π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Clearance Strategy
π I. Product Definition and Classification: Do You Really Understand "Cylinder Block Grinding"?
A Cylinder Block Grinding Machine is a precision metalworking tool designed to finish the cylinders of engine blocks. In international trade, its classification depends heavily on its working principle (grinding vs. honing/lapping) and configuration (numerical control, internal/external cylindrical).
According to the provided <DATA>, these machines fall under two main categories:
1. Numerically Controlled (NC/CNC) Grinding Machines (Heading 8460.24): High-precision, automated finishing.
2. Parts and Accessories (Heading 8466.93): Castings, weldments, and fabrications specifically for grinding machines.
β οΈ Key Distinction Point:
- If the machine performs grinding using grinding stones/abrasives and is NC-controlled β It falls under 8460.24.00.
- If the machine performs honing, lapping, or polishing (finishing by means other than grinding) β It may fall under 8460.30 (not listed in<DATA>, so excluded here).
- If the item is a part/accessory (e.g., bed, base, castings) β It falls under 8466.93.
π¦ II. HS Code Classification Details (Based on Provided <DATA>)
| HS Code | Product Description | Application Scenario | Tax Status in <DATA> |
|---|---|---|---|
8460.24.00.10 |
Other grinding machines: NC, Other: External cylindrical, including universal | Grinding the outer diameter of cylinder liners or bores; universal grinding for various cylindrical surfaces. | β Failed to retrieve tax info |
8460.24.00.30 |
Other grinding machines: NC, Other: Internal cylindrical | Grinding the inner cylinder bore of engine blocks; precision internal finishing. | β Failed to retrieve tax info |
8466.93.53.40 |
Parts/accessories for machines 8456-8461: For 8460-8461: Bed, base, table, etc., of metal: Other: Of metalworking machine tools for grinding or finishing gears | Castings, weldments, or fabrications (beds, bases, frames) used in gear grinding/finishing machines. | β Base: 0.0%, Additional: 0.0% (Total: 0.0%) |
8466.93.98.40 |
Parts/accessories for machines 8456-8461: For 8460-8461: Other: Other: Other: Of metalworking machine tools for grinding or finishing gears | Other parts/accessories not listed above, specifically for gear grinding/finishing machines. | β Base: 4.7%, Additional: 25.0% (Total: 29.7%) |
π Important Note:
- The descriptions for HS Codes8466.93.53.40and8466.93.98.40explicitly mention "grinding or finishing gears".
- β οΈ Critical Compliance Risk: If your "Cylinder Block Grinding Machine" is actually for engine cylinders (not gears), declaring it under8466.93(which specifies gears) may lead to misclassification penalties. Ensure the part is indeed for gear machines if using these codes.
- For actual cylinder block machines,8460.24.00.10(External) and8460.24.00.30(Internal) are the correct machine classifications, but tax data was not retrieved.

π οΈ IV. Customs Clearance Practical Advice (Battle-Tested Pitfall Avoidance Guide)
β 1. Documentation Checklist (All Required)
| Document | Required | Description |
|---|---|---|
| β Product Specification Sheet | βοΈ | Must clearly state: "Cylinder Block Grinding Machine" or "Part for Gear Grinding Machine". Include dimensions, weight, power supply, NC control details. |
| β Technical Drawings | βοΈ | Show whether it's an external or internal cylindrical grinder. Critical for distinguishing 8460.24.00.10 vs .30. |
| β Photos (with Nameplate) | βοΈ | Clear image of model number, brand, and any labels indicating "For Cylinder Blocks" or "For Gears". |
| β Commercial Invoice | βοΈ | Accurate description. Avoid vague terms like "Machine Part". Use exact HS Code if known. |
| β Packing List | βοΈ | Detail components. If parts are shipped separately, ensure they match the declared machine. |
| β Certifications | βοΈ | CE, UL, or other safety certifications if applicable. |
β 2. Declaration Tips (Key Mantra)
π₯ "Machine for Cylinders? Use 8460.24. Part for Gears? Use 8466.93. Don't Mix Them!"
| Scenario | Correct Declaration | Incorrect Practice |
|---|---|---|
| NC Cylinder Block Grinder (External) | 8460.24.00.10 |
Misdeclare as gear machine part β 0% or 29.7% error |
| NC Cylinder Block Grinder (Internal) | 8460.24.00.30 |
Misdeclare as general machine β Tax retrieval failure |
| Bed/Base for Gear Grinder | 8466.93.53.40 |
Declare as cylinder block part β Misclassification |
| Other Part for Gear Grinder | 8466.93.98.40 |
Declare as cylinder block part β 29.7% vs 0% risk |
β 3. Special Cases
| Case | Handling Advice |
|---|---|
| OEM Cylinder Block Machine | Provide customer order + design specs. Ensure description matches "Cylinder Block" not "Gear". |
| Machine for Gears (Misnamed as Cylinder Block) | If it's actually for gears, use 8466.93 codes. If it's for cylinders, do NOT use 8466.93. |
| Parts Shipped Separately | Ensure each part is correctly classified. Bed for cylinder machine β Bed for gear machine. |
| Tax Info Missing for Machines | Since 8460.24 tax info failed retrieval, consult a customs broker for current 2026 rates. Do not assume 0%. |
π V. Global Main Market Clearance Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff (Est.) | Certification | Notes |
|---|---|---|---|---|
| πΊπΈ USA | 8460.24.00.10 / .30 |
β Check Broker (Data Missing) | CE/UL | For parts (8466.93), see above. |
| π¨π³ China | 8460.24 |
~6-10% (General) | CCC (if applicable) | Base rate for grinding machines is typically low. |
| πͺπΊ EU | 8460.24 |
~0-4.5% | CE | No additional duties for machinery. |
| π―π΅ Japan | 8460.24 |
~0-3% | PSE | Low tariffs for precision machinery. |
π Conclusion:
- Machine Codes (8460.24): Tax data is missing in<DATA>. You MUST verify current rates.
- Part Codes (8466.93): Only for gear machines. Use8466.93.53.40(0%) or8466.93.98.40(29.7%).
- β οΈ Critical: Do not use gear-related HS codes for cylinder block machines unless the part is genuinely for gear grinding.
π VI. Common Errors & Pitfall Avoidance (Blood Lessons)
β Error 1: Declaring a Cylinder Block Grinder under 8466.93 (Gear Machine Parts)
π Consequence: Misclassification. If the part is not for gear machines, you may face fines or delayed clearance.
π Solution: Use 8460.24.00.10 or .30 for the machine.
β Error 2: Assuming 0% Tax for all Cylinder Block Grinders
π Consequence: Since tax info for 8460.24 is "Failed to retrieve", assuming 0% could lead to underpayment.
π Solution: Consult a customs broker for current rates.
β Error 3: Mixing up Internal and External Cylindrical Grinders
π Consequence: Wrong HS code (8460.24.00.10 vs .30).
π Solution: Check if the machine grinds the inner bore (Internal) or outer surface (External).
β Error 4: Using 8466.93.98.40 (29.7%) unnecessarily
π Consequence: Overpaying if the part qualifies for 8466.93.53.40 (0%).
π Solution: Ensure the part is a bed/base/casting (0%) vs. other accessory (29.7%).
β Correct Practice:
"CNC Cylinder Block Internal Grinder, Model XYZ, for Internal Cylindrical Grinding, CE Certified" β
8460.24.00.30
"Gear Grinder Bed Casting, Model ABC" β8466.93.53.40
π― VII. Conclusion: Professional Declaration, Save Time and Money!
π― Remember the Mantra:
πΉ "Cylinder Block? Use 8460.24. Gear Part? Use 8466.93. Don't Mix!"
πΉ "Tax Missing for Machines? Ask a Broker. Parts for Gears? 0% or 29.7%."
π Tips:
- For machines (8460.24), tax data is not available in <DATA>. Always verify with a customs broker.

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
