# 2026 Customs Clearance Process and Compliance Key Points Analysis for Imported Ultra-Low Temperature Freezers

In 2026,demand for ultra-low temperature storage equipment in domestic biomedical R&D,clinical sample storage,and advanced materials science fields is showing steady growth.Many research institutions,hospitals,and biomedical enterprises tend to import low-temperature freezers from countries with strong precision manufacturing capabilities such as Germany,the United States,and Japan.Such equipment often has a high unit price and extremely strict requirements for the transportation environment.In actual import operations,enterprises not only face conventional tariff calculations,but also need to cope with complex mechanical and electrical product access licenses,handling of Compulsory Product Certification (CCC) exemptions or related certificates,and full-process cold chain monitoring challenges.Once there are omissions in document preparation or logistics links,it is very easy to cause goods to be detained at the port,resulting in high demurrage and warehousing fees,and even facing return risks due to compliance issues.

As a professional foreign trade import and export agency company that has been deeply engaged in the industry for more than 20 years,Zhongshen understands the pain points and difficulties in the import process of low-temperature freezers.We integrate core links such as international transportation,document review,foreign exchange payment,port customs declaration,and domestic distribution to create a full-process,one-stop agency solution for importers.In this process,we not only act as the operator of customs declaration and commodity inspection,but also play the role of enterprise compliance consultants,assisting customers in avoiding risks under complex regulatory policies and ensuring that the equipment is safely and timely put into use.

## Document Pre-Review and Compliance Confirmation

Low-temperature freezers are usually classified as mechanical and electrical products under customs supervision conditions,and some equipment with specific uses or temperature ranges may also be subject to medical device management.Before the goods are shipped,Zhongshen will assist customers in conducting detailed document pre-review,which is the first line of defense to ensure smooth customs clearance.We need to focus on reviewing the HS code classification of the product,because different codes correspond to different regulatory conditions,such as whether a "CCC" certification certificate is required,or whether an exemption certificate for "CCC" can be applied for.In addition,for some equipment included in the "Import License Management Goods Catalogue",automatic import licenses need to be handled in advance.

In the 2026 regulatory environment,energy efficiency labels are also a mandatory inspection item for imported refrigerator products.Zhongshen will guide foreign suppliers to accurately mark the energy efficiency level and ensure that the accompanying inspection report is completely consistent with the actual goods.We usually provide customers with a detailed document list,requiring foreign manufacturers to prepare all documents before shipment,so as to eliminate port inspection risks caused by inconsistent documents from the source.

- Review the consistency of basic information in trade contracts,invoices,packing lists,and certificate of origin
- Confirm the product HS code and check whether it involves Compulsory Product Certification (CCC) and energy efficiency label requirements
- For goods included in the legal inspection catalogue,prepare test reports that meet Chinese standards in advance
- If it is old mechanical and electrical products or equipment for specific scientific research purposes,guide the handling of CCC exemption certificates or import licenses

## International Transportation and Cold Chain Logistics Monitoring

For low-temperature freezers,especially ultra-low temperature freezers (such as -80),their internal compressors and refrigeration systems are extremely sensitive during transportation.Although there is no need to maintain extremely low temperatures inside the box during transportation,severe vibration and tilting must be prevented.Zhongshen will develop exclusive logistics plans based on the specific characteristics of the goods during the international transportation link.We usually recommend using air-cushion suspension trucks for short-distance transportation and professional shock-proof packaging materials in shipping containers.

Although the international logistics supply chain in 2026 is tending to stabilize,the uncertainty of shipping routes still exists.With rich shipping company resources,Zhongshen can secure more stable shipping space and shorter transportation time for customers.After the goods are shipped,we will track the logistics dynamics throughout the process to ensure that all transportation documents (such as bills of lading) have been transferred to the customs broker in time before the goods arrive at the Chinese port,so as to conduct advance declaration.This "declare upon arrival" model can minimize the dwell time of goods at the terminal and reduce potential risks.

## Port Customs Declaration and Legal Commodity Inspection Implementation

After the goods arrive at the declared port,they enter the core customs declaration and commodity inspection link.Zhongshen’s operation team will use the single window system to submit accurate declaration data to the customs.For low-temperature freezers,the key elements reviewed by the customs include: brand model,specifications,voltage,refrigerant type,and country of origin.As controlled chemicals,refrigerants of some models may require relevant environmental protection certificates.

At the same time as customs declaration,legal commodity inspection (legal inspection) is carried out simultaneously.The customs will inspect the goods according to the system instructions.Zhongshen’s customs officers will accompany the inspection,answer the customs’ questions about the goods’ parameters on site,and assist in opening the box to check the nameplate information.If the customs has doubts about the energy efficiency or safety performance of the product,the possibility of sampling and sending for inspection will greatly increase.At this time,our professional experience is particularly important.We can quickly communicate with the laboratory,coordinate the testing process,and shorten the waiting time for results.Once the taxes and fees are paid and the customs release the goods,the goods can be picked up from the port area.

To more intuitively show the risk points and response strategies of each link,we have summarized the following key control points:

| Process Stage | Core Operational Actions | Common Risk Points | Zhongshen Response Plan |
| --- | --- | --- | --- |
| Document Preparation | Review CCC certification,energy efficiency labels,mechanical and electrical licenses | Certification documents expired or information inconsistent with the actual goods | Pre-review before shipment,guide suppliers to rectify documents |
| International Transportation | Arrange air-cushion trucks,reinforce packaging,book shipping space | Compressor damage caused by vibration during transportation | Purchase all-risk transportation insurance,supervise loading and unloading operations |
| Port Declaration | Enter HS code,price,specification parameters | Incorrect HS code classification leading to tax supplement or fine | Professional classifier pre-classification,reduce inspection rate |
| Customs Inspection | Cooperate with customs to check nameplates,sampling and testing | Long sampling and testing cycle,resulting in port detention fees | Communicate in advance,coordinate urgent testing,rapid release |

## Case Sharing: Customs Clearance Record of Ultra-Low Temperature Freezer Import by a Scientific Research Institution

In early 2026,a biotech company in Shanghai specializing in gene sequencing technology R&D plans to import a batch of ultra-low temperature freezers from Europe to build a new biological sample bank.The company’s procurement director,Mr.Lu,contacted Zhongshen at the initial stage of the project.Mr.Lu’s main concern was that this batch of equipment is a new model,there is no exactly identical CCC certification case in China,and the project schedule is tight.The equipment must be installed and debugged before the end of the month,otherwise it will affect the subsequent sample storage work.

After taking over the project,Zhongshen’s project manager first conducted an in-depth analysis of the equipment’s technical parameters.It was confirmed that although the equipment belongs to refrigeration equipment,it is a laboratory-specific instrument that meets the CCC exemption conditions for "production equipment imported for scientific research,testing and other purposes".We immediately assisted Mr.Lu in preparing relevant explanatory materials for scientific research purposes and applied to the local market supervision department for the "Certificate of Exemption from Compulsory Product Certification".The early completion of this key step cleared the obstacles for subsequent paperless declaration.

After the goods arrived at the Pudong Airport port,the system triggered a random inspection.Due to the large volume of the goods and the need to rebox for inspection,the operation difficulty was relatively high.Zhongshen’s on-site customs broker quickly coordinated with the airport cargo terminal to arrange professional forklifts and operation teams to cooperate with the customs inspection.During the inspection,customs officials raised questions about the environmental protection model of the equipment’s refrigerant.We immediately retrieved the "Refrigerant Compliance Statement" and original factory test report prepared before shipment and submitted them to the customs officer for review on site.With detailed information,the customs approved it on the spot and quickly completed the cancellation of the inspection order.

From declaration to release,the entire process took less than 48 hours.Mr.Lu highly recognized Zhongshen’s response speed and professionalism.The equipment was finally delivered to the laboratory on time,avoiding the stagnation of scientific research progress caused by customs clearance delays.This case fully shows that when handling the import of instruments and equipment with high compliance requirements,choosing an experienced professional agency company can save enterprises a lot of time and communication costs.

## Summary

Importing low-temperature freezers is a systematic project involving multi-department supervision and multi-link collaboration.From the initial document compliance confirmation,to the middle-stage cold chain logistics guarantee,and then to the later port customs clearance and commodity inspection,every link hides risks.With 20 years of industry accumulation,Zhongshen can accurately identify these risk points and use a perfect operation system to minimize risks.For enterprises with import needs,leveraging the power of professional agents can not only improve customs clearance efficiency,but also ensure compliant import under the framework of strict laws and regulations,so as to devote more energy to the development of core businesses.
