Jinan Import Lactase Agent: 2026 Latest Customs Clearance Process and Compliance Key Points

Lactase Import Supervision Environment and Enterprise Practical Dilemma

In 2026,the demand for high-activity lactase in the deep processing of dairy products and the production of special medical food in Jinan and surrounding areas has entered a period of stable growth.The main sources of supply are concentrated in three major production areas: the Netherlands,Denmark and California,USA.Manufacturers in these regions have leading advantages in enzyme fermentation technology,and the product enzyme activity unit is stable,which meets the requirements of domestic high-end production lines.However,the practical resistance faced in the import link has not decreased with the growth of demand.The supervision of biological enzyme products by customs has been significantly tightened in the new round of catalog adjustment completed at the end of 2025.As a processing aid clearly listed in GB 2760 National Food Safety Standard for Food Additives Using Standard,lactase must not only meet the import requirements of ordinary food,but also comply with the quarantine regulations for industrial enzyme preparations in Announcement No.44 of 2011 issued by the former General Administration of Quality Supervision,Inspection and Quarantine.

When Manager Zhai took over the import project of a medium-sized dairy enterprise in Jinan in March 2026,the first batch of goods had been detained at Qingdao Port for 8 full working days.The problem lies in two details: the official foreign health certificate did not mark the corresponding relationship between the production batch number and the production date,and the marking method of enzyme activity unit on the Chinese label was inconsistent with the customs filing standard.This situation is not an isolated case.Many import enterprises in Jinan are used to treating lactase as an ordinary food additive,ignoring the extra quarantine level brought by its biological origin.The draft of Measures for Quarantine Supervision and Administration of Imported Bio-derived Food Additives issued by the General Administration of Customs in 2026 further clarifies that lactase needs to provide Animal Health Certificate or Phytosanitary Certificate issued by the official of the producing country,depending on the source of fermentation substrate.This requirement is often misjudged by grassroots customs brokers in actual implementation,leading to repeated corrections after document submission.

Positioning of Zhongshen in the Lactase Import Chain

Zhongshen has been handling the import of enzyme products since 2006,and has completed more than 400 batches of lactase customs clearance,with complete data records of operation differences among the three major ports of Jinan,Qingdao and Tianjin.Our role is not a simple customs broker,but a compliance consultant and risk buffer layer running through the front end of the supply chain.Before the goods are shipped,we will intervene in the document system of foreign suppliers,and pre-review their health certificate templates and component analysis report formats to ensure that they meet the implicit requirements of Chinese customs.This pre-intervention can reduce the document mismatch rate from the industry average of 23% to less than 5%.

In April 2026,a special medical food enterprise in Jinan planned to import a batch of pharmaceutical-grade lactase from Germany for the research and development of lactose-free formula powder.When reviewing the COA (Certificate of Analysis) provided by the other party,Manager Zhai found that the enzyme activity unit was marked as "ALU/g" (Acid Lactase Unit),while the domestic filing standard usually requires declaration in "NLU/g" (Neutral Lactase Unit) or "LACU/g" (Lactase Activity Unit).This unit difference seems to be a technical detail,but it may cause customs doubts about commodity classification,which in turn affects tariff rates and supervision conditions.Zhongshen then assisted the enterprise to communicate with the German laboratory,supplemented the unit conversion description document,and made technical remarks in the remarks column of the customs declaration form,avoiding disputes in subsequent inspections.

Disassembly of the Whole Lactase Import Process and Key Nodes

Stage 1: Document Pre-review and Access Confirmation

Before the goods leave the foreign factory,Zhongshen will launch a document verification list covering 17 key points.The core of this list is to identify the specific documents of lactase products.

• Official Health Certificate: It must reflect the quarantine conclusion that "the product is produced from non-epidemic area raw materials and suitable for human food use",and the batch number information must be completely consistent with the spray code on the outer packaging of the goods.In 2026,the inspection of certificate anti-counterfeiting marks by customs has been upgraded to QR code scanning verification,and forged or altered certificates will be directly handed over to the anti-smuggling department.
• Component Analysis Report: In addition to the enzyme activity unit,an additional explanation of protein source is required.If the fermentation substrate contains animal-derived components (such as whey protein),the Import Animal and Plant Quarantine License is required,and the processing cycle in Jinan is about 15 working days.
• Chinese Label Filing: The source of enzyme preparation on the label (such as "Aspergillus oryzae fermentation product"),scope of use (such as "only for dairy processing"),and storage conditions (such as "2-8℃ refrigeration") must be consistent with GB 26687 National Food Safety Standard General Rules for Compound Food Additives.In 2026,Jinan Customs has particularly strict examination of the word "non-GMO" on labels,requiring an official non-GMO statement from the producing country.

When handling a batch of American lactase goods in May 2026,Manager Zhai found that the foreign label marked "Non-GMO",but failed to provide the third-party non-GMO certification recognized by the United States Department of Agriculture.Zhongshen suggested that the enterprise reprint Chinese labels before the goods arrive at the port,delete the expression,and only retain necessary component information,thus avoiding the port detention cost caused by label rectification.

Stage 2: Port Customs Declaration and Tax Calculation

There are technical disputes over the commodity classification of lactase.According to the 2026 Import and Export Tariff Commodity and Heading Notes,lactase can be classified into 3507.90 (other enzymes) or 3507.10 (crude rennet).The former tariff rate is 6%,and the latter is 3%.The classification difference depends on product purity and use.Before customs declaration,Zhongshen will require enterprises to provide detailed process flow descriptions to judge whether it has undergone high purification.Lactase used for pharmaceutical intermediates is usually declared under 3507.90; for ordinary dairy processing,if the purity is lower than a specific threshold,it can be applied for declaration under 3507.10,which has successful precedents at Jinan Port.

Another key point of tax calculation is value-added tax.The import VAT rate of lactase is 13% in 2026,but some enterprises in Jinan can enjoy special zone policies outside the List of Retail Imported Commodities for Cross-border E-commerce.Zhongshen assisted an enterprise registered in Jinan Comprehensive Bonded Zone to postpone the VAT payment link to the time when finished products leave the zone through the mode of "first-line entry,intra-zone processing,second-line exit from the zone",effectively alleviating the pressure of capital occupation.

Stage 3: Commodity Inspection Sampling and Laboratory Testing

Lactase is a statutory inspection commodity,and the port customs will take samples according to the proportion of 2% to 5% and send them to the laboratory.In 2026,the testing items of lactase by Jinan Customs Technology Center include enzyme activity verification,heavy metal (lead,arsenic) residues,salmonella,staphylococcus aureus and other microbial indicators.The testing cycle is usually 10-12 working days.

The core work of Zhongshen at this stage is to coordinate the representativeness of sampling.Manager Zhai once encountered a batch of lactase in 25kg small packages.The customs randomly sampled 3 bags during sampling,but the laboratory feedback that the sample amount was insufficient to complete all projects.Zhongshen communicated with the inspection department in time to explain the sampling rules for small packaged goods,and finally adjusted to increasing the number of sampling bags but reducing the sampling amount per bag,which not only met the testing needs but also avoided enterprise losses.

More importantly,Zhongshen will require foreign suppliers to provide retained samples of the same batch of products in advance.Once there is a dispute over the laboratory test results,the retained sample retesting procedure can be started immediately,shortening the retesting cycle from the conventional 20 days to 7 days.In June 2026,a batch of Danish lactase of a Jinan customer was questioned by the customs because the enzyme activity test value was 3% lower than the declared value.Zhongshen quickly retrieved the retained samples from the Danish factory and entrusted a third-party laboratory for urgent testing.Finally,it was confirmed that the difference was caused by different testing methods,and the goods were released smoothly.

Real Case: Resolution of Return Risk Caused by Document Inconsistency

In February 2026,a large dairy enterprise in Jinan imported 5 tons of high-activity lactase from the Netherlands,with a cargo value of 480,000 euros.After the goods arrived at Qingdao Port,the customs found in the document review link that there was a slight difference between the name of the production enterprise on the official Dutch health certificate and the name declared on the customs declaration form: the certificate was "XX B.V.",while the customs declaration form was declared as "XX Co.Ltd." according to Chinese habits.This suffix difference is very common in EU enterprise naming,but the customs system judged it as "document inconsistency",requiring the enterprise to submit a description and return the declaration for modification.

At that time,there were only 2 working days left before the customs prescribed modification deadline.If it could not be completed,the goods would be transferred to the pending return state.After receiving the enterprise’s request for help,Manager Zhai immediately launched the emergency procedure: first,retrieve the Dutch official enterprise registration information database stored by Zhongshen to verify that "XX B.V." and "XX Co.Ltd." are indeed the same legal entity; second,contact the Dutch supplier to issue an enterprise name consistency statement with Apostille certification within 1 working day; finally,submit the Description of Enterprise Name Difference to the customs,attached with the official certification document issued by the Netherlands Chamber of Commerce.The whole set of documents was submitted within the time limit,and the customs accepted the explanation after review.The goods were released on the 3rd working day,avoiding the loss of freight and insurance premiums of about 120,000 yuan caused by return.

This case exposes a common shortcoming of import enterprises in Jinan: insufficient awareness of the legal effect of the legal entity suffix of EU enterprises.When dealing with similar problems,Zhongshen will suggest that enterprises file multiple names of the full legal name of foreign suppliers (including suffixes such as B.V.GmbH,LLC) in the customs system when filing for the first import,and establish an association relationship to eliminate such risks fundamentally.

Quantification of Core Value of Zhongshen Agency Service

The service value of Zhongshen is reflected in three quantifiable dimensions.The first is time cost.Through pre-document review and port relationship coordination,the average customs clearance cycle is reduced from the industry average of 18 days to 11 days.For enterprises adopting JIT production mode in Jinan,this means a 35% increase in inventory turnover rate.The second is economic cost.In the first half of 2026,among the lactase import business represented by Zhongshen,the supplementary tax rate caused by classification errors was zero,while the average supplementary tax rate of such commodities at Jinan Port in the same period was 7.3%.

The third dimension is compliance safety margin.Zhongshen establishes independent import files for each Jinan customer,recording historical documents,customs inquiry letters,and laboratory test reports,forming a traceable compliance evidence chain.In the "Imported Food and Cosmetics Safety Assurance Project" launched by the customs in 2026,such files became the key support for enterprises to obtain the "Advanced Certified Enterprise" qualification.Three Jinan customers served by Manager Zhai have passed the certification,enjoying lower inspection rates and priority customs clearance treatment in subsequent imports.

Decision Suggestions for Jinan Enterprises Importing Lactase in 2026

For Jinan enterprises planning to import lactase,Zhongshen suggests building internal processes from three levels.First,in the supplier selection stage,give priority to cooperating with foreign manufacturers that have experience in exporting to China,and require them to provide a complete package of Chinese customs filing documents,including health certificate templates,component analysis report samples,and label design drafts.Zhongshen can provide template review services to identify risk points before contract signing.

Second,in the design of logistics schemes,considering that the biological activity of lactase is sensitive to temperature,it is recommended to choose sea cold chain transportation,and clearly specify the "2-8℃ temperature control" clause on the bill of lading.Zhongshen has established data docking with cold chain inspection platforms in Qingdao and Tianjin ports,which can monitor the temperature record of goods during the port period in real time,avoiding quality disputes caused by temperature control chain breakage.

Finally,in terms of internal personnel allocation,it is recommended to assign a commissioner familiar with food regulations to connect with the agent,rather than completely relying on the procurement department.Zhongshen will equip each customer with an exclusive customer service and establish a WeChat work group to ensure real-time document transmission and information feedback.The frequency of customs policy adjustment in 2026 is accelerated,and there have been detailed updates in April and July respectively.The real-time communication mechanism can ensure that enterprises respond to changes as soon as possible.

As an important dairy processing base in North China,Jinan will continue to have demand for imported lactase.The value of Zhongshen is not in simple customs declaration operations,but in transforming 20 years of experience into executable standard operating procedures,helping enterprises transform uncertain compliance risks into predictable and controllable process costs.When the customs clearance cycle changes from uncontrollable to 11-day standard delivery,and the fine caused by document inconsistency drops to zero,enterprises can really focus on product research and development and market expansion,which is the ultimate significance of professional agency services.
