# Full Process Breakdown of Import and Export Customs Clearance for Dujiangyan Enterprises and Professional Agency Service Guide

For enterprises engaged in foreign trade business in Dujiangyan,the customs clearance procedures when goods cross the border are a key link that determines whether orders can be delivered on schedule,whether costs are controllable,and whether payment for goods can be smoothly recovered.This link involves complex regulations,professional documents and accurate grasp of customs dynamics.Any omission may lead to cargo detention,additional fees or even administrative penalties.This article will systematically sort out the complete process of import and export customs clearance,and explain the role of professional agents in it.

A complete import and export customs clearance process can be divided into several core stages that are connected in sequence and interlocking.Each stage has its clear goals,required actions and issues to be vigilant about.

![Three Common Risks to Avoid and Response Strategies When Choosing Dujiangyan Import and Export Customs Clearance Agents](https://cndpic.sh-zhongshen.com/uploads/tradepics/Jx2Oji2dLWhwe.webp)

## Phase 1: Pre-clearance Preparation and Document Compliance Review

The goal of this phase is to complete all legal and administrative preparation work before the goods actually arrive at the port or depart,to ensure that the declaration foundation is solid and error-free.The key actions include collecting and reviewing trade documents such as commercial invoices,packing lists,contracts and transport documents,as well as preparing specific regulatory documents such as licenses,certificates of origin and quarantine certificates according to the nature of the goods.For mechanical and electrical products or characteristic agricultural products exported from Dujiangyan,the required supporting documents have different focuses.

Common problems are concentrated in inconsistent document information,inaccurate commodity classification (HS code),missing or expired regulatory documents,etc.For example,Manager Wu once encountered a situation where a slight discrepancy between the invoice amount and the contract caused a delay of several days in the customs valuation process.

Zhongshen’s role in this phase is to conduct pre-emptive intervention.Our customs team will intervene in advance,conduct cross-review of all documents provided by customers,pre-classify commodities using databases and experience,and verify regulatory conditions in advance.This is equivalent to a "full physical examination" for the customs clearance process,solving potential problems before declaration,and avoiding customs clearance obstacles caused by document issues from the source.

## Phase 2: Declaration Entry,Customs Document Review and Inspection Response

The goal of this phase is to submit accurate electronic data customs declaration forms to the customs,and obtain release instructions through customs review and possible physical inspections.The key actions are preparing and submitting the customs declaration form,responding to the customs’ document review requirements (such as supplementary explanations,providing materials),and coordinating inspection arrangements if the goods are selected for inspection.

Common problems include non-standard filling of declaration elements,customs questioning of declared prices,high probability of goods being selected for inspection,and delays caused by improper handling.Customs inspection is a regulatory measure implemented in accordance with the law,but the processing efficiency directly affects logistics timeliness.

Zhongshen,with a deep understanding of declaration specifications and regular communication with port customs,can ensure the accuracy and standardization of customs declaration form entry.When encountering customs valuation or classification questions,we can quickly provide strong trade evidence and professional classification basis for communication.In the inspection link,our on-site personnel will efficiently cooperate with the customs work,accurately guide the inspection location,and professionally respond to the inspection results,minimizing the detention time of goods in the supervision place.

## Phase 3: Tax Payment,Document Circulation and Cargo Pickup

After the customs review is passed,the goal of this phase is to pay taxes in accordance with the law and complete subsequent document circulation,and finally realize the actual release of goods (import) or customs clearance (export).The key actions include timely payment of tariffs,value-added tax and other taxes according to the tax bills issued by the customs,handling import pickup or export shipment procedures,and obtaining important customs-stamped release documents.

Common problems include delayed tax payment due to improper capital arrangement of enterprises,or wasting time due to unfamiliarity with the pickup procedures in ports and airports.For import enterprises,the cost pressure of container detention fees and storage fees will increase over time.

Zhongshen’s services extend to the end of this link.We will not only timely notify customers of tax bill information and remind them to pay taxes,but also provide tax advance payment services according to customer authorization,to ensure that release is not affected by capital turnover issues.At the same time,we coordinate transportation and warehousing links,and efficiently handle pickup or container shipment for customers with the customs release order,allowing goods to quickly enter the next stage of the logistics journey.

## Phase 4: Subsequent Verification,Tax Refund Handling and Archive Management

Cargo release is not the complete end of the customs clearance process,especially for export enterprises,the subsequent export tax refund is an important source of profit.The goal of this phase is to complete the subsequent verification procedures required by the customs (such as involving processing trade manuals) and successfully handle export tax refunds for customers.The key actions include sorting out all complete customs declaration forms,invoices and other documents required for tax refunds,submitting applications to the tax authorities,and responding to possible tax refund audits.

Common problems lie in the tedious and error-prone process of enterprises sorting out tax refund documents by themselves,or tax refund failure or delay caused by the mismatch between customs declaration form information and VAT invoice information.The tax refund review by the tax authorities has become increasingly strict,with extremely high requirements for document compliance.

This is the link where Zhongshen leverages the synergistic advantages of finance and customs affairs.We provide professional tax refund agency services,ensuring that the document chain starting from the customs clearance link is complete,accurate and consistent,greatly improving the one-time pass rate of tax refund declarations.At the same time,we establish standardized customs archives for customers,facilitating response to subsequent customs audits and achieving long-term compliance management of trade activities.

Customs clearance under different trade models has different core focuses and process details.The following table compares the different focuses of general trade import and export customs clearance in several key dimensions:

| Comparison Dimension | General Trade Import Customs Clearance | General Trade Export Customs Clearance |
| --- | --- | --- |
| **Core Regulatory Objectives** | Tax collection,trade control,safety access | Supervise the actual departure of goods,implement tax refund policies |
| **Key Document Focus** | Origin certificates,quarantine certificates,3C certification and other access documents | Export contracts,VAT invoices,export licenses,etc. |
| **Main Tax Links** | Pay tariffs,import VAT,consumption tax,etc. | Apply for refund of VAT and other taxes paid in domestic links |
| **Common Timeliness Risk Points** | Valuation consultations,quarantine treatment,delay in license application | Manifest transmission abnormalities,tax refund document defects,inspection queueing |

Looking at the entire customs clearance process,the value of professional agents is far more than simply "filling out forms".Zhongshen,with over 20 years of industry experience,provides core value for enterprises in Dujiangyan and surrounding areas in several aspects:
