I apologize about my late reply. Now I'm creating draft for declaration letter about your product and accessories. I follow the instructions from Thai FDA's staff. There are many products and accessories, I try to fill all details completely.
During I'm checking the name of the product and code match with your catalogue. The GH wall bracket end end-mounted rail: Code No.550451 and GH wall bracket end side-mounted rail: Code NO.550451 have a same code in catalogue. So, please describe me that are same product or wrong code. If it's mistake, please send the correct catalogue to me via email.
If I finish and check all details are matched with your catalogue. I'll send the letter's draft to you. Please print out with your company letter and send the document to Chamber of commerce, the Association or Notary public to 'certify true and correct contents'. Then, the document must legalized by the Royal Thai embassy before sending it to me.
