Hi Purchasing Manager,

If you are sourcing Calcium Carbide through intermediaries, here is what switching directly to a primary manufacturer like Zhongying Chemical looks like:

Feature	Middleman / Traders	Zhongying Chemical (Direct Factory)
Gas Yield	Inconsistent across batches	Guaranteed ≥ $\ge 295 \text{ L/kg}$ consistently
Price	Includes trader margin	Direct factory pricing (FOB/CIF)
Sizing Control	Mixed kiln sources	Custom screened ( $25-50\text{mm} / 50-80\text{mm}$ )
Packaging	Standard packaging	Nitrogen-purged UN steel drums

With 15 years of chemical manufacturing experience, we ensure your acetylene generators run at peak efficiency with zero unexpected downtime.

Could I provide a competitive quote for your next sea freight shipment to your destination Port ?

Thanks and regards,
