Let me give you the short version first. We are a calcium carbide factory in Inner Mongolia. Our furnaces run 24/7, and last year we produced 70,000 tons. That’s not a trader’s number. That’s our actual output.
We ship from Tianjin – our warehouse is less than 5 km from the port. That means fast loading, usually within two weeks after you confirm the order.
Now, let’s talk about what you actually care about: calcium carbide stone price, drum options, and whether we can pack the way you want.

All standard sizes: 1‑4 mm, 4‑7 mm, 7‑15 mm, 15‑25 mm, 25‑50 mm, 50‑80 mm, and 80‑120 mm. Gas yield: 300 L/KG across all grades. We test every batch. You get a certificate with each shipment.
Where do our customers use it?
Acetylene gas for welding and cutting
Steel desulfurization – cleaner metal, faster processing
Calcium cyanamide – fertilizer and chemical raw material
PVC and other chemical synthesis
We export to over 50 countries – from Vietnam and Indonesia to Nigeria, Brazil, Poland, Turkey, and South Africa. We know the paperwork for each port.

You have two options. Both are UN‑approved steel drums.
| Drum Weight | Drums per 20' Container | Total Net Weight |
|---|---|---|
| 50 kg | 450 drums | 22.5 tons |
| 100 kg | 225 drums | 22.5 tons |
Why two sizes? Because not every plant has a forklift. If your workers move drums by hand, 50 kg is safer. If you have loading docks and forklifts, 100 kg means fewer drums to handle.
The calcium carbide stone price is slightly different between the two. 50 kg drums use more steel – twice the drums, twice the steel. So the calcium carbide stone price per ton for 50 kg is a bit higher. But many customers tell us the handling savings are worth it. We quote both. You decide.

You don’t need a full container of just one size. Tell us: “I want 10 tons of 25‑50 mm, 6 tons of 7‑15 mm, and 4 tons of 50‑80 mm.” We pack each size into different colored drums, load them into the same 20' container, and send you one packing list.
Why colors? Because your forklift driver doesn’t want to read small labels from 10 meters away. He sees blue – he knows it’s 7‑15 mm. Red means 25‑50 mm. No mistakes.
We have 11 standard RAL colors. Or send us a color code. No extra charge.

Stickers fall off in heat or humidity. We paint directly on the drum. Send a PDF or AI file. We’ll print your logo, product name, size, net weight, batch number, hazard warnings (UN1402 / Class 4.3), and destination port. We’ve printed in Thai, Arabic, Spanish, French, Vietnamese, Indonesian – you name it.
All included in your calcium carbide stone price. No hidden add‑ons.

Three main things:
Drum size – 50 kg drums cost more per ton than 100 kg drums.
Quantity – Full container orders get a better rate than LCL.
Destination port – Freight varies.
We don’t play games. When you ask for a calcium carbide stone price, we send you a clear breakdown: product cost per ton, drum cost, and estimated freight to your port. No “we’ll check” for three days. No surprise fees.
Want to lower your calcium carbide stone price? Mix sizes in one container. Order full containers. Choose 100 kg drums if your handling allows. We’ll help you find the most cost‑effective setup.
ISO 9001
SGS inspection reports (pre‑shipment or upon arrival)

We do not have REACH. If your destination requires it, please check locally.

Keep drums off concrete floors (use pallets). Store below 40°C, humidity under 50%. Away from water pipes. Reseal after each use. In a dry warehouse, our calcium carbide lasts 2 years. In humid coastal areas, use within 18 months.
Water + calcium carbide = acetylene gas. Acetylene + spark = explosion. Never open a drum in wet weather. Never use water on a spill – use dry sand. If a drum gets wet, evacuate. Do not move it.
We put warnings on every drum. Train your people.
