π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy
π 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.
β οΈ Key Classification Distinction:
- If the product is specifically a "Hand sharpening or polishing stone" β It falls under 6804.30.00.00.
- If the product is an "Other millstone, grindstone, or grinding wheel" made of Natural Stone β 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.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | Material Type |
|---|---|---|---|
6804.30.00.00 |
Millstones, grindstones, etc., for grinding/sharpening/polishing/truing/cutting; Hand sharpening or polishing stones | Manual knife sharpening, tool polishing, artisanal grinding | Natural Stone, Agglomerated Abrasives, or Ceramics |
6804.23.00.00 |
Millstones, grindstones, grinding wheels, etc., Of Natural Stone | Grinding stones made entirely of natural stone (e.g., whetstones, grindstones) | Natural Stone Only |
π 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.
π° III. 2026 Latest Tariff Rate Details (Including Additional Taxes)
β Applicable Country: United States (US)
β Origin: China (CN)
β Effective Date: As per provided data (Current 2026 Context)
π― 1. 6804.30.00.00 ββ Millstones, etc., for grinding/sharpening/polishing/truing/cutting; Hand sharpening or polishing stones
| Item | Detail |
|---|---|
| Base Tariff | 0.0% (ad valorem) |
| Additional Tariff (Section 301) | +25.0% |
| Total Tax Rate | 25.0% |
| Tax Calculation | CIF Value Γ 25% |
| De Minimis Exemption | β Not Applicable (Section 301 tariffs generally apply to all imports, regardless of value, unless specifically exempted) |
| Legal Basis | USHTS 2026, Chapter 68, Heading 6804, Subheading 6804.30.00.00; Section 301 Tariff List |
π Explanation:
- This category attracts a 25% additional tariff due to Section 301 measures on Chinese goods.
- Although the base tariff is 0%, the additional tax makes the effective rate 25%.
- This applies to all hand sharpening/polishing stones, regardless of material (natural, agglomerated, or ceramic), as per the description.
π― 2. 6804.23.00.00 ββ Other millstones, grindstones, grinding wheels, etc.: Of Natural Stone
| Item | Detail |
|---|---|
| Base Tariff | 0.0% (ad valorem) |
| Additional Tariff (Section 301) | 0.0% |
| Total Tax Rate | 0.0% |
| Tax Calculation | CIF Value Γ 0% = $0 |
| De Minimis Exemption | N/A (No tax to apply) |
| Legal Basis | USHTS 2026, Chapter 68, Heading 6804, Subheading 6804.23.00.00 |
π Important Note:
- This category has ZERO additional tariff under Section 301.
- The key condition is that the product must be exclusively made of natural stone and fall under "Other millstones, grindstones, grinding wheels" (not specifically classified as "Hand sharpening stones" if they are broader industrial grindstones).
- Strategic Advantage: If your product is a natural stone grindstone and can be classified under 6804.23.00.00, you save 25% in tariffs compared to 6804.30.00.00.
π οΈ IV. Customs Clearance Practical Advice (Combat-Ready Pitfall Avoidance)
β 1. Required Documentation Checklist (All Essential)
| Document | Required? | Description |
|---|---|---|
| β Product Specification Sheet | βοΈ | Must detail material (Natural Stone vs. Agglomerated/Ceramic), dimensions, and intended use (Hand sharpening vs. General grinding). |
| β Product Photos | βοΈ | Clear images showing the stone, label, and any packaging. Must clearly indicate if it's a "Hand sharpening stone" or a general "Grindstone". |
| β Commercial Invoice | βοΈ | Must accurately describe the goods. Avoid vague terms like "Stone Tool"; use precise HS Code descriptions. |
| β Packing List | βοΈ | Weight and volume details. Ensure no mixed shipments that could confuse classification. |
| β Certificate of Origin (CO) | βοΈ | Proves origin as China. Required for verifying applicability of Section 301 tariffs. |
| β Material Composition Statement | βοΈ | Critical for distinguishing between 6804.30 (any material) and 6804.23 (Natural Stone Only). |
β 2. Declaration Tips (Key Mnemonic)
π₯ βNature Stone Zero Tax, Hand Stone Twenty-Five! Classify Right, Stay Alive!β
| Scenario | Correct Declaration | Wrong Action | Consequence |
|---|---|---|---|
| Natural Stone Grindstone (for industrial/general grinding) | 6804.23.00.00 |
Declare as "Hand Sharpening Stone" | Unnecessary 25% tax |
| Hand Sharpening Stone (even if natural stone) | 6804.30.00.00 |
Declare as "Other Millstone" | Risk of Misclassification Penalty + Potential 25% tax if corrected later |
| Agglomerated Abrasive Whetstone | 6804.30.00.00 |
Declare as "Natural Stone" | False Declaration + Heavy Penalties |
| Ceramic Grinding Wheel | 6804.30.00.00 |
Declare as "Natural Stone" | False Declaration + Heavy Penalties |
π Critical Distinction:
- If the product is specifically for hand sharpening or polishing, it MUST go to 6804.30.00.00, regardless of material.
- If the product is a millstone/grindstone made of natural stone but NOT specifically for hand sharpening/polishing (e.g., for grinding grains or industrial abrasion), it MAY qualify for 6804.23.00.00 (0% tax).
- Ambiguity Check: If the product is a natural stone whetstone used for hand sharpening, customs may still classify it under 6804.30.00.00 because of the "Hand sharpening" clause. To get 0% tax, ensure the product is not marketed or used specifically as a "hand sharpening stone" but as a general "natural stone grindstone/millstone".
β 3. Special Cases Handling
| Situation | Handling Advice |
|---|---|
| Mixed Material Stones (e.g., natural stone core with ceramic coating) | Declare based on principal material. If natural stone is dominant and function is grinding, argue for 6804.23.00.00. |
| Set of Whetstones (e.g., coarse + fine) | Declare as a single unit if packed together for retail. Classification depends on the primary function (Hand sharpening β 6804.30.00.00). |
| Industrial vs. Hand Use | Provide Technical Data Sheets proving industrial use (e.g., mounting holes, rotational speed specs) to support 6804.23.00.00 if applicable. |
| New Material Innovations | If made of new agglomerated abrasives, always default to 6804.30.00.00 unless specifically excluded. |
π V. Global Market Comparison (2026 Latest)

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
