Sorting out Core Links and Necessary Conditions for Import Customs Clearance

In 2026,the value of imported goods through Shanghai Port saw an 8.2% year-on-year increase.As a key node connecting international logistics and the domestic market,import customs clearance directly affects enterprises’ capital turnover and market timeliness.Many enterprises face additional detention fees due to unfamiliarity with clearance procedures and incomplete document preparation — in Q1 2026 alone,12.7% of imported goods through Shanghai Port were delayed due to document issues,with an average detention time of 4.5 days.Combining over 20 years of practical experience from Zhongshen,this article systematically sorts out the core links,necessary conditions and risk avoidance points for import customs clearance.

Decomposition of Core Stages of Import Customs Clearance

1.Pre-Clearance: Document Preparation and Compliance Verification (Goal: Avoid Declaration Rejection)

Document preparation before clearance is the foundation of the entire process.If documents are missing or do not meet the latest regulatory requirements in 2026,the declaration will be directly rejected by the customs,with a delay of usually 3-7 days.Key actions include: 1.Verify the consistency of bills of lading,commercial invoices,contracts and packing lists (e.g.goods names,quantities and amounts must fully match); 2.Apply for customs inspection clearance certificates (some goods such as food and cosmetics require pre-inspection); 3.Confirm the validity of the certificate of origin (the RCEP free trade agreement was updated in 2026,so the latest version and FTA code need to be checked).

Common issue: In 2026,a customer imported durian from Southeast Asia but could not enjoy tariff preferences (reduced from 15% to 0%) because the certificate of origin did not indicate the RCEP code.Director Luo from Zhongshen immediately assisted in supplementing the documents after discovering the issue,avoiding 120,000 RMB in tariff losses.

The role of Zhongshen in this stage: 1.Provide the latest customs clearance document list for 2026 (categorized by goods types,such as food,mechanical and electrical products,chemicals,etc.); 2.Review all documents 1-2 working days in advance to point out discrepancies such as goods name descriptions and declaration codes; 3.For special goods (such as medical devices),assist in coordinating with the customs inspection department for pre-inspection in advance to shorten the clearance cycle.

2.After Arrival: Declaration and Tax Payment (Goal: Complete Electronic Declaration and Tax Payment Quickly)

After the goods arrive at the port,electronic declaration must be completed within the specified time (generally within 14 days for Shanghai Port),otherwise detention fees will be incurred (about 150-300 RMB per container per day).Key actions include: 1.Submit declaration data through the China International Trade Single Window; 2.Verify the customs duty,VAT and consumption tax payment notices issued by the customs (VAT for some goods is deductible in 2026); 3.Pay taxes and fees on time (electronic payment methods are supported,such as bank guarantees and third-party payment platforms).

Common issue: Some enterprises paid excess tariffs because they were unaware of the 2026 tariff adjustment policies.For example,a customer imported new environmental protection building materials.Manager Nie from Zhongshen found in advance that this product is included in the Catalog of Encouraged Imported Technologies and Products,with the tariff reduced from 10% to 5%.After assisting in adjusting the declaration code,30% of the tax costs were saved.

The role of Zhongshen in this stage: 1.Assign dedicated personnel to handle declarations through the Single Window to ensure accurate data,with a declaration pass rate of over 98%; 2.Real-time query the latest tariff updates for 2026 and assist in selecting the optimal declaration code; 3.Provide tax payment agency services and support account settlement to avoid enterprises delaying clearance due to capital issues.

3.Inspection and Release: Risk Avoidance and Efficiency Improvement (Goal: Pass Inspection Smoothly and Release Quickly)

Customs inspection is a key link in customs clearance.In 2026,Shanghai Customs launched "smart inspection" (screening high-risk goods through AI image recognition),but some goods such as chemicals and food still require manual inspection.Key actions include: 1.Cooperate with customs inspection personnel to open containers for inspection (need to prepare goods lists and samples); 2.If problems are found during inspection (such as quantity differences,inconsistent packaging),supplement explanatory materials in a timely manner; 3.After passing the inspection,the customs will issue a release notice.

Common issue: A customer imported chemical raw materials and was required by the customs to rectify because there were no Chinese warning labels on the packaging.Ms.Shang from Zhongshen assisted in contacting the warehouse to reapply the labels,completing the rectification in only 1 day and avoiding goods re-exportation (re-exportation costs about 10% of the goods value).

The role of Zhongshen in this stage: 1.Predict high-risk goods (such as sensitive chemicals,food) in advance and assist in preparing materials required for inspection; 2.Arrange dedicated personnel to cooperate with inspection on-site and communicate with the customs in a timely manner to avoid repeated inspections; 3.Maintain close contact with the customs to understand the inspection progress in real time,with an average release time 2 days shorter than that of enterprises operating on their own.

4.Post-Clearance: Settlement and Verification (Goal: Complete the Customs Clearance Loop and Avoid Unresolved Issues)

After customs clearance and release,subsequent settlement and verification are required to ensure a complete process loop.Key actions include: 1.Pay customs clearance service fees,warehousing fees,transportation fees,etc.(need to verify the fee details); 2.Verify the import tariff payment notice (the verification period in 2026 is 180 days,and VAT cannot be deducted if overdue); 3.If foreign exchange receipt and payment are involved,complete foreign exchange verification through the State Administration of Foreign Exchange (SAFE) system.

Common issue: Some enterprises failed to deduct VAT because they did not verify the tariff payment notice in time,increasing costs by about 8%.Director Jin from Zhongshen reminded that in 2026,tariff payment notices can be verified online through the Single Window without submitting offline materials.

The role of Zhongshen in this stage: 1.Provide detailed fee lists with transparent pricing (no hidden fees); 2.Assist in handling the verification of tariff payment notices and set reminders to avoid overdue; 3.Coordinate with foreign exchange departments to complete foreign exchange receipt and payment and verification,ensuring safe arrival of funds (average arrival time is 3 days shorter than that of enterprises operating on their own).
