Hi again raraz,
Link hidden: Login to view is not a supplier rather they are like a portal for sellers and buyers - its a place where you can post buyer leads and suppliers will contact you or where you can scout for suppliers for products that you might be interested in. They offer suppliers for also any product you can think of. But please note that although their main office is in Hong Kong majority of their suppliers are from mainland China, so do stay away from suppliers offering brand name products.
Hong Kong Trade Development Council is like an online directory for Chinese manufactures. This site can be a gold mine, but it'll be hard telling which supplier is good and which ones are not-so-good. I tried randomly clicking trough the different categories and saw that most suppliers accept only T/T payments - which is not very ideal especially if you are not familiar with the supplier.
Hope this helps. All the best! :)
