In the global trade landscape of lithium batteries, maritime shipping has become the mainstream choice for exporting most battery products due to its large shipping capacity and low cost. However, as Class 9 Dangerous Goods, the safety of lithium battery maritime transport has attracted widespread attention from the international community. An authoritative and compliant lithium battery maritime shipping appraisal report is not only a mandatory requirement of international regulations but also a statutory "pass" to ensure the safety of the entire shipment, avoid huge losses, and guarantee the smooth progress of trade.

Why is a Shipping Appraisal Report Mandatory for Lithium Battery Maritime Transport?

Mandatory Requirements of International Conventions and Domestic Regulations

According to the International Maritime Organization (IMO) International Maritime Dangerous Goods Code (IMDG Code), as well as China's Maritime Traffic Safety Law and Regulations on the Safety Supervision and Administration of Ships Carrying Dangerous Goods, a dangerous goods transport condition appraisal report issued by a qualified institution must be obtained before lithium batteries are delivered for maritime shipping. Shippers shall use this report to handle shipping procedures with carriers and declare to maritime administrative departments. Without a report or with an non-compliant report, the goods cannot be loaded and shipped.

Lifeline of Maritime Shipping Safety: Preventing "Ship Fire" Risks

Modern container ships have enormous cargo capacity. Once lithium batteries in a container experience thermal runaway due to defects, short circuits, or improper packaging, the fire may spread rapidly in the confined space, leading to catastrophic consequences. In recent years, there have been multiple container ship fire accidents suspected to be caused by lithium batteries. Through strict testing and evaluation of the batteries themselves and their packaging, the appraisal report maximizes the elimination of spontaneous combustion risks during transportation from the source, serving as a key technical document to ensure the safety of the entire ship's personnel, the vessel, and the cargo.

Cornerstone of Smooth Supply Chain and Trade Compliance

Shipping companies and their agents will strictly examine the appraisal report when accepting booking requests. Without a valid report, the goods cannot obtain shipping qualification. Meanwhile, customs and maritime bureaus may require inspection during export supervision. For cross-border e-commerce sellers (e.g., through Amazon FBA maritime shipping, overseas warehouse stocking), a compliant appraisal report is a necessary prerequisite to ensure the smoothness of first-mile logistics and avoid goods being detained or fined at the port of departure or destination.

Core Differences Between Maritime Shipping Appraisal Report and Air Transport Appraisal Report

Although both are based on safety standards such as UN38.3, the maritime shipping appraisal report differs significantly from the air transport appraisal report in terms of regulatory basis, focus, and specific requirements:

What Core Contents Does a Complete Maritime Shipping Appraisal Report Contain?

A professional maritime shipping appraisal report is far more than just test data; it is a comprehensive conformity assessment document, mainly including:

1. Product and Transport Information Appraisal

Clearly specifies the shipper, consignee, product name, UN number (e.g., UN3480 for lithium-ion batteries), proper shipping name, dangerous goods class (Class 9), packaging grade, etc.

2. Summary of UN38.3 Test Results

Provides a summary of passed UN38.3 test items to prove the safety and reliability of the batteries themselves.

3. Packaging Performance Appraisal and Testing

This is the top priority of maritime shipping appraisal. The report will detail and confirm the following:

• Packaging Type: Whether it meets the requirements for Type II or higher packaging specified in the IMDG Code.

• Packaging Test Results: Whether it has passed tests required by the IMDG Code, such as stacking test, leakproof test, and multiple drop tests.

• Packaging Code: Such as "4G/X...", accompanied by photos.

4. Marking and Labeling Audit

Confirms whether the dangerous goods signs and marks on the goods packaging (e.g., Class 9 Dangerous Goods labels, UN number, shipper/consignee information) are complete and standardized. It also audits accompanying documents such as MSDS.

5. Stowage and Segregation Recommendations

Based on the IMDG Code, provides the stowage category of the goods in the ship's hold or on the deck (e.g., Stowage Category A) and segregation requirements from other dangerous goods.

6. Appraisal Conclusion and Signature/Seal

Clearly presents the final conclusion on "whether the goods meet the conditions for maritime transport of dangerous goods," signed by authorized appraisal personnel and sealed by the institution.

How to Choose a Professional and Reliable Maritime Shipping Appraisal Institution?

Given the complexity and legal liability of maritime shipping appraisal, choosing the right institution is crucial:

1. Primary Qualification: Maritime Administration Recognition

In China, the core qualification is recognition or filing by the competent authority — the Maritime Safety Administration of the People's Republic of China. Appraisal reports issued by such institutions have the highest authority at ports and among shipping companies.

2. Professional Capability and Experience

Choose an institution that has long focused on the appraisal of lithium battery dangerous goods transport. They are well-versed in the complex clauses of the IMDG Code, can accurately handle the determination of various special cases, and provide effective packaging solutions.

3. One-Stop Service Capability

Excellent institutions can provide end-to-end services from UN38.3 testing, packaging scheme design, packaging testing, report compilation to the final issuance of official appraisal certificates, and even assist in on-site loading guidance and maritime declaration.

4. Industry Reputation and Efficiency

Understand the institution's reputation among freight forwarders and shipping companies. Choosing a partner with quick response and whose report format is widely accepted by major shipping companies can greatly improve the efficiency of booking and customs clearance.
