Caption: Used equipment import requires a valid CCIC Pre-Shipment Inspection Certificate; all critical details must match perfectly across customs documents and equipment nameplates

Two types of import licenses apply:

Automatic Import License (O License): Mandatory for most used electromechanical equipment. Applications are submitted via the Single Window Platform of the Ministry of Commerce, with approval taking 5–7 working days.

License for Key Used Mechanical and Electrical Products: Required for heavy-duty machine tools, construction machinery and specified equipment. Approval takes roughly 21 working days and demands supplementary technical documentation and usage statements.

Most new equipment does not require import licenses, though high-tech or national security-related machinery still needs permit approval.

Mandatory baseline documents include sales contracts, commercial invoices (used equipment invoices must clearly state "second-hand", alongside original value, depreciation rate and service life), packing lists, ocean bills of lading, and certificates of origin (for preferential tariff eligibility). Additional paperwork for used equipment includes nameplate photos, technical manuals, original commercial invoices or third-party appraisal reports to support customs valuation. Wooden packaging must display valid IPPC marks and fumigation certificates.

Thorough pre-work streamlines subsequent clearance; insufficient pre-prep triggers endless corrective measures and delays.

03 End-to-End Import Workflow for Assembly Line Equipment

Step 1: HS Coding & Customs Control Verification

Classify each machine against HS codes one by one, confirming tariff rates, regulatory controls and special permit obligations. For new equipment, prioritize CCC certification checks; for used equipment, confirm exclusion from the Prohibited Import Catalogue for Used Mechanical and Electrical Products.

Step 2: Pre-Shipment Inspection (Exclusive to Used Equipment)

Engage CCIC 15–30 days before scheduled shipment for inspections covering safety protection, environmental compliance and nameplate matching. Passing inspection yields the Certificate of Pre-Shipment Inspection for Imported Used Mechanical and Electrical Products.

Step 3: Import License Application

For used equipment requiring O Licenses, submit CCIC pre-review results, contracts, invoices and supporting materials via the Single Window portal. Key used machinery applications require extra technical paperwork and longer lead times. All licenses should be secured before cargo departs overseas.

Step 4: International Shipping & Cargo Arrival

Select container types based on equipment dimensions and weight:

20GP: small-to-medium machinery

40HQ: medium-sized equipment

Flat rack/open-top containers: extra-wide/extra-tall oversized cargo

Precision machinery is packed with vacuum wrapping plus desiccants for humidity control; heavy equipment is secured inside containers with wooden bracing and lashing straps. Ocean transit takes 25–35 days from Europe to China, and 5–10 days from Japan to China.

Step 5: Terminal Document Exchange & Electronic Customs Declaration

Exchange bills of lading for delivery orders with the shipping carrier, then submit customs and inspection declaration data plus full document packages through the International Trade Single Window. Declared elements include brand, model, manufacturing year, function, application and quantity; used shipments must be marked "used mechanical and electrical goods".

Step 6: Customs Valuation & Physical Inspection

Customs verifies the reasonableness of declared transaction value. Used equipment undergoes rigorous valuation audits. If the declared price falls drastically below market benchmarks, Customs initiates price negotiation, requiring supporting evidence such as original invoices and foreign exchange payment vouchers. Physical inspection cross-checks physical goods against declarations, focusing on model, production year and nameplate consistency. For used machinery, inspectors also check for oil leaks and potential safety hazards.

Step 7: Tax Payment, Customs Release & Cargo Pickup

Customs issues tax notifications post-valuation approval. Goods are released after importers settle applicable customs duties and VAT. Certain categories of used equipment require domestic destination inspection: cargo is transported to the designated domestic site, where local Customs conducts unpacked examinations and even power-on testing. Goods can only enter formal production after passing safety and environmental compliance verification.

Clearance Lead Time Reference

New equipment with no inspection: 3–5 working days; with inspection: 5–7 working days

Used equipment: stricter valuation and inspection extend total clearance to 7–15 working days

Every step has fixed timelines; delays in one phase push back all subsequent procedures.

04 Common Questions & Risk Avoidance Guide

Q: What are the import tariff rates for assembly line equipment?

A: Tariffs are determined by equipment type and corresponding HS code. CNC lathes attract 5%–9% duties, machining centers 5%–7%, industrial robots 0%–5%, and testing equipment 5%–10%. A uniform 13% VAT applies to all imports. Final rates are subject to the latest official Customs Tariff Schedule tied to each HS code.

Q: What core differences exist between importing new versus used equipment?

A: Used equipment mandates CCIC pre-shipment inspection plus O Licenses/key used machinery permits, faces far stricter customs valuation, and may require domestic destination inspection. New equipment generally skips these procedures, enabling faster clearance, though CCC certification may still apply to certain models.

Q: What consequences arise from incorrect HS classification?

A: Minor cases require amendment declarations and supplementary tariff payments with nominal amendment fees. Severe misclassification is deemed false declaration, triggering back payment of owed taxes plus fines equivalent to 30%–50% of underpaid duties. Serious violations are referred to Customs Anti-Smuggling departments. For ambiguous coding scenarios, apply to Customs in advance for official pre-classification rulings.

Q: Can CCIC inspection be completed after cargo arrives at port if omitted pre-shipment?

A: No retroactive inspection is allowed. CCIC pre-shipment inspection must be completed in the exporting country or Hong Kong before cargo departs. The only remedy is returning goods to the origin country or transshipping to Hong Kong for inspection prior to re-import, incurring substantial round-trip freight and schedule losses.

Critical Reminder

Nameplate information (brand, model, production year, country of origin) on used equipment must match CCIC certificates and customs documents word-for-word. Information discrepancy ranks top among reasons for forced cargo return.

05 Import Expertise from GOOWELL International Logistics

We boast extensive hands-on experience in machinery import and export, supporting imports of CNC machine tools, machining centers, complete production lines, precision instruments and more.

End-to-end project coordination defines successful assembly line import. An integrated line may source machinery across multiple countries and vendors with staggered arrival times, varied HS codes and mixed new/used units. GOOWELL devises customized import roadmaps for each production line, including unified HS classification, phased CCIC scheduling, coordinated port arrival timelines and consolidated customs filings. This avoids excessive warehousing and detention fees caused by scattered shipments.

For packaging and transportation, precision equipment receives customized shockproof vacuum moisture-proof packaging; oversized heavy machinery uses tailor-made flat rack container solutions, with overland oversize permits secured ahead of domestic haulage. Mainstream ocean carriers including COSCO Shipping and Maersk are our long-term partners. Our overseas agency network in Europe, Japan, South Korea and major equipment-exporting regions enables complete door-to-door logistics covering overseas factory collection through domestic factory handover.

Our customs brokerage team fully understands valuation audit criteria for industrial machinery and compiles supporting valuation materials in advance to minimize price negotiation risks with Customs.

Equipment import management begins at contract signing rather than merely cargo portage.
