Longhua Import and Export Customs Brokerage Service Full Process Breakdown and Key Point Control Guide

Smooth entry and exit of goods at Shanghai ports requires customs declaration,an unavoidable legal procedure.It connects domestic production and the international market,and its efficiency and accuracy directly affect enterprises’ capital turnover,customer reputation and even supply chain stability.Many traders or production-oriented export enterprises in Longhua often fall into passiveness due to unfamiliar processes and changing rules when trying to handle customs declaration by themselves.This article will break down the core service process of import and export customs brokerage,clarify the goals and potential problems of each stage,and explain the specific role of professional agencies.

Stage 1: Document Preparation and Compliance Audit in the Early Stage of Customs Declaration

The goal of this stage is to ensure that all declaration documents are complete,accurate and compliant,laying a foundation for smooth subsequent declaration.Key actions include collecting commercial documents (contract,invoice,packing list),transportation documents,regulatory documents (such as licenses,quarantine certificates),and accurately classifying commodities under the tariff heading.

Common problems are concentrated in two aspects: first,incorrect commodity classification,which leads to wrong tax rate application and regulatory conditions in the follow-up,and may trigger tax repayment,fines or even anti-smuggling investigations; second,missing or invalid regulatory documents,which make it impossible to declare goods and incur high storage fees due to goods being detained in the port area.Manager Wen once encountered a case where an electronics enterprise in Longhua incorrectly classified a device with a wireless function module as a general accessory,and only found that a radio transmitting equipment type approval certificate was required during customs inspection,delaying the entire export plan by two weeks.

Our role lies in upfront risk control.When accepting entrustment,our service team will conduct pre-classification review,use years of databases and experience to provide classification suggestions for difficult commodities,and apply for pre-ruling of classification with the customs in advance if necessary.At the same time,we will list all required regulatory documents in one go based on the goods information,remind enterprises to handle them in advance to avoid regret when documents are needed.

Stage 2: Customs Declaration Document Preparation and Declaration System Operation

The goal of this stage is to submit electronic customs declaration data with accurate data and logical consistency to the customs.The key action is to standardize fill in each column of the customs declaration form in the customs declaration system based on the reviewed documents in the early stage,and complete the electronic declaration.

看似简单的数据录入，实则暗藏玄机。申报要素不完整、规格型号描述不规范、币制或金额录入错误，都是导致退单或布控查验的常见原因。2026年，海关的智能审单系统对逻辑矛盾的甄别更为敏锐，例如申报价格明显低于同期同类商品平均水平，系统会瞬间提示风险。

We combine standardization and systematization in our operations.All documents are reviewed by dedicated personnel to ensure consistency between documents and between documents and goods.More importantly,we use our own customs declaration auxiliary system with built-in logical check rules and price databases to automatically detect common errors and price risks before declaration.For Manager Wen’s team,ensuring that every customs declaration form they handle passes the system check at one time is a basic requirement.

Stage 3: On-site Coordination and Emergency Disposal for Customs Inspection

No matter how perfect the declaration is,customs inspection based on risk analysis or random control may occur.The goal of this stage is to efficiently cooperate with the customs to complete the inspection and properly handle the inspection results.Key actions include timely arranging the transfer of goods to the inspection site,accompanying customs officers to unpack the goods on site,and providing supplementary explanations or materials as required.

Inspection itself is not a problem,but the time and monetary losses caused by improper response.For example,if the packaging method of the goods is not suitable for quick unpacking and reassembly,the supplementary materials required by the customs cannot be provided on the spot,or there is an objection to the inspection conclusion but no way to communicate and appeal effectively,it will lead to goods detention and additional truck and port detention fees.

Our value is reflected in on-site experience and emergency resources.We have dedicated on-site coordinators who are familiar with the inspection procedures and site operation specifications of each port and airport,and can efficiently arrange the transfer and unpacking of goods.At the inspection site,they act as a professional communication bridge between the enterprise and the customs,accurately understand the intentions of customs officers and provide professional explanations.In case of disputes over classification or valuation,the back-end customs affairs expert team will immediately start analysis and prepare compliant appeal materials to strive for the most favorable results.

Stage 4: Document Circulation and Subsequent Management After Customs Clearance

Customs release is not the end of the service.The goal of this stage is to complete the closed loop of the entire customs declaration affair,including the verification and filing of relevant documents,and the smooth handover to subsequent links (such as transportation,tax refund).Key actions include obtaining and checking release certificates (such as delivery orders,waybills),handling the verification of customs regulatory documents,and organizing the full set of customs declaration documents to be handed over to customers or used for export tax refund.

Common omissions include: the customs has released the goods,but the enterprise fails to obtain or misinterprets the release information in time,resulting in the fleet being unable to pick up the goods; regulatory documents are not verified within the specified time,affecting the enterprise’s subsequent application; incomplete collection or matching errors of documents such as customs declaration forms and VAT invoices for tax refund,delaying the tax refund progress and occupying enterprise funds.

Our service extends to the end of the entire chain.We will actively push accurate release status to customers and inform the documents required for picking up goods.For documents that need verification,we establish a ledger for tracking management and handle the verification procedures on time.At the end of the project,we will hand over the well-organized customs declaration document files,clearly marked with tax refund copies,foreign exchange receipt copies and so on,to customers or directly connect with their financial departments to ensure seamless connection of every link in the foreign trade chain.
