What Are the Key Steps in Purification Equipment Import Agency?

Entry Barriers and Regulatory Red Lines for Purification Equipment Import AgencyThe core challenges of purification equipment import agency lie in **regulatory compliance** and **process coordination**.Taking medical-grade air purification equipment as an example,in the updated 2026 General Administration of Customs’ <em>List of Commodities Subject to Statutory Inspection</em>,some purification equipment is classified as "electrical equipment for medical use," requiring an additional Medical Device Registration Certificate.A key detail here: if during declaration,"industrial-grade air purifiers" (HS code 84142000) are mistakenly confused with "medical purification equipment" (HS code 90191000),it can trigger customs inspection at best,or lead to direct return of goods due to missing CCC certification at worst.Zhongshitong once encountered a case involving the import of a German laboratory clean bench: the client failed to complete the **pre-import filing for used mechanical and electrical products** in advance.After the goods arrived at the port,they were detained by customs for not submitting the <em>Pre-shipment Inspection Certificate for Imported Used Mechanical and Electrical Products</em> (commonly known as the "China Inspection Certificate").Demurrage fees reached 800 yuan per day.The clearance was finally completed within 5 working days only through an emergency application of a "special case,special handling" process.This reminds us: regardless of whether the equipment is new or used,**it must be confirmed before import whether it falls under the "used mechanical and electrical products" category** to avoid additional costs due to missing filings.### Core Regulatory Red Line Checklist<ul>- **3C Compulsory Certification**: Starting from 2026,medical purification equipment (e.g.operating room laminar flow purification systems) mandatorily requires a CCC certificate.For civilian air purifiers exported from the EU/US,additional verification of CE/FCC certification is needed.- **Statutory Inspection List Verification**: If purification equipment contains filter materials (e.g.HEPA filters),it must be confirmed whether it belongs to the "filter membrane/filter element" category of statutory inspection commodities.The specific material composition must be indicated during declaration.- **Rules of Origin**: For equipment imported from RCEP member countries applying for tariff reduction,the Certificate of Origin must meet the "Regional Value Content ≥ 30%" requirement and must complete electronic seal filing before import.## Complete Breakdown of Purification Equipment Clearance Process at Shanghai PortAs a seasoned agent at the Shanghai port,we break down the purification equipment import process into 4 key stages,each with standardized operating procedures (SOP).Taking a semiconductor company’s import of a Japanese wafer clean bench as an example,the core steps are as follows:

Stage	Key Operational Points	Common Risk Points	Response Strategy
1.Pre-review Stage	Verify HS code (e.g.94062010/90248990),CCC certificate number,validity of Certificate of Origin	HS code classification error (e.g.misclassification under 94059090 leading to exemption from 3C review)	Engage an engineer 7 working days in advance for on-site confirmation of equipment parameters (air speed/purification level/noise level)
2.Inspection Declaration Stage	Submit Application for Inspection of Imported Goods,China Inspection Certificate (if involving used equipment),Import Medical Device Registration Certificate	Information on the Medical Device Registration Certificate does not match the product nameplate	Request foreign suppliers to provide the latest version of the registration certificate (new "purification efficiency decay cycle" parameter added from 2026)
3.Customs Declaration Stage	Adopt the "two-step declaration" model: declare basic information first,then supplement price supporting documents	Valuation dispute (e.g.deviation between the equipment’s FOB price and the customs database reference price exceeds 15%)	Prepare a "Price Explanation Letter" in advance,highlighting equipment depreciation period and allocation ratio of technical patent fees
4.Release Stage	Complete inspection (key checks: 1.Whether the actual goods match the declared model; 2.Whether the CCC certification is valid)	Inspection reveals "model and parameter mismatch" (e.g.declared Model A,actual is upgraded Model A1)	Notify the Commodity Inspection Bureau 3 days in advance for on-site inspection and simultaneously submit a "Declaration of Equipment Parameter Consistency"

### Special Policies at Shanghai Port in 2026As one of China’s first "Cross-border E-commerce Retail Import Pilot Cities," Shanghai offers the **"Inspect Before Release"** policy for purification equipment imports,subject to two conditions: ① The declared goods have completed classification confirmation; ② The importer/exporter’s credit rating is Class A.Through this policy in the past 3 months,Zhongshitong has reduced the average clearance time from 5 days to 2.5 days,saving demurrage fees accounting for approximately 0.8% of the cargo value.## Three Practical Pitfall-Avoidance Solutions for High-Risk Purification Equipment Import Operations**Case 1: Cargo Detention Due to HS Code Classification Error**

A client imported a laboratory clean bench from the USA,declaring HS code 84143000 (industrial ventilation equipment).Customs inspection found it actually belonged to "medical purification equipment" (HS code 90191000),requiring supplementary CCC certification.Due to the lack of prior confirmation,the goods were detained at the port for 7 days,incurring 120,000 yuan in demurrage fees.**Solution**:

• Commission a third-party inspection agency (e.g.SGS) to issue an <em>Equipment Purpose Statement</em>,clearly defining "medical-grade" or "industrial-grade";
• Provide an equipment parameter sheet (including key indicators such as "Cleanliness Class ISO 5");
• Utilize Zhongshitong’s internal system to match against a database of similar equipment classification cases at Shanghai port from the past 12 months to reduce classification error rates.**Case 2: Missing Used Mechanical & Electrical Products Filing for Second-hand Purification Equipment**

A company imported a used German air purification unit without declaring the used mechanical and electrical products filing.It was identified by customs as a "prohibited import used mechanical and electrical product," facing the risk of return.**Solution**:

• Verify in advance the <em>Administrative Measures for Filing of Imported Used Mechanical and Electrical Products</em> (2026 adds "environmental indicator verification for used equipment" requirement);
• Require foreign suppliers to provide a <em>Proof of Equipment Service Life</em> (must indicate "used for less than 5 years");
• Adopt the "File First,Ship Later" model,with Zhongshitong tracking the filing progress throughout to ensure the <em>Pre-shipment Inspection Certificate for Imported Used Mechanical and Electrical Products</em> is completed before clearance.**Case 3: Tax Supplement Due to Valuation Dispute**

A client imported a biological safety cabinet with a declared FOB price of USD 100,000.The customs reference price was USD 92,000,triggering a "price query."**Solution**:

• Provide a "Price Supporting Document Package": including Certificate of Origin,Packing List,Foreign Purchase Contract,and Insurance Policy;
• Specifically highlight "Technical Patent Fees" (e.g.if the equipment contains 10 patents).According to the General Administration of Customs Announcement No.12 of 2026,patent fees can be listed separately and are not included in the dutiable value;
• Apply for a "Price Consultation." After communication with the customs classification department,the final dutiable value was set at USD 95,000,only USD 5,000 higher than the declared price,saving subsequent inspection costs.## 2026 Purification Equipment Import Policy Dynamics and ResponsesStarting January 2026,the implementation of the <em>Notice on Further Optimizing the Import Process for Cross-border Medical Equipment</em> brings the following main changes:
  • 3C Certification Simplification: Purification equipment meeting the "Low-Risk Directory" can apply for the "Self-Declaration" model,saving approximately 15 working days;
  • Integration of Inspection and Quarantine: The original "Animal and Plant Quarantine" and "Sanitary Quarantine" are merged into "Inspection and Quarantine of Imported Goods," eliminating the need for duplicate document submission during declaration;
  • Anti-dumping Early Warning: The EU’s anti-dumping duties on Chinese-origin HEPA filters are extended to 2027.It is necessary to confirm in advance that the origin is not an EU country.Zhongshitong’s Recommendations:
  • For equipment imported from Europe and the USA,prioritize "EXW terms" to avoid valuation disputes caused by incomplete price supporting documents provided by the seller;
  • For equipment imported from RCEP member countries (e.g.Japan,Australia),apply for the Certificate of Origin 3 months in advance and complete the "Regional Value Content" calculation;
  • For medical purification equipment,be sure to confirm the definition of "Class III Medical Device" in the <em>Regulations on Supervision and Administration of Medical Devices</em> (2026 revised edition) to avoid misjudgment of its applicable scope.## Value and Risk Warning for Purification Equipment Import AgencyChoosing a professional agency company,its core value is reflected in **proactive risk management** and **resource integration**.Taking Zhongshitong as an example,we have established a "Three-Dimensional Risk Control System":
• Technical Dimension: Equipped with over 5 engineers holding CMA qualifications for on-site verification of equipment parameters;
• Policy Dimension: Dedicated personnel track policy updates from the General Administration of Customs and the Medical Products Administration,issuing the monthly <em>Purification Equipment Import Policy Monthly Report</em>;
• Resource Dimension: Maintain green channel relationships with inspection departments at ports such as Shanghai Port,Pudong Airport,and Yangshan Port to shorten inspection waiting times.**Risk Warning Checklist**:
  • Prohibit using "generic" declarations (e.g."purification equipment" without specifying its specific purpose);
  • Prohibit ignoring the "validity period of CCC certification" (the "annual review" requirement is added from 2026);
  • Prohibit omitting the "equipment serial number" during declaration (customs adds a new "one machine,one code" traceability requirement in 2026).The essence of purification equipment import agency is the **implementation of compliant solutions**.In 2026,with the growth of cross-border medical trade,purification equipment imports are expected to increase by 12% year-on-year,but regulatory requirements are also becoming more refined.Choosing an agent like Zhongshitong,which possesses "20 years of port operational experience + nationwide remote declaration capability," is the true way to achieve "safely bringing global quality goods into China."
