When I bought it from your shop what you claim is I can send in to Asus Singapore as long as it can be fixed locally (e.g. parts that are similar to the WIFI version). If it is due to other non similar parts like the LTE issue then need to send back to Google/USA by your shop (shipment fee buyers pay).
So which is which? Perhaps when you sell something, your supplier or yourself should make it clear for us buyers, so there would not be misunderstanding. Reputation very important for doing business, but you have been doing well so far so I hope the practices by Asus that can service stays. We are simply concerned about uncertainties (e.g. not legally binding warranty)
