🪨 Whetstones & Hand Grinders (Millstones, Grindstones, Grinding Wheels, etc.)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy
📌 I. Product Definition & Classification: Do You Really Know "Whetstones"?

Whetstones and hand grinders are essential tools for sharpening, polishing, trueing, or cutting. In international trade, these products are classified under Chapter 68 (Articles of Stone or Similar Materials). The critical distinction lies in the material composition and specific use:

Hand Sharpening/Polishing Stones: Specifically designed for manual sharpening of knives, tools, or polishing surfaces.
Other Millstones/Grindstones: Used for grinding purposes, potentially for industrial or mechanical applications, but without frameworks.

⚠️ Key Classification Distinction:
- If the product is specifically a "Hand sharpening or polishing stone" → It falls under 6804.30.00.00.
- If the product is an "Other millstone, grindstone, or grinding wheel" made of Natural Stone → It falls under 6804.23.00.00.
- Note: Products made of agglomerated abrasives or ceramics may fall under other subheadings not listed in this specific data set, but based on the provided , we focus on Natural Stone variants.

📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)

🔍 Key Reminder:
- 6804.30.00.00 is a specific subheading for "Hand sharpening or polishing stones", which may include materials other than just natural stone (e.g., synthetic abrasives).
- 6804.23.00.00 is a specific subheading for millstones/grindstones of Natural Stone, which may not necessarily be for "hand sharpening" but for broader grinding purposes.
- Misclassification Risk: Declaring a natural stone whetstone as "Hand sharpening stone" (6804.30) vs. "Other millstone of natural stone" (6804.23) leads to vastly different tax implications.
