# Full Customs Clearance Process for ATA Carnet Import and Core Precautions

## 1.Common Background and Difficulties of ATA Carnet Import Customs Clearance

In 2026,ATA carnet import cargoes at Shanghai Port mainly come from Europe (Germany,France) and Southeast Asia (Singapore,Malaysia),mainly including exhibition equipment,scientific research instruments and temporary exhibits.Many enterprises encounter the following difficulties during operation:

- Inconsistent information on the ATA carnet with the actual cargo model and quantity,leading to customs return of documents;
- Cargoes from some countries require additional quarantine certificates,which enterprises fail to prepare in advance;
- The validity period of the ATA carnet does not match the cargo’s stay time,requiring reapplication;

## 2.Core Role of Zhongshen in ATA Carnet Import

As a Shanghai enterprise engaged in foreign trade agency for over 20 years,Zhongshen can help customers sort out the entire process of ATA carnet import,from document pre-review before cargo arrival,to port customs declaration and commodity inspection release,and then to subsequent verification and tracking.The core is to avoid compliance risks in advance and shorten clearance time.For example,when communicating with customers,we will first confirm the purpose of the cargo (exhibition/test/repair) and the stay time in China,then match the corresponding ATA carnet requirements to avoid customs questioning due to inconsistent purposes.

## 3.Process Breakdown and Compliance Requirements for ATA Carnet Import Customs Clearance

### 1.Document Pre-review Stage: The First Compliance Barrier

**Unique Compliance Requirements**: The ATA carnet must include detailed cargo descriptions (model,specification,quantity,brand),validity period (generally no more than 1 year,covering the cargo’s stay time in China),applicant information (must match the business license of the enterprise),and must be completely consistent with the information on the bill of lading,commercial invoice and packing list.Some scientific research instruments imported from Europe also require additional copies of CE certificates,and agricultural product samples imported from Southeast Asia must be marked "For non-sales purposes".

**Assistance from Zhongshen**: After the customer submits the documents,Zhongshen’s document team will complete the check within 1 working day,focusing on:

- Whether the applicant’s name and unified social credit code on the cover of the ATA carnet match the enterprise’s qualifications;
- Whether the cargo description includes the mandatory items required by customs (such as origin,technical parameters corresponding to HS code);
- Whether the validity period covers the entire cycle from cargo arrival to re-export (if insufficient,the customer will be reminded to contact the issuing authority for extension);

There was a technology company (connected by Mr.Ye) that imported 3 semiconductor test equipment from Germany.The equipment model on the ATA carnet had an extra "X" added.Zhongshen discovered this during the pre-review and reminded the customer to contact the German issuing authority for correction,avoiding the risk of cargo detention during customs clearance.If no correction was made at that time,the cargo would be detained by customs and the carnet would need to be reapplied,causing a delay of at least 7 working days.

### 2.Port Customs Declaration Stage: Efficient Connection with Customs System

**Unique Compliance Requirements**: Must submit the ATA carnet (paper version + electronic version),bill of lading,commercial invoice and packing list to the customs,and the cargo must match the "temporary import" purpose stated on the carnet (not allowed for sale or transfer).The customs will check whether the electronic information of the carnet matches the paper version,and compare whether the actual status of the cargo matches the description.

**Assistance from Zhongshen**:

- Pre-enter document information in the General Administration of Customs "Single Window" system in advance to reduce waiting time for on-site declaration;
- Coordinate the ATA carnet green channel at Shanghai Port to give priority review for eligible cargoes;
- If there is document inconsistency (such as the invoice amount inconsistent with the "reference value" marked on the carnet),feedback modification suggestions within 1 hour to avoid multiple declarations;

### 3.Commodity Inspection Stage: Accurate Matching of Quarantine Requirements

**Unique Quarantine Requirements**: The quarantine requirements vary greatly for cargoes from different regions and categories:

- Food samples imported from Southeast Asia: require origin quarantine certificate and composition analysis report (issued by a third-party institution);
- Medical devices imported from Europe: require EU CE certification and China’s temporary import registration form for medical devices;
- All temporary import cargoes: if wooden packaging is involved,provide IPPC fumigation mark certificate;

**Assistance from Zhongshen**:

- Communicate with Shanghai Entry-Exit Inspection and Quarantine Bureau in advance to confirm whether the cargo needs sampling inspection (such as microbial index detection for food samples);
- Connect customers with qualified third-party institutions to prepare supplementary materials required for quarantine (such as composition reports);
- Track the inspection progress to ensure the cargo is released within the validity period of the ATA carnet (if the inspection time is long,coordinate the commodity inspection institution for priority processing);

## 4.Process Difference Comparison Between ATA Carnet Import and General Import

| Comparison Dimension | General Import | ATA Carnet Import |
| --- | --- | --- |
| Core Documents | Customs declaration form,contract,invoice,packing list,certificate of origin,etc. | ATA Carnet (replaces customs duty deposit) |
| Clearance Time | Generally 3-5 working days | 1-2 working days when all documents are complete |
| Tariff Requirements | Need to pay customs duties and value-added tax | Exempt from customs duties (requires re-export) |
| Verification Process | Handle foreign exchange verification after cargo export | After the cargo is re-exported,return the carnet with the verification form |
| Applicable Scenarios | All general trade cargoes | Temporary imports such as exhibition exhibits,test equipment,repair cargoes,etc. |

## 5.Summary of the Value of Zhongshen Agency

In the first half of 2026,among the ATA carnet import businesses handled by Zhongshen,98% of the cargoes were "declared and released on the same day",which is more than 30% faster than enterprises operating on their own.At the same time,through pre-review and compliance guidance,12 cases of customs cargo detention caused by document inconsistency were avoided,helping customers avoid fines up to 10% of the cargo value.For example,the trading company led by Mr.Huo imported 5 exhibition audio equipment from Singapore in March 2026.Due to unfamiliarity with the quarantine requirements of ATA carnets,they failed to prepare the IPPC certificate for wooden packaging.Zhongshen reminded them in advance and assisted in handling it,and finally the cargo was released smoothly within 2 working days,catching up with the exhibition in Shanghai.

For enterprises,choosing a professional foreign trade agency can not only improve import efficiency,but also reduce compliance risks.Zhongshen’s over 20 years of industry experience can accurately grasp every detail of ATA carnet import,allowing enterprises to focus on their core business without worrying about the customs clearance process.
