𧱠Whetstones (Grinding & Polishing Stones)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
π 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.
β οΈ 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. β 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.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority Reference)
| HS Code | Product Description | Applicable Scenario | Material Type | Framework? |
|---|---|---|---|---|
6804.30.00.00 |
Hand sharpening or polishing stones | Knife whetstones, manual tool sharpening stones, precision polishing stones | Natural stone, agglomerated abrasives, or ceramics | β No framework |
6804.23.00.00 |
Other millstones, grindstones, grinding wheels: Of natural stone | Industrial millstones, large natural stone grinding wheels, non-hand-sharpening stones | Natural stone only | β No framework |
π Important Reminder:
- Hand sharpening stones (even if made of natural stone) are explicitly separated from other natural stone millstones. If itβs 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.

β 2. Declaration Tips (Key Mantra)
π₯ "Hand Use = 25%, Industrial Natural Stone = 0%, Misclassification = Penalty!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Knife sharpening stone (natural or abrasive) | 6804.30.00.00 (25%) |
Misdeclare as "natural stone millstone" β 0% (illegal, risk of penalty) |
| Large natural stone grinding wheel (industrial) | 6804.23.00.00 (0%) |
Misdeclare as "hand sharpening stone" β 25% (overpay) |
| Ceramic-based sharpening stone | 6804.30.00.00 (25%) |

π VI. Common Errors & Pitfall Avoidance Guide (Blood-Tested Lessons)
β Error 1: Declaring a hand sharpening stone as "natural stone millstone" to avoid 25% tax
π Consequence: Customs audit β penalty, back taxes, and possible seizure
β Error 2: Declaring an industrial natural stone millstone as "hand sharpening stone"
π Consequence: Overpay 25% tax unnecessarily β cost inflation
β Error 3: Omitting material composition (natural vs. agglomerated vs. ceramic)
π Consequence: Customs delay for reclassification β demurrage fees
β Error 4: Using vague terms like "grinding stone" without specifying hand use
π Consequence: Customs may assign 6804.23.00.00 (0%) or 6804.30.00.00 (25%) based on interpretation β uncertainty
β Correct Declaration Example:
"Whetstone, Hand Sharpening Stone, Natural Stone, 100x50x20mm, Model WS-100, Intended for Manual Knife Sharpening"
π― VII. Conclusion: Precise Classification Saves Money, Time, and Stress!
π― Remember the Mantra:
πΉ "Hand Sharpening = 25%, Industrial Natural Stone = 0%, Misclassification = Penalty!"

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
