1-4 mm Calcium Carbide – 245 L/KG, Custom Colors, Mixed Loads & Your Own Marks
Before we talk numbers, let’s remember what calcium carbide actually is. It’s a dark grey, rock-like material made from lime and coke in an electric arc furnace. Crush it into fine granules – like our 1-4 mm – and it reacts almost instantly when wet. That fast reaction makes it perfect for certain chemical processes, but also means you need a supplier who understands how to handle, pack, and ship small particles without losing quality or creating dust chaos.
We are that supplier. Based in Inner Mongolia. Shipping from Tianjin port (our warehouse is barely 5 km from the docks). And we’ve spent years learning how to offer real customization – not just lip service.

Why 1-4 mm? And Why 245 L/KG?
Most people assume bigger lumps give higher gas yield. Not always. Our 1-4 mm calcium carbide delivers a reliable 245 L/KG – tested batch by batch. That’s not a typo. 245 L/KG is what you get from this specific fine grade. It’s consistent, repeatable, and perfect for:
-
Continuous acetylene generators with small feed nozzles
-
Chemical synthesis where you need fast, complete reaction
-
Blending into other compounds where powder dispersion matters
Now, let’s talk about what really matters to your bottom line: the calcium carbide powder price. Because fine granules usually cost more to produce – more crushing, more screening, more dust control. But here’s the good news: we keep our calcium carbide powder price reasonable because we do everything in-house. No middlemen. No surprise fees.
And when you mix different sizes in one container, your effective calcium carbide powder price drops even further – because you split shipping and clearance costs across multiple products.

Your Markings – Exactly What You Need
Empty drums are like blank canvases. We print yours with any information you want. Common requests include:
-
Your company name and logo
-
“Calcium Carbide – 1-4 mm – 245 L/KG”
-
Net weight: 50 kg or 100 kg (we offer both drum sizes)
-
Batch number and production date
-
“DANGER: Reacts with water. Flammable gas acetylene.”
-
UN1402 / Class 4.3 diamond
-
Destination port and consignee details
We’ve printed markings in Thai, Vietnamese, Indonesian, Arabic, Spanish, French, and Polish. Send a PDF or AI file. We’ll proof it with you, then paint it on the drums before filling.
Mixed Drum Weights in the Same Container – Yes, We Do That
Some orders call for 50 kg drums for a remote site with no forklift, and 100 kg drums for the main plant. Same container. We brace them separately, label each pallet clearly, and provide a detailed packing list.
Example: 10 tons of 1-4 mm in 100 kg drums (100 drums) + 5 tons of 50-80 mm in 50 kg drums (100 drums). Total 15 tons. One shipment. Two drum weights. Your calcium carbide powder price for the 1-4 mm part stays exactly the same as if you ordered a full container – no penalty for mixing.

Real Customer Example – Yellow Drums, Custom Markings, Mixed Sizes to Thailand
A chemical company in Rayong, Thailand, needed 1-4 mm (yellow drums) for a specialty synthesis line, plus 25-50 mm (red drums) for their acetylene plant. They wanted their logo in Thai, plus “Keep Dry” in both Thai and English. And they wanted 50 kg drums for the 1-4 mm (easier to tip into their small reactor) and 100 kg drums for the 25-50 mm.
We built the order in one container. Delivered in 18 days from deposit. They later asked for a repeat order and also asked about our calcium carbide powder price for an even finer 0-1 mm grade (which we can also produce on request).
That’s what happens when a calcium carbide supplier actually listens.
Safety – Fine Granules React Faster, So Be Extra Careful
1-4 mm calcium carbide has more surface area than large lumps. That means when it touches water or even humid air, the reaction is faster and more intense. Acetylene builds up pressure quickly.
Rules you must follow:
-
Never open a 1-4 mm drum in rainy weather or high humidity.
-
Always reseal the drum immediately after taking material.
-
Store drums off concrete floors – use pallets or racks.
-
Keep away from any water source – pipes, sprinklers, flooded areas.
-
In case of fire or spill: DO NOT use water. Use dry sand, dry powder extinguishers, or inert gas.
We put clear warning labels on every drum, but your team’s training is your responsibility.

Storage Conditions – 1-4 mm Specifics
Because fine particles are more sensitive to moisture, we recommend:
-
Use within 12 months in humid coastal regions
-
Up to 2 years in dry, inland warehouses (below 40°C, humidity under 40%)
-
Always keep drums sealed
-
Store in a cool, well-ventilated area away from direct sunlight
Under good conditions, our 1-4 mm calcium carbide maintains 240-245 L/KG even after 18 months. We’ve seen it ourselves.
