Kunshan Import Customs Clearance Agency: Full Process Analysis from Preparation to Release

In 2026,Kunshan’s import business volume increased by 12% compared with 2025,with electronic components,mechanical equipment and chemical raw materials as the core import categories.Many Kunshan enterprises reported that delays often occur in the customs clearance link due to document errors and lagging policy updates,which affects production schedules.With over 20 years of experience in foreign trade agency services,Zhongshen focuses on the needs of local enterprises,sorts out the core procedures of import customs clearance agency,and helps enterprises avoid risks and improve efficiency.

I.Pre-import Preparation Stage: Consolidate Compliance Foundation to Avoid Subsequent Delays

Stage Objective: Ensure all import documents are complete and comply with the latest 2026 policy requirements,and avoid compliance risks in advance.

Key Actions:

• Verify HS Code of imported goods: Tariff codes for some electronic chips and new energy materials were adjusted in 2026,so accurate classification is required
• Apply for import license/quota: such as CCC Certification,Automatic Import License (for mechanical and electrical products),Endangered Species Import Permit (if required)
• Inspection and quarantine filing: Some food,cosmetics and medical devices need to complete filing with Kunshan Bureau of Entry-Exit Inspection and Quarantine in advance
• Sign agency agreement: Clarify responsibilities of both parties,and specify customs clearance time limit and detailed fee structure

Common Problems:

1.Incorrect HS Code classification: When the Kunshan electronics factory where Mr.Li works imported South Korean chips in 2026,they filed the declaration with an incorrect code on their own,resulting in 3% overpayment of customs duty,with an extra cost of about RMB 21,000 for a single batch of goods.

2.Failure to apply for license in advance: When Mr.Kong imported German machine tools,he was not aware of the new 2026 requirements for import license of mechanical and electrical products,so declaration could not be processed after the goods arrived at the port,and the accumulated container detention fee exceeded RMB 3,000 at RMB 1,000 per day.

Zhongshen’s Advantages:

• We have 5 commodity classification specialists certified by the General Administration of Customs of China.Internal training was completed within 3 days after the 2026 new tariff regulation update,ensuring HS Code classification accuracy of over 99%;

• Electronic declaration: Submit customs declaration form through the newly launched "Smart Customs Clearance System" of Kunshan Customs
• Tax payment: Assist enterprises to pay customs duty and value-added tax (VAT,if required) through the customs electronic payment system

Common Problems:

1.Manifest error: Some freight forwarders have system delays,resulting in inconsistency between manifest information and actual goods,which takes 3-5 working days to modify;

2.Declaration data deviation: For example,incorrect filling of goods value leads to customs questioning the authenticity of the trade,triggering manual review.

Zhongshen’s Advantages:

• We have established a pre-verification mechanism for manifests with the top 10 shipping companies operating in Kunshan.Manifest information is confirmed 12 hours before the goods arrive at the port,and any errors found will be corrected immediately after contact;

III.Inspection and Release Stage: Cooperate Efficiently to Reduce Detention Time

Stage Objective: Pass customs inspection smoothly,complete release within 48 hours,and avoid container detention and port demurrage.

Key Actions:

• Inspection preparation: Sort out detailed goods information (such as certificate of origin,quality test report)
• Accompany inspection: If the customs requires unpacking inspection,arrange dedicated staff to cooperate on site
• Release confirmation: After receiving the customs release instruction,notify the container yard/warehouse to release the goods

Common Problems:

1.Overlong inspection time: Some enterprises have incomplete materials,so the inspection time is extended from 24 hours to 72 hours;

2.Inconsistent goods: For example,the declared goods are "electronic components" but the actual goods are "second-hand equipment",which triggers cargo detention.

Zhongshen’s Advantages:

• We have 3 specialists with more than 10 years of customs inspection experience,who sort out inspection materials in advance,shortening the average inspection time to 12 hours;

IV.Post-release Procedure Stage: Complete the Closed Loop to Ensure Smooth Goods Pick-up

Stage Objective: Complete the processing of delivery order within 1 working day,and verify the customs declaration form simultaneously to ensure smooth foreign exchange receipt and payment.

Key Actions:

• Process delivery order: Exchange for delivery order at the container yard/warehouse with the customs release instruction
• Domestic transportation: Arrange compliant logistics vehicles if door-to-door service is required
• Customs declaration verification: Assist enterprises to verify import customs declaration forms with the State Administration of Foreign Exchange (SAFE)

Common Problems:

1.Delivery order delay: Due to queuing at some container yards,processing of delivery order takes 2 working days;
