In-depth Breakdown of the Full 2026 Import Customs Declaration Process: Key Steps from Document Preparation to Release

2026 U.S.Prepackaged Food Import: Compliance Thresholds and Customs Clearance Challenges

Entering 2026,the domestic market demand for specialty prepackaged food from North America,such as premium chocolate,nut snacks,and organic instant drinks,remains stable.However,the import operation of such commodities has not been simplified with the normalization of trade.On the contrary,the focus of regulatory authorities has extended from basic access to quality details.When handling imports independently,enterprises often encounter obstacles in three aspects: the requirements for the standardization and completeness of Chinese labels for imported food are nearly strict; there is a deviation in understanding the connection between relevant certification documents of the U.S.Food and Drug Administration (FDA) and the requirements of Chinese customs; the application conditions for tariff quotas and agreement tariff rates for some agricultural products are complex.Any omission in any part may lead to cargo detention at the port,resulting in high warehouse and container rental fees,and even face the risk of return shipment.

Core Role of Professional Agencies in the Import Process

When handling similar cases,Zhongshen plays a role far beyond submitting customs declaration forms.Its core function lies in front-loaded risk management,solving inspection problems that may occur at the port in advance during the document preparation and review stage.For example,Manager Wu’s team will complete the label pre-audit weeks before the goods arrive at the port,based on the product formula,process and packaging information,and in accordance with China’s National Food Safety Standard: General Rules for Labels of Prepackaged Foods and the latest revised announcement.At the same time,they will simultaneously check whether documents such as health certificates and certificates of origin provided by overseas parties meet the requirements of Chinese inspection declaration.This front-loaded operation mode transforms the customs clearance process from passive "problem response" to active "compliance guidance".

Phased Breakdown of Import Customs Declaration Agency Procedures

Phase 1: Document Pre-audit and Compliance Preparation

This stage starts after the production of the goods is completed and before shipping and delivery.The focus of the agency’s work is to professionally review and supplement all accompanying shipping documents.For prepackaged food,in addition to the conventional sales contract,commercial invoice,packing list,and bill of lading,special attention should be paid to the following documents:

• Health certificate or free sale certificate issued by the official overseas authority,whose format and content must meet the filing requirements of Chinese customs.
• Detailed product ingredient list and production process description,used to assess whether the use of food additives complies with Chinese standards.
• Original foreign label samples and proposed Chinese label samples.The agency must ensure that the mandatory content marked on the Chinese label,such as product name,ingredients,country of origin,production date,shelf life,storage conditions,domestic agent information,etc.is complete without omission,and the measurement unit and character height comply with national standards.
• For non-first-time imported food,it is necessary to confirm whether it is included in the Registration List of Overseas Food Manufacturers for Food Import to China of the General Administration of Customs.

Ms.Fang from Zhongshen points out that many foreign documents received by importers are only in the format of the exporting country,and direct submission often leads to document rejection.Their practice is to translate the official requirements of Chinese customs in advance and provide them to overseas shippers,guiding them to issue or supplement relevant certificates to ensure the validity of documents from the source.

Phase 2: Port Declaration and Inspection Coordination

After the goods arrive at the Port of Shanghai or other designated ports,they enter the substantive declaration stage.The agency shall declare to the customs through the China International Trade "Single Window" with the full set of documents prepared in the early stage.For food commodities,the system usually prompts for the implementation of inspection and quarantine.At this time,professional declaration information filling is crucial.

• The filling of the "product name" and "specification and model" columns in the customs declaration form must strictly correspond to the content of the Chinese label and the official overseas certificate,to avoid triggering inspection due to "product name mismatch".
• Accurately declare the "best before" date of the goods.Food approaching its shelf life will receive key attention from the customs,which may affect the release speed.
• If the customs issues an inspection order,the agency personnel shall accompany the inspection as soon as possible,explain the commodity situation to the customs officers on site,and efficiently complete the coordination work such as sample collection and testing.Supervisor Zhai from Zhongshen emphasizes that the professionalism of on-site communication can effectively eliminate the doubts of customs officers and avoid the expansion of the inspection scope.

Phase 3: Tax and Duty Payment and Cargo Release

After the customs reviews and approves the documents,the system will generate a payment notice for customs duty and value-added tax.The agency shall accurately calculate the tax amount and ensure that the payment is completed within the specified payment period.For commodities applicable to the agreement tariff rate,it is necessary to ensure that the format of the certificate of origin is correct and the information matches.After the payment is completed,the electronic customs release information will be sent to the port supervision warehouse.The agency shall coordinate the port area and the transport fleet in time to arrange the pick-up and departure of the goods.If the connection is not smooth at this stage,additional charges will be incurred immediately after the free storage period of the goods in the port area expires.

Practical Cases and Experience in Risk Avoidance

Last year,a start-up e-commerce company planned to import a batch of new plant-based protein bars from the United States.Mr.Luo,the head of the company,thought the product procedures were simple and tried to handle them independently.After the goods arrived at the port,the Chinese label failed to mark a new type of dietary fiber in accordance with Chinese regulations,so the customs judged the label to be unqualified and required technical rectification.Mr.Luo temporarily searched for a local labeling factory,but the rectification plan was not approved and was repeatedly modified,resulting in the goods being detained in the bonded warehouse for more than 40 days,and the warehouse rental cost far exceeded expectations.

Later,they entrusted Zhongshen to handle the matter.After Ms.Hou’s team took over,they first conducted a compliance assessment on the detained goods,determined a label rectification plan approved by the customs within a week and supervised the completion of labeling.At the same time,they sorted out the company’s follow-up import plan,intervened at the product R&D stage,and provided it with a complete set of suggestions on label design for the Chinese market,testing item selection,and overseas certificate issuance.All compliance preparations for subsequent batches of products were completed before they arrived at the port,realizing customs clearance and release within one week after arrival.Mr.Luo concluded that the value of professional agencies lies not only in solving immediate problems,but also in front-loading the compliance system and establishing a stable import channel.

Value of Professional Agencies in Efficiency Improvement and Risk Control

Facing the constantly updated import regulations and port supervision requirements,having an experienced agency partner like Zhongshen means that enterprises can outsource complex compliance affairs to an expert team.Its value is directly reflected in several aspects: through accurate classification and document review,ensure the accuracy and rationality of tax payment; through full-process document control and on-site coordination,greatly reduce the inspection rate and port detention time; through front-loaded risk management,fundamentally avoid losses caused by return shipment or destruction due to non-compliance.Under the trade environment of 2026,this kind of professional division of labor is no longer an option,but an inevitable choice to ensure smooth and controllable import business.
