🛠️ Drill Bit (Drilling Tools for Rock or Soil Penetration)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Breakdown | Professional Import Strategy
📌 One, Product Definition & Classification: Do You Really Know What a Drill Bit Is?

A drill bit is a cutting tool used for boring holes into rock, soil, concrete, or metal — essential in mining, construction, oil & gas, and civil engineering. In international trade, drill bits are classified based on material, function, and structure, with key distinctions between metal-based and diamond-tipped variants.

⚠️ Critical Differentiation: - Metal drill bits (e.g., high-speed steel, carbide-tipped) → classified under 8207.19.60
- Diamond-tipped drill bits (for hard rock, core drilling) → classified under 6804.21.00
- Cutting/drilling tools with no specific material → may fall under 8466.10.01

📦 Two, HS Code Classification Details (2026 Latest Tariff Authority)

🔍 Key Insight:
- Diamond bits are not classified under metal drill codes — they are separately listed due to material uniqueness. - Metal drill bits with diamond tips may still be classified under 8207.19.60 if the main body is metal, even if the tip is diamond.

💰 Three, 2026 Latest Tariff Breakdown (With附加 Taxes & Legal Basis)

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

🎯 1. 8207.19.60.70 — Metal Drill Bit for Rock/Soil Drilling

📌 Explanation:
- The 25% USITC tariff comes from Section 301 of the U.S. Trade Act (China-specific trade remedy). - The 10% IEEPA tariff is under the International Emergency Economic Powers Act — applies to goods from China/Hong Kong. - Total: 37.9% — high but lower than diamond bits due to 2.9% base rate.

🎯 2. 8466.10.01.30 — Cutting or Drilling Tools (General Category)

📌 Note:
- This code is for general-purpose drilling tools with no material conflict. - Even if the bit is metal, if it’s not clearly for rock/soil, this code may apply. - Higher than 8207.19.60.70 due to 3.9% base rate.

🎯 3. 6804.21.00.90 — Diamond Drill Bit (General Use)

📌 Why 35%?
- 0% base duty — diamond is not subject to standard metal tariffs. - But still subject to 25% + 10% due to China origin. - Lowest total rate among all drill bit codes — ideal for diamond bits.

🎯 4. 6804.21.00.10 — Diamond Drill Bit (As Spare Part or Component)

📌 Important:
- This code applies when the diamond bit is declared as a spare part or component (e.g., replacement tip, core barrel part). - Same tax rate as 6804.21.00.90 — but must be supported by documentation (e.g., invoice stating “spare part”).

🎯 5. 8207.19.60.65 — Diamond Drill Bit with Diamond Working Part (Rotary Rock Drill)

📌 Why This Code?
- Applies when the diamond bit has a rotating design and is used for rock drilling. - Despite being diamond-tipped, it’s classified under metal drill bit code due to form and function. - Higher rate than 6804.21.00.90 due to 2.9% base duty.

🌍 Five, Global Customs Comparison (2026 Update)

📌 Conclusion:
- The U.S. is the only market with high附加 tariffs on drill bits. - Diamond bits are cheaper to import into the U.S. than metal ones due to 0% base duty.

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

❌ Mistake 1: Classifying a diamond bit as a metal drill bit (8207.19.60.70)
👉 Result: 37.9% instead of 35.0% → extra 2.9% tax → $10K+ loss per container

❌ Mistake 2: Declaring a spare diamond tip as 6804.21.00.90 instead of 6804.21.00.10
👉 Result: Customs may reject or delay — no "part" context

❌ Mistake 3: Using generic name like “Drill Bit” without specifying material or function
👉 Result: Customs may apply default code (8466.10.01.30) → 38.9% → worst-case scenario

✅ Correct Declaration Example:

“Diamond Core Drill Bit, 65mm Diameter, for Hard Rock Drilling, Synthetic Diamond Working Section, Model XYZ, Spare Part, CE Certified”

🎯 Seven, Final Verdict: Precision Matters, Cost Depends on Accuracy!

🎯 Remember the Mantra:

🔹 “Diamond? Use 6804.21.00.90 or 10.
🔹 Metal? Use 8207.19.60.70 or 65.
🔹 Rotary Rock Drill? 8207.19.60.65.
🔹 No material? 8466.10.01.30.
🔹 Always match name, material, function, and document!

📌 Pro Tip:

If your drill bits are originating from Vietnam, Mexico, Thailand, or Malaysia, you may qualify for IEEPA exemption — tariff drops to 0%–5%.
