# Huangpu Customs Import Agency Services: Full Process Breakdown from Document Pre-audit to CIQ Inspection

## I.Status Quo and Challenges of Southeast Asian Tropical Fruit Import at Huangpu Port

In the first quarter of 2026,the import volume of Southeast Asian tropical fruits at Shanghai Huangpu Port increased by 18% year-on-year,with durian,mangosteen,longan and other categories accounting for the main share.Behind this growth,import enterprises are not facing a smooth path.The sea freight time from Laem Chabang Port,Thailand to Shanghai Huangpu Wharf is about 7 days,but if there is any negligence in the customs clearance link,it is common for goods to be detained at the port for 3-5 days.Problems such as non-conforming phytosanitary certificate format,missing packaging box labels,and substandard cold treatment data have directly pushed the inspection rate to more than 40%.What is more difficult is that the General Administration of Customs implemented a new risk classification management for imported fruits in 2026,and the sampling proportion of products from some production areas has increased.Enterprises operating on their own often encounter return or destruction due to unfamiliarity with the detailed rules.

According to Manager Ruan from Zhongshen,last year,a trading company imported pitayas from Vietnam.As it did not verify the orchard registration information in advance,it found that the supplier was not on the access list only after the goods arrived at the port,and the entire container of goods was forced to be returned,with a loss of more than 200,000 yuan.Such cases are not rare at Huangpu Port.The cold chain storage cost at the port starts from 1,000 yuan per day,and container detention fees and port demurrage fees are superimposed layer by layer.Under the dual squeeze of time cost and capital pressure,the value of professional customs declaration agents has become increasingly prominent.

## II.Core Role of Zhongshen in Import Agency

Customs declaration agency is not simply document transfer.Zhongshen’s operation logic at Huangpu Port is pre-risk control and process node connection.Imported fruits involve three main lines: customs,inspection and quarantine,and foreign exchange administration,with more than 20 links of document circulation.Manager Ruan’s team will intervene before the goods are loaded,check the orchard registration number,packaging plant code,phytosanitary certificate template,and confirm whether the cold treatment temperature curve meets the requirements.This pre-intervention mode intercepts problems overseas and avoids passivity after the goods arrive at the port.

The agency service also reflects professional depth in tax and fee calculation.Fruit commodities involve the superposition of multiple taxes such as MFN tariff rate,agreement tariff rate,value-added tax and consumption tax.Under the RCEP agreement in 2026,Thai durian can enjoy zero tariff with the certificate of origin,but enterprises need to meet the direct transportation rule and submit the non-reprocessing certificate.Zhongshen’s customs system can automatically match the tariff code,calculate the comprehensive tax burden,and remind customers to prepare supporting documents for the certificate of origin.This accuracy is far beyond the reach of the financial departments of ordinary enterprises.

## III.Full Process Breakdown of Huangpu Customs Import Agency

### 1.Document Pre-audit and Access Qualification Confirmation

Documents are the pass for imported fruits.Zhongshen requires customers to submit scanned copies of a full set of documents 72 hours before the departure of the goods,including certificate of origin,phytosanitary certificate,packing list,invoice,contract,bill of lading and cold treatment report.Manager Ruan’s team will check each document one by one: whether the phytosanitary certificate indicates the container number and seal number,whether the format of the certificate of origin complies with RCEP origin rules,and whether the cold treatment temperature continues to meet the standard.The electronic quarantine system newly launched by the customs in 2026 requires OCR recognition of uploaded certificates,and format deviation will lead to automatic order rejection by the system.

- Orchard registration number verification: log in to the access list database of the General Administration of Customs to confirm whether overseas orchards and packaging plants are within the validity period
- Packaging box label specification: must indicate the orchard registration number,packaging plant code,batch number and country of origin,with a font height of no less than 5mm
- Cold treatment data verification: check the data of the temperature recorder during transportation to ensure that the temperature is kept between -1and 2for more than 15 consecutive days
- Certificate endorsement requirement: the phytosanitary certificate must be signed by an official quarantine officer of the exporting country and affixed with an official seal,and copies are invalid

### 2.Port Customs Declaration and Tax & Fee Calculation

24 hours before the arrival of the goods,Zhongshen declares to Huangpu Customs through the single window.The key points of customs declaration form filling are commodity code classification and price declaration.Taking Thai Musang King durian as an example,the HS code is 0810600000,the MFN tariff rate is 20% in 2026,and the RCEP agreement tariff rate is 0%.Manager Ruan will guide customers to prepare freight invoices and insurance premium vouchers to prove the integrity of the transaction price.During customs price verification,if the declared price is found to be more than 15% lower than the average market price in the same period,the price inquiry procedure will be initiated.At this time,the agent needs to submit supporting materials such as overseas procurement contracts,payment slips and email exchange records,and conduct multiple rounds of consultations with the customs price department.

In the tax and fee payment link,Zhongshen provides two modes: tariff guarantee insurance and consolidated tax payment.The former is suitable for customers with small single import volume,who can release goods first and pay tax later with the insurance policy; the latter is suitable for customers with more than 5 import shipments per month,who can pay tax centrally before the 5th working day of the next month to revitalize cash flow.Huangpu Customs promoted "intelligent document examination" in 2026,and standardized declaration forms can be released in seconds,which puts forward higher requirements for document accuracy.

### 3.CIQ Inspection and Quarantine Release

Fruits are legal inspection commodities and must undergo on-site inspection and laboratory testing.Zhongshen’s inspection applicant will make an appointment for the inspection period in the electronic inspection and quarantine system in advance to avoid queuing.At the inspection site,customs officers will open the box to check whether the goods match the documents,and take samples to the laboratory for testing of pesticide residues,heavy metals and pests.According to the new regulations in 2026,durian products need additional testing of sulfur dioxide residue,and the testing cycle is extended from 3 working days to 5 working days.

Manager Ruan shared an operational detail: the temperature control of the inspection site directly affects the inspection efficiency.In high temperature in summer,customs officers will give priority to inspecting pre-cooled containers to shorten the unpacking time.Zhongshen’s cooperative units will transfer the containers to the pre-cooling area near the inspection platform one hour before the ship berths,maintaining a -2environment.This detail processing can shorten the inspection time by 40 minutes and reduce the risk of goods losing temperature.If the laboratory test is unqualified,the agent needs to submit a rectification plan within 24 hours and apply for re-inspection or return processing.

## IV.Practical Case: Mr.Geng’s Durian Import Customs Clearance Experience

Mr.Geng runs a high-end fruit wholesale business in Shanghai.In February 2026,he purchased the first batch of 20 tons of Musang King durian from Thailand.After the goods were loaded,he learned that the phytosanitary certificate provided by the supplier did not indicate the cold treatment container number.According to the conventional process,the customs will determine that the certificate does not conform after the goods arrive at the port,and require return or destruction.Introduced by peers,Mr.Geng urgently contacted Manager Ruan from Zhongshen.Manager Ruan intervened 48 hours before the goods arrived at Huangpu Port,guided the Thai supplier to apply for certificate correction from the local quarantine department,and coordinated with the shipping company to issue the full cold chain transportation certificate.At the same time,Zhongshen submitted a situation explanation to the customs in advance and applied for correction of certificate information remarks.

After the goods arrived at the port,the customs inspection officer found that there was information difference between the certificate and the actual goods,and planned to start the return procedure.Manager Ruan brought the correction letter issued by the Thai authorities,the cold treatment data record of the shipping company,and the verification report of the overseas company of China Certification & Inspection Group,and communicated face to face with the customs.After three rounds of consultation,the customs agreed to accept the correction materials,and transferred the goods to the designated cold treatment warehouse for 24-hour continuous cooling verification.After the verification was qualified,the goods were finally released,which took 2 more days than the normal process,but avoided the loss of the entire container return.Mr.Geng calculated: the agency fee expenditure was 12,000 yuan,but the 350,000 yuan worth of goods was saved,and the additional port cost only increased by 6,000 yuan.Since then,Mr.Geng has handed over all his monthly three containers of durian business to Zhongshen for agency.

## V.Value Summary of Professional Agency Services

More than 200 fruit customs declaration forms are declared at Huangpu Port every day,and the inspection rate remains at a high level of 35%.If an enterprise builds its own customs team,it needs to deploy at least three staff members: customs declarant,inspection applicant and document handler,with an annual labor cost of more than 300,000 yuan.Zhongshen’s agency service converts fixed costs into variable costs,charging per shipment,so enterprises do not need to bear hidden expenses such as personnel management,system maintenance and policy training.More importantly,the inspection case base and customs communication channels accumulated by the agency company are resources that are difficult for enterprises to replicate.Manager Ruan’s team compiles customs policy briefings every month and analyzes abnormal inspection data,which feeds back to customers and helps adjust procurement strategies.

In 2026,the customs implemented the "voluntary disclosure" system,and enterprises that find violations in self-inspection can be exempted from punishment.Zhongshen assists customers to sort out import records of the past three years,and voluntarily discloses problems such as low price declaration and incorrect application of certificate of origin,successfully avoiding administrative penalties.This transformation from passive response to active management is exactly the core value of professional agents.The import channel competition at Huangpu Port is fierce,and choosing an experienced agent is essentially purchasing risk filtering capability and time value.

| Document preparation time | 3-5 working days | 1 working day | 60% efficiency improvement |
| Inspection rate | 45%-50% | 25%-30% | 40% risk reduction |
| Handling time for abnormal problems | 5-7 working days | 2-3 working days | 60% cycle shortening |
| Comprehensive cost (per container) | 18,000-22,000 yuan | 12,000-15,000 yuan | 25% cost saving |
| Return risk rate | 8%-10% | Below 1% | 90% loss reduction |
