π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Clearance Strategy
π I. Product Definition & Classification: What Exactly Are "Graved Parts"?
"Graved Parts" is not a standard international trade term. In the context of imports/exports, it is almost certainly a typo or colloquialism for:
- Spare Parts (ε€δ»Ά): Replacement components for machinery, vehicles, or electronics.
- Grave Parts (ε’θ¬η¨ε): Rare, but possible if referring to cemetery supplies (unlikely in general trade).
- Garbed Parts (ε θ¦ι¨δ»Ά): Parts with external covering (rare).
β οΈ Critical Assumption for This Analysis:
We assume "Graved Parts" = Spare Parts/Replacement Components for industrial machinery, vehicles, or electronic devices.
HS Code classification depends entirely on WHAT the part is for. There is no single HS code for "spare parts."
π¦ II. HS Code Classification Matrix (2026 Latest Tariff Authority)
| HS Code | Product Description | Applicable Scenario | Key Classification Rule |
|---|---|---|---|
8409.91 |
Parts suitable for use solely or principally with internal combustion pistons engines | Engine spare parts (e.g., pistons, valves) | Must be specific to engine type |
8431.20 |
Parts suitable for use solely or principally with machines of heading 8425, 8426, 8427 | Crane, lifting, handling equipment parts | Specific to lifting machinery |
8473.30 |
Parts and accessories suitable for use solely or principally with machines of heading 8471 (Automatic Data Processing Machines) | Computer/server spare parts (e.g., hard drives, motherboards) | Must be exclusive to ADPM |
8483.90 |
Parts of transmission shafts, bearings, gears, etc. | Mechanical transmission components | Generic mechanical parts |
8504.90 |
Parts of electrical transformers, converters, inductors | Electrical power component parts | Electrical specific |
8529.90 |
Parts suitable for use solely or principally with apparatus of heading 8525-8528 | TV/Monitor/Camera parts | Electronic display parts |
8714.90 |
Parts and accessories of motorcycles, bicycles, etc. | Vehicle spare parts | Must be specific to vehicle type |
π Key Classification Rule:
- "Spare Parts" are classified according to the FUNCTION of the PART, not the fact that they are "spares."
- If a part is specifically designed for one machine, it falls under that machineβs chapter.
- If a part is general purpose (e.g., standard bolts, screws), it may fall under Chapter 73 (Iron/Steel Articles) or 74 (Copper).
- Never classify spare parts as "Other" (e.g., 9900) without justification.

π οΈ IV. Customs Clearance Practical Advice (Combat Pitfalls)
β 1. Required Documentation Checklist (Non-Negotiable)
| Document | Required | Description |
|---|---|---|
| β Detailed Part Description | βοΈ | Must include: Name, Model, Function, Material, Origin. Avoid generic "Spare Parts." |
| β Technical Drawing/Schematic | βοΈ | Proves the part is specific to a certain machine. |
| β Product Photos | βοΈ | Clear images of the part, including labels/serial numbers. |
| β Commercial Invoice | βοΈ | Must state "Spare Part for [Machine Name], Model XYZ." |
| β Original Equipment Manufacturer (OEM) Letter | βοΈ | If applicable, confirm the part is genuine OEM. |
| β HS Code Pre-Ruling Request | βοΈ | Recommended for high-value parts to avoid classification disputes. |
β 2. Declaration Tips (Critical Keywords)
π₯ "Be Specific, Not Generic! Vague Descriptions = Higher Duty!"
| Scenario | Correct Declaration | Incorrect Practice |
|---|---|---|
| Electronics Spare Part | "Motherboard for Dell Server, Model XYZ, HS 8473.30" | "Computer Parts" β Risk of 89.5% classification |
| Engine Part | "Piston Ring for Cummins Engine, Material Steel" | "Mechanical Spare Part" β Risk of Chapter 73 classification |
| Vehicle Part | "Brake Pad for Toyota Camry, 2020 Model" | "Car Parts" β High risk of misclassification |
| General Fastener | "Steel Hex Bolts, M10, Length 20mm, HS 7318.15" | "Hardware Parts" β May be classified as "Other Iron Articles" |
β 3. Special Cases Handling
| Scenario | Handling Advice |
|---|---|
| OEM Replacement Parts | Provide OEM invoice and compatibility list. May qualify for lower duty if proven essential. |
| Aftermarket Parts | Must clearly state "Aftermarket" and provide technical specs. Risk of anti-dumping duties if applicable. |
| Used Spare Parts | May require additional inspections (e.g., EPA, FDA). Ensure compliance with environmental standards. |
| Parts Shipped Separately | If shipped separately from the main machine, declare as "Spare Parts" with correct HS code. Do not bundle with main machine unless intended as a kit. |
π V. Global Market Comparison (2026 Latest)
| Country/Region | Recommended HS Code Strategy | Tariff Impact | Certification Requirement | Notes |
|---|---|---|---|---|
| πΊπΈ USA | Chapter 84/85 Specific Subheadings | High (17-42%) | FCC, UL, EPA (if applicable) | Section 301 + IEEPA apply. Strict on "Spare Part" definition. |
| π¨π³ China | Chapter 84/85 Specific Subheadings | Low (0-5%) | CCC (if applicable) | No surcharges. Easier clearance. |
| πͺπΊ EU | Chapter 84/85 Specific Subheadings | 0-4.5% | CE, RoHS | No surcharges. VAT applies separately. |
| π¦πΊ Australia | Chapter 84/85 Specific Subheadings | 5-5% | RCM | No surcharges. |
| π―π΅ Japan | Chapter 84/85 Specific Subheadings | 0-3.5% | PSE | No surcharges. |
π Conclusion:
- USA is the most challenging market for "graved parts" (spare parts) due to Section 301 + IEEPA surcharges.
- EU/Asia offer much more favorable tariff environments.
- Strategy: Consider sourcing parts from non-China origins (e.g., Vietnam, Mexico) to mitigate US tariffs.
π VI. Common Mistakes & Pitfalls (Lessons Learned)
β Mistake 1: Declaring all parts as "Spare Parts" under a generic HS code.
π Consequence: Customs may assign a higher duty rate (e.g., 89.5% for "Other") or demand additional documentation.
β Mistake 2: Failing to specify the machine model the part is for.
π Consequence: Cannot prove the part is "specific" to a machine β Classified as general goods β Higher duty.
β Mistake 3: Ignoring Section 301 applicability.
π Consequence: Surprise 25% tax at customs β Cost overruns.
β Mistake 4: Using "Graved Parts" as a declaration term.
π Consequence: Customs rejection due to unclear description. Always use standard trade terms (e.g., "Spare Part," "Replacement Component").
β Correct Approach:
"Replacement Piston Ring for Cummins QSB 6.7 Engine, Material: Chrome Steel, HS 8409.91, Origin: China"
π― VII. Conclusion: Precision Classification Saves Money!
π― Remember the Mantra:
πΉ "Spare Parts are NOT Generic! Specific Function = Specific HS Code!"
πΉ "USA Tariff Trap: Section 301 + IEEPA = Up to 42% Duty!"
πΉ "Vague Description = High Risk!"
π Pro Tip:
If your parts are sourced from Vietnam, Mexico, Thailand, you may qualify for IEEPA Exemption (0-5% duty).
Consider Advanced Customs Ruling (ACR) for high-volume spare parts to lock in favorable classification.

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
