Compliance Safeguards Lithium‑Battery Exports | Yongnuo Packaging Provides a Detailed Overview of Core Regulations and Practical Guidelines for Lithium‑Battery Hazardous‑Goods Packaging

As demand for energy storage, new‑energy electric vehicles, and consumer lithium‑ion batteries continues to grow, lithium batteries—classified as Class 9 miscellaneous hazardous goods—are subject to increasingly stringent regulations across all modes of transport, including maritime, air, and land. Non‑compliant packaging can easily result in customs detentions, carrier rejections, and serious safety risks such as transportation‑related fires. With 25 years of expertise in the manufacture of hazardous‑goods packaging, Xuchang Yongnuo Packaging Co., Ltd., backed by comprehensive certifications for producing hazardous‑material packaging and standardized UN‑compliant wooden and cardboard crate production lines, helps lithium‑battery manufacturers in Central China identify common pain points, regulatory requirements, and compliance solutions for lithium‑battery hazardous‑goods packaging.

I. Why must lithium batteries be packaged in dedicated hazardous‑goods containers?
The electrolyte inside lithium‑ion battery cells is highly flammable; during transport, compression, impact, or electrode short circuits can easily trigger thermal runaway, leading to fire and explosion. Standard cardboard boxes and rudimentary wooden crates offer no protective measures and fail to comply with international transportation regulations.
Regulatory requirements
In accordance with the United Nations TDG Regulations, the IMDG Code for maritime transport, and the IATA DGR for air transport, lithium‑ion batteries (UN 3480), lithium batteries integrated into equipment (UN 3481), and lithium‑metal batteries (UN 3090) with cell rated energies exceeding 20 Wh or battery pack rated energies exceeding 100 Wh must be packaged in UN packaging compliant with Class II hazardous materials requirements. Shipments lacking valid UN packaging certification are prohibited from customs clearance and export.
Domestic commodity inspection regulations clearly stipulate that hazardous‑package containers for export must pass performance testing and obtain a “Hazardous‑Package Performance Inspection Certificate”; untested packaging may not be used to ship lithium batteries for export.
Essential security protection
Standard packaging lacks insulating cushioning and short-circuit protection, whereas Yongnuo lithium‑battery hazardous‑goods containers are equipped with built‑in anti‑static foam, insulating partitions, and secure retaining trays to prevent cell movement and electrode contact. The container has passed a comprehensive suite of tests—including 1.2‑meter drop, 3‑meter stacking, and vibration‑and‑compression resistance—ensuring it can withstand the shocks and vibrations of long‑distance sea and land transport.
Strict regulatory thresholds for customs clearance and transportation
Shipping and airline carriers verify UN markings, hazardous‑package certificates, and Class 9 hazard labels prior to acceptance. If the packaging material, printed markings, or load‑bearing capacity fail to meet the required standards, the shipment will be returned outright, resulting in substantial port‑stay fees and costly re‑routing expenses.
II. Four Common Violations in Lithium Battery Hazardous Packaging (Frequent Pitfalls for Enterprises)
1. Mixing ordinary packaging to substitute for UN‑certified hazardous‑goods packaging, without proper hazardous‑goods packaging qualifications.
To cut costs, many small and medium-sized lithium‑ion battery manufacturers use standard five‑layer cardboard boxes and non‑heat‑treated wooden crates to ship high‑power energy storage batteries.
Risks: Customs inspection may determine that the packaging lacks a hazardous‑package performance report, resulting in detention of the entire container; after being stacked in a shipping container, the container’s body may be damaged, leading to cell short‑circuiting and spontaneous combustion.
Yongnuo Solutions: Our full range of UN‑compliant cardboard boxes and solid‑wood hazardous‑goods crates are manufactured under license, with complete packaging‑test documentation included upon shipment, and support air, sea, and rail transport.
2. UN identification and hazardous materials labels are improperly printed or missing.
Common errors: the packaging lacks a UN number, the Class 9 lithium‑battery marking is unclear, the rated energy in watt‑hours (Wh) is not indicated, the “This Side Up” or “Fragile” labels are missing, and the labels have peeled off when exposed to water.
2026 Latest Regulatory Update: Lithium battery labels are now uniformly updated to a dedicated battery marking; UN3480/3481 codes must be printed in a waterproof, abrasion‑resistant format, and the package gross weight, manufacturer’s code, and packing group YII must also be indicated.
Yongnuo Craft: The hazardous‑package container body is pre‑printed with abrasion‑resistant water-based ink, and can be custom‑printed with compliant Chinese and English markings. A complete set of UN codes, hazard labels, and handling warnings is printed in a single pass, eliminating the need for post‑production manual labeling that may peel off.
3. No internal insulating partitions; no short-circuit protection has been implemented.
Bare cell packaging, lack of insulation protection on the battery’s positive and negative terminals, and absence of cushioning or padding inside the container are the most common causes of fires. Regulation P903, under the Packaging Provisions, explicitly stipulates that cells in a single container must be individually isolated and securely fastened, and their terminals must not come into contact with the container or any other metallic components.
Yongnuo custom packaging: Tailored to cell dimensions, it includes EPE insulating spacers, plastic insulating caps, and flame-retardant foam padding, ensuring zero movement inside the carton and compliance with PI965/966 air‑freight packaging standards.
4. The dimensions, load capacity, and battery capacity of the hazardous package are mismatched.
High‑power energy‑storage batteries and power batteries weighing over 12 kg, when packed in lightweight, thin‑wall corrugated UN‑compliant crates, suffer box deformation and damage after stacking; meanwhile, small‑capacity cells housed in oversized containers exhibit excessive internal voids, leading to impact‑induced damage.
Yongnuo Flexible Customization: We can design battery‑box structures to accommodate lithium‑ion battery sizes ranging from 10 Ah to 5,000 Ah, with tailored net weights per unit. For heavy‑duty power batteries, we offer integrated packaging featuring thickened solid‑wood UN‑standard crates paired with pallets, capable of supporting heavy‑weight energy‑storage systems up to 100 tonnes.
III. Classification and Compatibility Guide for Lithium Battery Hazardous Packaging (Xuchang Yongnuo Standardized Products)
1. UN‑certified corrugated cardboard boxes (suitable for consumer lithium batteries and small battery packs)
Applications: mobile phone batteries, small energy-storage cells, power-tool batteries, and devices with built-in batteries.
Standard: Five‑ply or seven‑ply high‑strength kraft paper, with an antistatic inner layer and built-in partitioned insulating cushioning; it has passed a full suite of drop‑and‑stack performance tests and complies with UN3480 and UN3481 transportation requirements.
2. Heat-treated UN solid wood hazardous‑goods crates (the preferred choice for power batteries and large‑scale energy storage systems)
Applications: electric vehicle lithium batteries, energy storage battery clusters, and industrial high-capacity battery packs.
Advantages: The wooden crates undergo IPPC heat treatment for export quarantine, come with in-house hazardous‑package performance‑testing qualifications, offer high rigidity and excellent crush resistance, can be stacked on pallets for easy forklift handling, and provide moisture‑proof and impact‑resistant protection during long‑distance sea transport.
3. Integrated Pallet Hazardous Packaging Kit
For full-container‑load shipments of lithium batteries, we provide a complete solution comprising wooden crates or UN‑certified containers paired with fumigated pallets. The crate bodies are pre‑equipped with tie‑down points to ensure stable, non‑displacing stowage after containerization, fully complying with maritime container securing regulations.
IV. Key Reminders on the 2026 New Regulations for Lithium‑Ion Battery Hazardous Packaging (Essential Reading for Foreign Trade Enterprises)
Lithium Battery SOC Management: For air transport, lithium batteries with a capacity exceeding 100 Wh must have a state of charge (SOC) not exceeding 30%; the packaging documentation must clearly indicate the SOC value, and the hazardous‑materials shipping plan must comply with low‑SOC transportation safety requirements.
Packing‑stacking test upgrade: All UN‑certified air‑freight cartons must now pass a 24‑hour stacking‑pressure test at 3 meters; lightweight standard UN‑compliant cartons are no longer permitted for air transport of lithium batteries.
Dangerous Goods Packaging Certificate Management: Packaging performance test reports must be strictly matched to the UN number and the gross weight of the container. Different-sized dangerous goods packages require separate test certificates; mixed use is invalid.
Sodium-ion batteries have been assigned new UN numbers—UN3551 and UN3552—and Yongnuo has simultaneously completed the development of corresponding hazardous‑goods packaging, addressing both lithium‑ and sodium‑ion battery packaging requirements.
