FAQ

Q: What is the standard packaging configuration for commercial orders?

A: Material is packed in 25 kg fiber drums with dual-layer polyethylene inner liners to reduce moisture ingress during transit.

Q: What is the Minimum Order Quantity (MOQ) and standard production lead time?

A: The standard MOQ is 500 kg, with typical production and dispatch lead times of 14–21 days.

Q: Which Incoterms and shipping ports are primarily utilized for international logistics?

A: Shipments are handled under FOB, CFR, or CIF terms via major ports including Shanghai and Qingdao.

Q: How does the factory manage bulk cargo shipping risks to overseas destinations?

A: Palletized shipments are secured with industrial strapping and moisture-barrier overwraps, supported by standard international freight forwarding procedures.

Q: Is it possible to customize the mesh size or bulk density of the powder?

A: Particle size and bulk density can be adjusted through milling and processing parameters according to specification requirements.
