📌 I. Product Definition & Classification: What Exactly Is a "Ring Size Ruler"?

A Ring Size Ruler (also known as a ring sizer, ring mandrel, or sizing gauge) is a specialized instrument used in the jewelry industry to determine the circumference or diameter of a finger for accurate ring fitting.

In international trade, these products are strictly classified under Chapter 90 ("Optical, photographic, cinematographic, measuring, checking, precision, medical or surgical instruments and apparatus") because they are instruments for measuring length, for use in the hand.

⚠️ Key Distinction:
- If it is a physical tool (metal, plastic, or paper gauge) used for manual measurement → It falls under 9017.30 (Measuring instruments).
- If it is a digital electronic device with a screen/display → It may fall under 9031.80 (Other measuring/checking instruments), but standard ring sizers are mechanical.
- If it is merely a template without precise measuring scale → It might be considered a "part" or accessory, but usually, the ruler itself is the main article.
