As a guy who had been working for D*G/D*S in China, and N*X in Vietnam,
Maybe i can give some advice.
a,preparation, Both you and your partner need FDA reg number for custom clearance.
It's not complicated for a US lab to register FDA, in 2020 FDA charge 5236 USD for annual fee, and would increase a little bit in every year. You should concern this in spending.
b, the turn around time normally would be 7-10 days (shipping by UPS/FEDEX),
2 days transport from US to Asia , 3~4 days productive time,1 day transport from Asia to US, and 1 day preparing shipment and invoice to clinic. May need 1~2 more days if you want double check the production.
For international trading i suggest you to use UPS, Fedex has trouble frequently in custom clearance. But for domestic transport, UPS is crappy.
c, About the transport fee,
there is no advantage to do outsourcing if you have only sevral cases in every shipment. When the quantity rise to 20 case ,the transport fee will reduce to 3~5 USD per every case. The big net lab groups could have 800~2000 cases in every parcel, and the transport cost would as low as 1 USD per case.
Usually 7-8 fixed case weight 1kg, 2-3 removable cases weight 1kg. You can make calculating by your self.
d,The general price you would receive.
15-25USD for PFM
30-40USD for full contour Zr
40-55USD for layered Zr or E-max
30-50USD for Arcylic denture
20-40USD for Co Cr framework
I suggest that don't only search for low price,
steady quality and delivery on time are more important.
It's not so easy like 2010s to do outsourcing business in the traditional way nowadays, but still could earn margins if you are good in operating.
Many outsourcing net labs start investing in mill centres, which could save turn around time, and made in USA!
Hoping This Helps
