Safe Shipping of Lithium Batteries: Key Guidelines and Common Mistakes

by

Lithium batteries are pretty much everywhere nowadays. Phones, laptops, EVs, even heavy machinery—they’re all running on them. But the thing is, while they make life easier, they’re not exactly easy to handle when it comes to shipping.

The risk is real. If something goes wrong—bad packaging, wrong handling, even a small mistake—they can overheat or catch fire. In technical terms, this can lead to something called thermal runaway, where the battery just keeps heating up. That’s why they fall under dangerous goods.

Shipping them needs a bit more attention than usual. Not complicated, but definitely not casual either.

Why Lithium Batteries Need Special Handling

The core issue is how these batteries store energy. They pack a lot of power into a small space. That’s great for usage, but it also means they react quickly if something isn’t right.

A damaged battery, too much heat, or even contact between terminals can trigger a problem. Sometimes it’s just overheating; sometimes it gets worse. That’s exactly why they’re treated differently from general cargo.

Because of past incidents, strict rules now apply depending on how you ship:

  • By air: IATA Dangerous Goods Regulations (DGR)
  • By sea: IMDG Code
  • By road: Local DG transport rules

These aren’t just formalities—they’re based on real risks.

Getting the Basics Right

Most issues can actually be avoided if the basics are handled properly. It starts with knowing what you’re shipping.

Lithium batteries are classified under UN numbers, for example:

  • UN3480 – Lithium-ion batteries
  • UN3090 – Lithium metal batteries

Getting this wrong can already cause delays or rejection.

Then comes packaging. This is where a lot of shipments go wrong. Batteries shouldn’t be moving around inside a box. They need to be secured, protected, and packed so nothing shifts during transit. Terminals should also be covered or separated—this part gets overlooked more often than you’d think.

Labels and paperwork might feel routine, but they matter. If the shipment isn’t clearly identified, it creates risk and confusion during handling.

Common Mistakes to Avoid

Even when people know the process, small shortcuts creep in.

One of the biggest mistakes is trying to ship damaged batteries. These shouldn’t go in a normal shipment at all—they require special handling and, in many cases, aren’t allowed on passenger aircraft.

Charge levels are another thing people don’t always take seriously. For air shipments, lithium-ion batteries (UN3480) must usually be at 30% state of charge or lower. This isn’t just a rule—it directly reduces the risk during transit.

Then there’s packaging again. Loose batteries, exposed contact points, weak boxes—it doesn’t take much for things to go wrong if these basics are ignored.

You’ll also see cases where people try to skip proper declaration. It might seem faster at the time, but it usually backfires. Shipments get stopped, questioned, or rejected altogether.

And one common issue? Assuming the same setup works everywhere. It doesn’t. Different routes and carriers follow different rules, so a quick check beforehand saves a lot of trouble.

Final Thoughts

Shipping lithium batteries isn’t something you can treat like regular cargo. There’s a bit more responsibility involved, and small mistakes can turn into bigger problems if you’re not careful.

That said, it’s not difficult either. Once the basics are clear—right classification, proper packaging, and correct charge levels—it becomes part of the routine. Most issues only happen when these simple things are ignored.

In the end, safe lithium battery shipping comes down to getting the small details right—and with Galaxypacs, you have a partner that ensures every shipment moves safely, efficiently, and without compromise.

Why Packaging Optimization Is the Competitive Edge Your Supply Chain Needs

by

Smart packaging isn’t really about shipping boxes on time. It’s about what happens in between—how much material is used, how products move during transit, and how often things arrive exactly as they should. When packaging decisions are made carefully, businesses spend less, ship smarter, and avoid a lot of preventable problems.

Let’s explore the key ways packaging optimization benefits businesses and why it’s worth paying attention to.

Reducing Packaging Costs
One of the first areas where businesses see change is packaging cost. Boxes and packing materials often account for a surprisingly large share of operational expenses. Many companies use oversized cartons simply because they feel safer. In reality, larger boxes usually mean more cardboard, more filler, and higher shipping charges due to dimensional weight.

Let’s take a simple example. A product that comfortably fits in a 12×9×6 inch box is shipped in a 16×12×8 inch one instead. By switching to the smaller size, cardboard use drops noticeably, filler material is reduced, and shipping costs come down because the package takes up less space. When this adjustment is applied across thousands of shipments each year, the savings can easily run into tens of thousands of rupees—without changing the product itself.

Reducing Product Damage
When products arrive damaged, the impact goes beyond the item itself. There’s the cost of replacement, the time spent resolving issues, and the frustration on the customer’s end. In many cases, the problem isn’t how the shipment was handled, but how it was packed. Packaging that allows items to move or knock against each other during transit is far more likely to fail.

For an illustration, consider glass bottles. When they’re shipped in oversized cartons with loose bubble wrap, cracking is almost inevitable. A tighter fit, proper inserts, or stronger cushioning materials make a noticeable difference. Simply removing excess empty space inside the box can significantly reduce damage. Fewer broken products mean fewer returns and far less time spent dealing with issues that could have been avoided.

Reducing Freight Costs
Freight costs are also closely tied to how products are packed. Shipping charges are often based on volume as much as weight, which means space matters. Light products can still be expensive to ship if they’re packed inefficiently. This becomes especially clear when pallet loads are involved.

Imagine a pallet carrying 100 items, with each box holding just five units. If the box design is improved to hold ten units instead, the number of boxes per pallet doubles. Fewer pallets are needed, trucks are used more efficiently, and freight costs drop. As a side benefit, fuel consumption and environmental impact are reduced as well.

Improving Shipping Efficiency
Packaging also shapes how smoothly a warehouse runs day to day. It’s not only about box sizes or materials—it affects how quickly orders can be packed and how easy they are to handle once they’re ready to ship. When packing takes longer than it should, those lost seconds quietly add up.

For instance, sometimes packing processes can become more complicated than necessary. Extra tape, layers of bubble wrap, and additional boxes slow teams down. When packaging is simplified, the change is immediate. Orders move faster, material usage drops, and packages are easier to lift, stack, and move. Even saving 30 seconds per order can free up several hours of labor over a week, helping teams handle higher volumes without adding costs.

By focusing on the core principles of packaging optimization—right-sizing boxes, making better use of pallets, and simplifying packing steps—Galaxypacs helps businesses make packaging a smarter, leaner, and more dependable part of their operations, cutting costs, reducing waste, and improving the customer experience.

UN-Approved Packaging Explained: Meaning, Markings, Tests, and Compliance

by

Have you ever wondered what makes certain packaging safe enough to transport hazardous materials worldwide? When it comes to shipping dangerous goods, packaging must withstand extreme handling while preventing leaks, spills, or contamination. From chemicals and batteries to flammable liquids and toxic substances, even a small packaging failure can result in serious safety, environmental, and financial consequences. This is where UN-approved packaging plays a critical role.

What Exactly Is UN-Approved Packaging?

UN-approved packaging is packaging designed specifically for transporting dangerous goods safely. Before it’s certified, the packaging goes through strict tests to make sure it can withstand real shipping conditions, from handling and stacking to long-distance transit. These standards come from the United Nations Recommendations on the Transport of Dangerous Goods and are recognised and used worldwide across air, sea, road, and rail transport.

In simple terms, this approval brings peace of mind. Hazardous materials stay securely contained during transport, lowering risk and helping protect people, property, and the environment, even under challenging conditions.

How Do You Identify UN-Approved Packaging?

Now that we’ve covered what UN-approved packaging is and why it’s important, the next step is knowing how to identify it.
UN-approved packaging can be identified by the UN symbol printed or embossed on the package, followed by a specific code. This code provides detailed information about the packaging, including:

Type of packaging (identified by a number)

1 – Drum

2 – Barrel

3 – Jerrican

4 – Box

5 – Bag

6 – Composite packaging

7 – Pressure receptacle

Material of construction (identified by a letter)

A – Steel

B – Aluminium

C – Natural wood

D – Plywood

F – Reconstituted wood

G – Fibreboard

H – Plastic

L – Textile

M – Multi-wall paper

N – Metal (other than steel or aluminium)

Packing group (indicating the level of danger)

X – Packing Group I (high danger)

Y – Packing Group II (medium danger)

Z – Packing Group III (low danger)

Maximum gross mass (for solids) or specific gravity (for liquids)

Year of manufacture

Maximum gross mass (for solids) or specific gravity (for liquids)

Country code or manufacturer’s mark

Example:
UN 4GV/X35/S/24/SGP/GALX1596

Let’s take an example from one of the boxes shown in the above picture. At first glance, this code can look confusing, but each part has a specific meaning. The UN mark shows that the packaging has been tested and approved under the UN Recommendations on the Transport of Dangerous Goods. The next part, 4G, tells you the packaging type—in this case, a fibreboard box. And V denotes that non-specific (variable) inners are permitted.

The letter X indicates that the packaging is approved for Packing Groups I, II, and III. In simple terms, this means it can be used for high-, medium-, and low-danger goods, as long as it stays within the tested limits. The number 35 refers to the maximum gross mass allowed, measured in kilograms. The letter S confirms that the packaging is intended for solids or for usage with inner packaging. 24 represents the year of manufacture, which is 2024. SGP identifies Singapore as the country where the packaging was approved by the competent authority. Finally, GALX1596 is the manufacturer’s identification mark, used to trace the company or facility responsible for producing the UN-marked packaging.

Why UN Certification Matters?

When it comes to transporting hazardous materials, cutting corners on packaging isn’t an option. Using the wrong or non-certified packaging can put shipments, workers, and businesses at serious risk. The consequences go beyond minor delays—they can escalate into operational problems, legal trouble, and safety hazards.

Here are some of the risks of using non-UN-certified packaging:

Shipment Rejection
If packaging doesn’t meet the required standards or lacks certification, carriers may refuse to move the shipment. This can cause unexpected delays, missed deadlines, and extra costs for the business.

Regulatory Penalties
Dangerous goods regulations are strict. Failing to comply can lead to fines, enforcement actions, or even legal cases. Over time, non-compliance can also create ongoing burdens, taking up time and resources that could be better spent elsewhere.

Safety Risks
Poorly designed or incorrect packaging increases the chance of leaks, fires, chemical reactions, or other accidents during transport. These incidents put employees, transport crews, property, and the environment at risk.

Reputational Impact
Not meeting UN standards doesn’t just affect one shipment. It can damage customer trust, strain partnerships, and attract scrutiny from regulators.

For organisations handling dangerous goods, UN certification is more than a box to tick. It’s a key part of managing risk, keeping people safe, and ensuring the supply chain runs smoothly.

Testing of UN Packaging

UN certification isn’t easy to get. Packaging must prove it can survive real transport conditions. This means passing a series of practical tests that show whether it can withstand common stresses—because in logistics, things rarely go perfectly. These tests include:

Drop Test
Accidental drops happen when packages are handled, loaded, or unloaded. This test checks if the packaging can survive knocks and bumps without cracking, breaking, or leaking. It ensures that the contents stay protected even when mistakes occur.

Leakproofness Test
For liquids, keeping them contained is critical. This test confirms that the packaging can hold liquids securely during transit. It prevents leaks that could harm people, other cargo, or the environment. Essentially, it ensures liquids stay safely inside their packages from warehouse to delivery.

Vibration Test
Packages are constantly moving during transport—whether it’s bumps on the road, engine vibrations, turbulence in the air, or motion on a ship. This test simulates those movements to see if the packaging can keep its contents stable. It checks whether items stay secure and intact, even when shaken, jostled, or constantly moved during the journey.

Stacking Test
In warehouses and transport units, packages are often stacked. This test checks if packaging can hold up under weight without collapsing, bending, or losing its shape. It ensures items stay safe even when stored or transported in stacks.

Hydrostatic Pressure Test
When liquid packages are transported, changes in altitude, temperature, or movement can increase pressure inside the container. This test checks whether the packaging can handle that internal pressure without deforming, splitting, or failing. It helps confirm that the container stays strong and intact even when pressure builds up during the journey.

Only packaging that passes all these tests can be certified. This confirms it is suitable for safely transporting dangerous goods.

This depth of testing is also why where your packaging comes from matters. At Galaxypacs, UN-certified packaging is developed to match specific dangerous goods requirements and is certified by ERRL Singapore, in line with ICAO and IMDG regulations. Built for multimodal transport, these solutions support compliance, smoother customs movement, and the safe flow of goods across global supply chains.
