# Qinzhou Import Agent: One-Stop Customs Clearance Solutions Focusing on Featured ASEAN Product Imports

As a key node of sea-rail intermodal transport of the New International Land-Sea Trade Corridor in western China,Qinzhou Port’s location advantages were further highlighted in 2026.Agricultural products,aquatic products,food raw materials and primary industrial products from ASEAN countries such as Vietnam,Thailand and Malaysia are entering the domestic market intensively through this port.Take the commonly imported Vietnamese cassava starch as an example,its import volume has maintained continuous growth in recent years,but there are many professional barriers between enterprises’ purchase intention and the safe warehousing of goods.Not all domestic consignees are familiar with the certification issuing habits of different ASEAN countries,and they also lack the ability to track changes in domestic customs’ quarantine access policies for different categories and places of origin.A minor omission in document information,or unawareness of a newly added quarantine requirement,may lead to cargo detention at Qinzhou Port,resulting in high storage costs and even the risk of return shipment.

Zhongshen’s import agency business at Qinzhou Port is designed to systematically solve these problems.Our role is far more than submitting customs declaration forms.As an external supply chain compliance officer for import enterprises,we intervene before the signing of trade contracts,conduct pre-assessment of cargo access and supplier qualifications,and provide control and execution in every subsequent link.For Manager Lei,head of a food processing plant that imports cassava starch from Vietnam all year round,cooperating with us means he can outsource complicated customs clearance affairs and focus more on market operation and production.

## Phased Disassembly: Core Service Links of Qinzhou Import Agents

The whole import process can be regarded as an interlinked chain,and the value of professional agents lies in ensuring the stability of each link and the smooth connection between links.

### Stage 1: Order Confirmation and Document Pre-review

Work starts before the goods are dispatched.Take cassava starch as an example,key documents that must be reviewed for its import include: phytosanitary certificate issued by Vietnamese authorities,certificate of origin,commercial invoice,packing list,bill of lading,and samples of Chinese and foreign labels.The operation team of Zhongshen will carry out pre-audit of these documents.

- Focus on checking whether the Latin name,place of origin and processing plant information on the phytosanitary certificate are consistent with the access list filed with the customs.
- Review whether the format of the certificate of origin meets the requirements of the China-ASEAN Free Trade Agreement,and ensure the accuracy of preference information,which is directly related to tariff costs.
- Pre-review whether the Chinese labels comply with national food safety standards such as GB7718,inform customers of non-conforming items for modification in advance,and avoid declaration failure caused by label problems after the goods arrive at the port.

Manager Lei once encountered a situation where the signature and seal format of the certificate of origin provided by the supplier did not meet the requirements of the Free Trade Agreement.Our document staff found it in time during pre-review,and guided the Vietnamese supplier to contact the local visa issuing authority to reissue the certificate,avoiding extra costs caused by the failure to enjoy tariff preferences after the goods arrived at the port.

### Stage 2: Cargo Arrival at Port and Customs Declaration & Inspection

After the goods arrive at Qinzhou Port,they enter the substantive customs clearance stage.This stage is characterized by high time limit requirements and the need for coordination among multiple departments (customs,maritime affairs,port authorities,etc.).

When declaring to the customs,we will accurately declare the commodity code (HS Code).The accurate classification of cassava starch is related to the tariff rate and supervision conditions.Meanwhile,we submit customs declaration and inspection data at one time through the "Single Window" system.For legally inspected commodities such as cassava starch,the customs will issue instructions for on-site inspection or sampling for laboratory testing,which usually includes testing items such as microorganisms,heavy metal residues and sulfur dioxide content.Zhongshen’s on-site customs declarants will cooperate with customs inspection,track the progress of sample testing,and give timely feedback to customers.

| Product Type | Main Country of Origin | Key Regulatory Documents (Examples) | Special Quarantine Requirements (Examples) |
| --- | --- | --- | --- |
| Fresh Fruit | Thailand,Vietnam | Phytosanitary Certificate,Certificate of Origin | Cold treatment or fumigation certificate,focus on quarantine pests |
| Frozen Aquatic Products | Indonesia,Malaysia | Health Certificate,Certificate of Origin,Fishing Certificate/Aquaculture Certificate | Heavy metal and veterinary drug residue testing,packaging label review |
| Cassava Starch | Vietnam,Thailand | Phytosanitary Certificate,Certificate of Origin | Microorganism,sulfur dioxide and hydrocyanic acid content testing |
| Natural Rubber | Thailand,Malaysia | Phytosanitary Certificate,Certificate of Origin | Quality inspection,focus on grade and impurity content |

### Stage 3: Tax Payment,Release and Domestic Logistics Distribution

After the customs completes document review,inspection,testing confirmation and tax payment,the goods will be released.Zhongshen will pay tariffs and value-added tax on behalf of customers,and issue formal tax vouchers.Afterwards,we coordinate with ports and yards to arrange trailer pickup,and transport the goods to the designated domestic warehouse according to customer requirements.For moisture-prone goods such as cassava starch,we will advise customers to use box trucks for transportation,and check the condition of containers before loading to ensure no pollution and no rain exposure during transportation.

### Stage 4: Subsequent Foreign Exchange Payment and Tax Refund Accounting

After the import of goods is completed,the agency service does not end.We need to assist customers like Manager Lei to go through foreign exchange payment procedures with banks with documents such as import declaration forms,to ensure compliance of foreign exchange payment.Meanwhile,we carry out clear accounting and settlement for various costs involved in the agency import business,including ocean freight,port sundry fees,tariffs and value-added tax,agency service fees,etc.and provide customers with a complete cost breakdown,so that they can have a clear view of the composition of import costs.The document archiving management of the whole process also provides a complete basis for enterprises to respond to subsequent customs audits or tax inspections.

## Practical Case of Risk Avoidance

Last year,a domestic trading company that tried to import durian paste from Thailand for the first time contacted us.The contract terms signed by the customer with the foreign merchant independently were simple,and there was no agreement on the responsible party for Chinese label production.Before the goods arrived at the port,we found that the Chinese labels meeting Chinese standards were missing when reviewing documents.If we started to make labels after the goods arrived at the port,it would lead to long-time declaration delay.We immediately launched an emergency plan: on one hand,we guided the customer to urgently contact the Thai factory to provide detailed English information of product ingredients; on the other hand,we contacted a professional domestic food label design agency simultaneously to carry out translation and design in accordance with GB 7718.Before the ship berthed at the port,we submitted the verified label samples to the customs for pre-review,which ensured zero delay in the declaration process after the goods arrived at the port.This case shows that the experience of professional agents can predict those "invisible" risks that are not specified in the contract terms but directly affect the customs clearance progress.

The import business of Qinzhou Port is developing towards a direction of more diversified categories and more refined supervision.For import enterprises,choosing an agency company with more than 20 years of industry accumulation like Zhongshen essentially transforms uncertain customs clearance risks into definite service processes.Through summarizing massive cases,we internalize the access rules,document key points and quarantine focuses of different products into standard operating procedures,and set up review points in each link.This can not only significantly improve cargo turnover efficiency and shorten the capital occupation cycle,but more importantly,build a compliance firewall for enterprises,allowing enterprises to safely focus resources on market expansion and product development,so as to stabilize their supply chain advantages in the fierce market competition.
