Full Process Analysis and Precautions for Import Cargo Customs Clearance and Transportation

As an international shipping hub,Shanghai’s import cargo throughput hit a new high in 2026,but many enterprises have encountered setbacks in customs clearance and transportation.Last year,Mr.Deng imported mechanical equipment from Europe,which was delayed for 10 days due to incomplete customs clearance documents,directly affecting the commissioning of his production line.Ms.Gan paid more than RMB 20,000 extra for imported cosmetics due to incorrect tariff calculation.It can be seen that import cargo customs clearance and transportation is not a simple combination of delivery and customs declaration.It connects multiple nodes such as international transportation,port inspection,and tariff payment.Any omission in any link may lead to increased costs and delayed timelines.Next,we will systematically sort out the core procedures of customs clearance and transportation,as well as the professional support provided by Zhongshen in each link.

I.Core Procedure Breakdown of Import Cargo Customs Clearance and Transportation

Phase 1: Pre-preparation - Goal of Complete and Accurate Documentation

The key of this phase is to confirm cargo information and prepare compliant documents to avoid application rejection due to document issues.

Key Actions:

• 1.Confirm cargo HS Code: Accurate classification shall be carried out based on product material and function.HS Codes for some new energy equipment were updated in 2026,so attention shall be paid to the latest policies;
• 2.Prepare documents: Including bill of lading,invoice,packing list,contract,certificate of origin (for preferential tariff application),CCC certification (if required),etc.;
• 3.Confirm transportation mode: Choose among sea freight,air freight and land freight,and select appropriate routes and shipping space.Shanghai Yangshan Port added new direct routes to Southeast Asia in 2026,which can shorten transportation time by 2 days.

Common Problems:

• • Mismatched documents: For example,the invoice amount is inconsistent with the contract,or the manufacturer stated on the certificate of origin does not match the actual one;
• • Incorrect HS Code classification: Leads to wrong application of tariff rates,or cargo detention during customs inspection.

Zhongshen’s Support: Mr.Meng’s team at Zhongshen will review all documents in advance.In response to 2026 policy updates,we provide free HS Code verification for clients,and can also assist in handling certificate of origin and CCC certification to avoid delays caused by document issues.For example,the trading company run by Mr.Xiang had its HS Code adjusted correctly after review by Zhongshen last year,reducing tariff costs by 15%.

Phase 2: International Transportation - Goal of Controllable Timelines and Reasonable Costs

The transportation link needs to connect the port of departure and the port of destination.The global shipping space shortage has eased in 2026,but some routes still experience fluctuations,so shipping space needs to be locked in advance.

Key Actions:

• 1.Booking: Choose FCL or LCL according to cargo volume.LCL prices in 2026 are 8% lower than in 2025,which is suitable for small-batch cargo;
• 2.Track transportation status: Monitor cargo location in real time to avoid delays caused by bad weather and port congestion;
• 3.Prepare document exchange materials: After the sea freight bill of lading arrives at the port,the delivery order needs to be exchanged with the bill of lading,while for air freight,cargo is picked up with the air waybill.

Common Problems:

• • Shipping space cancellation: Some shipping companies temporarily cancel shipping space due to route adjustment,leading to cargo detention at the port of departure;
• • Damage during transportation: For example,fragile goods are not properly packed,leading to cargo damage.

Zhongshen’s Support: Zhongshen has long-term cooperation with more than 20 shipping companies and airlines,and can lock shipping space in advance.In the first half of 2026,we helped more than 30 clients avoid shipping space cancellation issues.At the same time,the team will provide packaging suggestions based on cargo characteristics.For example,Mr.Liao once assisted a client in arranging constant temperature containers for red wine cargo,reducing damage rate by 30%.

Phase 3: Port Customs Clearance - Goal of Fast Clearance and Compliant Inspection

This is the core link of customs clearance,involving customs declaration,inspection,tariff payment,etc.Shanghai Customs launched the "Smart Inspection" system in 2026,but declaration specifications still need to be strictly followed.

Key Actions:

• 1.Electronic declaration: Submit declaration data through the Single Window,and ensure data accuracy;
• 2.Customs inspection: If selected for inspection,cooperate with customs for unpacking inspection.The inspection rate is about 12% in 2026;
• 3.Tariff payment: Calculate customs duty,value-added tax and consumption tax based on HS Code,and cargo will be released after timely payment.

Common Problems:

• • Incorrect declaration data: For example,wrong cargo value or quantity leads to customs application rejection;
• • Inspection mismatch: The actual cargo is inconsistent with the declaration information,such as different models and specifications.

Zhongshen’s Support: Zhongshen’s customs declaration team is familiar with Single Window operations,with a declaration accuracy rate of 99.5%,and no application rejection has occurred so far in 2026.If the cargo is selected for inspection,Mr.Meng will accompany the whole process and assist in sorting out the cargo to shorten inspection time.For example,when Mr.Deng’s cargo was inspected last year,Zhongshen completed inspection and release in only 2 hours,1.5 hours faster than the industry average.

Phase 4: Domestic Distribution - Goal of Accurate Delivery to Designated Location

After customs clearance and release,the cargo needs to be transported from the port to the client’s warehouse or designated location.Attention shall be paid to the compliance and timeliness of domestic transportation.

Key Actions:

• 1.Cargo pickup: Pick up cargo at the port/airport with the delivery order,and confirm the quantity and status of the cargo;
• 2.Domestic transportation: Select compliant logistics companies.For example,cold chain cargo requires constant temperature vehicles;
• 3.Sign for confirmation: The whole process is completed after the client signs for receipt.

Common Problems:

• • Delayed cargo pickup: Unable to pick up cargo in time due to port congestion or delayed arrival of documents;
• • Delivery error: For example,wrong address leads to cargo delivered to the wrong location.

Zhongshen’s Support: Zhongshen cooperates with multiple local logistics companies in Shanghai,and can arrange priority cargo pickup.The average pickup time in 2026 is 1 day faster than the industry average.At the same time,the team will repeatedly check the delivery address to ensure accurate delivery of cargo.For example,for Ms.Gan’s cosmetics cargo,Zhongshen arranged special personnel to track the delivery,and the cargo was delivered to the warehouse on the same day without damage.

From pre-preparation to domestic distribution,each link of import cargo customs clearance and transportation is closely connected.Any omission may affect the supply chain efficiency of enterprises.Although self-handling seems to save money,the rapid policy updates and complex procedures in 2026 make it easy to cause delays and additional costs due to insufficient experience.Zhongshen has been deeply engaged in the industry for more than 20 years,and is familiar with the operation specifications and latest policies of Shanghai ports.We can help clients avoid risks and improve efficiency in each link.For example,after choosing Zhongshen’s agency service,Mr.Xiang’s company shortened customs clearance time by 40% and saved more than RMB 100,000 in annual costs.
