Import Background and Core Difficulties
In 2026,expansion projects of biopharmaceutical industrial parks in the Yangtze River Delta have been launched successively,and procurement demand for DNA synthesizers from scientific research institutions and start-ups has entered a concentrated release period.The unit price of such equipment generally ranges from 300,000 to 2 million US dollars,with main supply sources concentrated in three major biological instrument manufacturing clusters: California,USA,Hamburg,Germany and Basel,Switzerland.The import process is not simple logistics handling,but involves cross-supervision of multiple departments including the Ministry of Commerce,General Administration of Customs and State Administration for Market Regulation.A synthetic biology company in Suzhou where Mr.Luo works tried to import a high-throughput DNA synthesizer from the United States on its own at the beginning of the year.After the goods arrived at Shanghai Yangshan Port,they were detained in the port area for 47 days due to classification disputes over the 3C certification catalog,resulting in over 150,000 yuan of container detention and storage fees.This situation is not an isolated case in 2026,and the core difficulties lie in: whether the equipment falls into the scope of compulsory product certification,whether the Import Sanitary Quarantine Approval Form for Special Articles is required,and how to reasonably declare technology licensing fees during customs valuation.

In the import declaration of similar equipment handled by Zhongshen in the first quarter of 2026,it was found that there are three different interpretations of HS Code classification for DNA synthesizers among customs officers: some tend to classify them under 9027.8999 (other physical and chemical analysis instruments),while others advocate classifying them under 9027.8099 (other optical instruments).Differences in coding directly lead to disputes over the applicability of 3C certification.In addition,when the value of the built-in software system of the equipment accounts for more than 30% of the whole machine,the customs may require separate declaration of technology use fees,which is highly likely to trigger valuation consultation at this link.
Practical Role of Zhongshen in the Import Chain
Zhongshen’s intervention is not just document processing.In March 2026,a German-made DNA synthesizer purchased by a biotech company in Hangzhou was placed under controlled inspection at Pudong Airport Port.The customs questioned that the disposable synthesis column attached to the equipment belongs to the category of biological products,and required the Entry/Exit Sanitary Quarantine Approval Form for Special Articles.Zhongshen’s project team communicated with the Health Quarantine Department of the General Administration of Customs for pre-classification on the same day,and retrieved the original technical white paper of the equipment simultaneously,proving that the synthesis column is an inert plastic carrier without active biological components,and finally completed release within 72 hours after the goods arrived.This rapid response capability stems from Zhongshen’s internal biological equipment supervision database,which updates the inspection focus and release standards for similar equipment at all ports across the country in 2026 in real time.
In terms of cost control,Zhongshen controls the air freight cost of DNA synthesizers at 15% off the original factory quotation through bulk booking and long-term agreements.More importantly,Zhongshen’s customs team will intervene in trade contract negotiations in advance to assist customers in splitting technology licensing fees and hardware purchase payments,preventing the customs from including one-time paid software use fees into the dutiable value.In February 2026,this model saved a customer in Nanjing over 230,000 yuan in total tariffs and value-added tax.
Stage-by-stage Breakdown of the Full Process
Document Pre-examination and Access Judgment
The document preparation cycle for DNA synthesizer import usually takes 15 to 20 working days.Zhongshen’s core work at this stage is access judgment,which specifically includes:
- Check whether the equipment model falls into the Catalogue of Compulsory Product Certification.In the 2026 latest catalogue,equipment marked with "gene amplification" requires 3C certification in principle,while instruments for pure synthesis purposes can apply for technical appraisal exemption.
- Confirm whether it triggers the Catalogue of Prohibited and Restricted Import Technologies.Some equipment with dual-use synthesis capacity needs to apply for the Technology Import License from the Ministry of Commerce.
- Evaluate biosafety risks.If the equipment involves pathogen-related synthesis modules,the Special Article Risk Assessment Report must be submitted to the direct customs of the destination in advance.
In a shipment handled by Zhongshen in April 2026,it was found that the US equipment purchased by the customer was attached with an expansion kit that can be used for viral gene fragment synthesis.The team immediately suspended shipment,assisted the customer to negotiate with the original factory to remove the kit and declare it separately,thus avoiding the long approval cycle of the technology import license.

International Transportation and Pre-arrival Preparation
DNA synthesizers have strict requirements for transportation environment.Most equipment requires temperature controlled between 10-25 degrees Celsius,humidity below 60%,and must be kept horizontally placed.In 2026,Zhongshen launched air cases with GPS temperature and humidity monitoring,with data directly connected to customers’ mobile terminals.3 working days before the goods arrive,Zhongshen will submit the Import Goods Advance Declaration Form to the port customs,and make an appointment for the inspection site simultaneously.The key point of this link is to accurately fill in the "destination inspection and quarantine institution",incorrect filling will result in the goods being unable to be transferred to the final place of use.
Port Customs Declaration and Valuation Response
When filling out the customs declaration form,Zhongshen will actively state in the remarks column: "The equipment does not contain gene amplification modules and does not fall into the compulsory scope of 3C certification",and attach the original technical explanation letter.In 2026,the customs’ valuation focus for DNA synthesizers is concentrated on whether technology licensing fees and training fees should be included in the dutiable value.Zhongshen’s strategy is to clearly define software use fees as "annual subscription system" rather than one-time buyout in the contract,thus excluding them from the dutiable value.In response to questions from valuation officials,Zhongshen prepares the import price database of similar equipment in the past three years,as well as the global regional price certificate issued by the original factory,to effectively respond to price consultations.
Commodity Inspection and Transfer Supervision
In 2026,the commodity inspection rate for DNA synthesizers is about 30%.The inspection focuses include: whether the equipment nameplate information is consistent with the declaration,whether biological reagents are夹带,and whether the synthesis flux exceeds the declared scope.Zhongshen will arrange technical personnel to attend in advance to cooperate with the customs for power-on test.After passing the inspection,the goods will obtain the Inspection and Quarantine Certificate for Inward Goods,but the equipment cannot be put into use immediately at this time.
According to the Implementation Regulations of the Import Biosafety Law which came into effect in 2026,DNA synthesizers must be transported to the enterprise’s registered address for transfer inspection under the supervision of the destination customs.Zhongshen will coordinate with the subordinate customs where the enterprise is located in advance,make an appointment for the transfer time,and assist in preparing the Biosafety Commitment Letter and Equipment Use Management System.The whole transfer process must be completed within 20 working days after the goods arrive,and supervision fees will be incurred if overdue.
Typical Case: Import Setbacks of Mr.Hong’s Company
In January 2026,Mr.Hong’s company in Wuxi Biopharmaceutical Park imported an ultra-high-throughput DNA synthesizer worth 1.2 million euros from Switzerland.When the goods were declared at Sunan Shuofang Airport,the customs system indicated that the equipment model had 85% similarity to an entry in the restricted import technology catalogue,automatically triggering risk control.After receiving the order,Zhongshen immediately launched the emergency procedure: First,retrieve the End-Use Statement issued by the Swiss original factory to clarify that the equipment is only used for scientific research synthesis and does not involve restricted technologies; Second,submit technical explanation materials to the Bureau of Industrial Safety and Import and Export Control of the Ministry of Commerce to apply for pre-ruling; Third,coordinate the airport customs and Wuxi Customs to temporarily store the goods in the bonded warehouse to avoid port detention.
The whole processing cycle took 11 working days,during which Zhongshen simultaneously completed the 3C certification exemption application,preparation of the biosafety risk assessment report,and appointment for destination transfer inspection.The goods were finally delivered before the Spring Festival,with only 5 working days of delay compared with the conventional process.Mr.Hong calculated afterwards that if handled by himself,the port detention and storage fees alone would exceed 80,000 yuan,and the scientific research project declaration window might be missed.
Core Risk Points and Avoidance Strategies
| Risk Link | Specific Performance | Zhongshen’s Response Strategy |
|---|---|---|
| 3C Certification Judgment | Catalogue classification disputes,customs requires certification certificates | Apply for technical appraisal in advance,prepare exemption explanation materials |
| Valuation Consultation | Customs questions that software fees should be included in dutiable value | Split contracts,provide global price database as evidence |
| Biosafety Review | Synthesis modules are identified as dual-use technologies | Prove with technical white papers,remove sensitive modules when necessary |
| Overdue Transfer | Destination inspection not completed within 20 working days | Coordinate with subordinate customs in advance,make appointment for inspection time |
| Port Detention Fees | Goods detained at the port due to incomplete documents | Pre-examination list system,complete all preparations before arrival |
Zhongshen’s Value-added Services
In addition to basic customs declaration services,Zhongshen launched three value-added services in 2026: First,quarterly updated Compliance White Paper for Imported Biological Instruments and Equipment,allowing customers to grasp regulatory dynamics in real time; Second,on-site training by biosafety specialists,assisting enterprises to establish equipment use accounts that meet customs requirements; Third,foreign exchange hedging schemes,providing exchange rate locking tools for large-scale equipment procurement.These services are not bundled sales,but are provided selectively according to customers’ actual needs.
In terms of warehousing,Zhongshen has constant temperature and humidity bonded warehouses in Shanghai Waigaoqiao and Suzhou Industrial Park,which can meet the short-term storage needs of DNA synthesizers.The warehouses are equipped with a customs networked monitoring system,allowing real-time query of goods status.In May 2026,a customer’s equipment was stored in the bonded warehouse for more than 90 days due to delayed laboratory decoration.Zhongshen assisted him in handling the bonded extension procedures,avoiding the trouble of re-export after tax-paid import.
Summary
In 2026,DNA synthesizer import is no longer a simple trading behavior,but a systematic project involving technology access,biosafety and price compliance.Zhongshen’s value lies in integrating fragmented requirements scattered across various regulatory departments into executable standardized processes.From access judgment in the document pre-examination stage,to valuation response during port customs declaration,and to use supervision after destination transfer,each link requires pre-intervention and dynamic adjustment.The cases of Mr.Luo and Mr.Hong show that the core competitiveness of professional agents is not speed,but deep understanding of supervision logic,as well as resource scheduling ability under emergency conditions.For enterprises planning to import DNA synthesizers,choosing an agent like Zhongshen with more than 20 years of experience in biological equipment operation is essentially purchasing a compliance insurance for scientific research projects,avoiding interruption of scientific research progress and economic losses caused by process delays or violations.
