🧭 Ring Head Screws & Fasteners (Iron & Steel)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Updated Tariff Analysis | Strategic Clearance Protocol
📌 Part 1: Product Definition & Classification – Do You Really Know "Ring Head Screws"?

Ring Head Screws (often referred to as "Round Head Screws" or "Hex/Washer Head Screws with ring/loop head features") are critical fastening elements in the automotive, machinery, construction, and marine industries. They are typically made of iron or steel and feature a rounded or domed head that may include a hole (eyelet) for lashing, securing, or decorative purposes.

In international trade, these fasteners are classified based on: - Material: Iron or steel (not stainless steel unless specified) - Form: Forged or stamped - Dimensions: Diameter of shank/thread (≥6mm or <6mm) - Type: With nuts, without nuts, with or without washers - Special Features: Round head, eyelet, hook-like design

⚠️ Key Classification Criteria:
- If made of iron/steel and has a round head, it falls under 7318.15 series;
- If made of stainless steel, it may fall under different subheadings (e.g., 7318.15.20.51);
- If the item is a screw with ring/eyelet head, it must be declared precisely to avoid misclassification penalties.

📦 Part 2: HS Code Breakdown (2026 Tariff Manual Alignment)

🔍 Critical Note:
- Ring head screws made of iron or steel with ≥6mm diameter must be declared under 7318.15 series;
- If made of stainless steel, they fall under 7318.15.20.51;
- If made of base metal (non-steel), they fall under 8308 series;
- Forged/stamped parts not further worked fall under 7326.19.00.

📌 Part 6: Common Mistakes & Avoidance Tips

❌ Mistake 1: Declaring "ring head screws" as "base metal"
👉 Result: 0% → 75% + penalty

❌ Mistake 2: Failing to specify material (stainless vs. iron)
👉 Result: Customs reclassification → 75%

❌ Mistake 3: Declaring "forged parts" as "finished screws"
👉 Result: 77.9% instead of 50%

❌ Mistake 4: Using generic terms like "screws" without details
👉 Result: Customs delay + possible seizure

✅ Correct Approach:

"Ring Head Screws, Round Head, 8mm, Stainless Steel 304, ASTM A193, with Matching Nuts, 1000 Units"

🎯 Part 7: Final Summary – Precise Declaration, Lower Cost, Faster Clearance

🎯 Remember the Golden Rules:

🔹 "Material First: Stainless = 25%, Iron = 75%"
🔹 "Diameter Matters: ≥6mm = Higher Duty"
🔹 "Forged vs. Finished: 50% vs. 77.9%"
🔹 "Base Metal ≠ Iron: 0% vs. 75%"

📌 Pro Tip:

If your ring head screws are originating from Vietnam, Mexico, Thailand, or Malaysia, you may qualify for IEEPA exemption, reducing tariffs to 0–5%;
