# 2026 Standard Process and Practical Operation Guide for Agent Export Customs Declaration

Export customs declaration is a legal procedure before goods depart the country,which directly determines customs clearance efficiency and compliance costs.In 2026,customs supervision continues to tighten,and declaration errors may lead to higher inspection rates,increased detention fees,and even damage to enterprises’ credit ratings.With over 20 years of industry accumulation,Zhongshen has broken down the full process into 6 controllable stages to systematically reduce operational risks.

## Phase 1: Export Qualification and Document Pre-check

The goal of this stage is to confirm the qualification of the declaration entity and the completeness of documents,to avoid order returns in subsequent links due to qualification defects.Key actions include verifying export operation rights,foreign exchange registry status,applicability of export tax rebate rates,and collecting basic documents such as invoices,packing lists,contracts,and draft bills of lading.Common problems focus on conflicting document information,such as a deviation of more than 5% between the invoice amount and the unit price declared on the customs declaration form,or logical errors in gross and net weights on the packing list.

Zhongshen has established a double review mechanism in this link: the document preparation team led by Supervisor Zheng conducts initial review,and the re-review team led by Supervisor Lu conducts spot checks.The newly added intelligent comparison system in 2026 can automatically identify more than 20 document logic conflicts,reducing human error rate to below 0.3%.For enterprises without import and export rights,Zhongshen provides a full set of qualification affiliation programs to ensure legal and compliant declaration.

## Phase 2: Commodity Classification and Confirmation of Supervision Requirements

Accurate classification is the foundation of customs declaration,which directly affects the applicable tax rates and supervision document requirements.In this stage,it is necessary to refer to the "Import and Export Tariff" and the "National Subheading Notes" revised in 2026 to determine the 8-digit HS code,and verify whether supervision conditions such as commodity inspection,quotas,and licenses are required.Key actions include physical verification,component analysis,function verification,and submitting a pre-classification application to the customs when necessary.

Common problems include classification disputes,such as new material products being questioned by the customs due to unclear tariff nomenclature,or commodities with high export tax rebate rates being classified into lower tax rate tariff items.Zhongshen’s classification database covers more than 5,000 difficult commodity cases,and the classification support team led by Mr.Miao provides real-time consultation.In 2026,Zhongshen assisted a photovoltaic enterprise to successfully adjust the component classification from 8541.40 to 8541.49,increasing the tax rebate rate by 3 percentage points,with an annual increase of over 2 million yuan in tax rebates.

## Phase 3: Customs Declaration Form Filling and Submission

Customs declaration form filling is the core operation link.In 2026,the customs has launched a new customs declaration form format,adding fields such as "brand type" and "export preferential treatment status".Key actions include: accurately filling in the operating unit,consigning unit,and domestic supply origin; standardizing the declaration of commodity names and specifications; correctly selecting trade terms and freight and insurance premium allocation methods.The declaration time window is usually 24-48 hours before shipment,which needs to be closely coordinated with the shipping schedule.

Common problems focus on price declaration and confirmation of special relationships.Manager Sheng reminds that in 2026,the customs has increased the review of related party transaction prices.If the special relationship is not declared truthfully,it may be identified as price fraud.Zhongshen adopts a "pre-declaration simulation review" mechanism,pre-filling the customs declaration form through the internal system,automatically verifying more than 30 logical rules,ensuring that the one-time pass rate reaches more than 98%.

## Phase 4: Customs Inspection and Abnormal Handling

Inspection is an important means of customs supervision.In 2026,the mechanical inspection rate has increased to 65%,and manual inspection has focused on intellectual property rights,brand authorization,and classification accuracy.The goal of this stage is to quickly respond to inspection instructions and cooperate with the customs to complete physical cargo verification.Key actions include: receiving inspection notifications in a timely manner,arranging cargo movement to the inspection area,preparing relevant documents for review,and explaining commodity attributes on-site.

A common problem is delayed shipment due to low inspection efficiency.The on-site coordination team led by Ms.Ji has established green channels with major port inspection departments,which can reduce inspection waiting time by 40%.Zhongshen provides "pre-inspection service",submitting technical materials to the customs in advance for high-risk goods to obtain exemption or fast inspection.In the first quarter of 2026,the inspection rate of goods entrusted by Zhongshen was only 1.2%,far lower than the industry average of 3.5%.

| Inspection Type | Trigger Reason | Processing Time | Zhongshen’s Response Plan |
| --- | --- | --- | --- |
| Mechanical Inspection | Random selection,risk parameter hit | 2-4 hours | Early declaration,appointment of inspection time slot |
| Manual Inspection | Price query,classification doubt | 4-8 hours | Technical document pre-review,on-site expert accompaniment |
| Comprehensive Inspection | Major risks,report clues | 1-2 days | Legal intervention,multi-channel coordination |

## Phase 5: Customs Clearance and Logistics Coordination

After customs release,customs clearance procedures must be completed within 24 hours to obtain the customs declaration form tax refund certificate.The goal of this stage is to ensure seamless coordination between logistics and customs declaration,avoiding additional costs caused by cargo detention in the port area.Key actions include: tracking release information,confirming shipping schedule dynamics,coordinating trucks to enter the port,and obtaining dock receipts.

Common problems focus on tight operating time windows in the port area,especially the night operation restrictions at Shanghai Yangshan Port.Zhongshen has signed annual agreements with multiple high-quality trucking companies to ensure sufficient transport capacity even during peak seasons.The "Customs Declaration-Logistics Linkage Platform" launched in 2026 can push port operation plans in real time,automatically match the optimal port entry time,reducing the average waiting time from 6 hours to 2.5 hours.

## Phase 6: Subsequent Verification and Tax Refund Declaration

Customs declaration form release is only the starting point.Subsequent foreign exchange verification and tax refund declaration directly affect enterprises’ cash flow.In 2026,the State Administration of Foreign Exchange simplified the verification process,but tax refund review has become stricter,requiring matching of the customs declaration form,invoice,and foreign exchange receipt.Key actions in this stage include: timely matching the customs declaration form after receiving foreign exchange,organizing tax refund filing documents,submitting tax refund applications through the electronic tax bureau,and responding to letter of investigation from tax authorities.

Common problems include delayed foreign exchange receipt leading to longer tax refund cycles,or inability to provide effective evidence during letter of investigation.Zhongshen provides "Tax Refund Butler Service",with the team led by Supervisor Zheng tracking the foreign exchange receipt progress throughout the process and preparing response plans for letter of investigation in advance.In 2026,the average tax refund cycle for clients entrusted by Zhongshen was reduced to 15 working days,50% faster than the industry average of 30 days.
