2026 Perimeter Import Agency Company Full Process Compliance Customs Clearance Service

In the first half of 2026,the demand for perimeter renewal in domestic ophthalmic specialized hospitals increased by 22% year-on-year,among which high-end perimeters imported from Germany and Japan accounted for more than 60%.However,many heads of ophthalmic institutions reported that there are many "hidden pitfalls" in the import process - for example,the additional clauses of medical device CE certification updated by Germany in March this year,and the minor adjustment of radiation safety testing standards for optical instruments in Japan,have all caused setbacks for enterprises without professional agency.Last week,General Manager Wei of an ophthalmic center in Shanghai encountered trouble: the perimeter imported from Germany was temporarily stored by port commodity inspection due to the lack of "optical component radiation attenuation report" in the documents,with detention fee exceeding 2000 yuan per day.

As a company deeply engaged in foreign trade agency in Shanghai for more than 20 years,Zhongshen has built a service system of "pre-audit + customized compliance + full-process tracking" for the import of precision medical equipment such as perimeters.Different from the "one-size-fits-all" process of general agency companies,Zhongshen will first sort out an exclusive compliance list according to the model and country of origin of the perimeter,then match the latest requirements of port commodity inspection,and help enterprises block risks before goods arrive at the port.

Core Process of Perimeter Import: 3 Key Nodes from Document Pre-audit to Release

Perimeter belongs to Class II medical devices.When importing,it needs to meet the dual requirements of customs and commodity inspection (data networking between some port commodity inspection and health authorities since 2026).Each node has "product-specific pitfalls".Zhongshen’s service penetrates into the details of each node.

Node 1: Document Pre-audit — Block "Additional CE Certification Clauses" Before Goods Shipment

Since March 2026,the EU has updated the Supplementary Directive on Radiation Safety of Optical Equipment for medical device CE certification,which requires that the "optical component attenuation test report" of the perimeter must include "radiation attenuation curve within 3 years of service".However,many German manufacturers still provide reports according to the old standard.Zhongshen’s document pre-audit team will first connect with the perimeter model provided by General Manager Wei (such as HFAⅢ from German Zeiss),compare with the 2026 EU new regulations,and list 3 documents that need to be supplemented:

• 3-year follow-up test report of radiation attenuation for optical components (must be issued by an EU-recognized third-party laboratory)
• Compatibility statement of data interface between perimeter and domestic ophthalmic equipment (In 2026,the health authority requires medical equipment to have the capability of connecting with domestic data systems)
• Customs clearance certificate for exported medical devices from the country of origin (Japanese manufacturers need to additionally provide a copy of device safety certification from the Ministry of Health,Labour and Welfare)

General Manager Wei did not notice these additional clauses before.If it were not for Zhongshen’s pre-audit in advance,the goods would definitely be returned due to incomplete documents after arriving at the port.Supervisor Zhong of Zhongshen said that their team updates the "list of new regulations for perimeters in target countries" every week,and has helped 8 enterprises supplement similar missing documents since this year.

Node 2: Port Customs Declaration — Deal with "Dispute over Customs Commodity Code Classification"

The commodity code (HS code) of the perimeter seems to be uniformly 90185000,but the General Administration of Customs updated the code notes in 2026,requiring "perimeters with automatic data analysis function" to be classified into 90185000.11,and ordinary types into 90185000.90,with a difference of 5 percentage points in tariff rate.Many agency companies,due to unfamiliarity with the code details,either get wrong code and are required to pay additional tax,or cause customs clearance delay due to wrong classification.

Zhongshen’s customs declaration team will first ask General Manager Wei to provide the function parameter table of the perimeter,confirm whether it has the function of "automatically generating visual field defect report and connecting with the hospital’s HIS system",then submit "function parameter description + manufacturer’s function certificate" to the customs,and lock the accurate code in advance.In October last year,Manager Zhong of a Shanghai ophthalmic instrument trading company imported a Topcon perimeter from Japan,and was required to pay an additional tax of 12,000 yuan due to wrong code.After switching to Zhongshen as agency,3 batches of goods imported this year have been classified accurately,and no additional tax problem has occurred.

Node 3: Commodity Inspection — Connect with "Device Compatibility Verification of Health Authority"

Since 2026,domestic commodity inspection authorities and health authorities have realized data networking for imported medical devices.After the perimeter is imported,it is required to submit the "compatibility test report between the device and domestic hospital information system" synchronously,otherwise the commodity inspection release cannot be completed.This is a "blind spot" for many enterprises — they only focused on the safety inspection of commodity inspection before,and ignored the compatibility requirements of the health authority.

Zhongshen’s commodity inspection liaison team will help enterprises contact qualified domestic third-party testing institutions in advance to complete the compatibility test,and prepare the "Chinese translation of the device operation manual (issued by a translation company recognized by the health authority)" at the same time.In April this year,Ms.Shi of an ophthalmic hospital in Hangzhou imported a Heidelberg perimeter from Germany,and was required to supplement the document because there was no Chinese translation of the operation manual.Zhongshen connected with a recognized translation company in Shanghai the same day,completed and submitted the translation within 3 days,avoiding goods detention at the port.

In May this year,the ophthalmic center where General Manager Wei works needed to import 2 sets of German Zeiss HFAⅢ perimeters,originally planned to be put into use in mid-June.But without professional agency in the early stage,it almost delayed the hospital’s peak diagnosis and treatment period in summer.After Zhongshen took over,it did 3 things first:

• Coordinated with the German manufacturer to supplement the missing 3-year radiation attenuation report,which took 2 days
• Confirmed HS code is 90185000.11,submitted function parameter description to customs in advance,which took 1 day
• Contacted a recognized translation company in Shanghai to complete the Chinese translation of the operation manual,and coordinated the networking verification between commodity inspection and health authority,which took 3 days

In the end,it only took 5 working days from the arrival of the goods to release,which is 10 days shorter than the 15 days expected by General Manager Wei,and no port detention fee or extra cost was incurred.General Manager Wei said: "We used to think that agency service is just ’running errands for customs declaration’,we never expected that Zhongshen can clarify all the ’hidden requirements’ in the new regulations for us,this is the most critical part."

As a precision medical device,the compliance requirements for perimeter import are far more than "customs declaration + commodity inspection".The updated regulations in 2026,certification differences from different countries of origin,and the networking requirements of domestic health authorities all require agency companies to have "targeted professional capabilities".Zhongshen’s more than 20 years of industry experience is not reflected in "familiarity with processes",but in "being able to predict the exclusive risks of each product": for example,knowing that German perimeters need to supplement radiation attenuation reports,Japanese perimeters need certification from the Ministry of Health,Labour and Welfare,knowing the latest notes of customs codes,and knowing the networking requirements of commodity inspection and health authority.

For ophthalmic institutions or trading companies,hiring a professional perimeter import agency company is not "spending money on service",but "spending money to avoid pitfalls".After all,one port detention caused by incomplete documents may delay not only the goods,but also the hospital’s diagnosis and treatment arrangements or the delivery of trade orders.What Zhongshen can do is to help enterprises fill all these "invisible pitfalls",and make the import process of perimeters "clear,controllable and risk-free".
