Fluopyram Butyl Ester Herbicide

🌿 Herbicides: Fluopyram Butyl Ester & Agricultural Chemical Mixtures

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Entry Strategy
📌 Part 1: Product Definition & Classification – Do You Really Understand "Herbicides"?

Herbicides are essential agricultural inputs used to control unwanted vegetation. In international trade, they are strictly regulated under Chapter 38 of the HS Nomenclature. The term "Fluopyram Butyl Ester" refers to a specific active ingredient often formulated with other agents. However, based on the provided , the classification hinges not on the specific chemical name "Fluopyram," but on the type of active ingredient listed in the specific sub-headings.

The provided data specifically covers: 1. Mixtures of Glufosinate (2-amino-4-[hydroxy(methyl)phosphonoyl] butanoic acid) or its salts/esters. 2. Mixtures of Glyphosate (N-(phosphonomethyl) glycine) or its salts/esters.

⚠️ Critical Distinction:
- If your product contains Glufosinate (or its salts/esters) mixed with adjuvants → It falls under HS Code 3808.93.50.10.
- If your product contains Glyphosate (or its salts/esters) mixed with adjuvants → It falls under HS Code 3808.93.50.20.
- Note on Fluopyram: Fluopyram is typically classified as a fungicide or insecticide (often under 3808.91 or 3808.92). However, since the provided only includes Glufosinate and Glyphosate mixtures, and assuming the user's input "Fluopyram Butyl Ester Herbicide" might be a mislabeling or a mixture containing one of the listed active ingredients (as the prompt asks to explain why it classifies to the given HS codes), we must align with the explicit descriptions in the .

Assumption for this guide: The product is identified as a mixture containing either Glufosinate or Glyphosate (as per the available data), or it is a mixture where the active ingredient falls into these specific categories. If it strictly contains only Fluopyram (a pyridinone fungicide) without Glufosinate/Glyphosate, it would likely fall under a different HS code not provided in . However, adhering strictly to the constraint, we analyze the two available codes.

📦 Part 2: HS Code Classification Details (2026 Latest Tariff Authority Comparison)

🔍 Key Reminder:
- Both codes fall under 3808.93: "Herbicides, anti-sprouting products and plant-growth regulators".
- The distinction is strictly chemical: Glufosinate vs. Glyphosate.
- If the product is a "Butyl Ester" form, it must be verified if the butyl ester corresponds to Glufosinate or Glyphosate.
- Glufosinate Butyl Ester (often referred to as Phosphinothricin butyl ester) → 3808.93.50.10
- Glyphosate Butyl Ester (less common, usually Glyphosate Isopropylammonium salt) → 3808.93.50.20
- Adjuvants: The code specifically mentions "mixtures... and application adjuvants." Pure active ingredients might fall under different sub-headings (e.g., 3808.93.10), but preparations/mixtures fit the codes below.

💰 Part 3: 2026 Latest Tariff Rate Details (Base & Additional Duties)

✅ Applicable Country: China (CN) Import Tariff
✅ Origin: Generally Applicable (Most Favored Nation or General)
✅ Note on "Additional Duties": The shows 0.0% Additional Duty for these specific codes. This is crucial—it means no Section 301-style tariffs apply to these specific agricultural chemical mixtures in this context.

🎯 1. 3808.93.50.10 – Glufosinate Mixtures

📌 Explanation:
- This is a standard agricultural chemical tariff.
- The rate is relatively low (5%) compared to consumer electronics or textiles.
- No additional punitive tariffs are listed in the provided data for this specific code.

🎯 2. 3808.93.50.20 – Glyphosate Mixtures

📌 Explanation:
- Identical tax treatment to Glufosinate mixtures.
- Glyphosate-based herbicides are widely used, and the tariff structure is standardized.

🛠️ Part 4: Customs Clearance Practical Advice (Battle-Tested Pitfall Guide)

✅ 1. Documentation Checklist (Non-Negotiable)

✅ 2. Declaration Tips (Critical Mnemonic)

🔥 "Active Ingredient Determines Code: Glufosinate → .10, Glyphosate → .20. Adjuvants Included? Still 3808.93!"

✅ 3. Special Circumstances

🌍 Part 5: Global Market Comparison (2026 Latest)

📌 Conclusion:
- The 5% rate in the provided data is likely for China's import tariff.
- Global Variance: US and EU have different HS codes for herbicides (often split by active ingredient type, not just "herbicide").
- Compliance is Key: Agrochemicals are heavily regulated. Tariff is only 10% of the cost; licensing and safety compliance are 90%.

📌 Part 6: Common Errors & Pitfall Guide (Lessons Learned)

❌ Error 1: Assuming "Herbicide" automatically means 3808.93.50.10
👉 Consequence: Misclassification if it's Glyphosate (.20) or Fluopyram (likely 3808.91).
✅ Fix: Always check the Active Ingredient.

❌ Error 2: Ignoring "Adjuvants"
👉 Consequence: If declared as "Pure Active Ingredient," it might fall under 3808.93.10 (different rate). If it's a mixture, it must be 3808.93.50.xx.
✅ Fix: Clearly state "Preparation" or "Mixture" in the description.

❌ Error 3: Confusing "Butyl Ester" with a different chemical
👉 Consequence: If it's Fluopyram Butyl Ester (a fungicide), it does NOT fit 3808.93.50.10 or .20 (which are strictly Glufosinate and Glyphosate mixtures).
✅ Fix: Verify Chemical Structure. If it is Fluopyram, it is not in the provided . If the user insists it is one of the codes, they must be misidentifying the active ingredient, or the product is a mixture where Glufosinate/Glyphosate is the primary herbicide.

✅ Correct Declaration Example:

"Herbicidal Preparation containing Glufosinate Butyl Ester (10%) and Adjuvants, 5L Container, UN 2588" → 3808.93.50.10

🎯 Part 7: Conclusion: Precision in Agrochemicals Saves Money!

🎯 Remember the Mnemonic:

🔹 "Glufosinate → .10, Glyphosate → .20, Both 5% Base Rate!"
🔹 "Butyl Ester? Check the Acid Backbone. Adjuvants? It's a Mixture!"
🔹 "Fluopyram? Not in this Data! Check Chapter 38 Again!"

📌 Pro Tip:
If your product contains Fluopyram (a fungicide) and you are forced to use the provided codes, you must verify if it is a multi-purpose agrochemical containing Glufosinate/Glyphosate as a co-active ingredient. If it is purely Fluopyram, neither code applies, and you risk severe penalties for misdeclaration.

📣 Immediate Action:

📞 Confirm Active Ingredient: Is it Glufosinate or Glyphosate?
📄 Request SDS & Spec Sheet: From the manufacturer.
🚀 File Early: Agrochemicals require pre-approval in many jurisdictions.
