Thanks for this. Unfortunately no local companies stock Toto products, even though North America, EU, Thailand, HK, Singapore, Korea etc all stock these.
This product should be wired and grounded correctly as it's a Malaysian made product for the Thai market, they produce the same product for Singapore and other countries as well. They have similar devices on sale in the European Union as well. Majestic Home is listed on the
official Toto website as an authorised reseller and Toto Japan would probably not put their name next to a dodgy product. Anyhow I've contacted the manufacturer's Thai division and the global one to see if they can help a tourist who returned with one such device with what you mentioned in anticipation of any pedantry from our customs. I've previously had some success with Japanese companies who sometimes help a foreign customer out, so I could try that next. I really don't see why SARS would be doing that given that the item is not for resale. Why is SARS concerned about what I install at home or not install. I suppose I could be buying this for educational purposes for disassembly to figure out how the thing works.
I have one such device from Hyundai WacorTech in Korea and the PCB is sealed in clear silicon. These are safe devices.
Anyhow AGS responded today with this:
Also why would AGS ask me to get an invoice with EXW? I mean they are the actual agents, AGS is an intermediary for companies which DON'T EXPORT. Surely they should be doing that?
About the ID number, I did not provide an importer's code this time so hopefully it's still on my ID number. I did not provide an ID number at all as far as I know. Maybe when I created the AGS account.
