In the first quarter of 2026,the throughput of cold chain containers at Tianjin Port increased by 17% year-on-year,with Southeast Asian fruits accounting for over 40% of the total.Tropical fruits such as Thai durian,Vietnamese pitaya,and Philippine bananas are radiating to the North China and Northeast China markets through Tianjin Port.Behind this growth,importers face not only the dividend of booming market demand,but also multiple pressures from iterative quarantine standards,refined document requirements,and compressed port operation timelines.Zhongshen has been rooted in the foreign trade agency field for over 20 years.When handling food import businesses at Tianjin Port,we found that most customer losses do not occur in the tariff link,but are stuck in seemingly routine details such as document discrepancies,label defects,and excessive sampling results.

Tianjin Port,as the first port in northern China to implement the "two-stage access" reform,has changed its inspection logic for imported food.After goods arrive at the port,the customs first conducts surface compliance review,and then carries out substantive inspection after releasing the goods into the warehouse.This model puts forward higher requirements for importers’ preparatory work.Manager Ou of Zhongshen encountered a case at the end of 2025 when handling a batch of Vietnamese mangosteens: the Latin scientific name on the phytosanitary certificate provided by the customer had a single letter difference from the access list,resulting in a 4-day detention of the goods at the port.This issue is not an isolated case in Southeast Asian fruit imports,but a systemic risk.

Document Pre-screening: Avoid Compliance Risks at the Source

The document system for importing Southeast Asian fruits is three times more complex than that for conventional goods.The first layer consists of official certificates issued by the exporting country,including phytosanitary certificates,health certificates,and certificates of origin; the second layer includes trade documents such as invoices,packing lists,contracts,and bills of lading; the third layer consists of additional documents complying with Chinese regulations,such as label samples,ingredient descriptions,and cold chain temperature records.After accepting an order,Zhongshen first launches the "three-document cross-verification" mechanism: cross-compare foreign official certificates,trade documents,and domestic access lists.

Manager Ou shared a typical case: in February 2026,a customer imported Malaysian Mao Shan Wang durian.The processing method marked on the phytosanitary certificate provided by the exporter was "frozen",but the Chinese access list requires "fresh or frozen" for this item.This subtle wording difference is easily overlooked during rapid document review,but may trigger technical questions from the customs.Zhongshen’s pre-review process mandates a word-for-word comparison between certificate text and the access list,and immediately initiates a correction procedure with the foreign issuing authority if discrepancies are found,avoiding passive situations after goods arrive at the port.

Zhongshen has established a "document template library" for major Southeast Asian fruit varieties,and preset correction plans for more than 20 common discrepancies based on the certificate issuance habits of Thailand,Vietnam,the Philippines,Malaysia and other countries.This pre-processing has kept the one-time document pass rate above 92%,far higher than the industry average of 67%.

Port Customs Declaration: Operational Characteristics and Declaration Strategies of Tianjin Port

Tianjin Port implements a "classified management" model for food imports.Based on three dimensions: cargo risk level,enterprise credit level,and historical compliance record,customs declaration forms are automatically divided into green channel,regular channel,and key inspection channel.Zhongshen’s long-term data accumulation shows that the inspection rate for Southeast Asian fruits will naturally rise by 15%-20% during the two peak seasons of March-May and September-November each year,which is directly related to the port’s inspection manpower allocation cycle.

The core of the declaration link is "complete elements".The customs requires up to 38 declaration elements for fruit goods,among which the four items of "brand,specification,grade,and production period" are most prone to errors.Manager Ou pointed out that after the customs H2018 system upgrade in 2026,the review logic for the "brand" field has changed,and it no longer accepts the general declaration of "no brand",but requires the "registered orchard name" or "exporter’s registered trademark" to be filled in.This change has led to a large number of declaration forms using old templates being returned.

Tianjin Port has strict timelines for in-port operations of cold chain goods.The standard time limit from unloading to transporting to the designated cold container yard is 6 hours.Exceeding the time limit will not only generate detention demurrage,but also trigger additional customs inspection due to abnormal temperature.After connecting with the port’s data system,Zhongshen has realized the "vessel arrival and document arrival" synchronization mechanism,completing pre-declaration before the vessel berths,ensuring that the customs declaration form is in the release-to-be-inspected state after goods are unloaded,and maximizing the compression of in-port stay time.

Commodity Inspection: Practical Responses to Sampling Testing and Label Compliance

Commodity inspection for Southeast Asian fruits focuses on three areas: pesticide residues,heavy metals,and alien organisms.In 2026,the customs sampling rate for Southeast Asian fruits remained at 8%-12%,but the sampling rate for varieties on the key monitoring list can reach 100%.Zhongshen’s experience is that instead of passively waiting for sampling results,it is better to proactively send samples for pre-inspection.

In 2025,Manager Ou handled a batch of Philippine bananas.The customer refused pre-inspection to save costs.After the goods arrived at the port,they were selected for testing,and the result showed azoxystrobin residue of 0.3mg/kg,exceeding the Chinese standard of 0.1mg/kg.The entire batch faced return or destruction.Zhongshen urgently coordinated to transfer the goods to the customs-designated technical rectification warehouse,and finally reduced the residue value to 0.08mg/kg through ozone degradation treatment,saving nearly 800,000 yuan in losses.The lesson from this case is that pesticides used in some Southeast Asian producing areas have stricter limits under Chinese standards,so pre-inspection is a necessary risk control measure.

Label compliance is another frequent issue.Starting from January 1,2026,imported fruit labels must add the printing requirement of "traceability code for entry inspection and quarantine certificates".Many foreign exporters failed to update their label templates in time,resulting in non-compliant labels when goods arrive at the port.Zhongshen’s solution is to provide label designs compliant with China’s latest regulations during the document pre-screening stage,require foreign printing plants to produce according to the confirmed draft,and eliminate label problems at the source.

Supporting Services for Warehousing,Logistics and Foreign Exchange Settlement

The dependence of Southeast Asian fruits on cold chain means that warehousing and logistics cannot be disconnected.Zhongshen has signed contracts with three types of cold storage around Tianjin Port: in-port temporary storage warehouse,inspection and rectification warehouse,and distribution transfer warehouse.The in-port temporary storage warehouse is used for short-term storage of goods before release,with temperature controlled at -18℃ to -22℃; the inspection and rectification warehouse is equipped with technical processing equipment for pesticide residue degradation and fumigation pest control; the distribution transfer warehouse is close to expressways,facilitating rapid distribution.

In March 2026,a customer imported Thai mangosteens,and the release instruction was delayed by 24 hours due to a customs system failure.Zhongshen immediately activated the emergency plan,transferring the goods from the standard cold container to the in-port mobile cold storage,avoiding detention demurrage,and coordinating the customs to give priority to processing,finally completing release within 48 hours.This flexibility is based on early in-depth familiarity with port resources.

In the foreign exchange settlement link,Southeast Asian trade generally uses US dollars or RMB for settlement.Zhongshen’s foreign exchange services include letter of credit review,T/T payment,and exchange rate locking.In 2026,RMB exchange rate fluctuations intensified,and Zhongshen advised customers to handle forward foreign exchange settlement synchronously when signing contracts to lock in costs.Manager Ou reminded that some small exporters in Vietnam and Thailand have the risk of document fraud,and settlement via letter of credit with third-party inspection requirements can effectively avoid fraud.

Practical Case: Complete Cycle of Thai Durian Import

In April 2026,a fresh food e-commerce company in Hebei imported Thai durian for the first time,entrusting Zhongshen with full agency.After taking over,Manager Ou first found that the quality clause in the contract signed by the customer with the Thai exporter was vague,only stating "first-grade products" without specifying quantifiable indicators such as fruit weight,pulp yield,and Brix degree.This would埋下隱患 for subsequent claims.Zhongshen immediately requested to supplement the technical annex,refining the standards to "each fruit weighs 3.5-4.5kg,Brix degree not less than 28°Brix,pulp yield not less than 35%".

During the document pre-screening stage,the packaging plant registration number on the phytosanitary certificate was found to be "suspended" on the official website of the Thai Ministry of Agriculture and Forestry.Zhongshen urgently contacted the Thai exporter,requested to replace it with a qualified packaging plant to reissue the certificate,and adjusted the shipping schedule to avoid arrival of goods without documents.After the goods arrived at the port,the customs selected them for testing focusing on heavy metal cadmium.Zhongshen arranged pre-inspection in advance,and the result showed 0.02mg/kg,far lower than the Chinese standard of 0.05mg/kg,and the goods finally passed inspection smoothly.

The entire cycle from booking to picking up the goods took 11 days,including 3 days of in-port operation,which is 4 days shorter than the customer’s historical self-operation record.In terms of cost,by avoiding risks such as detention demurrage,port detention,and unqualified testing,the comprehensive cost was reduced by about 6%.This case reflects the value of professional agency: it is not simply running errands and submitting documents,but identifying risks and carrying out pre-processing at each node.

The complexity of food import at Tianjin Port lies in that it is not a single point of problem,but potential risk points in every link of the chain.Zhongshen’s operation mode is "node control + process series",transforming more than 20 years of experience into an executable standard action library,realizing the transformation from "passive response" to "active management" for high-risk products such as Southeast Asian fruits.For importers,choosing such an agency essentially uses fixed service fees to hedge against uncertain loss risks,which is particularly necessary in 2026,a year when quarantine standards continue to tighten.
