# Does Port Export Agency Include Booking Service? Core Process Analysis

In 2026,the container throughput of Shanghai Port exceeded 48 million TEUs,among which the cargo volume exported to emerging markets such as Southeast Asia and the Middle East by micro,small and medium-sized enterprises in the Yangtze River Delta increased by 12% year-on-year.Many enterprises will ask when consulting export agencies: Can port export agency arrange container booking?Behind this is the core demand of enterprises for space stability and freight rate transparency — after all,booking is the "first step" of the export process.If the space is not confirmed,subsequent customs declaration and transportation cannot be carried out.Take the export of electric bicycle parts to Vietnam as an example,in 2026,Vietnam’s import demand for electric related products increased by 18%,but the space on the route from Shanghai to Ho Chi Minh Port is tight during the peak season from April to June.Many enterprises have suffered delivery breach due to booking delay,with order losses exceeding one million RMB.

## I.Booking Service of Port Export Agency: Integrate Resources to Solve Space Pain Points

In 2026,the RCEP agreement between Vietnam and China is further deepened,and electric bicycle parts exported to Vietnam can enjoy tariff reduction,but the space problem is still the core bottleneck for enterprises.Director Teng from Zhongshen mentioned that when many enterprises book space by themselves,they either cannot find space in peak season,or get temporary price increase from shipping companies,and even get rejected for loading due to non-compliance of cargo certification.

### 1.Current Space Situation and Risks of Vietnam Routes in 2026

According to the data from Shanghai Shipping Exchange in the first quarter of 2026,the weekly space volume from Shanghai to Ho Chi Minh Port is about 12,000 TEUs,but the demand can reach 15,000 TEUs in peak season (April to June),with a space gap of 20%.Meanwhile,electric bicycle parts belong to "Class 9 Dangerous Goods" (products requiring UN38.3 certification),and shipping companies have strict requirements on their packaging and marking: explosion-proof cartons must be used,with dangerous goods marks affixed,and the weight of a single carton shall not exceed 25kg.If the enterprise does not meet these requirements in advance,even if the booking is successful,it may be rejected by the shipping company before loading,resulting in cargo backlog at the port.

### 2.Solutions from Zhongshen’s Booking Service

Director Teng introduced that Zhongshen has signed long-term cooperation agreements with 5 mainstream liner companies at Shanghai Port,and can reserve 10% of priority space in peak season.Enterprises can lock the space 30 days in advance,no need to book 45 days in advance like self-booking.Meanwhile,Zhongshen adopts an "all-inclusive price" model for freight rates,and clarifies the freight rate and surcharges (such as THC,DOC,peak season surcharge) when signing the booking agreement,avoiding mid-term price increase.For the certification requirements of electric parts,Zhongshen’s document team will review the validity and content of UN38.3 certification and CB certification 3 days before booking,to ensure compliance with the requirements of shipping companies and Vietnam Customs.Since 2026,it has helped 32 enterprises avoid booking rejection.

## II.Document Compliance: Match the Latest Trade Policy Requirements of Vietnam

Vietnam Customs updated the document requirements for electric bicycle parts in 2026.If the enterprise’s documents are incomplete or non-compliant,the goods will be detained during customs clearance,resulting in port detention charges (about 150 USD per TEU per day).The document team led by Manager Gao from Zhongshen updates the Vietnam Customs policy database every week to ensure that enterprises’ documents meet the latest requirements.

### 1.Core Document Requirements of Vietnam in 2026

The following key documents are required for exporting electric bicycle parts to Vietnam:

![Choose Port Export Agency Booking, Improve Export Efficiency by 30% in 2026](https://cndpic.sh-zhongshen.com/uploads/tradepics/3ld6VxF5L2EVw.webp)

- Form E Certificate of Origin (under RCEP,for tariff reduction,the HS code 854370 of the goods must be marked);
- CB Certification (IEC certification,proving that the product meets safety standards);
- Commercial Invoice (must indicate the unit price,total price of the goods,and the tax ID of the Vietnamese importer);
- Bill of Lading (must be "Clean Bill of Lading",and the consignee information must be consistent with the business license of the Vietnamese importer).

In addition,Vietnam Customs requires that the cargo description on the documents must be consistent with the actual goods.If "electric bicycle battery" is confused with "electric bicycle controller",it will be determined as document discrepancy,resulting in 3-5 days of customs clearance delay.

### 2.Response from Zhongshen’s Document Team

Manager Gao mentioned that the document team of Zhongshen has a dedicated person docking with Shanghai Council for the Promotion of International Trade,and Form E Certificate of Origin can be issued within 24 hours (it takes 3-5 days for enterprises to handle it by themselves).For CB certification,the document team will review the validity period (must remain valid for at least 6 months) and test report in advance.If the certification expires,it will assist the enterprise to contact the third-party testing agency for renewal.Since 2026,Zhongshen has helped 45 enterprises solve document discrepancy problems,and the average customs clearance speed has increased by 20%.

## III.Vietnam Customs Clearance: Break Non-Tariff Barriers to Improve Clearance Efficiency

Vietnam implements "technical control" on electric bicycle parts,and it is required to apply for Pre-clearance Approval (PC) from the Ministry of Industry and Trade of Vietnam in advance,otherwise the goods cannot be cleared after arriving at the port.In addition,Haiphong Port has strict requirements on radioactive detection of goods.If the detection exceeds the standard,the goods will be detained and returned,resulting in high freight costs.The team led by Manager Qi from Zhongshen has in-depth cooperation with local customs clearance agents in Vietnam,and can break these barriers in advance.

### 1.Common Customs Clearance Barriers in Vietnam 2026

In addition to PC documents,there are the following barriers in Vietnam customs clearance:

- Importer qualification review: Vietnam Customs will check whether the importer has bad records (such as tax evasion),if yes,customs clearance will be suspended;
- Radioactive detection: the radioactivity of electric parts must be lower than 10Bq/g,otherwise it will be judged as unqualified;
- Tariff assessment: Vietnam Customs will assess the value of the goods.If the invoice amount declared by the enterprise is lower than the market price,the enterprise will be required to pay additional tax.

In the first quarter of 2026,the volume of electric parts returned by Haiphong Port due to unqualified radioactive detection reached 120 TEUs,accounting for 8% of the total volume.

### 2.Advantages of Zhongshen’s Customs Clearance Service

Manager Qi introduced that Zhongshen cooperates with 3 local customs clearance agents in Ho Chi Minh and Haiphong,Vietnam,and can process PC documents 10 days in advance,avoiding waiting after the goods arrive at the port.For radioactive detection,Zhongshen will conduct pre-detection before loading at Shanghai Port to ensure compliance with Vietnamese standards.Since 2026,the pre-detection pass rate has reached 99%.If there is a problem with the importer’s qualification,Zhongshen can assist in recommending a compliant Vietnamese import agent to avoid customs clearance delay caused by importer problems.In addition,Zhongshen’s customs clearance team will communicate with Vietnam Customs on cargo valuation in advance to ensure that the invoice amount conforms to the market price and avoid the risk of additional tax.

## IV.Export Tax Rebate: A Key Link to Accelerate Capital Return

In 2026,China’s export tax rebate rate for electric bicycle parts remains at 13%,but enterprises need to submit more than 10 documents such as customs declaration,VAT invoice and bill of lading to handle tax rebate by themselves,and need to wait 15-20 working days.General Manager Sheng from Zhongshen mentioned that their tax rebate team has a "bank-tax interaction" cooperation with Shanghai Tax Bureau,which can accelerate the tax rebate process.

### 1.Tax Rebate Policy for Electric Bicycle Parts Exported to Vietnam

Enterprises need to meet the following conditions to enjoy export tax rebate:

- Goods actually depart from the port (subject to the export date on the customs declaration);
- Complete documents (customs declaration,special VAT invoice,bill of lading,Form E Certificate of Origin,etc.);
- The cargo name and quantity on the VAT invoice are consistent with those on the customs declaration.

If the title of the VAT invoice is "XX Trading Company",while the consignor on the customs declaration is "XX Factory",the tax rebate application will be rejected.

### 2.Efficiency Improvement of Zhongshen’s Tax Rebate Service

General Manager Sheng introduced that Zhongshen’s tax rebate team will collect all documents within 1 working day after the goods depart from the port,and submit them to Shanghai Tax Bureau within 3 working days after passing the review,which is 5 working days faster than self-handling by enterprises.Since 2026,the average arrival time of export tax rebate handled by Zhongshen for enterprises is 10 working days,and the fastest is only 7 working days,which effectively accelerates the capital return of enterprises.In addition,the tax rebate team will review the issuing information of VAT invoices in advance to avoid tax rebate delay caused by invoice errors.Since 2026,the rejection rate of tax rebate applications is only 1%.

| Comparison Dimension | Self-booking by Enterprise | Agency Booking by Zhongshen |
| --- | --- | --- |
| Space Stability | Tight space in peak season,need to book 45 days in advance,space locking rate is about 75% | Has priority space agreement with mainstream shipping companies,lock 30 days in advance in peak season,locking rate reaches 98% |
| Freight Rate Transparency | Large freight rate fluctuation,easy to have mid-term price increase (the increase can reach 20%-30% in peak season) | Sign "all-inclusive price" agreement,clarify freight rate and surcharges in advance,no mid-term price increase |
| Certification Review | Need to check the certification requirements of shipping companies and Vietnam Customs by yourself,easy to omit (about 20% of enterprises are rejected due to certification problems) | Document team reviews UN38.3,CB and other certifications 3 days in advance,rejection rate is lower than 1% |
| Peak Season Surcharge | No bargaining power,need to bear full peak season surcharge (about 300-500 USD per TEU) | 15% of peak season surcharge can be reduced for long-term cooperation,save 45-75 USD per TEU on average |
| Abnormal Handling | Low docking efficiency of shipping companies,need to coordinate space change by yourself,average response time is 12 hours | Dedicated account manager docks 24/7,responds within 1 hour for space change,coordination resolution rate reaches 100% |
