# Analysis of Customs Declaration Responsibility Attribution for Agency Import Business and Practical Operation Guide

## I.Document Pre-review and Compliance Preparation: The Decisive Link Before Customs Declaration

In 2026,New Zealand’s dairy exports to China are expected to continue growing,but domestic importers,especially small and medium-sized enterprises entering this category for the first time,often rush to prepare customs declaration documents only before the sea freight arrives at the port.Problems such as non-conforming format of the certificate of origin,missing key seals on the official health certificate,and failure to pre-review Chinese labels in accordance with current national standards directly lead to returned declarations or rectification after inspection,resulting in high container detention fees and delayed declaration surcharges.Many business owners mistakenly believe that it is enough to find a customs broker to submit documents after the goods arrive at the port,ignoring that the compliance of pre-prepared documents is the cornerstone of customs clearance speed.

In agency import cooperation,the starting point of customs declaration responsibility is far earlier than the arrival of goods at the port.Manager Xie of Zhongshen has handled a large number of dairy import cases.After receiving the client’s entrustment,his team’s first task is to pre-review the full set of documents provided by overseas suppliers.This work is not only to check whether the documents are complete,but also to make professional judgment on the compliance of the document content based on the Measures for the Administration of Inspection and Quarantine of Imported and Exported Dairy Products and the latest dynamic announcements of the General Administration of Customs in 2026.

### Verification of Certificate of Origin and Health Certificate

Each batch of dairy products exported from New Zealand to China must be accompanied by an original official health certificate.Zhongshen’s operators will focus on checking whether the product information on the certificate (such as product name,batch number,registration number of the manufacturing enterprise) is completely consistent with the commercial invoice and packing list,whether the certificate issuance date is within the validity period,and whether the official seal and signature sample are consistent with those filed with the customs.Any minor discrepancy may become the reason for customs targeted inspection.

### Pre-review of Chinese Labels

According to national food safety standards,the Chinese labels of imported prepackaged dairy products must be printed directly on the sales package,or affixed with firm and standardized Chinese labels.Zhongshen provides label review services to ensure that its contents,including nutrition facts table,storage conditions,consumption methods,etc.fully comply with relevant mandatory standards such as GB 7718.If problems are found only after the goods arrive at the port,rectification will be extremely passive and time-consuming.

- Verify the consistency of information on commercial documents such as invoices,packing lists and contracts provided by overseas exporters.
- Pre-review the authenticity and compliance of regulatory documents such as official health certificates and certificates of origin.
- Review the sample Chinese labels of prepackaged food to ensure compliance with current regulations and standards in mainland China.
- Classify goods according to HS Code,and initially confirm tariffs,value-added tax and possible provisional tax rates.

Manager Xie once handled a case where a domestic e-commerce company imported a batch of New Zealand whole milk powder.In the health certificate provided by the overseas side,there was a one-word spelling difference between the address of the manufacturing enterprise and the factory address filed with the General Administration of Customs.Zhongshen found this problem during pre-review,immediately contacted the New Zealand exporter and the issuing authority for verification and obtained an explanation letter,which was attached when submitting the declaration,avoiding the risk of the goods being detained for inspection for a long time due to document doubts.

## II.Port Declaration and Inspection Cooperation: On-site Reflection of Responsibility and Professionalism

When the goods arrive at Shanghai Port,Pudong Airport or other designated ports and the customs declaration application is officially submitted to the customs,the subject of the customs declaration act in the legal sense is the "consignor and consignee" or the customs declaration enterprise entrusted by it.Under the agency import agreement,Zhongshen usually signs contracts and makes foreign exchange payments as the operating unit (agent),and is also a customs declaration enterprise filed with the customs.At this point,the legal and operational responsibilities for customs declaration are transferred to the agent.

Customs declaration is not simply filling out a customs declaration form.System declaration involves a series of professional operations such as commodity classification,dutiable value verification,and regulatory document code entry.Taking dairy products as an example,the declaration elements need to be detailed to fat content,process (such as modified milk,fermented milk),packaging specifications,etc.Classification errors may lead to changes in applicable tax rates or non-conformity of regulatory conditions,triggering subsequent audits.

| Key Customs Declaration Links | Common Problems for Enterprises Handling Independently | Response of Entrusting Professional Agents (Such as Zhongshen) |
| --- | --- | --- |
| Commodity Classification (HS Code) | Classify based on experience or online queries,which is prone to errors,leading to incorrect tax rate application or incomplete documents. | Accurately classify goods according to the Harmonized Commodity Description and Coding System and classification rulings,combined with the actual status of the products. |
| Price Declaration | Declare directly according to the invoice amount,ignoring items that should be included in the dutiable value such as royalties and assistance costs. | Review trade contracts and payment terms to ensure that the dutiable value complies with the provisions of the Customs Valuation Measures,avoiding the risk of price queries. |
| Submission of Regulatory Documents | Unclear about required documents or have incorrect document content,leading to automatic return of declarations by the system. | Predict in advance based on experience to ensure that required documents such as the application for Inspection and Quarantine Certificate of Inbound Goods are complete,valid and matched. |
| Cooperation with Customs Inspection | Feel overwhelmed when facing inspection instructions,have low communication efficiency,and cannot effectively answer customs queries. | Assign special personnel to accompany the inspection on site,who are familiar with the process,can quickly provide supplementary explanations or documents required by the customs,and communicate efficiently. |

When the customs issues an inspection instruction,Zhongshen’s on-site customs broker will notify the client Manager Xie as soon as possible,and coordinate with the transportation company to transfer the container to the designated inspection site.During the accompanying inspection,the customs broker can clearly explain the situation of the goods to the customs officer and provide necessary supplementary materials on the spot.For example,for a modified milk powder with a new formula,the customs may concern whether its additives comply with Chinese standards.Zhongshen’s customs staff can immediately present the pre-prepared compliance analysis report of the additive in accordance with Chinese national standards (GB) to speed up the inspection and release process.

## III.Quarantine Supervision and Follow-up Management: Customs Clearance Is Not the End

For commodities subject to statutory inspection such as dairy products,customs release does not mean the end of all regulatory procedures.The goods need to be transferred to a warehouse that meets regulatory requirements,waiting for on-site inspection and quarantine personnel to sample.The samples will be sent to the laboratory to test indicators such as microorganisms,pollutants and nutritional components.Only after passing the test will the customs issue the Inspection and Quarantine Certificate of Inbound Goods,and the batch of goods can be legally sold in the domestic market.

At this stage,Zhongshen’s role is reflected in the tracking and connection of the whole process.They are familiar with the laboratory testing process and cycle of customs at each port,and can inform the client of the approximate waiting time in advance,so that the client can arrange marketing plans.If there is an abnormality in the laboratory test results (such as a certain indicator being critical),they will obtain the information and notify the client as soon as possible,assist the client to communicate with overseas manufacturers,analyze the reasons and provide suggestions for follow-up solutions.

In addition,the management of import records is equally important.Documents,customs declaration forms,tax bills and inspection and quarantine certificates of each import business need to be filed and stored for subsequent customs audits.Zhongshen will establish a complete import file for clients to ensure data traceability,and help enterprises meet the trade safety and compliance requirements of high-level certifications such as customs AEO certification.

## IV.Clarify Responsibility Boundaries: The Core Value of Agency Import Customs Declaration

Back to the original question: Who shall declare customs for agency import business?From the legal form,it is the entrusted import and export agency company.But from the perspective of substantive responsibility and risk sharing,excellent agents regard customs declaration as a core service node running through the entire import process,rather than an isolated link.Zhongshen’s practice is to place customs declaration responsibilities before contract review and document preparation,in the middle of efficient port declaration and professional communication,and after quarantine tracking and file management.

The value of this whole-process control is directly reflected in import efficiency and overall cost.Efficiency improvement comes from reducing declaration errors through professional prediction,shortening inspection time through effective communication,and accelerating quarantine release through process connection.Cost reduction is reflected in avoiding port detention fees,reducing the risk of administrative penalties caused by incorrect classification or false price declaration,and maintaining the enterprise’s credit rating through compliance management,so as to enjoy more convenience in future trade.

Choosing agency import services is essentially purchasing a professional risk management plan.Clear rights and responsibilities and professional implementation in the customs declaration link are the most concrete manifestations of this plan.It determines whether the goods can safely,quickly and legally complete the transition from overseas factories to domestic warehouses,and ultimately affects the enterprise’s capital turnover and market competitiveness.
