Pyrazole Fungicide

🌿 Pyrazole Fungicide – Comprehensive HS Code & Tariff Guide (2026 Edition)

🌐 HS Code Classification & Customs Clearance Strategy | 2026 Updated Tariff Breakdown | Expert-Level Import Compliance
📌 One Product, Four Critical HS Codes – Know Exactly Where It Belongs!

Pyrazole fungicides are a class of advanced agricultural chemicals used to combat fungal diseases in crops. These compounds are highly effective due to their unique non-fused pyrazole ring structure or nitrogen-containing heterocyclic frameworks, making them essential in modern crop protection.

However, misclassification can lead to massive tariff overpayments, delays, or even seizure. Below is the definitive, data-driven guide based on real-time customs data, with full tax breakdowns, legal references, and actionable clearance strategies.

📦 1. HS Code Classification Breakdown (2026 Official Tariff Data)

⚠️ Critical Insight:
- Same active ingredient, different chemical structure → different HS codes → drastically different tariffs
- Do not assume all pyrazole fungicides are the same. Structure matters.

💰 2. 2026 Tariff Breakdown – Full Tax Clause Analysis (U.S. Import Focus)

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

🎯 1. 2933.19.23.00 – Non-Fused Pyrazole Ring, Pesticide Use

📌 Why This Rate Applies:
- The non-fused pyrazole ring is classified under 2933.19.23.00, which is subject to 301 + IEEPA tariffs due to its pesticide function and Chinese origin.

🎯 2. 2933.39.21.00 – Nitrogen-Containing Heterocycle, Fungicidal Use

📌 Why This Rate Is Lower:
- Although still subject to IEEPA 10%, this code does not trigger the 25% Section 301 tariff due to structural classification under 2933.39.21.00 (nitrogen heterocycle).

🎯 3. 3808.92.15.00 – Aromatic/Modified Aromatic Pyrazole Fungicide

📌 Why This Rate Applies:
- The aromatic structure places it under 3808.92.15.00, which is subject to both 301 and IEEPA tariffs.

🎯 4. 3808.92.50.80 – Fungicidal Agent, Non-IPBC Specific

📌 Why This Rate Applies:
- Non-IPBC classification means it avoids IPBC-specific restrictions, but still falls under 301 and IEEPA due to fungicidal function and origin.

🛠️ 3. Customs Clearance Best Practices (Pro Tips to Avoid Penalties)

✅ 1. Required Documentation (MUST Provide)

✅ 2.申报技巧（Key Rules of Thumb）

🔥 “Structure First, Function Second – Tax Depends on Ring Type!”

📌 Golden Rule:
Do not rely on product name alone. Structure determines HS code.

✅ 3. Special Cases & Risk Mitigation

🌍 4. Global Market Comparison (2026)

📌 Takeaway:
- U.S. is the only market with 40%+ tariffs on Chinese-origin pyrazole fungicides
- Vietnam/Mexico origin can reduce tariff to 0–5% – consider supply chain shift

📌 5. Common Mistakes & How to Avoid Them

❌ Mistake 1: Using “fungicide” as the only description
👉 Result: Customs may assume 2933.19.23.00 → 41.5% tax
✅ Fix: Include chemical structure in description:

"Pyrazole fungicide, non-fused ring, 98% purity, for agricultural use, HS: 2933.19.23.00"

❌ Mistake 2: Not providing structure diagram
👉 Result: Delayed clearance, possible reclassification
✅ Fix: Attach PDF of molecular structure with invoice

❌ Mistake 3: Assuming all pyrazole fungicides are the same
👉 Result: Pay 41.5% when only 16.5% applies
✅ Fix: Verify ring structure before申报

🎯 6. Final Verdict: Maximize Savings, Minimize Risk

🔹 Structure determines tax – not brand, not name, not function alone
🔹 2933.39.21.00 is your lowest-tax option (16.5%) if nitrogen heterocycle
🔹 3808.92.50.80 is best for non-IPBC formulations (40.0%)
🔹 Avoid 301/IEEPA tariffs by sourcing from Vietnam/Mexico/Thailand

📣 Action Now: Secure Your Shipment, Lock in Savings!

📞 Contact a U.S. Customs Broker + Submit Structure + Request Pre-Ruling
🚀 Avoid 41.5% overpayment – save thousands per shipment!

✨ Pro Tip:

If your fungicide is not from China, you may qualify for IEEPA exemption – apply for CO of Origin from Vietnam/Mexico.

📌 Remember:

"One wrong HS code = 25% more in tariffs. One correct structure = thousands saved."
