🧱 Whetstones (Grinding & Polishing Stones)

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

Whetstones (also known as grinding stones, millstones, or sharpening stones) are essential tools for grinding, sharpening, polishing, truing, or cutting materials. In international trade, they are classified based on their material composition and function. The key distinction lies between hand sharpening/polishing stones and other millstones/grinding wheels.

⚠️ Key Distinction Points:
- Hand sharpening/polishing stones: Specifically designed for manual use (e.g., knife sharpening, tool maintenance). Often made of natural stone or agglomerated abrasives. → HS 6804.30.00.00
- Other millstones/grinding wheels: Includes industrial grinding wheels, large-scale millstones, or stones not specifically for hand sharpening. If made of natural stone, they fall under HS 6804.23.00.00.
- Material Matters: Stones made of agglomerated natural/artificial abrasives or ceramics may fall under different subheadings depending on their specific structure and framework status.

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

🔍 Important Reminder:
- Hand sharpening stones (even if made of natural stone) are explicitly separated from other natural stone millstones. If it’s intended for hand use, classify under 6804.30.00.00.
- Other natural stone millstones (not for hand sharpening) fall under 6804.23.00.00.
- Agglomerated abrasives or ceramic-based stones used for hand sharpening also fall under 6804.30.00.00, provided they are without frameworks.
