1. You have to check data availability of Thailand. Type "thailand" on the "search for box". In the result page, click data availability
2. In the data availability page, it is organized by commodity classification and year. If you need data from 2002-2006, use HS02.
3. Go to basic selection:
- select HS02 classification
- type "beer" on the commodity box
- type "thailand" on the reporter box
- select "import" on trade flow selection
- Click advanced items, and select Sort Order : "TradeVal" --> means that it will be sorted by trade value
- Click Sumit
4. Note, you will get two HS02 codes: 2203 and 220300. They both have the same meaning, so that you can ignore one of them.
