HTS codes secure a 10-digit code like 8542.31.0010, where the code number itself is information, but TariffRate secures percentage values like 0%, 25%, 50%, where the number is information.
I requested Sequential Thinking. 'What is important in tariff rate collection?’
Claude explained. "1st thought: Tariff rates change according to policy.", "3rd thought: When a new policy is announced, tariff rates can change.", "5th thought: Therefore, we need to find policy changes.”
"7th thought: TariffRate requires policy tracking.", "10th thought: We need to record the implementation date for each change.”
The important thing was to collect policy changes.
While investigating tariff rates, I discovered something else. Tariffs were not just one type. There were multiple tariff types. Each type was calculated separately.
Why are there multiple types? I requested Sequential Thinking. 'Why are there multiple tariff types?’
