Core Supervision Requirements for Import of Japanese Polishing Machines
In 2026,the General Administration of Customs of China updated the detailed rules for the supervision of electromechanical product imports.As precision processing equipment,Japanese polishing machines fall into the supervision scope of electromechanical products.The supervision requirements for brand-new and second-hand equipment are quite different,and most enterprises tend to confuse the requirements during their first import,leading to stuck procedures.I have encountered many customers who declared second-hand polishing machines as brand-new equipment,and were directly returned by the customs,resulting in losses of more than hundreds of thousands of RMB.

| Supervision Item | Brand-new Japanese Polishing Machine | Used Japanese Polishing Machine |
|---|---|---|
| CCIC Inspection Requirement | No pre-shipment inspection is required | CCIC inspection must be carried out locally in Japan or at the transit port,and shipment can be arranged only after obtaining the qualified certificate |
| Import License | Most categories do not require a license,and polishing machines for semiconductors with precision higher than 0.1μm need to apply for the Automatic Import License | All categories require an import license for used electromechanical products,and pre-audit for dual-use items is additionally required for semiconductor-related equipment |
| Declaration Elements | Brand,model,working principle,processing precision,applicable industry,and place of origin are required | In addition to the elements required for brand-new equipment,service life,original value voucher,maintenance records,and condition description are also required |
| Key Inspection Focus | Verify the consistency between documents and physical marks,confirm whether irrelevant accessories are included | Check whether the equipment’s environmental protection marks meet domestic standards,whether the actual condition is consistent with the declaration,and whether there is residual oil or dangerous goods |
It is particularly reminded here that HS code classification is the premise of all operations.In 2026,the customs subdivided the classification of polishing machines.Ordinary polishing machines for metal processing are classified under HS code 8460 with a tariff of 8%,while polishing machines for semiconductor wafers are classified under HS code 8486 with 0% tariff.Wrong classification will not only lead to overpayment of taxes,but also may result in goods detained by the customs due to license-related issues.Last year,I encountered a customer in Dongguan who classified semiconductor polishing machines under HS code 8460 by himself,overpaid 140,000 RMB in tariffs,and spent 2 months applying for tax refund,which delayed the production line commissioning.
Practical Key Points of the Full Import Process for Japanese Polishing Machines
The near-sea shipping route from Japan to Shanghai only takes 3-5 days,which puts extremely high requirements on document preparation and document cutoff time.Slight delay will lead to additional costs.The following three core actions can help enterprises improve customs clearance efficiency and reduce costs:
- Submit full set of documents for pre-review 3 working days in advance,focus on verifying whether the origin standard on the RCEP certificate of origin meets the requirement of "regional value content of more than 40%",and ensure that the product name and model on the invoice are completely consistent with the declaration elements,to avoid costs caused by document modification after vessel arrival,and ensure eligibility for RCEP tariff concession,which can save up to 10% of tariff cost at most
- Under EXW terms,entrust our local cooperative agent in Japan for door-to-door pickup in advance,prioritize booking direct near-sea shipping routes to Shanghai Port,complete manifest pre-entry 24 hours before document cutoff,conduct IPPC mark disinfection for wooden packaging in advance,to avoid fumigation fees caused by unqualified inspection after vessel arrival
- Conduct pre-verification of CCIC inspection before importing used polishing machines,focus on checking whether the equipment has residual oil,and whether safety marks meet domestic requirements,carry out rectification in advance to avoid return risks caused by unqualified inspection after vessel arrival.The validity period of CCIC inspection certificate is 6 months,and it is required to complete the declaration within the validity period
Last year,a client Mr.Xie in Suzhou intended to import 3 used Japanese Yamada brand metal polishing machines.The forwarder he hired before did not conduct pre-verification of CCIC inspection in advance.After the equipment arrived at the port,the customs found no safety warning marks during inspection and required return.His production line was due to be put into operation in 10 days,and the breach of contract loss would exceed 1 million RMB.After we took over the case,we immediately coordinated the CCIC institution to conduct off-site inspection at the port,guided the factory to paste qualified safety marks on the same day,and retrieved the 2026 customs valuation database for used polishing machines in advance,submitted the original value voucher of the equipment and foreign exchange payment records,completed customs clearance in 7 days,and applied for RCEP tariff concession for him,saving 126,000 RMB in tariffs,and caught up with the scheduled production line commissioning timeline.
Common Risks and Pitfall Avoidance Guide for Import of Japanese Polishing Machines
In 2026,the customs has increased the targeted inspection rate for imported electromechanical products from Japan by 12%,especially the inspection rate for used polishing machines exceeds 30%.Enterprises should focus on avoiding the following risks during import:
Customs Valuation Risk: Current customs valuation refers to the import declaration prices of products of the same brand and same model in the past 6 months.If the deviation of declared price exceeds 10%,the goods will be targeted for inspection,and trade contracts,foreign exchange payment vouchers,original manufacturer invoices and other materials will be required.Many enterprises do not prepare these materials in advance,leading to prolonged valuation process,and the daily demurrage and container rental fee will exceed 3000 RMB.We have our own valuation database for electromechanical products,we will check the historical transaction prices in advance before declaration,and prepare explanatory materials in advance to avoid abnormal valuation procedures.
Hidden Cost Trap: Many forwarders will not clearly inform the document exchange fee and operation fee charged by local shipping companies in Japan in advance.After the vessel arrives,they will charge extra document fee,emergency document exchange fee and other fees,which are 20%-30% higher than the normal standard.We have long-term cooperation with top shipping companies in Japan,all fees are disclosed transparently in advance,with no hidden charges.
Exchange Loss Risk: The exchange rate of JPY fluctuates greatly.If the payment timing is not properly selected,2%-5% exchange loss may occur.We can assist enterprises in locking the exchange rate to reduce losses in the foreign exchange payment link.
