🌿 Chlorothalonil Emulsifiable Concentrate (E.C.)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Pesticide Clearance Strategy
📌 I. Product Definition & Classification: What Exactly is "Chlorothalonil EC"?

Chlorothalonil is a broad-spectrum, non-systemic fungicide widely used in agriculture to control leaf spot, blight, and rust on a variety of crops. It is one of the most commonly used fungicides globally due to its effectiveness and relatively low mammalian toxicity.

Emulsifiable Concentrate (E.C.) refers to the physical form of the formulation. It is a liquid formulation containing Chlorothalonil active ingredient dissolved in an organic solvent, along with emulsifiers that allow it to mix with water to form an emulsion upon application.

⚠️ Key Distinction:
- Active Ingredient vs. Formulation: While the active ingredient is Chlorothalonil, the commodity being imported is the formulation (the mixture). Therefore, it must be classified under pesticide formulations, not just the chemical. - Liquid State: Being a liquid (E.C.), it is not classified as a powder or solid pesticide.

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

🔍 Key Reminder:
- Chlorothalonil is a FUNGICIDE. Do NOT classify it under Insecticides (3808.30) or Herbicides (3808.30 or 3808.30). - If the product is pure technical grade Chlorothalonil (≥95% purity, no formulation), it may fall under 2903.39.90, but 99% of commercial shipments are formulations, which fall under 3808.93.10. - Emulsifiable Concentrate (E.C.) is explicitly a pesticide formulation, making 3808.93.10 the most accurate classification for the finished product.

💰 III. 2026 Latest Tariff Rate Details (Including Surtaxes & Policy Add-ons)

✅ Applicable Country: United States (US)
✅ Country of Origin: China (CN)
✅ Effective Time: November 10, 2025 onwards (for subsequent imports)

🎯 1. 3808.93.10.00 —— Fungicides: Chlorothalonil Formulations

📌 Explanation:
- The 25% USITC surcharge comes from Section 301 of the U.S. Trade Act. - The 10% IEEPA surcharge is the additional tariff on Chinese goods under the International Emergency Economic Powers Act. - Total 35%: This is a high tariff for agricultural chemicals. Must be anticipated in cost calculations!

🎯 2. Why Not 2903.39.90.00 (Pure Chemical)?

If you mistakenly declare pure Chlorothalonil technical powder as 3808.93.10, or vice versa, it may lead to misclassification penalties. However, if you are importing pure Chlorothalonil technical material (not formulated for direct use), the classification changes:

📌 Note:
- Even if classified as pure chemical, the 35% total tariff remains high for Chinese-origin goods. - Formulated products (E.C.) are more common and must use 3808.93.10.

🌍 V. Global Market Customs Comparison (2026 Latest)

📌 Conclusion:
- USA is the most critical market due to high tariffs (35%) and strict EPA requirements. - EU has complex regulations: While tariff may be low, Chlorothalonil faces restrictions or bans in several EU member states. Verify local legality. - Always prioritize regulatory compliance (EPA/APVMA/etc.) over tariff optimization.

📌 VI. Common Mistakes & Pitfall Guide (Blood & Tears Lessons)

❌ Mistake 1: Declaring Chlorothalonil EC as Insecticide
👉 Consequence: Wrong HS Code → Seizure + Penalty. Chlorothalonil is a Fungicide.

❌ Mistake 2: Importing without EPA Registration
👉 Consequence: Complete Rejection. US Customs will not clear pesticide products without valid EPA Reg Number.

❌ Mistake 3: Ignoring Hazardous Material Classification
👉 Consequence: Chlorothalonil E.C. contains organic solvents. Must comply with DOT/IMDG dangerous goods regulations. Lack of proper labeling → Shipping Refusal.

❌ Mistake 4: Using “Chemical” instead of “Pesticide” in Description
👉 Consequence: Ambiguity → Customs Audit Delay. Be specific: “Chlorothalonil 75% Emulsifiable Concentrate, Fungicide”.

✅ Correct Practice:

“Chlorothalonil 75% EC Fungicide, EPA Reg No. XXXXX-XX, Hazardous Material Class 3, UN1263, Packed in 20L Drums”

🎯 VII. Conclusion: Professional Clearance, Save Time & Cost!

🎯 Remember the Mnemonic:

🔹 “Fungicide Not Insecticide, EPA Reg is Life, EC Is Liquid, Tariff 35% Hit!”
🔹 “HS Code Decides Fate, Tariff Difference 35 Points, Declaration Step Wrong, Fine Thousands!”

📌 Tips:
- If your Chlorothalonil EC is originated from Vietnam, India, or Brazil, you may avoid the 10% IEEPA surcharge, reducing the total tariff to 25%. - Recommend applying for an Advance Ruling with CBP to confirm the correct HS Code and ensure EPA compliance before shipping.
