Thiourea Fungicide Emulsifiable Concentrate

🌿 Fungicide (Thiourea Fungicide Emulsifiable Concentrate)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition and Classification: What exactly is "Thiourea Fungicide"?

Thiourea Fungicide Emulsifiable Concentrate (EC) is a chemical pesticide formulation used primarily in agriculture to control fungal diseases on crops.

In international trade, its classification depends heavily on its chemical composition and primary function. While "Emulsifiable Concentrate" suggests a cleaning/detergent role, the active ingredient Thiourea and the declared purpose "Fungicide" place it firmly within the pesticide/chemical protection sector. However, depending on the specific formulation ratios and regulatory interpretation, customs authorities may view it differently.

⚠️ Key Distinction Point:
- If the product is primarily defined by its sulfur-containing chemical structure and fungicidal function → It falls under Chapter 38 (Insecticides, Rodenticides, Fungicides...).
- If the product is primarily viewed as a surface-active agent or wetting agent used in preparation → It might be misclassified or alternatively considered under Chapter 34 (Detergents/Cleaning Preparations), though this is less common for pure fungicides.

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

Based on the provided data, here are the three potential HS Codes for Thiourea Fungicide Emulsifiable Concentrate. Note that HS Code 3808.92.24.00 is the most technically accurate for a sulfur-based fungicide, while others represent alternative or misclassification risks.

🔍 Key Reminder:
- 3808.92.24.00 is the strongest candidate because Thiourea is a sulfur-based fungicide. The summary explicitly states: "Belongs to fungicides, and sulfur-containing chemical components are highly consistent with classification." - 3402.90.50.10 is risky. Although the summary says it "belongs to fungicides," placing it in Chapter 34 (Cleaning Preparations) is often a result of misunderstanding the "Emulsifiable Concentrate" (EC) formulation base (which uses surfactants). For import purposes, declaring it as a pesticide (Ch 38) is safer to avoid rejection for "misdeclaration of pesticide registration."

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

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

🎯 1. 3808.92.24.00 — Fungicide, Sulfur-Containing

📌 Explanation:
- The 25% USITC surtax is applied because fungicides from China are targeted under trade remedies. - The 10% IEEPA surtax is the additional levy for Chinese origin goods. - Total 35%: This is a high cost factor. Even with 0% base tariff, the surcharges dominate.

🎯 2. 3402.90.50.10 — Cleaning Preparations (Alternative/Misclassification)

📌 Warning:
- While the rate is significantly lower (13.7% vs 35%), declaring a Fungicide as a Cleaning Preparation is a major compliance risk. - The EPA (Environmental Protection Agency) regulates pesticides. Misdeclaring a pesticide as a detergent can lead to seizure, fines, and import bans. - The summary notes: "Product belongs to fungicides... consistent with chemical component usage in detergents." This is a descriptive match, not a regulatory endorsement. Do not use this code unless explicitly advised by customs brokers for a specific non-pesticide formulation.

🎯 3. 3808.92.28.00 — Other Fungicides (Sulfur Amides/Compounds)

📌 Note:
- This code is used if 3808.92.24.00 is not specific enough for the Thiourea structure. - It has the highest total rate (38.7%) due to the 3.7% base tariff + 25% + 10%. - Use this only if 24.00 is explicitly excluded by regulatory lists for Thiourea.

🌍 V. Global Market Comparison (2026 Latest)

📌 Conclusion:
- The USA market is the most expensive due to the 35% total tariff (Base 0% + 25% + 10%). - EPA compliance is non-negotiable. Without it, the product cannot be imported regardless of tariff. - Avoid 3402.90.50.10 despite the lower rate (13.7%). The regulatory risk of misdeclaring a pesticide as a detergent far outweighs the 21.3% savings.

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

❌ Error 1: Declaring "Thiourea Fungicide" as "Industrial Cleaner" (3402)
👉 Consequence: EPA intercepts shipment. Fines, seizure, and blacklisting.

❌ Error 2: Assuming "Emulsifiable Concentrate" means it’s a detergent
👉 Consequence: Customs rejects classification. Delay for re-classification + storage fees.

❌ Error 3: Ignoring the 10% IEEPA Surcharge
👉 Consequence: Underpayment of duties. Back taxes + interest upon audit.

❌ Error 4: Using 3808.92.28.00 without justification
👉 Consequence: Paying 38.7% instead of 35.0%. Unnecessary cost.

✅ Correct Practice:

"Thiourea Fungicide, Emulsifiable Concentrate, EPA Reg. No. [XXXXX], Active Ingredient: Thiourea [X]%, HS Code: 3808.92.24.00"

🎯 VII. Conclusion: Professional Declaration Saves Money and Ensures Compliance

🎯 Remember the Mantra:

🔹 "Pesticide is Pesticide. EPA is Mandatory. Chapter 38 is Correct. Don't Be Greedy with Codes!"
🔹 "35% is High, But 100% Seizure is Worse. Compliance First, Cost Second."

📌 Pro Tip:

• Apply for an Advance Ruling from CBP to lock in 3808.92.24.00.
