FAQ:
Q: Are you a manufacturer?
A: Yes, Our factory was founded in 1999. We are an experienced manufacturer of foundry ceramic sand.
Q: What are the key quality indexes of ceramic foundry sand?
A: First of all, the Al2O3 content. We have three grade:75% Al2O3 ceramic sand,73% Al2O3 ceramic sand,70 Al2O3 ceramic sand.
Secondly, the particle size distribution of ceramic sand. We will provide samples according to the customer’s requirements. And make the same particle percentage coincide with confirmed sand.
Q: Where is the nearest port from your factory?
A: Qingdao and Tianjin are both near to us.
Q: What is the HS code of ceramsite sand?
A: Since there is no specific HS code for ceramsite sand, there are HS codes 69149000 and 68159990 suitable for exporting ceramsite sand. But with our experience, HS code 68159990 is easier to do custom clearance with no risk to be inspected.
Q: How do you operate the QC system?
A: Before shipment, we will take 1 day to check the chemical composition for every bag. Our QC staff will take another day to check particle size distribution for every bag. We will reserve samples from each batch production in case there is anything wrong.
Q: What is the lead time for each order?
A: It depends on the quantity and sand size required. Generally 5-10 days for FCL（20-25MT）.
