First Problem: How to Classify Types

To create a new checklist, I decided to refer to HTS_Checklist.md. I requested structure understanding with Sequential Thinking.

I proceeded exactly the same up to the "STEP 0: Read Product_Article.md" part in PART A. Now I had to write STEP 1.

In Week 16, I learned that there are multiple tariff types, but how do I classify them? How do I determine which type it is when reading documents? I requested Sequential Thinking. 'How do we distinguish tariff types?’

Claude answered. "1st thought: Each document will specify the type.", "3rd thought: There will be separate sections for each type.", "5th thought: While reading the document, we can check the type and record each.”

"7th thought: We can create 'Type A:', 'Type B:', 'Type C:' fields for each product.", "10th thought: We just fill in the applicable types. We leave empty the types that don't exist.", "12th thought: We need to add this to STEP 0.”

I understood this. I needed to create type-specific fields for each product. When copying the Product list in STEP 0, we create Type A, B, C fields together.

I modified the STEP 0 procedure. I decided to add the following fields under each product. Formats like "Type A:", "Type B:", "Type C:". They are empty at first, and we will fill them in as we search.

I decided to reflect this modified procedure in the prompt. STEP 0 will increase to about 180 lines. Because type classification field descriptions are added.
