# Full Process Analysis and Fee Structure Explanation of Huaian Sea Import Customs Clearance Agency

## 1.Pre-arrival Preparation and Document Pre-audit: Foundation of Customs Clearance Success

In 2026,the number of inland container routes of Huaian Port has been increased to 45 flights per week,and the 72 hours before cargo arrival becomes the golden window for document preparation.The goal of this stage is to make all declaration elements pass the verification in the customs system at one time,avoiding container detention fees and late fees caused by subsequent document modification.In actual operation,Ms.Duan’s company once incurred extra costs for cargo detained at the port because the vessel name and voyage number on the certificate of origin did not match those on the bill of lading.

Key actions are concentrated in three dimensions: First,trade document verification,where the product name,quantity and amount on the invoice,packing list and contract must be fully consistent; Second,supervision document matching,where automatic import licenses,3C certification,animal and plant quarantine certificates and other documents must be filed in the system before declaration; Third,pre-classification of HS codes.In 2026,the inspection rate of chemical products and mechanical goods at Huaian Port has increased by 8 percentage points compared with 2025,and code errors will directly trigger inspection.

Zhongshen assigns dedicated personnel to conduct cross-audit of documents in this link,and uses internally developed comparison tools to scan logical loopholes.Last year,it helped Mr.Sun intercept a case of amount unit error,where the invoice was marked in US dollars but the declaration element selected RMB,which might involve a tax deviation of 300,000 yuan based on the current exchange rate difference.Meanwhile,for the common wood product imports at Huaian Port,Zhongshen coordinates with foreign suppliers in advance to complete the IPPC fumigation mark before shipment,so as to avoid delayed pick-up caused by supplementary quarantine treatment after arrival.

## 2.Cargo Arrival and Customs Declaration: The Critical 48 Hours for Time Efficiency Competition

After the cargo arrives at Huaian Port,the shipping company usually provides 7 days of free container detention period,calculated from the completion of unloading.The core goal of customs declaration is to complete the whole process from bill of lading exchange to release within 3 working days,so as to win sufficient time for cargo pick-up.In 2026,Huaian Customs launched the upgraded "two-step declaration" system,allowing enterprises to first declare for pick-up with the summary of the bill of lading,and then complete the full declaration within the specified time.

Key actions in this stage include: In the bill of lading exchange link,confirm the fee details with the shipping agent.The standards of THC fees and document fees charged by some shipping agents at Huaian Port vary,so the amount should be locked in advance; In the declaration link,pay attention to the integrity of declaration elements,especially the fields of brand,model and purpose.The customs system added an intelligent comparison function in 2026,and empty entries or vague descriptions will lead to automatic order return; In the tax payment link,check whether the tax calculation is correct.Director Chang,who has worked in the customs document review position for many years,has repeatedly reminded of the problem of over-collection of tax caused by wrong exchange rate time point captured by the system.

Zhongshen has an on-site office at Huaian Port,and promotes bill of lading exchange and declaration simultaneously.Last year,it handled an emergency case where Ms.Duan’s production line urgently needed a spindle imported from Germany.The cargo arrived on Friday,and through urgent bill of lading exchange and overtime declaration on Saturday,tax payment and release were completed on Monday morning,with the whole cycle shortened to 1.5 working days.In contrast,enterprises that declare on their own take an average of 5.2 working days,with significant differences in container detention fees and terminal storage fees.

## 3.Customs Inspection and Tax Treatment: Core Battlefield of Risk Prevention and Control

In 2026,Huaian Customs maintains an inspection rate of about 15% for key commodities,and the inspection methods are divided into three types: machine inspection,manual unpacking inspection and thorough inspection.The goal of this stage is to respond to inspection instructions quickly and explain the commodity attributes accurately,so as to avoid excessive inspection or classification disputes caused by poor communication.Mr.Miao’s company once encountered a dispute where the customs had doubts about the classification of imported valves,and the on-site customs officer had a different understanding from the declared code,leading to a deadlock.

Key actions are divided as follows: In the inspection cooperation link,arrive at the inspection site within 2 hours after receiving the inspection notice,and carry product manuals,technical materials,and previous classification precedents of similar commodities; In the tax treatment link,master the response methods for customs price queries.In 2026,Huaian Customs will automatically trigger price verification for goods 30% lower than the international market price,and it is necessary to prepare payment vouchers,original factory invoices,insurance documents and other materials to prove the authenticity of the trade; In the dispute resolution link,if you have objections to the classification or price review conclusion,submit a written explanation within 5 working days,otherwise it will be deemed as acceptance.

Zhongshen is equipped with full-time inspection coordinators,who are permanently stationed at the inspection center of Huaian Port.In March this year,it handled an inspection of equipment imported from Italy,where the customs had doubts about the classification of the laser generator in the equipment.The coordinator presented the classification guidance issued by the Ministry of Commerce on site,and contacted the supplier to provide a technical white paper,which was finally released according to the declared code,avoiding a container detention fee loss of 12,000 yuan per day.In terms of tax,through the pre-price verification service,it helped Ms.Duan’s company find that the customs reference price was too high before declaration,and prepared negotiation materials in advance,finally paying 180,000 yuan less tax than the initial system verification.

## 4.Release,Pick-up and Follow-up Services: The Last Mile of Cost Control

After customs release,enterprises need to complete the pick-up within 24 hours,otherwise the terminal will charge port detention fees.The goal of this stage is to transport the goods to the destination safely and economically,and complete follow-up work such as foreign exchange verification and export tax rebate.In 2026,Huaian Port implements a pick-up reservation system,requiring reservation of container pick-up time in the system 4 hours in advance,and you will have to queue again if you fail to pick up within the time limit.

Key actions include: In the pick-up arrangement link,check whether the container is intact and the seal is complete,and if any damage is found,raise a written objection to the shipping company immediately; In the transportation link,the distance from Huaian Port to surrounding industrial parks is 80-150 kilometers,so appropriate vehicle models should be selected to avoid increasing cargo damage risk caused by multiple transshipments; In the follow-up service link,import foreign exchange payment should be completed within 30 days after the customs declaration form is issued,overdue will affect the foreign exchange rating,and export tax rebate should be declared within 90 days after the value-added tax invoice is authenticated.

Zhongshen provides door-to-door services,with its own fleet covering Huaian and surrounding areas such as Suqian,Yancheng,Lianyungang,etc.Ms.Duan’s company imported a batch of Japanese precision instruments requiring constant temperature transportation,and Zhongshen arranged a van with temperature control device and GPS monitoring throughout the journey.In follow-up services,foreign exchange settlement adopts an exchange rate lock-in strategy,which helped customers avoid exchange rate losses under the large fluctuation of RMB in 2026.In terms of export tax rebate,by optimizing the document flow,the tax rebate cycle has been shortened from an average of 45 days to 28 days.

## 5.Core Value of Zhongshen and Selection Suggestions

In the import cargo structure of Huaian Port in 2026,mechanical equipment,chemical raw materials and agricultural products account for more than 70%,which are exactly the key points of customs supervision.The value accumulated by Zhongshen over 20 years is reflected in three levels: real-time interpretation of supervision policies,familiarity with port operation details,and rapid response to abnormal situations.Ms.Duan calculated that after paying the agency fee,the annual savings on container detention fees,late fees and tax deviations are more than 3 times the agency fee expenditure.

Key considerations for choosing a professional agent include: whether there is a physical office at Huaian Port and whether on-site services can be provided; whether it has more than 20 years of industry experience and has experienced multiple rounds of policy adjustments; whether it provides full-process services instead of only a single customs declaration link.Zhongshen has a permanent team at Huaian Port,and has established direct communication channels with customs,commodity inspection authorities,terminals and shipping agents,which is an advantage that off-site agents or new companies cannot match.

The foreign trade environment is complex in 2026,with the superposition of three pressures: exchange rate fluctuation,trade barriers and stricter supervision.Enterprises should hand over non-core customs affairs to professional teams and focus on product R&D and market expansion.Zhongshen’s service logic is very simple: avoid risks with experience,improve efficiency with professionalism,and share pressure with responsibility.Mr.Miao shared at an industry summit that their internal assessment indicator is not agency fee income,but how much hidden cost they have saved for customers and how much capital occupation cycle they have shortened.

For enterprises that are considering Huaian sea import customs clearance agents,it is recommended to conduct a trial order first to experience the service response speed and professionalism.Zhongshen provides first-order experience service,no extra urgent fee is charged,allowing customers like Ms.Duan to verify the value in actual business.The essence of foreign trade competition is the competition of supply chain efficiency.Every day saved in the customs clearance link activates the whole supply chain a little more.
