📌 One Product, Three Possible HS Codes — Know Which One Applies to You!

📦 1. Product Definition & Classification: What Exactly Is an "Eccentric Wheel"?

An eccentric wheel is a mechanical component used in fastening systems — typically as a cam-type adjuster that allows for fine-tuning of tension or alignment in doors, panels, hinges, or industrial fixtures. It's commonly found in furniture, automotive, machinery, and construction applications.

⚠️ Key Insight:
- It is not a fastener itself, but a component used with bolts/screws to create adjustable or locking mechanisms.
- It is not a complete lock, nor a standalone screw — it's a metal part used in assembly.

🔍 Critical Question:
Is it threaded? If yes → likely 7318.19.00.00
If no → likely 7318.29.00.00
If it’s part of a lock mechanism → 8301.30.00.90

📊 2. HS Code Classification Breakdown (2026 Updated Tariff Table)

📌 Why So Many Codes?
Because the same physical part can be classified differently based on function, structure, and whether it has threads — and each has a drastically different tariff.

💰 3. 2026 Latest Tariff & Duty Breakdown (US Market | China Origin)

✅ Target Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: November 10, 2025 (including all new tariffs)

🎯 1. 8301.30.00.90 — Metal Lock Fittings (Zero-Thread or Threaded, but Part of Lock System)

📌 Explanation:
- This code applies only if the eccentric wheel is part of a lock system (e.g., used in door locks, security hinges, or cam-lock assemblies).
- Even if it’s not a full lock, if it’s designed and sold as a lock component, this tariff applies.
- Lowest tax rate among the three — only 23.2% — so this is the most favorable classification.

🎯 2. 7318.19.00.00 — Threaded Fasteners (e.g., Screws, Bolts, Threaded Eccentric Wheels)

📌 Explanation:
- Applies only if the eccentric wheel has threads (e.g., threaded shaft, internal thread for bolt).
- The 50% surcharge on steel/aluminum/copper products is automatic for Chinese-origin goods under Section 122.
- This is the highest tariff — over 90% — a major red flag for importers.

🎯 3. 7318.29.00.00 — Non-Threaded Fastener Parts (Cams, Washers, Spacers, Non-Threaded Eccentric Wheels)

📌 Explanation:
- Applies if the eccentric wheel has NO threads — purely a cam-shaped adjustment piece.
- Still triggers all three surcharges, including the 50% steel product tax.
- Slightly lower than 7318.19.00.00, but still over 87% — extremely high.

🔥 "Thread or No Thread? That’s the Tax War!"

📌 Golden Rule:

If it’s used in a lock → 8301.30.00.90
If it’s not part of a lock → use thread status to decide between 7318.19 or 7318.29

🌍 5. Global Market Comparison (2026)

📌 Insight:
- The US is the only market with 301/IEEPA/122 surcharges.
- China, EU, Japan, Australia are much safer for importers.

📌 6. Common Mistakes & Costly Errors

❌ Mistake 1: Assuming "eccentric wheel" = "lock part" → using 8301.30.00.90 without proof
👉 Risk: Customs may reject → reclassification → 90.7% tax

❌ Mistake 2: Not checking for threads → using 7318.29.00.00 for a threaded part
👉 Risk: Underpaid duty → penalties + interest

❌ Mistake 3: Splitting shipment into "parts" to avoid high tariffs
👉 Risk: Each part taxed at 87.8% or 90.7% → total tax over 200%

❌ Mistake 4: Using generic name like “adjustment wheel” or “cam”
👉 Risk: Customs can’t verify function → delayed clearance

✅ Correct Declaration Example:

“Eccentric Wheel, Non-Threaded, for Door Hinge Adjustment, Made of Steel, Part of Locking System, Model XYZ, Used in Furniture & Security Doors”

🎯 7. Final Verdict: How to Win the Tariff Game

🔥 Pro Strategy:

"If it’s used in a lock — claim 8301.30.00.90 — it’s your best friend!"

🎯 Key Takeaway:
- Thread status and functional use determine the entire tax outcome.
- Misclassification = 90%+ tax → can destroy your profit margin.
- Always provide proof: photos, drawings, usage context.
