🔩 Cast Iron or Steel Products (Iron & Steel Articles)

🌐 HS Code Reference & Clearance Guide | 2026 Latest Tariff Analysis | Professional Customs Strategy
📌 I. Product Definition & Classification: What Are "Cast Iron or Steel Products"?

"Cast Iron or Steel Products" refer to manufactured articles made primarily of Cast Iron (a hard, brittle form of iron with high carbon content) or Steel (an alloy of iron and carbon, often with other elements). In international trade, these are broadly categorized under Chapter 73 of the HS Code system.

The classification depends heavily on: 1. Manufacturing Process: Are they cast, forged, welded, or threaded? 2. Specific Function: Are they general structural parts, fasteners, or specific industrial components? 3. Material Specifics: Is it primarily cast iron or steel?

⚠️ Key Distinction:
- 7325: Specifically covers Cast Iron articles. If the product is cast and not specified elsewhere, it often falls here.
- 7326: Covers Other Steel Articles (not cast, not fasteners, not tubes/pipes). This is the "catch-all" for steel products.
- 7318: Covers Screw Bolts, Nuts, Washers, and Similar Articles. If the product is a fastener, this chapter takes precedence.

📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)

Based on the provided data, here are the six matched HS Codes for "Cast Iron or Steel Products," categorized by their specific nature and tax implications.

Category A: Cast Iron Articles (Chapter 7325)

Category B: General Steel Articles (Chapter 7326)

Category C: Fasteners & Hardware (Chapter 7318)

🔍 Critical Reminder:
- If the product is a screw, bolt, or nut, it MUST go to 7318, not 7325/7326.
- If the product is cast (molded), it generally goes to 7325 unless it is a fastener.
- If it is steel (rolled, forged, welded) and not a fastener/cast, it goes to 7326.

💰 III. 2026 Latest Tariff Rate Breakdown (Including Surcharges & Policy Add-ons)

✅ Applicable Country: USA (US)
✅ Origin: China (CN)
✅ Effective Date: Post-November 2025 (Based on current policy trends)

🎯 1. 7325.99.10.00 – Other Cast Iron Articles

📌 Explanation:
- Cast iron is often scrutinized under Section 232 (National Security).
- Total burden: 85%. This is extremely high. Consider redesigning material or sourcing from non-China origins if possible.

🎯 2. 7326.90.86.88 – Other Steel Articles

📌 Note:
- Steel articles face the full brunt of Section 232 (50%) and Section 301 (25%).
- Total burden: 87.9%. The highest category among the options.

🎯 3. 7326.19.00.80 – Other Steel Articles

📌 Note:
- Same as above. Steel classification triggers heavy penalties.

🎯 4. 7318.19.00.00 – Other Screws, Bolts, etc. (Steel/Iron)

📌 Critical:
- Fasteners have a higher base duty (5.7% vs 2.9% or 0%).
- Total burden: 90.7%. This is the HIGHEST tariff among all listed codes.
- Advice: If possible, avoid classifying as "fasteners" if they can be argued as "general steel articles," but be honest in classification. Misclassification leads to severe penalties.

🎯 5. 7318.29.00.00 – Other Nuts (Steel/Iron)

📌 Note:
- Nuts have a slightly lower base duty (2.8%) than screws (5.7%).
- Total burden: 87.8%. Still extremely high.

🎯 6. 7325.99.50.00 – Other Cast Iron Articles

🌍 V. Global Market Comparison (2026 Latest)

📌 Conclusion:
- USA is the most difficult market for Cast Iron/Steel products from China due to layered tariffs (232 + 301 + 122).
- EU, UK, Japan, and Canada are significantly more favorable.
- Strategy: Consider transshipment (risky, illegal if not properly documented) or supply chain diversification (manufacture in Vietnam/Mexico) to avoid US surcharges.

📌 VI. Common Mistakes & Pitfalls (Lessons Learned)

❌ Mistake 1: Classifying Fasteners as General Steel Articles.
👉 Consequence: HS Code error. Fasteners have specific chapters. If misclassified, you may face penalties for undeclared goods.

❌ Mistake 2: Claiming Stainless Steel but shipping Plain Steel.
👉 Consequence: Fraud detection. Stainless steel often has lower base duties. Customs will inspect and penalize.

❌ Mistake 3: Ignoring Section 232.
👉 Consequence: Missing the 50% surcharge. Total cost calculation is wrong → Profit margin erosion.

❌ Mistake 4: Not declaring Section 122 (10%).
👉 Consequence: Underpayment of duties → Customs audit and back taxes + interest.

✅ Correct Approach:

"Cast Iron Pipe Fitting, ASTM A48, 2-inch, Black Finish, Model XYZ, Made in China"
HS Code: 7325.99.10.00
Total Duty: 85%

🎯 VII. Conclusion: Professional Classification, Cost Control, Efficiency!

🎯 Remember the Mantra:

🔹 "Fasteners go to 7318, Cast Iron to 7325, Other Steel to 7326."
🔹 "US Tariffs are High (85%+), Plan Ahead or Diversify."
🔹 "Stainless Steel is Different, Don't Mix Them Up!"

📌 Tips:
- If your product is from Vietnam, Mexico, or India, you may avoid Section 301 and Section 232 tariffs, reducing the rate to 0% - 5% base duty.
- Always apply for an Advance Ruling if the classification is ambiguous.
- Consult a Customs Broker to verify the "Section 232" applicability for your specific item type.
