Quick answers

The things buyers ask most when getting in touch. More in our full FAQ.

How fast will you reply?
Within 24hrs, often the same day during our hours (Mon–Sat, 9:00–18:00 GMT+8). To speed things up, include dimensions, grade or operating temperature, coating, and quantity.
Is there a minimum order?
No — there's no MOQ on custom orders. You can start with a single prototype and scale the same spec into production later. See the ordering process →
Not sure which grade or spec you need?
That's fine — send your application and we'll recommend the grade, coating, and magnetization. Or try the grade selector first.
Do you ship to my country?
Yes — we ship worldwide, FOB Hong Kong, Shenzhen, or Zhuhai, with RoHS/REACH and export documentation prepared as needed.
