You want to buy calcium carbide in bulk. But you don’t want to fight with suppliers who only offer one size or charge extra for basic things like drum colors or your own markings.
We make it simple. Our factory in Inner Mongolia produces calcium carbide in every granulation: 1‑4 mm, 4‑7 mm, 7‑15 mm, 15‑25 mm, 25‑50 mm, 50‑80 mm, and 80‑120 mm. And we pack everything in 100 kg steel drums – UN approved, stackable, and built for ocean freight.
When you buy calcium carbide from us, you get a real partner. Not a trader who disappears after the first shipment.

A 20' container holds 22.5 tons of calcium carbide in 100 kg drums. That’s 225 drums per container. Fewer drums than 50 kg means less steel, lower packaging cost, and faster loading. If your warehouse has a forklift, 100 kg drums are the most efficient way to buy calcium carbide in large volumes.
But we also understand that some lines need smaller drums. That’s fine too – we offer 50 kg as an option. You choose.
You don’t need a separate container for each size. Tell us what you need:
6 tons of 1‑4 mm (fine, fast reaction)
8 tons of 25‑50 mm (all‑purpose)
4 tons of 50‑80 mm (heavy acetylene)
4 tons of 80‑120 mm (slow release)
We pack each size into 100 kg drums with different colors. Your warehouse team grabs the right drum without reading tiny labels. One container, one freight bill, one set of documents. That’s how smart buyers buy calcium carbide – mixed, flexible, and cost‑effective.

Standard drums are boring. We offer 11 RAL colors. For example:
Yellow → 1‑4 mm (fine)
Light green → 4‑7 mm
Blue → 7‑15 mm
White → 15‑25 mm
Red → 25‑50 mm
Black → 50‑80 mm
Dark grey → 80‑120 mm
Or pick your own shade. No extra fee.
Stickers fall off in heat or humidity. We paint directly on the drum. Send a PDF or AI file. We’ll print:

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 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 (dry sand only). If a drum gets wet, evacuate – do not move it.
We put warnings on every drum. Train your people.
