If your business ships products containing batteries internationally, there are some important shipping and packaging considerations you will need to comply with to ensure they arrive there safely and without damage or delay. Read on for a simple guide.
Batteries are classified by their chemical composition, which directly dictates their risk level and transport requirements under international cross-border logistics Brazil frameworks. When preparing shipments from Brazil, you will primarily deal with four distinct categories:
Wet batteries, also known as flooded lead-acid batteries, are commonly found in vehicles and backup power systems. They contain a liquid electrolyte solution, typically sulfuric acid, which enables the chemical reactions necessary to generate electricity. These batteries are known for their affordability and ability to provide high currents.
Nickel-metal hydride (NiMH) batteries are rechargeable batteries often used in portable electronics and tools. They offer a higher energy density than alkaline batteries, meaning they can store more energy in the same space. NiMH batteries are known for their long cycle life and relatively low self-discharge rate, but they can be more expensive than other types.
Dry or alkaline batteries are the most common type of consumer batteries used in everyday devices like remote controls, toys, and flashlights. They use a paste-like electrolyte, usually potassium hydroxide, which makes them more portable and less prone to leakage than wet batteries. Alkaline batteries are available in various sizes and offer a good balance of performance and cost.
Wet batteries, also known as flooded lead-acid batteries, are commonly found in vehicles and backup power systems. They contain a liquid electrolyte solution, typically sulfuric acid, which enables the chemical reactions necessary to generate electricity. These batteries are known for their affordability and ability to provide high currents.
You can ship batteries safely by strictly complying with international packaging, labeling, and state-of-charge regulations required by global transit networks. Certain categories, specifically lithium-ion and lithium-metal cells, carry inherent risks of overheating, thermal runaway, and combustion if handled incorrectly.
This is why aviation authorities and global customs agencies enforce rigid protocols for lithium battery transportation.
These international standards require certified packaging materials, explicit exterior labeling, and specialized cargo documentation to ensure safe handling inside aircraft cargo holds.
An improperly packed lithium battery can ignite under pressure or temperature shifts, creating fires that are exceptionally difficult to suppress at high altitudes.
While dry cell alkaline and nickel-metal hydride batteries are considerably safer, they still require isolated packaging to prevent short circuits caused by terminal contact during transit. Under no circumstances can damaged, swollen, or defective batteries be shipped, as they represent an immediate safety hazard.
To comply with lithium battery regulations, you must verify whether your cells are shipped inside a device, packed alongside it, or sent as standalone cargo. The International Air Transport Association (IATA) classifies lithium-ion and lithium-polymer batteries as Dangerous Goods.
[Battery Configuration] ➔ [Check IATA Guidelines] ➔ [Apply Proper UN Labels & MSDS]
As the exporter, you are legally accountable for ensuring your packages align with the latest IATA Dangerous Goods Regulations. Your shipments must display the correct hazard handling labels and include a Material Safety Data Sheet (MSDS) or a formal lithium battery shipping declaration.
Batteries contained in equipment (UN3481): The power source is securely installed inside the device (like an enclosed smartphone). The outer casing must protect the power switch from accidental activation.
Batteries packed with equipment (UN3481): The battery is detached but enclosed in the same retail box as the device (such as a laptop with a removable power pack). The battery must be placed in an isolated inner liner.
Batteries shipped alone (UN3480): Standalone power banks or bulk cells. These face the most restrictive volume limits and cannot be transported on passenger aircraft.
If the lithium battery is installed in the equipment it powers:
If the lithium battery is packed with the equipment but not installed:
If you're shipping lithium batteries alone:
You package dry cell and nickel-metal hydride batteries by isolating the positive and negative terminals to eliminate any chance of accidental short circuits.
This category includes alkaline-manganese, zinc-carbon, and nickel-cadmium batteries. Because they are sealed and non-vented, they do not present a risk of fluid leakage during standard transport conditions.
While these variants are exempt from full Dangerous Goods declarations, Brazilian exporters should follow clear warehouse packaging playbooks to ensure smooth handling:
The safest way to ship batteries is within the device they power. Ensure terminals are protected (e.g., with tape or caps) and pack the device to prevent accidental activation.
If shipping multiple loose batteries, protect each battery's terminals with individual packaging (e.g., plastic bags or caps), and separate batteries within the box using non-conductive (e.g. cardboard) dividers.
Fill all empty spaces within the box with cushioning material like bubble wrap or packing peanuts to prevent batteries from moving and potentially short-circuiting.
Choose a strong, double-walled box or container to hold all the contents securely. Seal the outer box with plenty of strong tape, and attach the correct shipping label clearly to the outside. For dry and nickel-metal hydride batteries, this will typically be a standard shipping label.
If you're shipping alkaline batteries specifically, remove them from the devicee keep them in their original packaging if possible, and wrap each battery individually before placing them in a double-walled box.
International regulations require wet batteries to be securely packed in UN-certified specification packaging, held completely upright, and equipped with functional ventilation to prevent dangerous gas accumulation.
Wet cells utilize a liquid electrolyte fluid and naturally vent gases under temperature shifts, meaning any tilt can lead to corrosive leaks.
Failing to properly declare wet cell shipments can lead to immediate operational stops at international export hubs. Your logistics team must follow a strict preparation sequence:
Use a strong, rigid outer box or container made of corrugated cardboard or other durable material. It must meet UN specifications for shipping hazardous materials and have an acid/alkali leak-proof liner.
If you're shipping multiple wet batteries, enclose each in its own leak-proof container (e.g., a sealed plastic bag or container) with absorbent material, such as vermiculite or acid-absorbing pads.
Separate them within the box using non-conductive dividers (e.g., sturdy cardboard or foam) to prevent them from touching and potentially short-circuiting.
Fasten the batteries securely in place within the box using packing materials like bubble wrap or foam. Ensure any vent caps are facing upwards to allow for the release of gases and prevent pressure build up.
Fill all remaining empty spaces within the box with cushioning material like bubble wrap or packing peanuts to prevent batteries from moving and potentially causing damage.
Seal the outer box with heavy-duty packing tape, ensuring all seams and edges are completely covered.
Receita Federal and ANVISA regulations impact battery exports by enforcing strict customs declarations, product certifications, and safety inspections on all hazardous cargo leaving Brazilian territory. According to data from SEBRAE, clearing regulatory hurdles is a primary friction point for growing Brazilian e-commerce operations trying to scale internationally.
When exporting devices with power sources, you must ensure your documentation matches the requirements of both Brazilian customs and the destination country:
Shipping damaged or faulty batteries can be extremely dangerous, with the risk of fire, smoke and fumes. For this reason, any battery that is suspected or known to be defective (swelling, corroding or leaking, for example) is not permitted for shipping within the DHL Express network.
When you're shipping lithium-ion batteries by air, it's essential to follow specific regulations regarding their state of charge (SoC). The SoC, which reflects the battery's charge level compared to its full capacity, must not exceed 30% during transit. It's your responsibility to ensure compliance with this rule, as exceeding the limit can lead to safety risks.
When shipping lithium batteries, the responsibility for safe and compliant shipping rests with you as the shipper. You are legally obligated to follow all relevant regulations, such as UN3480 and UN3481. Failing to meet with international or local regualtions can lead to serious consequences, including legal liabilities in the event of accidents or incidents involving your shipment. To avoid this, it's crucial to familiarize yourself with and strictly adhere to the UN and IATA guidelines for shipping lithium batteries.
If you're shipping batteries internationally, it's important to be familiar with the regulations that apply. Some types, like lithium batteries, are considered Dangerous Goods, meaning they need special care when packing and labelling to ensure safe transportation. Failing to declare or properly pack these batteries can lead to serious safety risks. Other batteries may be classified as restricted, which means there are specific rules about what types and how many you can send in a single shipment.
It might sound obvious, but when shipping batteries within devices, make sure they are completely powered down and take steps to prevent accidental activation. This may involve taping over power switches or removing batteries and packing them separately. This is crucial to prevent short circuits and potential fires during transit.
Make sure your package is clearly labeled with the right warnings, especially when shipping lithium batteries. These shipments require specific hazard labels and markings to keep everyone safe. Don’t forget to complete the necessary paperwork, like Material Safety Data Sheets (MSDS) and Shipper’s Declarations, as outlined by lithium battery shipping regulations. Proper labeling and documentation not only help you stay compliant, but also ensure that everyone handling your package knows what’s inside and can take the right precautions along the way.
You can prevent accidental short circuits by completely powering down all shipped electronic devices and taping over any exposed electrical switches or connection points. Taking these precautions prevents devices from accidentally turning on due to vibration or movement inside the package.
In addition to securing the power switches, make sure your outer packaging features the required hazard labels and handling markers.
