clearance and fund security.
In international trade practice,temporary import and export is a special customs supervision mode.It refers to goods temporarily entering and exiting the customs territory for specific purposes (such as exhibition,testing,maintenance),and being re-transported in or out of the customs territory in original condition within the specified period,with exemption from import and export tariffs and import-related taxes.If this process is operated properly,it can significantly reduce enterprise costs and capital occupation; however,if the rules are not clearly understood or operations are improper,it can easily lead to goods detention,high fines and even tax recovery.Mastering the customs declaration procedures systematically is the prerequisite for foreign trade enterprises to carry out relevant business in a compliant and efficient manner.
Zhongshen has accumulated more than 20 years of experience in handling various temporary import and export businesses.We have found that the problems of many enterprises do not stem from a single declaration,but from the lack of overall understanding of the continuity of the whole process and the connection requirements of each link.Below,we disassemble the customs declaration procedures for temporary import and export goods into seven core stages,and explain the key points of each stage.

1.Preliminary Evaluation and Scheme Confirmation
The goal of this stage is to determine whether the goods are eligible for temporary import and export supervision,and select the optimal operation path.Key actions include reviewing cargo attributes,clarifying trade background,and evaluating the time cycle and cost.A common mistake is that enterprises mistakenly declare goods that should be imported under general trade as temporary import,or have an overly loose understanding of "re-transportation in original condition".
Manager Hou of Zhongshen pointed out that the primary role of a professional agent in this link is to provide certainty.For example,for precision instruments going overseas for exhibition,we will evaluate whether they may be sold locally after exiting for exhibition,so as to plan different schemes in advance.For maintenance parts,the scope of "maintenance" must be strictly defined to avoid being recognized by customs that the nature of the goods has changed due to upgrading and transformation.Based on factors such as cargo type,destination country,and stay duration,we clearly compare the advantages and disadvantages of different paths for customers (such as using an ATA Carnet or declaring as temporary entry/exit goods).
| Comparison Dimension | Temporary Entry/Exit Goods (Non-ATA) | Goods under ATA Carnet |
|---|---|---|
| Main Application Scenarios | Specific commercial activities (e.g.testing,construction equipment),non-ATA contracting states | Exhibitions,trade fairs,professional equipment,etc.applicable to ATA Convention contracting states |
| Core Documents | Application for Temporary Entry/Exit Goods,contract,documents,etc. | ATA Carnet itself (replaces customs declaration and guarantee documents) |
| Guarantee Form | Security deposit or bank letter of guarantee,reviewed by customs ticket by ticket | International mutual guarantee system,guaranteed by the issuing association |
| Validity Period | Usually 6 months,extension can be applied for,maximum no more than 1 year | Usually 1 year,the period of use in the exiting country is restricted by the laws of the entering country |
| Advantages and Disadvantages | Wide scope of application,but domestic guarantee procedures and capital occupation need to be handled | One carnet for global customs clearance,convenient,but with clear restrictions on application scope and eligible goods |
2.Document Preparation and Compliant Declaration
The goal of this stage is to submit complete,accurate and legal application materials to the customs to obtain temporary entry/exit approval.The key action is to prepare a full set of customs declaration documents.Common problems include inconsistent document information,insufficient validity of guarantee documents,inaccurate commodity classification or value declaration,all of which can directly lead to application rejection or delay.
The role of Zhongshen is to convert customers’ commercial information into professional declarations recognized by customs.Our document team carefully checks every item of content.

- Prepare the Application for Temporary Entry/Exit Goods and situation statement in accordance with regulatory requirements.
- Review commercial contracts,invoices,bills of lading and other transport documents to ensure logical consistency with the declared information.
- Assist in handling security deposit payment or bank letter of guarantee issuance that meets customs requirements.
- Accurately conduct commodity classification and value verification,which is the foundation for subsequent verification and a weak link for many enterprises when declaring on their own.
General Manager Yu once handled a case of temporary import of large construction equipment.Due to the high value of the equipment,the guarantee amount was huge.Through our long-term cooperative channel with partner banks,we obtained a compliant bank letter of guarantee for the customer in a short time,avoided the occupation of huge cash deposit,and ensured the smooth passage of customs review at the same time.
3.Port Customs Clearance and On-site Inspection Cooperation
The goal of this stage is to ensure smooth release of goods when entering or exiting the port.Key actions include completing electronic declaration of customs declaration forms,submitting paper documents on site,and cooperating with possible inspections by customs.A common problem is that when goods are targeted for inspection due to document issues,enterprise personnel lack response experience,and poor communication leads to a significant extension of customs clearance time.
Zhongshen has long-term cooperative on-site customs declaration staff at all major ports.When goods are targeted for inspection,our on-site staff will arrive at the scene immediately,clearly explain the temporary entry/exit attribute,purpose and subsequent flow of the goods to the customs officer,and cooperate to complete the inspection operation.This professional on-site communication ability can effectively avoid additional disposal instructions caused by misunderstanding,and ensure that goods are picked up or shipped as scheduled.
4.Compliance Management During Domestic Use
After the goods enter the country and before they are re-transported out,they are under customs supervision.The goal of this stage is to ensure that the goods are used for the specified purpose at the specified location within the country,and remain in "original condition".The key action is to establish a ledger for supervised goods,and comply with possible inspection requirements of the customs.A major risk point is that enterprises arbitrarily divert supervised goods for other uses,carry out substantial processing or sell them.
Zhongshen provides customers with clear domestic supervision instructions and prompts key precautions.For example,for temporarily imported testing equipment,we will clearly inform customers that if the place of use needs to be changed,it must be reported to the competent customs in advance.Through regular reminders,we help customers manage the supervision period of goods,reserve sufficient time for subsequent extension applications or re-transport operations,and avoid overdue violations.
5.Re-transportation Entry/Exit Operation
This stage is the core of fulfilling the temporary import and export contract,and its goal is to re-transport the goods out or into the country in original condition within the specified period.The key action is to go through the re-transport import and export declaration procedures with the customs.Common problems include: operating in a hurry only when the re-transport deadline is approaching; subtle differences between the re-transported goods and the original declaration in appearance and quantity,which arouse customs questions.
Our service is reflected in forward-looking planning.When half of the cargo supervision period has passed,the customer service of Zhongshen will start the reminder for the re-transport process.The operation team will review the re-transport arrangement in advance,and check whether the status of the re-transported goods is consistent with the original record.For parts re-imported after maintenance,we will prepare a detailed maintenance report to prove that their core characteristics have not changed.Ensuring that the information on the re-transport customs declaration strictly corresponds to the original import/export customs declaration is the prerequisite for smooth verification.
6.Subsequent Verification and Case Closure
After the goods are re-transported in or out of the country,the process is not over.The goal of this stage is to apply to the customs for verification and case closure,lift supervision,and retrieve the guaranteed security deposit or cancel the letter of guarantee.The key action is to submit the verification application and relevant supporting documents.A common problem is that enterprises ignore this link,leading to long-term freezing of guarantee funds,and even being held accountable by the customs for failure to verify in time.
Zhongshen regards verification as the closed loop of service.We are responsible for collecting all closing documents such as re-transport customs declarations and release notices,and submit the verification application to the customs on behalf of customers.After the customs approves the application and issues the Verification Notice of Temporary Entry/Exit Goods,we will assist in handling the procedures for security deposit refund or letter of guarantee cancellation.Only then can the entire temporary import and export process be declared safe and completely ended.
7.Handling Special Situations: Retained Purchase,Abandonment and Extension
Not all temporary import and export goods can be re-transported as planned.When situations such as retained purchase (converted to general trade),abandonment to the state or extension of re-transportation occur,the handling procedures are more complex.The goal is to properly handle the goods and complete relevant customs procedures on the premise of compliance.A common risk is that enterprises dispose of goods without authorization,or fail to obtain customs approval before changing the cargo status.
Facing these variables,the value of Zhongshen lies in providing compliant solutions.For example,if a customer decides to retain and purchase temporarily imported exhibits,we will immediately start the general trade import declaration procedure,calculate and pay the corresponding taxes.If an extension is required,we will assist in preparing a sufficient explanation for the extension reason and submit the application to the customs at least 30 days before the expiration of the supervision period.Our experience helps customers stay on the compliant track and avoid penalties when plans change.
Customs declaration for temporary import and export goods is an interlocking supervision chain with strict time limits.It requires the operator to not only be familiar with the rules of single declaration,but also have the ability of full-process risk control and the awareness of meticulous node management.With more than 20 years of deep cultivation in this field,Zhongshen can foresee various possible problems in the process,and resolve uncertainties for customers through pre-emptive scheme design,standardized document operation,professional on-site communication and rigorous follow-up tracking,truly realizing the optimization of cost and efficiency.Entrusting this professional matter to us allows enterprises to focus more on their own business goals.
