# Longgang Enterprise Maritime Import and Export Agency Full Process Analysis and Key Node Control Guide

## Understanding the Complexity of Longgang Enterprises’ Maritime Import and Export Business Chain

In 2026,the annual export value of industrial clusters such as integrated circuits and new energy equipment in Longgang District exceeded 500 billion yuan,and the maritime container throughput accounted for nearly 40% of the total throughput of Shenzhen Port.The enterprise where Manager Lei works has just completed an order of precision equipment shipped to the Netherlands.He found that from workshop packing to foreign exchange receipt,the process involves the connection of 16 departments,the circulation of more than 30 documents,and more than 10 variables such as exchange rate,shipping space,and inspection rate.Any deviation in any link may lead to the detention of the whole batch of goods at the port or a delay of half a year in the receipt of tax refund.This complexity determines that handing over links such as customs declaration,transportation,foreign exchange settlement and tax refund to professional agencies for overall coordination is no longer a simple cost consideration,but a strategic choice for supply chain stability.

## Phase 1: Compliance Preparation and Document Production Before Goods Shipment

Manager Lei’s experience shows that 80% of the root causes of maritime export problems lie in the preparation stage before loading.The core goal of this stage is to ensure that the declared information of the goods is completely consistent with the actual situation and meets the access standards of the destination country.

### Key Action Breakdown

- Commodity classification confirmation: Pre-classify complex commodities such as precision instruments and lithium batteries in accordance with the latest 2026 edition of the Import and Export Tariff,to avoid subsequent classification disputes with customs
- Trade clause review: Review the division of responsibilities under clauses such as CIF and FOB,clarify the parties responsible for insurance and freight,and prevent freight forwarding fee disputes
- Document matrix production: Prepare core documents such as invoices,packing lists,customs declaration forms,certificates of origin,and transport appraisal reports simultaneously to ensure data consistency from the same source
- License pre-judgment: For dual-use items and statutory inspection commodities,apply for export licenses or electronic ledgers in advance

Common problems are concentrated in document return caused by classification errors and inspection caused by inconsistent documents.Zhongshen assigns customs officers to conduct on-site pre-inspection at the factory in this link,and implements the "three-review mechanism" for each batch of goods of Manager Lei’s enterprise.In the first quarter of 2026,this mechanism helped Longgang clients avoid 12 classification risks,and the average customs clearance time was shortened by 2.3 working days.

## Phase 2: Customs Declaration,Inspection and Port Operation Coordination

After the goods arrive at Yantian Port or Shekou Port,they enter the most critical port operation period.The goal of this stage is to complete all statutory procedures before the customs cutoff time to ensure the smooth loading of the goods.

### Port Operation Timeline

- Customs declaration: Complete electronic declaration 4 hours before the goods arrive at the port,and trigger risk analysis in advance by using the Shanghai-Shenzhen customs data synchronization system
- Inspection connection: For statutory inspection commodities,push the electronic ledger to the inspection and quarantine system simultaneously to realize "one declaration" for customs declaration and inspection
- Port coordination: Connect with the terminal operation department in real time to obtain dynamic information of stowage plan,gate status and yard location
- Abnormality handling: In case of customs inspection instructions,coordinate the inspection site and personnel within 30 minutes to avoid container lifting fees

After Shenzhen Port implemented full coverage of "intelligent image inspection" in 2026,the machine inspection rate increased to 65%.Zhongshen pre-adjusts the declaration elements by rehearsing the X-ray imaging characteristics of the goods,reducing the inspection rate of Manager Lei’s enterprise from the industry average of 8% to 2.1%,directly reducing the inspection container lifting fee and demurrage cost of about 800 yuan per container.

## Phase 3: Maritime Booking and In-transit Risk Control

The ability to obtain shipping space and the transparency of the transportation process directly affect the reliability of delivery commitments.In 2026,the situation in the Red Sea continues to affect the freight rates of European routes,and the aftermath of labor-management negotiations at US West Coast terminals has not subsided,exacerbating market uncertainty.

### Booking Strategy and Implementation

- Annual contract lock-in: Sign annual freight rate agreements with members of the three major shipping alliances to ensure priority of shipping space in peak seasons
- Dynamic freight rate monitoring: Capture spot market freight rates through API interface,and launch spot booking when the contract price is 15% higher than the market price
- Ship schedule stability assessment: Based on historical on-time rate data,priority is given to routes with fewer calling ports and low delay rate
- In-transit visibility system: Provide container GPS positioning,ship AIS trajectory,and estimated arrival time deviation warning

In response to the widespread "space explosion and container rolling" phenomenon in 2026,Zhongshen has set up a shipping space guarantee mechanism for Longgang clients.An urgent order of Manager Lei was temporarily notified of container rolling by the shipping company during the peak season in April 2026,and Zhongshen coordinated spare shipping space of other shipping companies on the same route within 6 hours,avoiding the risk of production line shutdown.

## Phase 4: Foreign Exchange Receipt and Payment and Export Tax Refund Completion

The loading of goods is only the beginning,and the safe receipt of foreign exchange and the return of tax refund are the signs of the closed loop of export.In 2026,the State Administration of Foreign Exchange implemented the new regulation of "macro-prudential management of cross-border capital flow",and the monitoring of abnormal foreign exchange transactions is more stringent.

### Key Nodes of Capital Flow

- Foreign exchange declaration: Submit foreign exchange income declaration through China Electronic Port within 24 hours after the customs declaration form is released,and match the customs declaration number with the foreign exchange receipt memo
- Foreign exchange settlement timing selection: Based on the US dollar index and RMB exchange rate fluctuation model,provide batch foreign exchange settlement suggestions to avoid exchange rate losses
- Tax refund data collection: Automatically capture the data of customs declaration forms,invoices and bills of lading,generate tax refund declaration packages,and eliminate manual input errors
- Tax refund progress tracking: Directly connect to the tax bureau system to view the status of declaration acceptance,review and tax refund arrival in real time

The export value of Manager Lei’s enterprise increased by 40% year-on-year in the first half of 2026,but the average arrival cycle of tax refund was only 28 days,15 days faster than the industry average.This benefits from Zhongshen’s "tax refund pre-review" service: before the formal declaration,tax accountants conduct simulated audits to correct doubts in advance.In June 2026,this service helped a new energy enterprise in Longgang identify the wrong tax rate application of an invoice,avoiding a tax refund loss of nearly 500,000 yuan.

## Summary of the Core Value of Zhongshen’s Services

Manager Lei has calculated an account: building a customs,logistics and financial team by itself costs more than 800,000 yuan a year,and it is difficult to cover all risk points.After entrusting Zhongshen,the total fixed service fee plus variable operation fee is about 450,000 yuan,a cost reduction of 44%.More importantly,Zhongshen has increased the maritime export compliance rate of Manager Lei’s enterprise to 99.8%,achieving zero customs penalties,zero foreign exchange verification,and zero tax refund delays in the first half of 2026.

This value is reflected in four levels: first,risk isolation,all declaration responsibilities are borne by the agency; second,efficiency aggregation,the coordination between the Shanghai headquarters and the Shenzhen office realizes "order receiving in Shanghai,operation in Shenzhen,nationwide service"; third,data connectivity,the single window connects the four systems of customs,taxation,foreign exchange administration and port; fourth,cost optimization,the discounts on freight rates,insurance premiums and operation fees brought by the scale effect are directly transferred to customers.

For Longgang manufacturing enterprises,choosing an agency like Zhongshen,which has been deeply engaged in the industry for more than 20 years,essentially outsources non-core businesses and concentrates resources on product R&D and market expansion.The international trade environment in 2026 requires professional division of labor more than ever.When every link of the maritime shipping chain is controlled by an experienced team,enterprises can truly realize the stable operation of "peace of mind once goods are shipped,tax refund arrives immediately".

| Service Dimension | Enterprise Self-operation | Zhongshen Agency | Value Difference |
| --- | --- | --- | --- |
| Compliance Risk | Bear the declaration responsibility by itself,high penalty risk | The agency bears the main responsibility,with pre-audit mechanism | Risk transfer,penalty rate reduced by 90% |
| Time Cost | Each shipment takes 6-8 hours | Clients only need 0.5 hours to provide basic information | Efficiency improved by 85% |
| Capital Cost | No discount on freight rate and insurance premium,long tax refund cycle | Group purchase price,accelerated tax refund channel | Comprehensive cost reduced by 30-40% |
| Abnormality Handling | Lack of emergency resources,passive waiting | 24-hour response,alternative solution library | Abnormality resolution efficiency improved by 70% |
