📌 I. Product Definition & Classification: What Exactly is "Wettable Powder Sulfur Fungicide"?

Wettable Powder Sulfur Fungicide is a widely used agricultural chemical in powder form, mainly used for plant disease control. In international trade, due to different chemical structures and declared purposes, it may be classified into different HS codes, which leads to significant differences in tariff rates.

Key Distinctions: - Organic Sulfur Compound (Thiourea/硫脲): If the product is chemically identified as an organic sulfur compound (e.g., thiourea derivatives), it may fall under Chapter 29. - Pesticide Formulation (Fungicide Preparation): If it is a formulated product containing sulfur or sulfur-containing compounds as an active ingredient, it may fall under Chapter 38.

⚠️ Critical Classification Point: - If the main component is organic sulfur compound (such as thiourea) → May be classified under 2930.90.10.00 or 2930.90.30.00 - If it is a preparation containing sulfur compound as fungicide → May be classified under 3808.92.24.00 or 3808.92.28.00 - If it is carbonaceous adsorbent-related material (less likely for fungicide, but mentioned in data) → 3802.90.50.00

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

🔍 Key Reminder: - If the product is a formulated pesticide (preparation), it is more likely to be classified under Chapter 38 (3808). - If the product is a pure chemical substance (organic sulfur compound), it may be classified under Chapter 29 (2930). - 3808.92.24.00 offers the lowest total tax rate (35.0%), making it the most favorable for importers.
