Detailed Explanation and Practical Guide to Import Inspection Agency Procedures in Chengdu

In 2026,as a highland of opening-up in western inland China,Chengdu continues to see rising activity in import trade,especially the significant growth in the volume of high value-added food and mechanical equipment imported from Europe,Southeast Asia and other regions.However,for many enterprises with little or no prior experience,delivering goods to Chengdu Port is only the first step,and the complicated import inspection process often becomes a "stumbling block" hindering the rapid launch of goods to the market.Especially for specific products such as pre-packaged food or precision instruments,Chengdu Customs implements extremely strict standards in inspection and quarantine,label review and compliance inspection.Problems such as inconsistent documents,missing label information or quarantine risks can easily lead to cargo detention at the port,incur high container detention fees and storage fees,and even face severe consequences of return or destruction.

Against this background,the import agency services provided by Zhongshen are particularly critical.We are not just simple declaration operators,but also "gatekeepers" for enterprises’ compliant imports.In response to the special regulatory requirements of Chengdu Port,Zhongshen leverages more than 20 years of deep industry experience to advance our services and intervene before goods depart.Through professional document pre-review and risk assessment,we eliminate potential compliance issues at the source.We are familiar with the differentiated operation procedures of Chengdu Shuangliu Airport Port and Qingbaijiang Railway Port,and can develop the most optimized import inspection plan based on cargo characteristics and logistics routes,ensuring "second-level" clearance when goods enter Chengdu’s customs territory.

Document Pre-review and Compliance Confirmation

The first step of import inspection does not start at the port site,but in the document preparation stage before cargo shipment.For specific products imported from target countries,official certificate of origin,health certificate,composition analysis report and inspection report are indispensable basic documents.Under the 2026 regulatory environment,Chengdu Customs has fully implemented electronic data comparison for document review.Any minor information error,such as logical contradiction in certificate date,mismatched product name and code,will trigger a system warning and lead to manual document review.

The core role of Zhongshen at this stage is to conduct strict document pre-review.We will check the documents provided by overseas suppliers one by one against Chinese national standards and the latest announcements of the General Administration of Customs of China.For example,when processing a shipment of pre-packaged food imported from Germany,we will focus on checking whether the issue date on the certificate of origin is earlier than the shipment date,and whether the name of the manufacturing enterprise on the health certificate is registered with the General Administration of Customs.Once information inconsistency is found,we will immediately guide the enterprise to communicate with overseas suppliers for rectification,avoiding the situation that goods cannot be declared due to document problems after arrival at the port.

Label Review and Rectification Service

For imported food,the Chinese label is the top priority of the import inspection process,and it is also a high-frequency inspection item at Chengdu Port.According to the General Standard for the Labeling of Prepackaged Foods and the latest revised clauses implemented in 2026,the label must include mandatory contents such as food name,ingredient list,net content,producer information,shelf life,storage conditions and nutrition information table.

Zhongshen has a professional label review team that can conduct full-dimensional compliance checks on the Chinese label drafts provided by customers.We will pay special attention to whether the calculation method of the nutrition information table meets Chinese standards,whether the warning statement is eye-catching,and whether the font height meets the requirements.If any defect is found in the label during the review,we will provide specific modification suggestions and assist the enterprise to contact the overseas factory for labeling or rectification,ensuring that the label is in "perfect condition" before the goods arrive at Chengdu Port,so that it can pass the on-site inspection smoothly.

Port Customs Declaration and Import Inspection Declaration

After the goods arrive at Chengdu Port,the formal customs declaration and import inspection process starts immediately.In 2026,Chengdu Customs has fully promoted the "two-step declaration" and "advance declaration" modes,which put forward higher requirements for the accuracy and completeness of declaration data.At this stage,enterprises need to accurately fill in key information such as HS Code,specification and model,country of origin,and trade mode through the single window.

The operation team of Zhongshen has strong data sensitivity.During the declaration process,we will accurately classify the HS code according to the physical properties and use of the product,ensuring the correct application of tax rates and regulatory conditions.For goods subject to legal inspection,we will initiate customs declaration and import inspection instructions simultaneously,and use the "one-time declaration" system to achieve seamless data connection.Our operators are well aware of the inspection deployment rules of Chengdu Customs District for specific high-risk commodities,and will fill in the element fields in a particularly standardized manner during declaration,reducing the probability of inspection triggered by random system deployment,and saving valuable customs clearance time for enterprises.

Differentiated Operation Response for Chengdu Port

Chengdu mainly conducts import operations through Shuangliu International Airport and Qingbaijiang Railway Port.Zhongshen has a deep understanding of the operation characteristics of these two ports.Shuangliu Airport Port focuses on urgent air cargo,which has extremely high requirements for customs clearance efficiency,so we will prioritize the "advance declaration,clearance upon arrival" mode; while Qingbaijiang Railway Port,as a distribution center for China-Europe Railway Express,has more strict inspection procedures for bulk cargo and full container cargo,we will coordinate the inspection site in advance and arrange devanning and transfer plans properly.

In actual operations,we have encountered abnormal inspection status caused by system data transmission delay.With the close cooperation mechanism with local customs and customs brokers,Zhongshen can quickly troubleshoot the cause of the problem,and restore the declaration process in the shortest time through manual intervention or resending the message,avoiding customs clearance delay caused by technical failures.

On-site Inspection and Sampling Testing

Even if the declaration is successful,the goods may still face on-site inspection or sampling for testing by the customs.This is the most uncontrollable link in import inspection.For food,inspectors will check whether the actual information of the goods is consistent with the declared label,check whether the packaging is intact,and whether there are signs of moisture or contamination.For testing,customs will draw samples according to risk control instructions and send them to the laboratory to test indicators of microorganisms,heavy metals or additives.

At this stage,Zhongshen is not only a cooperator but also a coordinator.Once the inspection notice is received,our on-site field staff will rush to the inspection site with the necessary documents as soon as possible.During the inspection,we can accurately answer the customs officer’s questions about the product’s attributes,composition and use,and eliminate the customs officer’s doubts.If sampling for testing is required,we will assist the customs officer in standardized sampling and send the samples to the designated laboratory as soon as possible.At the same time,we will track the testing progress in real time.Once abnormal test results are found,we will immediately activate the emergency plan,assist the enterprise in technical analysis or apply for re-inspection,and make every effort to salvage the goods.

Practical Case of Compliance Risk Avoidance

Last year,Mr.Deng,a local food trader in Chengdu,planned to import a batch of high-end olive oil from Italy.Since it was his first time handling this type of product,he was not sure about the ingredient translation standards for Chinese labels,and the health certificate format provided by the overseas supplier was outdated.After the goods arrived at Shuangliu Airport,they were indeed targeted for inspection by customs.

Since Zhongshen intervened in document pre-review in advance,we had already identified the potential risk in the health certificate format and guided the supplier to add a supplementary statement that complies with the 2026 new regulations in advance.At the inspection site,when the customs officer pointed out that the labeling position of "acidity" was non-standard,we took out the pre-prepared rectification plan and the label explanation approved by customs on site,and explained in detail the corresponding relationship between the international standard and domestic standard of this product to the customs officer.Finally,the customs officer accepted our explanation,only issued a minor rectification order for the label,and did not require sampling for testing.The goods were cleared smoothly on the same day.Mr.Deng later said that without Zhongshen’s professional prediction and on-site response,this batch of goods would have been delayed for at least a week and faced high storage costs.

To more intuitively demonstrate the value of a professional agency in import inspection,we can compare the differences between enterprise self-handled import and import entrusted to Zhongshen:

Conclusion

Under the increasingly stringent trade regulatory environment in 2026,import inspection in Chengdu is no longer a simple form-filling and declaration process,but a systematic project involving laws and regulations,commodity knowledge,customs clearance skills and on-site coordination capabilities.With 20 years of industry accumulation,Zhongshen has built a solid firewall for importing enterprises.From the preliminary document compliance sorting,to the efficient implementation of declaration in the middle stage,and to the emergency handling of inspection in the later stage,we have achieved full-process professional control,which not only greatly improves import efficiency,but also minimizes the compliance risk of enterprises.Choosing Zhongshen means choosing a safe,efficient and worry-free import channel,allowing enterprises to focus on market sales without any worries.
