What is your delivery time?
It depends. If we have bulk goods in stock, we can ship goods within 3 days after the QC process. If we don't have stock, normally it takes 7-15 days for OEM samples and 20-30 days for bulk goods. If it refers to opening the new mold, it takes an extra 7-15 days to make the mold.
What are your payment terms?
Normally, we make a 30% deposit after PI confirmation and a 70% balance before shipment.
How do you guarantee good quality?
A pre-bulk sample check can solve this problem to the largest extent. We will arrange production according to the pre-bulk sample quality standard after your confirmation of the samples.
