# In-depth Analysis of Import Agent Tax Payment: Full Process Costs and Compliance Essentials

## Regulatory Background and Practical Operational Difficulties for Importing Infant Formula from New Zealand

In 2026,China’s infant formula market is projected to exceed 200 billion yuan,with imported brands dominating the mid-to-high-end market.As the world’s largest dairy exporter,New Zealand’s infant formula,with its pure milk source,strict quality control and mature formula system,is the first choice for the Chinese market.However,this product is not ordinary food; it is subject to cross supervision by the General Administration of Customs,the State Administration for Market Regulation,and the National Health Commission,involving multiple dimensions such as food safety,nutritional formulas,label identification,and tariff policies.Enterprises importing on their own often encounter substantial obstacles in four links: HS code classification,composite tax rate calculation,inspection and quarantine standards,and Chinese label compliance.A typical case is that a batch of goods was required to be rectified by port commodity inspection due to a slight deviation in the labeling of nutritional components on the label from the latest national standard GB 10765-2021,resulting in the entire batch of goods being detained in the port area for more than two weeks.The resulting container detention fees,warehousing fees and capital occupation costs directly swallowed the expected profits.More seriously,if the inspection and quarantine are unqualified,the enterprise will not only face the risk of return or destruction,but may also be included in the customs credit downgrade list,affecting all subsequent import businesses.

Zhongshen has been engaged in import customs clearance services at the Shanghai Port for more than 20 years,and has handled infant formula cases covering major New Zealand brands and formula series.The team led by Manager Wu found that the core difficulty of importing such products is the superposition of tax costs and compliance risks — the composite calculation of customs duty,VAT and consumption tax is prone to errors,and the sampling standards of inspection and quarantine and the laboratory testing cycle directly affect the speed of cargo release.If an enterprise lacks experience,it is difficult to accurately estimate the total cost and total time before declaration.After the customs launched the "Smart Inspection" system in 2026,although some processes have been digitized,the system’s requirements for data consistency have become higher.Any minor contradiction between documents may trigger manual inspection,extending the release time by 3-5 working days.

## Document Pre-review: Identify Risk Points in Advance

The document system for importing infant formula is much more complex than that for ordinary food.In addition to conventional contracts,invoices,packing lists and bills of lading,more than ten documents must be provided,including health certificates issued by the New Zealand authorities,certificate of origin (for applying preferential tariff rates under free trade agreements),registration number of the manufacturing factory in China,product formula registration certificate (issued by the State Administration for Market Regulation),composition analysis report,Chinese label sample,organic certification certificate (if applicable),and GMO test report (if applicable).Since 2026,the customs has stricter review of the direct shipment rules for certificates of origin,requiring full transport documents from New Zealand to China,including detailed records of the port of loading,port of transshipment (if any),and port of discharge,to prove that the goods have not been recontainerized or processed midway.For goods transshipped via Singapore or Hong Kong,a non-processing certificate is also required,otherwise the zero-tariff preferential treatment under the China-New Zealand Free Trade Agreement cannot be enjoyed.

Zhongshen’s document pre-review service focuses on helping customers identify breaks and contradictions in the document chain.Once a company under Supervisor Liu planned to import a New Zealand organic infant formula.During the pre-review,Manager Wu found that the organic certification certificate was issued by a small New Zealand institution not listed in the China Certification and Accreditation Administration’s list of overseas organic certification institutions.This means that the policy convenience for organic product promotion cannot be enjoyed,and the customs may question the validity of the certificate and require additional supporting materials.After detecting this problem in advance,Supervisor Liu adjusted the marketing strategy in time to avoid subsequent compliance risks.Another common problem is the validity period management of formula registration certificates.In 2026,the State Administration for Market Regulation requires the renewal of formula registration certificates every five years.Manager Wu’s team will remind customers to pay attention to the certificate expiration date six months in advance to prevent the entire batch of goods from being unable to clear customs due to expired certificates.

Another key focus of the pre-review link is the compliance review of Chinese labels.According to the "Inspection Regulations for Labels of Imported Infant Formula Milk Powder" implemented in 2026,Chinese labels must be printed on the minimum sales package and cannot be affixed additionally.The label content must cover more than 20 elements including product name,ingredients list,nutritional composition table,eating method,storage conditions,production date,shelf life,country of origin,importer information,formula registration number,and warning statements (such as "Breast milk is the best food for infants aged 0-6 months").Zhongshen’s team will check word by word the consistency between the label sample and the filing information,and simulate the perspective of inspection and quarantine personnel to check whether details such as font height (no less than 1.8mm),contrast,and warning statement position meet the review standards.Once,the label of a New Zealand milk powder was required to be rectified because the unit of "folic acid" in the nutritional composition table was marked as "μgDFE" while the filing information was "μg".Manager Wu pointed out that although the two values are equivalent,the unit expression must be completely consistent,and such a detail difference is enough to cause inspection failure.

## Port Customs Declaration: Accurate Classification and Tax Calculation

The core of the declaration link is HS code classification and tariff rate application.Infant formula is usually classified under HS code 1901.10,but the specific subdivision depends on factors such as product form (powdered,liquid),applicable age group (0-6 months,6-12 months,1-3 years old),and whether it contains special added ingredients (such as probiotics,DHA,lactoferrin).A difference in a single letter or number in classification may cause the customs duty rate to change from 0% (under free trade agreements) to 5%,and even affect the calculation basis of VAT and consumption tax.In 2026,the customs has particularly strict review of the classification of "special medical use infant formula".If the product adds deeply hydrolyzed protein or amino acid formula,it may be classified under HS code 2106.90 (other food products),which has a customs duty rate of 12% and cannot enjoy free trade agreement preferential treatment.

When handling New Zealand milk powder,Zhongshen’s customs declaration team focuses on three key tasks:

![Are Import Tax Risks and Costs High? How Professional Agents Solve Your Problems](https://cndpic.sh-zhongshen.com/uploads/tradepics/ffrLKndKQW4Dq.webp)

- **Origin Rule Determination**: Verify whether the product is completely produced in New Zealand,and whether auxiliary materials such as whey powder and lactose also meet the free trade agreement origin standards.In 2026,the customs has tightened the application conditions for the cumulation rule.If the value of auxiliary materials exceeds 40% of the product’s FOB price,the zero-tariff preferential treatment may not be enjoyed.Manager Wu will require the New Zealand factory to provide a list of auxiliary material sources and calculate the regional value content to ensure compliance with origin standards.
- **Price Rationality Review**: The customs has strict monitoring of the declared price of infant formula,especially the transaction price between affiliated enterprises.Manager Wu will assist customers in preparing materials such as price composition instructions,third-party market comparison data,and New Zealand local retail price references to respond to customs price inquiries.In 2026,the customs introduced big data risk analysis,which will automatically trigger inspections for declared prices that are more than 15% lower than the industry average.It is crucial to prepare sufficient supporting materials in advance.
- **Composite Tax Calculation**: Accurately calculate the superposition effect of customs duty,VAT and consumption tax (if applicable).In 2026,the consumption tax for infant formula that meets national standards is 0%,but the 13% VAT must be calculated based on the sum of the customs dutiable value plus the customs duty amount.Manager Wu’s team has developed an internal accounting tool that can automatically output accurate tax amounts after inputting the FOB price,freight and insurance premiums,with an error rate controlled within 0.5%.For a batch of New Zealand milk powder with a value of 500,000 yuan,the tax difference between correct classification and incorrect classification may be as high as 25,000 yuan.

For tax payment methods,Zhongshen provides two options: First,electronic payment,where the customer transfers the tax amount to the customs-designated account in advance,with fast release speed,suitable for goods with high time requirements; second,guarantee mode,where a deposit is paid first to pick up the goods for situations where there are classification disputes or prices to be verified,with more or less settlement later,suitable for scenarios where the risk is controllable but quick release is needed.Supervisor Liu once encountered a batch of high-end infant formula where the customs had objections to the classification corresponding to the declared DHA content.Manager Wu suggested adopting the guarantee mode.After paying a 100,000 yuan deposit,the goods were picked up first to avoid long-term detention.When the classification dispute was finally resolved,the deposit was smoothly converted into tax payment without affecting the sales plan.If you choose to wait until the classification is confirmed before paying taxes,the goods will be detained for at least two weeks,and the resulting container detention and warehousing fees may exceed the guarantee interest cost.

| Tax Payment Method | Applicable Scenarios | Advantages | Disadvantages | Capital Occupancy |
| --- | --- | --- | --- | --- |
| Electronic Payment | Complete documents,no classification disputes,high time requirements | Fast release,usually 1-2 working days | Need to prepare full tax amount in advance | Full tax amount,about 13-18% of cargo value |
| Guarantee Mode | Classification disputes exist,price to be verified,need to pick up goods quickly | Pick up goods first and pay taxes later,high flexibility | Need to apply additionally,process slightly more complicated | Guarantee amount is usually 50-100% of tax amount |

## Commodity Inspection Link: Coordinate Testing and Fast Release

The inspection and quarantine of infant formula is the link with the most uncertain cycle in the import process.The inspection and quarantine departments under the port customs will sample batches and send them to the laboratory for testing items such as melamine,aflatoxin M1,microbial indicators (total bacterial count,coliform,salmonella,etc.),and heavy metals (lead,arsenic,mercury,chromium).In 2026,the testing standards have become stricter,adding limit requirements for chlorates and perchlorates,referring to the latest EU standards with a limit value of 0.01mg/kg.In addition,stability testing of added ingredients such as DHA and ARA has also become a routine item.

The value of Zhongshen in this link is reflected in its coordination and follow-up capabilities.Manager Wu’s team has established regular communication mechanisms with major port laboratories,and can query the testing progress in real time.For projects with a testing cycle exceeding ten days,they will take the initiative to coordinate the laboratory to give priority processing.For marginal data detected in the test,they will obtain detailed information immediately to judge whether it is a laboratory error or a product problem.Once,the total bacterial count of a batch of New Zealand milk powder was close to the upper limit in the initial inspection.Manager Wu immediately coordinated a retest and simultaneously requested the New Zealand factory to provide production environment monitoring records and raw material microbial test reports for this batch.It was finally proven that it was a contamination problem during the laboratory sampling process.The retest was qualified,and the goods were released,avoiding a return shipment cycle of nearly three months.

Label inspection is another key focus of commodity inspection.In 2026,the customs has implemented a dual-track system of "on-site inspection + post-market traceability" for label compliance verification.On-site inspection focuses on checking whether the label content is consistent with the filing information,and post-market traceability verifies the authenticity of the label through market sampling.Zhongshen will prepare label filing materials in advance,and coordinate inspection and quarantine personnel to inspect the label first after the goods arrive at the port to ensure no problems before laboratory sampling.Even if the laboratory testing takes two weeks,the label problem will not become an additional delay factor.Once,the font of the formula registration number on the label of a New Zealand milk powder was slightly smaller than the required 1.8mm,which was pointed out by the on-site inspection personnel.Manager Wu immediately provided a rectification plan,affixed a temporary label that meets the requirements at the warehouse site (allowed to affix a temporary label outside the minimum sales package for rectification),and took photos for filing.The inspection and quarantine personnel confirmed and passed it,and the entire rectification process only took half a day without affecting the overall release progress.

## Practical Case: Avoid Classification Errors and Port Detention Risks

In early 2026,the company under Supervisor Liu planned to import a batch of special medical use infant formula from New Zealand to meet the needs of infants with milk protein allergy.This product added deeply hydrolyzed whey protein,and Supervisor Liu’s team classified it under HS code 1901.10 for ordinary infant formula during declaration.After the goods arrived at the port,the customs questioned that its added ingredients exceeded the basic formula scope and should be classified under HS code 2106.90 (other food products),which has a customs duty rate of 12% and cannot enjoy free trade agreement preferential treatment.If classified accordingly,this batch of goods with a value of 800,000 yuan would pay an additional 96,000 yuan in customs duty,and the product could not use the filed Chinese label due to the change in tax code,requiring re-design and printing.The entire supply chain cycle would be delayed by at least one month,missing the peak sales season.

After Zhongshen intervened,Manager Wu did three key things: First,retrieved the "Registered Catalogue of Special Medical Purpose Formula Foods" issued by the State Administration for Market Regulation,proving that the product has obtained a special medical food registration certificate,belongs to a clearly regulated special category,and should be supervised as infant formula; second,sorted out the customs classification decisions over the years and found three classification precedents for similar products,all declared under HS code 1901.10,forming classification support materials; finally,conducted professional communication with the customs classification department and submitted a written classification proposal,detailing the differences in product formula,applicable population,and supervision standards from ordinary milk powder.After three working days of consultation,the customs recognized Zhongshen’s classification claim,and the goods were declared under HS code 1901.10 and enjoyed zero tariff.

The deep value of this case is that if the classification error was not corrected,Supervisor Liu’s company would not only pay an additional 96,000 yuan in customs duty,but also could not use the filed Chinese label due to the change in tax code,requiring re-design and printing.The entire supply chain cycle would be delayed by at least one month,missing the peak sales season.More seriously,if the goods had been released under the wrong tax code and later found by customs post-release inspection,it would be认定 as incorrect tariff code declaration,facing a fine of 10%-50% of the cargo value and affecting the enterprise’s credit rating.Manager Wu’s advance intervention directly avoided about 150,000 yuan in additional taxes and incalculable market opportunity losses,while ensuring the stability of the enterprise’s customs credit rating.

## Comprehensive Value of Professional Agents for Import Efficiency and Risk Control

The entire process of infant formula import is superficially the circulation of documents and data,but essentially an art of balancing compliance risks and cost control.The 20 years of experience accumulated by Zhongshen lies in advancing risk identification to the contract signing stage,accurately calculating costs to two decimal places,and refining process collaboration to the responsibility list of each position.Manager Wu’s team updates the "Compilation of Import Regulatory Policies for New Zealand Infant Formula" every month,covering the latest notices from the customs,market supervision,and health commissions,to ensure that the operation basis is always up to date.

For import enterprises like Supervisor Liu,the most direct benefits of entrusting Zhongshen to handle tax payment and customs clearance are reflected in three aspects: First,time efficiency: the cycle from cargo arrival at the port to release is controlled within 7-10 working days for conventional goods,which is 5-8 days faster than the average time for enterprises to operate on their own,thanks to Zhongshen’s regular communication mechanism with various port departments; second,cost certainty: all taxes and potential risks can be clearly estimated before shipment,with no hidden costs,and customers can develop sales pricing strategies based on accurate cost data; third,compliance safety: each link is backed by a professional team,and even in case of customs inspection or policy adjustment,they can respond quickly and provide complete compliance proof chains,avoiding enterprise credit downgrade.

In 2026,the import regulatory environment will only have higher requirements for professionalism.Zhongshen continues to track policy updates from the General Administration of Customs,the State Administration for Market Regulation,and the National Health Commission,and regularly updates internal operation manuals.Manager Wu’s team reviews typical cases every week,transforming the latest inspection priorities of regulatory authorities into customer operation guidelines.This depth of service capability cannot be replaced by simple software systems or standardized processes.When enterprises hand over the complexity of import tax payment and customs clearance to Zhongshen,they can focus on core businesses such as channel expansion and brand marketing.This is the real value brought by professional division of labor.For enterprises that hope to operate import business stably for a long time,choosing a professional agent like Zhongshen is not a simple cost expenditure,but a strategic investment that can bring deterministic returns.
