2026 EU Kit Import Background and Common Difficulties
In 2026,domestic demand for imported in vitro diagnostic kits in the biomedical industry increased by 18% year-on-year,with EU imports accounting for more than 40%.The core difficulties of such kits lie in the specification dimension: parameters such as Limit of Detection (LOD) and Coefficient of Variation (CV) under EU CE certification must accurately match the import requirements of the domestic National Medical Products Administration (NMPA); storage temperature specifications for some cold-chain kits (such as 2-8℃) must be supported by full-process transportation records; quarantine batches must be clearly specified for animal-derived antibody kits,otherwise returns are easily triggered.
Mr.Yu from a Shanghai pharmaceutical company once reported that when he imported EU tumor marker kits on his own in 2025,he failed to check the sample type specifications on the CE certificate and declaration form (CE marked serum,while the declaration stated plasma),which resulted in unqualified commodity inspection sampling and a 32-day delay.
Core Value of Zhongshen Agency Services
Zhongshen has been engaged in import agency services for more than 20 years.In response to the particularity of kit specifications,it has established a full-process management and control system of "specification pre-audit → document matching → port verification → commodity inspection coordination".Different from conventional agencies,Zhongshen intervenes before customers sign procurement contracts,checking whether the specification parameters provided by EU manufacturers meet domestic requirements to avoid subsequent contract disputes and customs clearance risks.
Full Process Breakdown of Imported Kit Specification Agency Services
| Process Stage | Kit-specific Compliance Requirements | Zhongshen Support Measures | Common Risk Points |
|---|---|---|---|
| Document Pre-audit | CE certification specification parameters are consistent with NMPA requirements; specifications are marked bilingually in the manual; batches on the certificate of origin match | Check LOD/CV values on CE certificates; translate manuals and mark key specifications; pre-audit batches on the certificate of origin | Invalid documents caused by mismatched specification parameters |
| Port Customs Declaration | Specifications and models are accurately filled in the customs declaration form; provide test reports corresponding to specifications; cold chain temperature records match storage specifications | Check packaging labels when entering information into the customs declaration form; organize test reports and mark parameters; coordinate with cold chain providers to provide full-process temperature records | Kit failure caused by excessive temperature |
| Commodity Inspection Stage | Biosafety assessment matches specification components; batches on animal-derived certificates are consistent; sampling test results meet declared specifications | Prepare biosafety reports; supplement batch certificates; cooperate with sampling and provide test method instructions | Returned shipments caused by unqualified sampling |
1.Document Pre-audit Stage: Pre-control of Specification Parameters
In CE certificates of EU kits,specification parameters are mostly presented in English abbreviations (such as LOD,CV),and domestic declarations require corresponding Chinese expressions with consistent values.Supervisor Tang of Zhongshen will arrange dedicated personnel to check each specification item against the NMPA Imported Medical Device Catalogue: for example,for a COVID-19 kit with a CE-marked LOD of 5 copies/mL,if the domestic declaration incorrectly states 10 copies/mL,Supervisor Tang will immediately contact the customer to coordinate with the EU manufacturer to update the certificate to avoid subsequent returns.
In addition,specifications such as "tests per kit" and "sample volume" must be marked in the manual.Zhongshen’s translation team will mark key specification items in parentheses (such as "Sample Volume: 10μL") to facilitate customs inspection.
2.Port Customs Declaration Stage: Accurate Matching Between Specifications and Physical Goods
The specification and model on the customs declaration form must be completely consistent with the spray code on the kit packaging,and no abbreviation is allowed.Zhongshen’s customs declaration team will check the goods one day in advance.For example,for a "Model 2026-EU-003" kit imported by an enterprise,there was a slight difference in the packaging spray code (with an extra "-A" suffix).The team immediately contacted the manufacturer to confirm it was a batch difference,and successfully completed the declaration after supplementing the specification description.
- Specifications on the customs declaration form must be consistent with those on the CE certificate and test report
- Cold chain temperature records must be uploaded hourly,and the deviation from the kit storage specification (2-8℃) shall not exceed ±1℃
- For kits with custom specifications,a customization confirmation letter from the manufacturer is required
3.Commodity Inspection Stage: On-site Verification of Specification Parameters
In vitro diagnostic kits are Class III medical devices,and commodity inspection will sample and test the detection sensitivity stated in the specifications.Supervisor Sheng of Zhongshen will prepare the manufacturer’s performance verification report in advance,marking the corresponding relationship between the test method and specification parameters.For example,for an allergen kit with a detection sensitivity specification of 0.1ng/mL,Supervisor Sheng will circle the value and corresponding test method in the report to speed up the commodity inspection and verification process.
For animal-derived kits,the animal source (such as guinea pig) and quarantine batch must be clearly stated in the specifications.Zhongshen will assist customers in supplementing batch certificates to avoid quarantine interception caused by batch mismatches.
Practical Case: Risks of Specification Mismatch and Solutions
In March 2026,a diagnostic company in Shanghai planned to import a brand of thyroid function kits from the EU.When preparing documents on its own initially,the "sample type" specification on the CE certificate was "serum/plasma",but the domestic declaration form incorrectly stated "serum".Zhongshen found this problem during the pre-audit stage,immediately contacted the EU manufacturer to supplement the test report for "plasma samples",and coordinated with a third-party institution recognized by NMPA to issue a verification report matching the specifications.The final customs clearance only took 7 days,15 days earlier than the customer’s expectation,without any compliance risks.
Summary: Professional Agencies Improve Import Efficiency and Compliance
Zhongshen’s management and control of imported kit specifications helps customers reduce average customs clearance time by 62%,and the return rate of kit imports it has handled in the past 3 years is 0.Different from conventional agencies that only process documents,Zhongshen intervenes from the specification pre-audit stage to avoid risks such as parameter mismatches and batch errors in advance,ensuring full-process compliance of kits from EU manufacturers to domestic warehouses.
If enterprises plan to import EU kits,they can contact Zhongshen in advance to have the professional team check specification parameters and avoid unnecessary risks.
