🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional通关 Strategy
📌 1. Product Definition and Classification: Do You Really Understand "Herbicides"?

Isoproturon Wettable Powder is a widely used selective herbicide in international trade, primarily employed for pre-emergence or post-emergence control of broadleaf weeds and some grasses in cereal crops. In the context of customs classification, it falls under the broad category of agricultural chemicals.

Key Classification Logic: * Category: Herbicides, anti-sprouting products, and plant-growth regulators. * Form: Wettable Powder (WP) – a solid formulation intended for dilution with water before application. * Specific Attribute: The product contains Isoproturon, which is chemically classified as an aromatic herbicide (specifically, a urea derivative with aromatic rings).

⚠️ Critical Distinction:
- If the product contains any aromatic or modified aromatic herbicide/anti-sprouting agent, it must be classified under subheading 3808.93.
- If it were a non-aromatic herbicide, it would fall under 3808.92 (Fungicides) or 3808.94 (Insecticides), but Isoproturon is aromatic, so it cannot be classified as a generic "other" herbicide under 3808.92.

📦 2. HS Code Classification Details (2026 Latest Tariff Alignment)

🔍 Important Note:
- Isoproturon is chemically 3-(4-isopropylphenyl)-1,1-dimethylurea, which contains an aromatic phenyl ring. Therefore, it strictly falls under 3808.93.15.00.
- Do NOT classify it under 3808.92.50.80 (Fungicides) or other "Other" categories unless it is explicitly a fungicide without aromatic herbicide properties. Misclassification can lead to significant tax discrepancies.
