Sourcing FAQ

How do I confirm a supplier is an actual manufacturer and not a reseller?
Ask for factory photos, capacity details (foundry/machining), OEM/ODM statements, and factory inspection or third-party audit reports; manufacturers commonly show 'we manufacture' or 'factory' on their own site.
What certifications should I expect for fire sprinkler fittings?
Commonly requested certifications are UL and FM approvals for fire protection markets, plus relevant national standards (GB/T, EN, ISO) and material test certificates; request copies before bulk orders.
What are typical lead-time drivers for these fittings?
Lead time depends on material sourcing, casting/machining queue, certification testing, coating/galvanizing steps and order quantity—larger or customized runs and UL/FM testing add time.
What minimum order quantities (MOQs) should I expect?
MOQs vary widely by factory and item complexity; simple stock items may have low MOQs while custom castings or UL/FM-approved items often require higher MOQs—ask suppliers for per-item MOQs in writing.
