π© Grinding Heads & Abrasive Tools (Industrial & Handheld)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategy
π I. Product Definition & Classification: What Exactly is a "Grinding Head"?
The term "Grinding Head" is a broad industrial descriptor. In international trade, it is not a single HS Code but rather a functional description that splits into three distinct categories based on composition, power source, and integration.
Misclassification here is the #1 cause of customs delays, as US Customs and Border Protection (CBP) strictly distinguishes between: 1. Standalone Abrasives: The actual grinding material (stones, wheels, discs). 2. Power Tools: Handheld devices with motors that use the abrasives. 3. Interchangeable Tool Parts: Metal bases or shanks designed to hold abrasive inserts.
β οΈ Critical Distinction Point:
- Is it just the abrasive material (stone/ceramic)? β Chapter 68
- Is it a powered tool (drill/grinder with motor)? β Chapter 84
- Is it a metal part holding the abrasive? β Chapter 82
π¦ II. HS Code Classification Details (Based on Provided Data)
Below are the 6 specific HS Codes derived from your input data, categorized by product type.
π·οΈ Category A: Standalone Abrasive Tools (No Framework/Motor)
These are raw grinding materials or wheels without any motor or handgrip framework.
| HS Code | Product Description | Material | Tax Rate (Total) |
|---|---|---|---|
6804.22.60.00 |
Millstones, grindstones, grinding wheels... Of other agglomerated abrasives or of ceramics | Agglomerated Ab./Ceramic | 25.0% |
6804.22.40.00 |
Millstones, grindstones, grinding wheels... Abrasive Wheels | Agglomerated Ab./Ceramic | 25.0% |
π Explanation:
- These codes apply to standalone grinding wheels, whetstones, or polishing stones.
- "Abrasive Wheels" (.40.00) vs. "Other" (.60.00):.40.00is specifically for wheel-shaped abrasives. If the shape is irregular or not a standard wheel, it falls under.60.00.
- Composition: Must be natural stone, agglomerated natural/artificial abrasive, or ceramics.
π·οΈ Category B: Powered Handheld Tools
These are complete tools with self-contained motors (electric, pneumatic, hydraulic).
| HS Code | Product Description | Type | Tax Rate (Total) |
|---|---|---|---|
8467.29.00.35 |
Tools for working in the hand, pneumatic, hydraulic or with self-contained electric... Other Grinders, polishers and sanders: Other | Hand Grinder/Polisher | 7.5% |
π Explanation:
- This code is for complete handheld grinders (e.g., angle grinders, die grinders, bench grinders with motors).
- It does not include the abrasive consumable itself, but the machine that uses it.
π·οΈ Category C: Parts of Powered Tools
Spares and replacements for the machines in Category B.
| HS Code | Product Description | Type | Tax Rate (Total) |
|---|---|---|---|
8467.99.01.90 |
Tools for working in the hand... Parts: Other Other | Hand Tool Parts | 25.0% |
π Explanation:
- This covers spare parts for powered grinders (e.g., motor casings, arbor adapters, replacement switches).
- β οΈ High Tax Alert: This part is taxed at 25%, not the 7.5% of the main tool.
π·οΈ Category D: Interchangeable Metal Tools/Parts (Base Metal)
These are metal shanks, bases, or inserts for machines or hand tools, NOT the abrasive material itself.
| HS Code | Product Description | Sub-Category | Tax Rate (Total) |
|---|---|---|---|
8207.90.75.85 |
Interchangeable tools... base metal parts thereof... Other: Other: Not suitable for cutting metal | Non-Metal Cutting Tool Part | 28.7% |
8207.90.30.85 |
Interchangeable tools... Cutting tools containing >0.2% Cr, Mo, W or >0.1% V | Alloy Steel Cutting Part | 30.0% |
π Explanation:
- "Grinding Head" often refers to the metal shank that holds the grinding stone in a rotary tool.
-.75.85: For parts that do not cut metal (e.g., for wood, stone, or polishing).
-.30.85: For parts made of high-alloy steel (containing Chromium, Molybdenum, Tungsten, or Vanadium) used for cutting.

π οΈ IV. Customs Clearance Practical Advice (Pitfall Avoidance Guide)
β 1. Documentation Checklist (Non-Negotiable)
| Document | Requirement | Why It Matters |
|---|---|---|
| β Product Specs | Must specify: Material (Ceramic/Agglomerated), Shape (Wheel/Block), Dimensions, Binding Agent. | CBP needs to distinguish 6804.22.40 (Wheel) from 6804.22.60 (Other). |
| β Photos | Clear shots of the item without the motor/tool. If it's a head, show the metal shank + abrasive insert separately. | Prevents misclassification as a "Power Tool" or vice versa. |
| β Composition Statement | For 8207.90 codes: Must declare % of Chromium, Molybdenum, Tungsten, or Vanadium. |
Determines if you pay 28.7% or 30.0%. |
| β Commercial Invoice | Describe as: "Ceramic Grinding Wheel, Model X" OR "Die Grinder, Electric, Model Y" | Avoid vague terms like "Grinding Head" alone. Use specific technical names. |
| β HTS Declaration | Explicitly state the 10-digit HTS code on the invoice. | Reduces CBP query time. |
β 2. Classification Strategy & Tips
π₯ Rule of Thumb:
"If it has a motor, it's Chapter 84. If it's just the stone, it's Chapter 68. If it's the metal shank, it's Chapter 82."
| Scenario | Correct HS Code | Common Mistake | Consequence |
|---|---|---|---|
| Standalone Ceramic Wheel | 6804.22.40.00 |
Classifying as "Tool Part" (8207) |
Overpaying duty (25% vs 30% base) & documentation complexity. |
| Angle Grinder (Tool) | 8467.29.00.35 |
Classifying as "Part" (8467.99) |
Overpaying! Parts are 25%, Tools are 7.5%. |
| Grinding Head (Metal Shank) | 8207.90.75.85 |
Classifying as "Abrasive" (6804) |
Underpaying! CBP will assess back-duties + penalties. |
| Set: Tool + Wheels | Declare Separately | Lump Sum Declaration | CBP may reject the lump sum. Declare each item by its nature. |
β 3. Special Handling for "Grinding Heads"
-
Is it a "Head" or a "Wheel"?
- If it is a wheel (flat, cylindrical, or cup-shaped) used for grinding surfaces β
6804.22. - If it is a rotary burr or shank-mounted abrasive β It may still be
6804if the abrasive is the main value, OR8207if the metal shank is the primary component. Check value composition.
- If it is a wheel (flat, cylindrical, or cup-shaped) used for grinding surfaces β
-
Alloy Content Matters:
- For
8207.90.30.85, you must provide a mill certificate or test report showing the alloy content (Cr, Mo, W, V). Without this, CBP may default to the higher tier or demand extensive testing.
- For
-
De Minimis ($800 Rule):
- For shipments under $800 (Section 321): Duties are generally $0, but risk of inspection is HIGH for Chapter 68 and 82 items due to anti-dumping concerns. Ensure documentation is perfect.
- For shipments over $800: Duties are mandatory and strictly enforced.

π VI. Common Errors & Red Flags
β Error 1: Declaring a Powered Grinder as "Grinding Head" to hide the motor.
π Result: CBP inspects, finds the motor, reclassifies to 8467.29.00.35. You pay 7.5% instead of potentially misdeclaring as a cheap part. Penalty risk.
β Error 2: Mixing Standalone Wheels with Powered Tools in one line item. π Result: Customs rejects the entry. Must split invoices. Delay in clearance.
β Error 3: Ignoring Alloy Content for 8207.90.30.85.
π Result: CBP assumes highest alloy content or applies general duty. Unexpected $30% duty.
β Error 4: Using vague descriptions like "Grinding Accessories." π Result: CBP issues a "Request for Information" (RFI) within 48 hours. Clearance delayed by 1-2 weeks.
β Best Practice Declaration Example:
"Ceramic Grinding Wheel, 4-inch diameter, agglomerated abrasive bond, for surface grinding, Model ABC-123. HTS: 6804.22.40.00"
π― VII. Conclusion: Optimize Your Tariff Strategy
π― Key Takeaways:
πΉ Power Tools (
8467) are cheapest at 7.5% duty.
πΉ Standalone Abrasives (6804) are mid-tier at 25% duty.
πΉ Metal Parts/Alloy Heads (8207) are most expensive at 28.7% - 30.0% duty.
πΉ Always declare separately. Do not lump tools, parts, and consumables together.
π Pro Tip:
If you are exporting "Grinding Heads" that are actually metal shanks with bonded abrasive, carefully evaluate if the metal value or abrasive value dominates. If the abrasive is removable, classify as 6804. If it is a fixed metal base, classify as 8207. This single decision changes your duty by ~3-5%.

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
