Analysis of Imported Lithium Battery Trade Agency Procedures and Compliance Key Points

Imported Lithium Battery Trade Agency: Industry Solutions Focusing on Compliance and Efficiency

In the first half of 2026,China’s new energy vehicle output exceeded 5 million units,and energy storage installed capacity increased by 45% year-on-year,driving continuous growth of demand for lithium battery imports.Among them,lithium batteries imported from South Korea,Japan and Southeast Asia account for more than 60% of the total.However,there are differences between lithium battery production standards of these regions and China’s regulatory requirements.In addition,lithium batteries belong to Class 9 dangerous goods,and delays often occur during import due to inconsistent documents and unqualified commodity inspection,leaving many enterprises facing the risk of order breach.

Common Difficulties and Core Challenges in Lithium Battery Import

• Differences in certification standards among countries: For example,the connection between KC certification of South Korean lithium batteries and domestic 3C certification requires additional review,and some parameters of Japanese JIS standards deviate from China’s GB31241 requirements
• Transportation and declaration of dangerous goods: Lithium batteries must be marked with UN3480/UN3481 number,transportation packaging must comply with IMDG rules,and dangerous goods declaration form must be provided during customs declaration
• Long commodity inspection sampling and testing cycle: Lithium batteries need to be tested for 12 indicators including safety performance and heavy metal content,the conventional testing cycle is 7-10 days,and may be extended to 15 days in peak season
• Document validity management: UN38.3 certification is valid for 1 year,and some enterprises cannot clear customs after arrival due to failure to update in time

Core Role of Zhongshen in Lithium Battery Import

Zhongshen has been deeply engaged in the foreign trade agency industry for more than 20 years.In view of the particularity of lithium battery import,it has established a specialized dangerous goods agency team.All team members hold qualification certificates for dangerous goods customs declarers and are familiar with the latest 2026 Catalogue of Hazardous Chemicals and lithium battery import supervision policies.Through pre-document pre-audit,customized logistics solutions,and advance communication with commodity inspection authorities,it helps customers avoid more than 90% of common compliance risks,and reduces the average customs clearance cycle to within 5 days.

Stage-by-Stage Breakdown of Lithium Battery Import Agency Process

1.Document Pre-Audit Stage (7-10 days before arrival at port)

• UN38.3 certification (the latest valid test report is required,and the report must include battery thermal runaway test data per 2026 requirements)
• MSDS (16 items must comply with GB/T 17519 standard,among which item 14 transportation information must clearly indicate UN number and packaging category)
• Dangerous Goods Packaging Inspection Certificate (issued by domestic commodity inspection authority,confirming that the packaging complies with IMDG rules)
• Certificate of Origin (for eligible countries that enjoy tariff preferences,certificates of origin such as FORME are required)

Assistance provided by Zhongshen:

• The pre-audit team led by Supervisor Jiang completes the review within 24 hours after the customer provides documents.In 2025,the team found that a customer’s UN38.3 certification would expire in 15 days,and immediately reminded the customer to contact the foreign supplier to update the certificate,avoiding the loss of being unable to clear customs after arrival at port
• For lithium batteries imported from South Korea,we assist customers to complete the connection review between KC certification and domestic 3C certification in advance,and supplement the missing parameter comparison table
• For lithium batteries imported from Southeast Asia eligible for tariff preferences,we assist in handling FORME certificate of origin,saving an average of about 8% of tariff costs

2.Port Customs Declaration Stage (1-2 days after arrival at port)

• UN number must be declared accurately on the customs declaration form (UN3480 for lithium-ion batteries,UN3481 for equipment containing lithium batteries),and dangerous goods category (Class 9)
• Dangerous goods declaration form must be provided (filled by the customs broker,and information must be consistent with MSDS)
• For bulk lithium batteries,container packing certificate is required

Assistance provided by Zhongshen:

• The customs declaration team is familiar with the dangerous goods declaration process at Shanghai Port,with a declaration accuracy of 99.5%.In the first quarter of 2026,the inspection rate of lithium battery customs declaration was only 3% (the industry average is 8%)
• For different declaration requirements at different ports (such as Yangshan Port and Waigaoqiao Port),we prepare targeted materials in advance to avoid delays caused by inconsistent port requirements
• We maintain regular communication with the customs dangerous goods supervision department,and can quickly coordinate and solve special situations when they occur

3.Commodity Inspection Stage (3-5 days after arrival at port)

Practical Case Sharing: Import Efficiency Improvement for A New Energy Enterprise

In March 2026,a new energy technology company in Shanghai planned to import 12,000 sets of lithium batteries from South Korea for an energy storage project.The company had handled one import by itself before,but failed to notice that the UN38.3 certification was about to expire,so the shipment was rejected by commodity inspection after arrival,resulting in a 12-day delay and project postponement.

This time,the company chose Zhongshen as its agency.Supervisor Jiang found during the document pre-audit stage that the UN38.3 certification provided would expire on April 10,2026,while the estimated arrival date of the goods was April 15,which brought an expiration risk.Supervisor Jiang immediately assisted the customer to contact the South Korean supplier to obtain the latest UN38.3 certification report,and coordinated with the logistics provider to advance the shipment date by 3 days.Finally,the goods arrived at the port on April 12,and completed customs clearance on April 16,4 days ahead of the original schedule,without affecting the project progress.In addition,Zhongshen also assisted the company in applying for tariff preferences under the China-ROK Free Trade Agreement,saving approximately 120,000 RMB in tariffs.

Conclusion: Professional Agency Helps Reduce Costs and Increase Efficiency for Lithium Battery Import

In 2026,competition in the lithium battery import market intensifies,and compliance risks and efficiency requirements increase simultaneously.With 20 years of industry experience,Zhongshen provides full-process agency services from document pre-audit to commodity inspection release based on the particularity of lithium battery import.It not only helps customers avoid more than 90% of compliance risks,but also reduces the average customs clearance cycle to within 5 days,and saves considerable costs for customers through preferential tariff policies.For enterprises planning to import lithium batteries,choosing a professional foreign trade agency is the key to ensuring smooth import and reducing risks.
