FAQ

Q1: Can I have a sample order for Neodymium magnet? 
A: Yes, we welcome sample order to test and check quality. Low MOQ of 1PC for sample checking is available.Mixed samples are acceptable. Please cover the freight.

Q2: What about the lead time? 
A:Sample needs 3-5 days, mass production time needs 15~30 days for each order in general.
 
Q3: How do you ship the goods and how long does it take to arrive? 
A: We usually ship by DHL, UPS, FedEx or TNT. It would take around 3-5 days to arrive. Airline and sea shipping are also available. 
 
Q4: Is it OK to print my logo on magnet product or package? 
A: Yes. Please inform us formally before the production and confirm the design firstly based on our sample. 
 
Q5: How are Neodymium Magnets made?
A: The main ingredients are Neodymium, Iron and Boron. The exact ingredients depend on the grade being produced. We also add a key ingredient called dysprosium to raise the coercivity of the material and increase the resistance to demagnetisation and corrosion. You can read more about the manufacturing process in our company website, www.hawellmagnetics.com.
 
Q6: How do you make our business long-term and good relationship? 
A: We keep good quality and competitive price to ensure our customers' benefits. We respect every customer as our friend and we sincerely do business and make friends with them, no matter where they come from.
