FAQ
Q: Are you trading company or manufacturer ?
A: Our company is a professional manufacturer of magnets and magnetic assemblies .
Q: Exact Quotation?
A: Before our exact quotation, we need confirm the Size , Grade, Coating, Magnetization Direction and Quantity , all of these factors will affect the price
Q: Do you provide samples ? is it free or extra ?
A: We think sample test is necessary for first order, we could offer the sample for free charge but do not pay the cost of freight.
Q: How long is your delivery time?
A: Generally it is 5-10 days if the goods are in stock. or it is 15-20 days if the goods are not in stock, it is according to quantity.
