FAQ
1. MOQ:2000pcs each shipment,however more quantity can low its cost of transportation and customs fee.
2. Lead-time:normally 30-45days after PI confirms/deposit date.
3. Quality assurance :we apply advanced management of IATF16949 to guarantee the stability and consistency.
4. Price term:Normally CIF term,but we are okay to do other terms like FOB/EX-work/C&F/DDU ect.
5. Mode of transportation: sea freight is the most usual way ,for urgency,airway shipment can arranged accordingly.
6. Production period:normally one bearing would take around 10-30 steps on process from turning，Grinding，Super grinding，demagenization ，Semi-parts washing，Matching，Assembly，Grease injection，Shield/seal Press，Vibration\BVT testing，Appearance inspection，Packing ect,So it would take 30-45days for common items.
7.Transportation is fast and easy to manage as Ningbo DAZ location nears Shanghai/Ningbo seaport.
