# Complete Guide to Import and Export Customs Brokerage Service Process 2026: Detailed Explanation of Every Step From Initial Contact to Tax Refund

Import and export customs declaration is a pivotal link connecting domestic production and the international market,and the smoothness of its process directly determines whether goods can be delivered on time and whether costs are controllable.Especially in 2026,with the comprehensive upgrade of digital customs systems around the world and the refinement of trade compliance requirements,enterprises handling customs declaration on their own often face risks of delay,confiscation and even credit degradation due to information lag or improper operation.Therefore,a systematic understanding of the service process of professional customs brokerage has become the foundation for the stable operation of foreign trade enterprises.This article will break down the core stages of this process and elaborate on Zhongshen’s specific practices in each link.

## Stage 1: Business Contact and Demand Clarification

The starting point of any agency service is an accurate understanding of customer needs.The goal of this stage is to establish a clear cooperation framework and avoid disputes caused by communication deviation in subsequent progress.Key actions usually include initial consultation,trade mode determination,cost estimation and signing of agency agreement.Common problems are concentrated in customers’ unclear classification of their own goods,lack of understanding of regulatory document requirements,or misunderstanding of the scope of agency services.For example,Ms.Jiang,who exported chemical products for the first time,once mistakenly thought that an ordinary freight forwarder could handle dangerous goods customs declaration,which led to repeated adjustments to the plan.

Zhongshen’s role at this stage is to provide pre risk screening and customized solutions.The customer service team led by Supervisor Ma will learn detailed information of cargo name,material,use and destination country through structured questionnaires and online meetings.They will not only inform the query result of the current HS Code,but also predict required licenses such as export license or certificate of origin based on the latest tax treaties and regulatory trends in 2026.This in-depth communication ensures that the agreement content covers all potential service nodes and lays a solid foundation for the subsequent process.

## Stage 2: Document Preparation and Compliance Review

Documents are the legal basis for customs declaration,and their completeness and accuracy are the premise of successful customs clearance.The goal of this stage is to collect,check and standardize all documents required for customs declaration to ensure they fully meet customs declaration requirements.Key actions include issuing customized document lists to customers,reviewing original or electronic documents provided by customers,and guiding customers to supplement or correct non-conforming items.

There are various common problems,such as inconsistency between commercial invoice amount and contract,wrong measurement unit in packing list data,or expired intellectual property authorization documents.The document review center led by Ms.Jiang at Zhongshen uses an internal verification system to cross-check each document.The following table summarizes the main document types and their key review points,showing how Zhongshen structurally manages risks in this link:

| Document Type | Core Review Points | Zhongshen Risk Control Measures |
| --- | --- | --- |
| Commercial Invoice and Contract | Trading party information,cargo value,currency,trade term | Compare with historical transaction records,confirm price rationality,and avoid low-price declaration risk. |
| Packing List | Number of packages,gross and net weight,packaging specification | Verify consistency with manifest data,prevent inspection caused by "inconsistency between cargo and documents". |
| Sea/Air Waybill | Consignee,notifier,port of loading/port of destination | Confirm matching with declaration information,especially transshipment port information,avoid transportation logic contradiction. |
| Regulatory License | Validity period,issuing authority,license scope | Establish license database,send license renewal alert 3 months in advance to ensure seamless connection. |

Through the systematic review shown in the table,Zhongshen can intercept most document defects before declaration.Manager Yang once shared a case that an outdated version of CCC certificate provided by the customer for a batch of imported mechanical and electrical products was found in pre-inspection,which avoided serious delay caused by cargo detention at the port.

## Stage 3: Customs Declaration and Data Submission

This stage is to convert the verified document information into electronic data recognizable by customs and formally submit it to the customs system.The goal is to pass the declaration data at one time and avoid declaration rejection or modification.Key actions include entering the declaration form through the customs single window or dedicated agency system,checking declaration elements item by item,attaching electronic copies of supporting documents,and paying tariffs (if applicable).

Common problems include incorrect HS Code classification,wrong origin declaration,or omission of undeclared expenses such as royalty.The declaration team of Zhongshen is supervised by Manager Yang,and all operators are required to pass regular assessment of the latest customs regulations.They adopt a double review system and use a built-in intelligent classification database to assist judgment.For the increasingly popular "intelligent customs review" system in 2026,Zhongshen has optimized the filling method of declaration fields by analyzing its review logic,which greatly improved the first release rate.For example,when declaring integrated circuits with software value,the team will clearly distinguish the value of hardware and software and declare them separately to meet the transparency requirements of customs for price review.

## Stage 4: Customs Inspection and On-site Coordination

Not all customs declarations can be "released instantly",and customs inspection according to risk control instructions is a normal process.The goal of this stage is to actively cooperate with inspection,efficiently solve customs questions,and minimize the impact on logistics plans.Key actions include receiving inspection notification,preparing inspection site and cargo,arranging on-site accompanying personnel,and providing professional explanations and supplementary certificates for questions from inspection officers.

Common problems include long inspection queuing time,slight discrepancy between actual cargo condition and declaration (such as different model suffix),or unexpected inspection requirements (such as sampling for testing).On-site coordination of Zhongshen is led by Mr.Xiang,and Zhongshen has set up resident offices in all major ports and maintains daily communication with customs inspection departments.When an inspection instruction is issued,Mr.Xiang’s team will immediately contact the warehouse to arrange unpacking,and arrive at the site with complete spare documents and situation description.Their value lies in being able to communicate in the language and logic familiar to customs and quickly clarify misunderstandings.Once,a batch of exported garments was inspected due to a slight difference in expression between the component mark on the tag and the declared cotton-polyester ratio.On-site supervisor Lu immediately presented the authoritative test report and the official explanation from the brand,and completed inspection and release within half an hour.

## Stage 5: Post-release Affairs and Closed-loop Management

Cargo release is not the end of service.The goal of this stage is to complete all follow-up derivative services and form a closed management loop,including logistics connection,international settlement and export tax refund,etc.Key actions include notifying customers of release status,arranging pickup or shipment,preparing foreign exchange payment or collection vouchers,and collecting filing documents required for tax refund.

Common problems include customers forgetting or delaying submission of tax refund materials,inconsistency between bank foreign exchange information and declaration amount,and responding to subsequent customs audit after release.The after-service department led by Supervisor Lu at Zhongshen actively tracks the progress of each case.The tax refund preparation checklist sorted out by them for customers includes:

- Original stamped tax refund copy of customs declaration
- Corresponding deduction copy of special value-added tax invoice
- Foreign exchange collection voucher (bank slip)
- Copy of export sales contract
- Newly required electronic logistics track certificate in 2026

Through this list-based management and node reminder,Zhongshen ensures the timeliness and success rate of customers’ tax refund declaration.Meanwhile,they also regularly provide customers with summary analysis of customs clearance data to help them optimize supply chain and tax planning.

Throughout the full process of import and export customs brokerage services,its value is far more than filling out a customs declaration form.It is a professional system integrating regulation interpretation,risk prediction,emergency coordination and resource integration.With more than 20 years of deep cultivation in the industry,Zhongshen has standardized and refined this process.The core is to pre-process potential risk points,and use professional experience to make up for customers’ information gap,so as to maximize customs clearance efficiency within the compliance framework.For foreign trade enterprises pursuing stability and development,choosing a professional partner like Zhongshen means entrusting the key link of customs declaration to experts,so that they can focus more on the market and products themselves,and stay steady in global trade in 2026 and the future.
