The Thai banking laws are very strange and do seem to vary from bank to bank as well just to keep it interesting. Strictly the currency regulations are as follows:

Outward Transfers
Required Documents

Supporting documents indicating purpose of transfer.
If currency amount > US$ 10,000 or equivalent and for non-merchandise:
Thor Tor 4 Kor (ข) form for Non-resident customers or,
Thor Tor 4 Gor (ก) for resident customers is also required.
Money Laundering Report Form (You must include your Tax ID or other identification)
Cash transactions > Bt 2,000,000 require a PorPor Ngor. 1-01 form
Asset transactions (ex: telex transfer) > Bt. 5,000,000 require PorPorNgor 1-02 form

Now the word non-merchandise interests me.

Best of luck
