Practical Challenges of New Zealand Milk Powder Import at Shenzhen Port

In Q1 2026,the volume of dairy imports at Shenzhen Port increased by 18% year-on-year,while the rejection and destruction rate also rose to 4.3%.As China’s largest source of infant formula,New Zealand’s exported products face three tests at Shenzhen Port: First,the transition period of the Measures for the Administration of Product Formula Registration of Infant Formula Milk Powder has ended,and all imported products must complete formula registration; Second,Order No.248 of the General Administration of Customs requires overseas manufacturers to obtain a registration number in China; Third,Shenzhen Customs implements 100% container inspection for high-risk foods.Mr.Sun from a certain trading company once tried to import on his own,but failed to verify the registration qualification of the New Zealand manufacturer in advance,resulting in the entire batch of goods being detained at Shekou Port for 47 days,and finally incurring over 200,000 RMB in container detention fees and storage fees.

Among the 83 New Zealand milk powder import businesses handled by Zhongshen in 2025,61 involved registration qualification warning issues.We have established a dynamic database of New Zealand dairy enterprises,which synchronizes the registration information changes of GAC in real time,and completes the supplier compliance screening before the customer signs the contract.This pre-risk control model transforms post-hoc remedy costs into pre-hoc prevention investments.

Hidden Thresholds in Document Pre-check Stage

The document system for New Zealand milk powder imports is far more complex than that for ordinary goods.In addition to conventional invoices,packing lists,and bills of lading,it is necessary to provide sanitary certificates,certificates of origin,composition analysis reports,and radioactive substance test reports certified by the Ministry for Primary Industries (MPI) of New Zealand.New requirements in 2026 include: production enterprises must provide special test reports for trans fatty acids and 3-monochloropropane-1,2-diol esters,and the test laboratories must obtain CNAS accreditation.

Precise Control of Label Compliance

Shenzhen Customs implements a "dual-track review" for infant formula labels: it must comply with the National Standard of China GB 7718-2021 General Rules for Labelling of Prepackaged Foods,and also meet the special requirements of National Standard of China GB 10765-2021 Infant Formula Foods.The Zhongshen label pre-check team found that about 73% of New Zealand original label products have non-standard nutrition claims.For example,a brand marked "Rich in DHA" on the main front display surface,violating the regulation that nutrition component claims must indicate specific content values.We intervene in label rectification at the stage when the customer signs the purchase contract,provide templates that comply with Chinese regulations,and avoid rework after the goods arrive at the port.

• Sanitary certificates must indicate the production batch number and production date,and must be completely consistent with the spray code on the tank body
• Composition analysis reports should include the ratio of whey protein to casein,which affects product classification
• The validity period of radioactive substance test reports is 90 days,and the transportation cycle must be accurately calculated
• Sample Chinese labels must be submitted to the Food Department of Shenzhen Customs for filing 3 working days in advance

Classification and Valuation Risks in Port Declaration Stage

There are major misunderstandings in the HS code classification of infant formula.Many enterprises mistakenly classify ordinary children’s milk powder under HS code 0402.2900,while infant formula with added ingredients should be classified under HS code 1901.1000.The tariff rates of the two differ by 5 percentage points,and products under HS code 1901 need to submit an Automatic Import License.In February 2026,Shenzhen Customs retrospectively levied the tax difference for three years on an enterprise,because of the incorrect historical declaration code.

The valuation link also hides risks.Quantity discounts,annual rebates,market support fees,etc.given by New Zealand exporters will trigger price questioning if they are not declared truthfully in the "Special Relationship Confirmation" column of the customs declaration form.Mr.Jiang from Zhongshen handled a typical case: the customer signed an annual procurement framework agreement with the New Zealand supplier,which agreed to give a 3% rebate after the sales target was achieved.We actively disclosed the special relationship during the first declaration,and prepared complete pricing policy explanation documents.Customs finally accepted the declared price and did not initiate the price consultation procedure.

Key Control Points for Commodity Inspection Sampling and Testing

Shenzhen Customs Food Inspection and Quarantine Technical Center implements full-item testing for infant formula,with a cycle of 15-20 working days.The testing items cover 67 indicators including microorganisms,pollutants,mycotoxins,nutritional fortifiers,and illegal additives.In 2026,a new screening for phthalate plasticizers is added,with a detection limit requirement of 0.01mg/kg.

Zhongshen has established a green inspection channel with the Shenzhen Customs laboratory,and locks the testing position in advance through the pre-declaration system.A batch of goods in charge of Manager Gan completed the electronic declaration 3 days before the ship berths,realizing "sample immediately upon arrival,test immediately after sampling",and reducing the testing cycle to 12 working days.More importantly,we have established a rapid response mechanism for unqualified items: if the protein index of a batch is close to the standard limit,we immediately start the production process verification of the New Zealand factory,complete the preparation of rectification evidence chain before Customs issues the official unqualified notice,and successfully avoid the entire batch of rejection.

Temperature Control and Traceability in Warehouse Management and Distribution

Infant formula has strict requirements for warehouse temperature and humidity.Shenzhen’s summer is hot and humid,and ordinary bonded warehouses are difficult to meet the product stability requirements.Zhongshen has equipped a GSP-standard constant temperature warehouse in Shenzhen Pingshan Comprehensive Bonded Zone,with temperature controlled at 22±2℃,relative humidity ≤65%,and installed 24-hour video monitoring and automatic temperature and humidity recording systems.When each batch of goods enters the warehouse,synchronously collect the spray code on the tank body,production batch,warehouse entry time,and warehouse location number information,and generate a traceable QR code.

The maternal and infant chain customer served by Ms.Yang requires distribution to 30 stores in the Pearl River Delta.We adopt the model of "full batch warehouse entry,batch-wise warehouse exit,cold chain distribution".Use refrigerated trucks (2-8℃) for transportation,equipped with GPS positioning and temperature recorders,and the store signs for the temperature data when unloading.This entire cold chain management,although increasing logistics costs by 8%,reduces the customer complaint rate from the industry average of 3% to less than 0.5%.

Funding Efficiency Optimization in Foreign Exchange Payment and Receipt and Tax Refund

Most New Zealand milk powder imports use letter of credit settlement,and the letter of credit margin occupies the enterprise’s working capital.Zhongshen cooperates with banks to provide credit letter of credit services for high-quality customers,reducing the margin ratio from 30% to 15%.In the payment link,we use the New Zealand dollar exchange rate fluctuation window and adopt forward foreign exchange settlement and sale tools,reducing the customer’s exchange cost by an average of 1.2 percentage points in 2025.

In terms of export tax refund,infant formula applies a 13% tax refund rate,but must meet the dual conditions of "foreign exchange receipt + filing documents".Manager Mu’s team established a tax refund calendar reminder system,completes foreign exchange verification within 90 days after the goods are exported,and submits the tax refund application within 15 days after the electronic information of the customs declaration form is uploaded.Through the "non-contact" handling of the electronic tax bureau,the average tax refund cycle is shortened to 6.8 working days,and the capital turnover efficiency is increased by 40%.

Actual Combat Case: Avoiding Risks During Formula Registration Gap

In Q3 2025,a customer planned to import a certain brand of infant formula from New Zealand,but the brand’s formula registration certificate will expire in January 2026.Zhongshen found during document review that the validity period of the registration certificate could not cover the goods sales cycle.We immediately launched an emergency plan: first,coordinate with the New Zealand factory to speed up the registration renewal application,and submit the "Registration Certificate Renewal Application Acceptance Notice" to the General Administration of Customs; second,adjust the import plan,divide the originally planned 3 containers into batches for import,and only import 1 container in the first batch to reduce risk exposure; third,assist the customer in applying for the "Temporary Import License",allowing the goods to be stored in the warehouse first during the registration gap,but not sold,and handle the sales filing immediately after the new certificate is approved.

Finally,the batch of goods obtained the new registration certificate after waiting 28 days at Shekou Port.Although certain storage costs were incurred,the huge loss of the entire batch of rejection was avoided.Mr.Sun commented afterwards: "The value of Zhongshen does not lie in how fast the customs clearance is,but in discovering the compliance traps that we ourselves were not aware of in advance."

The Core Value of Professional Agencies Lies in Pre-positioned Risk Control

The tightening of import supervision at Shenzhen Port in 2026 is a deterministic trend.As a sensitive commodity with high social attention,the compliance requirements for infant formula will only become more detailed.What Zhongshen has accumulated over 20 years is not only proficiency in operating procedures,but also the establishment of a risk identification and prevention and control system.From supplier qualification verification,document pre-check,code classification,price declaration,to commodity inspection submission,warehouse temperature control,foreign exchange settlement,and tax refund handling,each link is equipped with risk control nodes and emergency plans.

The essence of choosing a professional agency is to transform uncertain compliance costs into predictable service fees.When the value of a batch of goods is 5 million RMB,paying an agency fee of 30,000 to 50,000 RMB avoids risks such as rejection,fines,and detention costs of more than 500,000 RMB.The 99.2% one-time release rate maintained by Zhongshen at Shenzhen Port and the average customs clearance time of 5.2 working days are finally transformed into the customer’s market competitiveness and brand reputation.In the highly specialized field of import trade,the value of experience cannot be measured by money,but can be verified by costs.
