🚙 Wheel Nuts (车轮螺母)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Breakdown | Professional Compliance Strategy

Wheel Nuts (轮毂螺母) are critical fasteners that secure vehicle wheels to the hub. In international trade, classification is not a "one-size-fits-all" scenario. It heavily depends on the material composition (Aluminum vs. Steel/Iron) and the specific application. Misclassification can lead to massive duty spikes due to Section 301 and IEEPA tariffs.

Below is the precise breakdown based on the provided data, analyzing why each HS Code applies and the resulting tax implications.

📦 1. HS Code Classification Logic & Tax Analysis

🎯 Option A: Aluminum-Based Fasteners

If your wheel nuts are made of Aluminum or Aluminum Alloys.

HS Code: 7616.10.90.30

• Description: Nuts (fasteners), Aluminum-made.
• Why this code?: The summary states: "Nuts belong to fasteners, material inferred as aluminum or metal products, form matches threaded fasteners definition."
• Total Tax Rate: 41.0%
• Tax Breakdown:
  • Basic Duty: 6.0%
  • Section 301 Tariff: +25.0%
  • IEEPA Tariff (122 Clause): +10.0%
• Legal Basis: Aluminum fasteners fall under Chapter 76.

HS Code: 7616.10.70.30

• Description: Nuts (fasteners), Aluminum Alloy or Steel (conflicting/alternative aluminum classification).
• Why this code?: The summary states: "Nuts are fasteners, material inferred as aluminum alloy or steel, no conflict with aluminum fastener attributes."
• Total Tax Rate: 40.5%
• Tax Breakdown:
  • Basic Duty: 5.5%
  • Section 301 Tariff: +25.0%
  • IEEPA Tariff (122 Clause): +10.0%
• Insight: This is slightly cheaper (0.5%) than 90.30, likely due to a specific sub-category for alloys.

🎯 Option B: Steel/Iron-Based Fasteners (Standard Automotive)

If your wheel nuts are made of Steel, Iron, or Stainless Steel. This is the most common material for standard automotive lug nuts.

HS Code: 7318.16.00.30

• Description: Nuts, Washers, and Similar Products, of Iron or Steel (Threaded).
• Why this code?: The summary states: "Nuts, washers, and wheel nuts match the form completely, material usually iron or steel, meets material requirements."
• Total Tax Rate: 67.5%
• Tax Breakdown:
  • Basic Duty: 0.0%
  • Section 301 Tariff: +7.5% (Base 301 for steel fasteners is lower than aluminum in some contexts, BUT see Note 2 below)
  • IEEPA Tariff (122 Clause): +10.0%
  • 🚨 CRITICAL WARNING: The tax detail includes a note: "Steel, Aluminum, Copper products tariff: 50%".
  • Correction/Clarification: The data shows 67.5% as the result. If we look at the detail: 0.0% (Basic) + 7.5% (Addl) + 10% (IEEPA) = 17.5%. However, the data explicitly lists Total Tax: 67.5% and mentions a 50% surcharge for Steel/Aluminum/Copper.
  • Re-evaluation: It appears the 67.5% figure likely includes a massive 50% surcharge applied to the value or a specific high-tariff provision for "Steel/Aluminum/Copper" under the 122 clause or Section 232/301 overlap.
  • Actual Calculation based on Data: The data explicitly states 67.5% total. You must pay 67.5%. Do not attempt to calculate it as 17.5%.

HS Code: 7318.16.00.45

• Description: Wheel Nuts matching hub nuts form, Iron or Steel material.
• Why this code?: The summary states: "Matches wheel nut form and usage, material inferred as iron or steel, meets metal material requirements."
• Total Tax Rate: 67.5%
• Tax Breakdown:
  • Basic Duty: 0.0%
  • Section 301 Tariff: +7.5%
  • IEEPA Tariff (122 Clause): +10.0%
  • 🚨 CRITICAL WARNING: Same as above, includes the "Steel, Aluminum, Copper products tariff: 50%" note.
  • Total Tax Rate: 67.5% (As explicitly stated in the data).

🎯 Option C: Other Parts/Accessories

If the nuts are considered "Other parts and accessories" rather than generic fasteners.

HS Code: 8708.70.60.60

• Description: Parts and accessories of motor vehicles, specifically wheel hub assemblies or related parts.
• Why this code?: The summary states: "Vehicle wheel axle related parts/accessories, fits 'other parts' usage, material inferred as metal."
• Total Tax Rate: 37.5%
• Tax Breakdown:
  • Basic Duty: 2.5%
  • Section 301 Tariff: +25.0%
  • IEEPA Tariff (122 Clause): +10.0%
  • Total: 2.5% + 25.0% + 10.0% = 37.5%
• Insight: This is the LOWEST TAX RATE among all options if the product can be classified as a "vehicle part" rather than a generic "fastener."

🛠️ 3. Customs Clearance Strategic Advice

✅ 1. Priority Recommendation: Aim for 8708.70.60.60

• Why? At 37.5%, it is significantly cheaper than Steel Fasteners (67.5%) and slightly cheaper than Aluminum Fasteners (~40%).
• How to Achieve This?
  • Documentation: Clearly state in the commercial invoice and packing list that the item is a "Vehicle Wheel Hub Nut" or "Wheel Attachment Component" rather than just "Metal Nuts."
  • Technical Data: Provide a specification sheet showing that these nuts are specifically designed for vehicle wheel hubs (e.g., specific thread pitch, cone angle, load rating) and are not generic hardware store items.
  • HS Code Justification: Argue that they fall under Chapter 87 (Vehicles) as parts/accessories, specifically for securing the wheel to the axle/hub, rather than Chapter 73 (General Iron/Steel Articles).

⚠️ 2. Avoid Steel Classification (7318.16.00.x) if Possible

• Risk: The 67.5% rate includes a hidden 50% surcharge for "Steel, Aluminum, Copper products" mentioned in the tax detail. This is extremely punitive.
• Action: If you are using steel, try to justify if it can be treated as a "part" (Option A) or if there is any aluminum alloy variant available that fits the "7616" codes (~40.5%) which is still much cheaper than the steel route.

📄 3. Essential Documentation for Clearance

To support your HS Code choice, you must provide: * Commercial Invoice: Must clearly describe the item as "Wheel Nuts for Motor Vehicle" (not just "Nuts"). * Product Specification Sheet: Detail the material (Aluminum Alloy vs. Steel), dimensions, thread type, and intended vehicle application. * Material Test Report: If claiming Aluminum (7616), provide proof of aluminum composition to avoid being downgraded to Steel (7318). * Intended Use Statement: A letter stating these are parts for the automotive industry, supporting the Chapter 87 classification.

🌍 4. Global Market Note (US Focus)

• USA: The rates above are for US Imports from China.
  • IEEPA (122 Clause): The 10% surcharge is active for Chinese origin.
  • Section 301: The 25% or 7.5% depends on the chapter (73 vs 76 vs 87).
• Alternative Origins: If you can source these nuts from Vietnam, Thailand, or Mexico, you may be eligible for IEEPA exemptions or lower Section 301 rates.
  • Check: Verify if your supplier can provide a valid Certificate of Origin (COO) for a third country.

🎯 5. Conclusion & Final Tip

💡 Pro Tip: "Parts Over Hardware!" Always try to classify automotive-specific fasteners under Chapter 87 (8708.70.60.60) rather than Chapter 73/76 (Fasteners).

• Savings: Up to 27% tax difference between Steel Fasteners (67.5%) and Vehicle Parts (37.5%).
• Strategy: Emphasize the automotive application and specific design in your documentation to support the Chapter 87 classification.

✅ Action Plan: 1. Confirm Material: Is it Aluminum or Steel? 2. Draft Invoice: Use "Wheel Hub Nut for Motor Vehicle" as the description. 3. Apply HS Code: Start with 8708.70.60.60 (37.5%). If rejected, fallback to Aluminum 7616.10.70.30 (40.5%). 4. Avoid: 7318.16.00.45/.30 (67.5%) unless absolutely necessary.
