Package and route
Packing notes
Supplier page references new iron drums in 50 kg and 100 kg options.
Confirm net weight, gross weight, drum dimensions, palletization, container loading plan, and whether palletized or non-palletized shipment is required.
Request photos or inspection records for drum sealing, markings, batch labels, and container loading condition.
Confirm DG-compliant packaging suitability for UN 1402 and export transport mode before order placement.
Applications and sourcing options
Check whether this product fits the buyer's actual application.
Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.
Use context
Common applications
Acetylene gas production feedstock for qualified industrial facilities
Industrial gas supply chain procurement where gas yield and lump size are key purchasing criteria
Chemical distribution into regulated industrial channels
Steel industry raw material sourcing where calcium carbide specifications match buyer requirements
How we compare
Sourcing options
Request quotation by particle size: 25-50 mm, 50-80 mm, or 80-120 mm.
Request gas yield tier pricing for 285, 295, or 305 L/kg if available.
Request 50 kg or 100 kg iron drum packing with DG documentation included.
Request FOB China port and CIF/CFR India quotations with confirmed DG vessel space.
Request pre-shipment inspection and batch-specific COA before balance payment.
Calcium carbide is a dangerous goods cargo; request SDS, COA, DG declaration, packing certificate, transport classification, and export documentation before RFQ approval.
Verify UN 1402 classification, packing group, hazard labels, HS code, and destination-country import controls with the freight forwarder and importer.
Do not rely on marketplace claims as regulatory approval; importer should confirm India customs, port, and end-use compliance requirements independently.
Ask supplier to provide batch-level gas yield report, CaC2 assay or effective content basis, particle size report, and impurity profile where available.
Pay attention to moisture exposure, drum seal integrity, and impurity indicators relevant to acetylene generation quality, including phosphine and hydrogen sulfide limits if required by buyer specifications.
Confirm whether third-party inspection, pre-shipment sampling, and SGS/CCIC testing can be arranged for the lot being shipped.

Questions to confirm
Can you confirm CAS 75-20-7, CaC2 grade, and the exact specification sheet for the offered lot?
What gas yield is guaranteed for each particle size, and what test method or standard is used?
What are the CaC2 content, particle size distribution, dust/fines percentage, and batch tolerance?
Can you provide limits or test data for phosphide/phosphine-related and sulfide/hydrogen sulfide-related impurities if required for acetylene use?
Is the offer for 50 kg drums, 100 kg drums, or both, and are drums new, sealed, labeled, and DG-compliant?
Can you provide SDS, COA, DG declaration, packing certificate, commercial invoice, packing list, certificate of origin, and bill of lading draft before shipment?
What is the MOQ, monthly available quantity, lead time after deposit or L/C, and validity period of the quotation?
Which China port is proposed, and can you quote FOB, CFR, or CIF India with DG freight availability confirmed?
