📌 One, Product Definition & Classification: What Exactly Is a "Ring Head Screw"?

A ring head screw is a type of threaded fastener with a circular, raised head that provides a larger bearing surface and improved grip, commonly used in woodworking, furniture assembly, cabinetry, and light industrial applications. The ring head design allows for easier driving and better resistance to stripping, especially in softer materials like wood.

⚠️ Key Classification Clue:
- If the screw has a ring-shaped head, threaded shank, and is made of copper or iron/steel, and used for wood → it falls under specific HS codes in Chapter 74 (Copper) or Chapter 73 (Iron/Steel).
- The diameter of the shank or thread is the critical factor for precise classification.

📦 Two, HS Code Classification Details (2026 Official Tariff Breakdown)

🔍 Critical Note:
- "Ring head" is not a standalone category — it’s subsumed under broader classifications based on material, diameter, and use. - Diameter < 6 mm vs ≥ 6 mm is the deciding factor for different HS codes. - Copper vs Iron/Steel determines whether it falls under Chapter 74 (Copper) or Chapter 73 (Iron/Steel).

💰 Three, 2026 Updated Tariff & Duty Breakdown (Including Additional Taxes)

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: November 10, 2025 (including subsequent imports)

🎯 1. 7415.33.05.00 — Copper Ring Head Screws for Wood (Diameter < 6 mm)

📌 Explanation:
- This code applies to copper screws with ring heads, used for wood, and with thread/shank diameter < 6 mm. - The 50% additional tariff is due to Section 301 tariffs on steel, aluminum, and copper products from China. - No base duty, but 50% extra — a very high effective rate.

🎯 2. 7415.33.80.50 — Other Copper Screws & Bolts (Diameter < 6 mm)

📌 Note:
- Applies to other copper threaded articles (not for wood), with diameter < 6 mm. - Same 50% additional tariff as above — no difference in rate, even if not for wood. - Must confirm use case — if used in wood, use 7415.33.05.00.

🎯 3. 7318.13.00.30 — Iron/Steel Screw Hooks & Rings (Diameter < 6 mm)

📌 Key Point:
- Applies to iron/steel ring head screws or hooks with diameter < 6 mm. - Even if used in non-wood applications, the 50% tariff applies due to steel material. - Not limited to wood — applies to all small iron/steel threaded fasteners.

🎯 4. 7318.13.00.60 — Iron/Steel Screw Hooks & Rings (Diameter ≥ 6 mm)

📌 Important:
- Same 50% tariff as the smaller version. - Diameter ≥ 6 mm is the only difference — no duty relief. - Do not assume larger size = lower tariff — the 50% add-on applies equally.

🌍 Five, Global Market Comparison (2026 Tariff Snapshot)

📌 Conclusion:
- The U.S. is the only major market with a 50% additional tariff on copper/iron/steel fasteners from China. - China-origin ring head screws are extremely expensive to import into the U.S. - Consider shifting origin to Vietnam, Mexico, or Thailand for tariff relief.

📌 Six, Common Mistakes & How to Avoid Them (Real-World Pitfalls)

❌ Mistake 1: Declaring all ring head screws as 7415.33.05.00 — even if not for wood
👉 Result: Misclassification → 50% tariff applied incorrectly → penalties

❌ Mistake 2: Not measuring thread/shank diameter — assuming all are <6 mm
👉 Result: Wrong HS code → 50% extra tax or delayed clearance

❌ Mistake 3: Combining copper and steel screws in one shipment
👉 Result: Split by material — cannot declare as one item → audit risk

❌ Mistake 4: Using "ring screw" as a generic name on invoice
👉 Result: Customs cannot verify size/material → delay or rejection

✅ Correct Declaration Example:

“Ring Head Screw, Copper, Thread Diameter: 4.5 mm, Used for Wood, HS Code: 7415.33.05.00, CIF: $1.20/unit, Origin: CN”

🎯 Seven, Final Verdict: Smart Import = Smart Savings

🎯 Remember the Golden Rule:

🔹 “Material + Size + Use = Correct HS Code”
🔹 “Size < 6 mm? Use 30.
🔹 “Size ≥ 6 mm? Use 60.”
🔹 “Copper? Use 7415.
🔹 “Steel? Use 7318.
🔹 “China origin? Expect 50% extra duty!”

📌 Pro Tip:

If your ring head screws are made in Vietnam, Mexico, or Thailand, you can apply for IEEPA exemption — tariff drops to 0%.
✅ Apply for Advance Ruling before shipment to lock in HS code and avoid surprises.
