Let me start with what every buyer really wants to know: calcium carbide price. Not a fancy catalog. Not empty promises. Just a fair number per ton, delivered to your port, with no surprises after the invoice arrives.
We are a calcium carbide factory in Inner Mongolia. Our annual output is 36,000 tons. We don’t trade – we melt lime and coke in our own furnaces. That means when you ask about calcium carbide price, we give you a direct quote. No middleman markup.
This page is about our 25-50 mm grade in 100 kg drums. Gas yield: 285 L/KG (tested per batch). Let me walk you through what you get.

The 25-50 mm size is a classic. It feeds well into most acetylene generators and steel desulfurization lances. Not too small to create dust. Not too large to slow down your reaction. Just a solid, reliable granule.
The 100 kg drum is for buyers who have forklifts and want fewer drums to handle. A standard 20' container holds 22.5 tons – that’s 225 drums at 100 kg each. Fewer drums mean less steel, less sealing, and a slightly better calcium carbide price compared to 50 kg drums. We offer both, but here we focus on the 100 kg option.
Let me be honest. The calcium carbide price you see from different suppliers can vary a lot. Why? Because some quote low but add fees for:
Drum colors
Custom markings
Mixed sizes in one container
Short lead times
We don’t play that game. Our calcium carbide price includes:
Your choice of drum color (11 standard RAL shades)
Your own markings (唛头) – painted, not stickered
Mixed loading – different sizes in the same container
Loading within two weeks from deposit
No hidden line items.

You don’t have to fill a whole container with only 25-50 mm. Tell us what else you need. For example:
10 tons of 25-50 mm → Orange drums (100 kg each)
6 tons of 7-15 mm → Blue drums (100 kg each)
4 tons of 4-7 mm → Green drums (50 kg each – yes, we can mix drum weights too)
All in one 20' container. You pay one freight bill. Your calcium carbide price per ton for the mixed order stays exactly the same as a full container of one size. We don’t punish you for flexibility.

Destination port or consignee details
We’ve printed in Thai, Vietnamese, Indonesian, Arabic, Spanish, French, and more. No extra charge.

Our warehouse is less than 5 km from the port in Tianjin. That’s not an accident. We chose that location so we can load fast. From the day you confirm your order and pay the deposit, we typically ship within two weeks.
We export to over 50 countries – Vietnam, Indonesia, Thailand, Philippines, Nigeria, Egypt, Brazil, Argentina, Poland, Turkey, South Africa, and many more. We know each port’s document requirements. No rookie delays.
Not every buyer has the same treasury rules. We offer:
L/C at sight
T/T (30% deposit, balance against copy of bill of lading)
Other arrangements for regular customers
Tell us what works for you. We’ll see if we can match it.

We don’t have REACH (so skip us if your destination absolutely needs it). But we do have:
ISO 9001
SGS inspection reports (pre-shipment or upon arrival)
BV (Bureau Veritas)
Full SDS in English, French, Spanish, Arabic
GHS-compliant drum labels
Origin certificate, commercial invoice, packing list, bill of lading
For most buyers in Asia, Africa, South America, and the Middle East, this is enough.
Calcium carbide hates moisture. Even humid air can slowly ruin it. Store our 100 kg drums:
Off concrete floors (use pallets – concrete wicks water)
Below 40°C, humidity under 50%
Away from water pipes, sprinklers, or leaky roofs
Always reseal after opening
In a dry, cool warehouse, our 25-50 mm stays fresh for 2 years. In humid coastal areas, use within 18 months.

Water + calcium carbide = acetylene gas. Acetylene + spark = explosion. Never open a drum in rainy weather. Never use water on a spill – use dry sand. If a drum gets wet by accident, evacuate the area. Do not move it.
We put clear warnings on every drum. Your team’s training is your responsibility.
I can’t give you a fixed number here because freight rates change. But I can promise you this: when you email us, you will get a transparent calcium carbide price broken down by product, drums, and shipping. No “we’ll check” for three days. No surprise fees at the last minute.
