currency.

Common Problems and Avoidance Strategies

High-frequency errors include: the specification model column is filled too simply,failing to cover all technical parameters required by the customs; the quantity unit column uses the enterprise’s usual unit instead of the customs legal unit; freight and insurance premiums are not correctly apportioned according to the requirements of transaction mode.The avoidance strategy emphasizes templated document making,and preset standard filling formats for conventional commodities.Zhongshen has developed an intelligent document making auxiliary tool,which can automatically capture key fields in invoices and packing lists and fill them into the corresponding columns of the customs declaration form.Manual only needs to check and verify,which reduces the average document making time per ticket from 40 minutes to less than 15 minutes.At the same time,the system has built-in latest 2026 declaration logic inspection rules,such as "freight column shall not be empty under FOB transaction mode",which automatically intercepts logical errors before submission.

Stage 4: Customs Inspection and Exception Handling

Objectives and Key Actions

The inspection link directly tests the authenticity of declaration.Key actions at this stage are to cooperate with the customs in physical verification,unpacking inspection or sampling and testing.In 2026,the customs inspection rate shows a differentiated trend: the inspection rate of high-risk commodities remains at 15%-20%,while that of conventional goods drops to less than 3%.Zhongshen is equipped with full-time inspection coordination personnel on site,and the inspection team led by Manager Yin has established a regular communication mechanism with the inspection departments of major ports.After receiving the inspection notice,the team will arrive at the site within 2 hours,sort out the goods placement sequence in advance,and prepare technical materials to ensure the efficient and smooth inspection process.

Common Problems and Avoidance Strategies

Main risks include: the actual status of goods is inconsistent with the declaration,such as undeclared wooden packaging; sampling and testing results conflict with the declared classification; the customs questions the authenticity of the price and requires supplementary explanation.The avoidance strategy emphasizes pre-simulation inspection,and take photos and file high-risk goods before shipment.Zhongshen has established an inspection case base to analyze the differences of inspection priorities and law enforcement scales at each port.In 2026,for cosmetics,medical devices and other commodities,the customs has strengthened the label identification review.Zhongshen will check the filing status of Chinese labels in advance to avoid the return of the whole batch of goods due to label problems.When there is an abnormality in inspection,the team will immediately launch an emergency plan and submit a situation statement or rectification plan within the time limit allowed by the customs to minimize the impact of the abnormality.

• Inspection exception types and disposal time limit:
  • Classification query: technical description shall be submitted within 24 hours,and extension to 3 working days can be applied
  • Price query: foreign exchange payment vouchers and price data of similar commodities in the same period shall be provided within 5 working days
  • Specification inconsistency: application for return or modification can be made.Modification shall be completed before release,and logistics cost shall be borne for return
  • Lack of supervision certificates: application for guarantee release can be made,and certificates shall be submitted within 7 working days

Stage 5: Tax Payment and Release for Pickup

Objectives and Key Actions

The objective of this stage is to complete tax calculation and payment,and obtain customs release instruction.Key actions include: checking the amount of the tax payment receipt issued by the customs system,completing payment through electronic payment or bank counter,and handling the pickup procedure with the release note.In 2026,the customs fully implemented the "two-step declaration" mode: enterprises can first pick up goods with summary declaration,and complete information can be supplemented within 14 days.Zhongshen’s financial docking team will calculate the tax cost in advance and issue a detailed bill to the customer to ensure the timely and full payment of taxes.For enterprises adopting the consolidated tax collection mode,the team will monitor the use of guarantee quota to avoid failure to release due to insufficient quota.

Common Problems and Avoidance Strategies

Typical problems include: the information of the tax payment receipt is inconsistent with the actual declaration,such as incorrect exchange rate application; the guarantee quota calculation error leads to the failure of consolidated tax collection; failure to pick up goods in time after release leads to additional storage fees.The avoidance strategy requires the establishment of a tax review mechanism,and independent verification is adopted for tax calculation.Zhongshen cooperates with a number of banks to provide tariff financing services for customers to ease capital pressure.At the same time,the team will track the goods release status in real time,and notify the customer to pick up the goods immediately after obtaining the release information to avoid demurrage charges.In 2026,paperless release is implemented in major ports.Zhongshen’s system can directly receive electronic release instructions,and customers no longer need to go to the site to collect paper release notes,which improves the pickup efficiency by more than 60%.

Stage 6: Subsequent Verification and Tax Refund Handling

Objectives and Key Actions

The follow-up work after customs declaration is also critical.The objectives of this stage include: processing trade manual verification,export proceeds verification,value-added tax refund declaration.Key actions are to sort out the tax refund copy of customs declaration form,value-added tax invoice,foreign exchange receipt slip and other documents,and submit tax refund application in the electronic tax bureau.In 2026,the tax bureau implemented "paperless tax refund": enterprises no longer need to submit paper documents,but need to ensure that electronic data fully matches the information of customs and foreign exchange administration.Zhongshen’s tax refund team will establish a tax refund ledger for customers,track the foreign exchange receipt status and declaration progress of each business,and ensure that the tax refund process is started within 30 days after customs declaration and release.

Common Problems and Avoidance Strategies

Common problems include: the commodity name on the customs declaration form is inconsistent with the value-added tax invoice,resulting in tax refund rejection; the difference between the foreign exchange receipt amount and the declaration amount exceeds the allowable range; the tax refund declaration is overdue and the qualification is lost.The avoidance strategy emphasizes the consistency management of documents.Zhongshen will unify the commodity name expression at the document making stage to ensure that the descriptions of customs declaration form,invoice and contract are consistent.The team will regularly compare the customs foreign exchange receipt data with the bank slip,and investigate the cause in time when differences are found.In 2026,the tax bureau has stricter tax refund review.Zhongshen will conduct simulated tax refund declaration in advance,identify potential doubts and prepare explanatory materials,shortening the tax refund cycle from an average of 60 days to less than 45 days.

Core Value and Service System of Zhongshen

Running through the six stages is the full-chain service mechanism of "pre-judgment - process control - post review" established by Zhongshen.The company is not limited to passively performing customs declaration operations,but actively intervenes in the front end of the customer’s trade process,provides classification suggestions at the product design stage,and plans logistics paths and document requirements at the contract signing stage.The policy database and case base formed by 20 years of industry accumulation enable the team to quickly respond to the changes of the regulatory environment in 2026.Each customer is equipped with an exclusive service team composed of three types of professionals: customs declaration,logistics and finance,to ensure zero loss of information transmission.Choosing Zhongshen is essentially transforming the customs declaration link from a cost center to a value creation node.Through compliance optimization and efficiency improvement,it directly improves the cash flow and profit margin of enterprises.
