🌿 Plant Growth Regulators (Wettable Powder) – Complete HS Code & Tax Strategy 2026
🌐 HS Code Reference & Clearance Guide | 2026 Customs Tariff Breakdown | Professional Clearance Strategy
📌 I. Product Definition & Classification: What exactly are "Plant Growth Regulators (Wettable Powder)"?
Plant Growth Regulators (PGRs) are chemical substances (natural or synthetic) used to control or modify the physiological processes of plants, such as germination, rooting, flowering, fruiting, and sprout inhibition.
"Wettable Powder" (WP) is a specific formulation type where the active ingredients are finely ground and mixed with carriers and wetting agents. It is designed to be mixed with water to form a suspension before application (spraying).
⚠️ Critical Classification Logic: - Scenario A (Formulated Product): If the product is already mixed, packaged for retail sale, or put up as a "preparation" (like the WP described), it falls under Heading 3808 (Pesticides & similar preparations). - Scenario B (Raw Chemical): If the product is a pure chemical compound (e.g., a specific heterocyclic compound) used to make the PGR but not yet formulated, it falls under Chapter 29 (Organic Chemicals).
Most commercial "Plant Growth Regulators (Wettable Powder)" are classified under Heading 3808. However, if the product is a specific aromatic chemical listed in Chapter 29, it might be misclassified if not properly declared.
📦 II. HS Code Classification Details (2026 Latest Tariff Breakdown)
Based on the provided data, here are the four potential classifications and why they apply (or don't) to "Plant Growth Regulators (Wettable Powder)":
| HS Code | Product Description | Applicable Scenario | Tax Rate |
|---|---|---|---|
| 3808.93.15.00 | Herbicides, anti-sprouting products, and plant-growth regulators: Containing any aromatic or modified aromatic herbicide/agent. | ✅ High Probability. If the Wettable Powder contains an aromatic active ingredient (e.g., 2,4-D, Naphthaleneacetic acid derivatives) and is put up in retail form. | 0.0% (Base + Add-on) |
| 3808.93.50.40 | Herbicides, anti-sprouting products, and plant-growth regulators: Other: Other Other. | ⚠️ Medium Probability. If the product is a PGR but does NOT contain aromatic/modified aromatic compounds, or is not in retail packing. | 30.0% (Base 5% + Add-on 25%) |
| 2933.99.22.00 | Heterocyclic compounds: Aromatic/Modified aromatic: Pesticides: Other: Other. | 🔍 Rare for WP. Applies only if declaring the raw chemical itself (not the formulated powder), specifically a heterocyclic compound with nitrogen. | 0.0% (Base + Add-on) |
| 2933.39.27.00 | Heterocyclic compounds: Pyridine ring: Pesticides: Other: Other. | 🔍 Rare for WP. Applies only if declaring the raw chemical itself containing an unfused pyridine ring. | 0.0% (Base + Add-on) |
🔍 Key Distinction: - 3808 Series: For Formulated Products (Mixtures, WP, Granules, Liquids ready to spray). - 2933 Series: For Pure Chemicals (Raw Active Ingredients).
If you are importing "Plant Growth Regulators (Wettable Powder)" as a commercial product, it is almost certainly 3808.93.15.00 or 3808.93.50.40.
💰 III. 2026 Customs Tariff Rate Breakdown (Detailed Tax Clauses)
✅ Context: Based on the data provided, we assume a scenario involving US-China trade (given the "Add-on Tax" structure typical of Section 301).
🎯 1. HS Code
3808.93.15.00Description: Herbicides, anti-sprouting products, and plant-growth regulators: Containing any aromatic or modified aromatic herbicide, anti-sprouting agent or plant-growth regulator.
Item Content Base Tariff 0.0% (Ad Valorem) Add-on Tariff 0.0% Total Tax Rate 0.0% Tax Detail "基础关税: 0.0%, 加征关税: 0.0%" Legal Basis Specific exclusion for aromatic PGRs in this category. Status ✅ Duty-Free 📌 Interpretation: - This is the most favorable classification for aromatic PGRs. - If your Wettable Powder contains aromatic compounds (common in herbicides and some regulators like NAA), you pay ZERO tax. - Crucial: You must prove the aromatic nature of the active ingredient.
🎯 2. HS Code 3808.93.50.40
Description: Herbicides, anti-sprouting products, and plant-growth regulators: Other: Other: Other Other.
Item Content Base Tariff 5.0% Add-on Tariff 25.0% (Section 301 / "Additional Tariff") Total Tax Rate 30.0% Tax Detail "基础关税: 5.0%, 加征关税: 25.0%" Legal Basis Section 301 Tariffs on Chinese agricultural chemicals. Status ⚠️ High Duty 📌 Interpretation: - This applies if the product is non-aromatic or falls into the "catch-all" bucket. - 30% is a massive cost. For example, on a $10,000 shipment, you pay $3,000 in duties. - Risk: Many generic plant regulators fall here if the active ingredient is aliphatic or non-aromatic.
🎯 3. HS Codes 2933.99.22.00 & 2933.39.27.00
Description: Heterocyclic compounds (Nitrogen only) / Pyridine rings used as Pesticides.
Item Content Base Tariff 0.0% Add-on Tariff 0.0% Total Tax Rate 0.0% Status ✅ Duty-Free (for raw chemicals) 📌 Interpretation: - Warning: These codes are for Pure Chemicals. - If you ship a "Wettable Powder" (a mixture of chemical + inert carriers) under these codes, Customs will likely reject it as misclassification. - Strategy: Only use these if you are importing the Active Ingredient (AI) in its pure form to mix later domestically.
🛠️ IV. Clearance Practical Advice (Real-World Avoidance Guide)
✅ 1. Preparation Checklist (Must-Haves)
| Document | Requirement | Reason |
|---|---|---|
| Material Safety Data Sheet (MSDS) | ✔️ Mandatory | Must clearly list the Active Ingredient (AI) and confirm if it is "Aromatic" or "Heterocyclic". |
| Formula Declaration | ✔️ Mandatory | Must state the % of AI and the nature of the carrier. |
| Certificate of Analysis (COA) | ✔️ Mandatory | To prove purity and chemical structure (Aromatic vs. Non-Aromatic). |
| Retail Packing Photos | ✔️ Mandatory | To confirm if it is "put up for retail sale" (3808) or "bulk" (2933). |
| Chemical Structure Diagram | ✔️ Recommended | Visual proof of "Aromatic Ring" for 3808.93.15.00. |
✅ 2. Declaration Tips (Golden Rules)
🔥 Rule: "Aromatic = 0%, Non-Aromatic = 30%!"
| Scenario | Correct HS Code | Tax Rate | Mistake Consequence |
|---|---|---|---|
| Product contains Aromatic AI (e.g., 2,4-D, NAA) | 3808.93.15.00 | 0% | Misdeclaring as "Other" (3808.93.50.40) → Lose 30% savings. |
| Product contains Non-Aromatic AI (e.g., Aliphatic acids) | 3808.93.50.40 | 30% | Misdeclaring as "Aromatic" → Audited & Penalized. |
| Pure Chemical (Not Powder) | 2933.99.22.00 or 2933.39.27.00 | 0% | Declaring "Wettable Powder" under 2933 → Rejection/Return. |
| Retail Pack vs Bulk | 3808 vs 2933/3808 | Varies | "Put up for retail" is key for 3808. |
📌 Strategy: - Check the Active Ingredient: Is it an aromatic compound? (Look for benzene rings, naphthalene rings, etc.). - If YES: Declare 3808.93.15.00. - If NO: Accept the 30% tax on 3808.93.50.40 or find a raw chemical supplier who can ship pure 2933 codes (if allowed).
✅ 3. Special Scenarios
| Situation | Advice |
|---|---|
| "Wettable Powder" contains multiple ingredients | Check if ANY component is aromatic. If yes, the whole product qualifies for 3808.93.15.00 (0% tax). |
| Customs asks for "Aromatic" proof | Provide a chemical structure diagram from the manufacturer showing the benzene ring. |
| Product is "Plant Growth Regulator" but also "Herbicide" | The description says "Other: Herbicides...". If it's primarily a regulator, use the regulator subheading. If it's a herbicide, the same tax logic applies. |
| Origin: Non-China (e.g., Vietnam) | The "Add-on Tax" (25%) might be waived if origin is verified, but Base Tax (5%) usually remains. 3808.93.15.00 is still 0% regardless of origin in this dataset. |
🌍 V. Global Market Comparison (2026)
| Region | Recommended HS Code | Tax Rate (China Origin) | Key Requirement |
|---|---|---|---|
| 🇺🇸 USA | 3808.93.15.00 (Aromatic) | 0% | Must prove aromatic structure. |
| 🇺🇸 USA | 3808.93.50.40 (Non-Aromatic) | 30% | High cost for non-aromatics. |
| 🇪🇺 EU | 3808.93 | Varies | Requires EU Approval (Regulation (EC) No 1107/2009). |
| 🇨🇳 China | 3808.93 | Varies | Requires Pesticide Registration Certificate. |
📌 Conclusion: - USA has a massive tax gap (0% vs 30%) based purely on chemistry. - Do not guess. Get a chemist to confirm the aromatic status of the active ingredient.
📌 VI. Common Mistakes & Pitfalls (Blood-Test Lessons)
❌ Mistake 1: Declaring all "Plant Growth Regulators" as 3808.93.50.40 (30% tax). 👉 Result: Paying extra 30% on products that are actually aromatic (0% tax). Fix: Check the chemical structure.
❌ Mistake 2: Declaring "Wettable Powder" under 2933 (Raw Chemical). 👉 Result: Customs rejects the declaration because it's a "preparation", not a "compound". Fix: Use 3808.
❌ Mistake 3: Missing the "Retail Sale" condition for 3808. 👉 Result: If shipped in bulk bags (e.g., 25kg), it might not be "retail sale". However, 3808 still covers "preparations". The main risk is misclassifying the chemical nature.
✅ Correct Declaration Example:
"Plant Growth Regulator (Wettable Powder), Active Ingredient: Naphthaleneacetic Acid (Aromatic), 500g Packet, For Agricultural Use." HS Code:
3808.93.15.00→ Tax: 0%.
🎯 VII. Conclusion: Precision is Profit!
🎯 Remember the口诀 (Mnemonic):
🔹 "Aromatic? 0% (3808.93.15)" 🔹 "Non-Aromatic? 30% (3808.93.50)" 🔹 "Raw Powder? Check 2933" 🔹 "Wettable Powder = 3808!"
📌 Pro Tip: If you are importing Plant Growth Regulators, the difference between 0% and 30% is the difference between profit and loss. Action: 1. Demand the Chemical Structure from the supplier. 2. Verify if it contains an Aromatic Ring. 3. Apply for Pre-Ruling if unsure.

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) — Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) — More specific grouping within the chapter
- Subheading (6 digits) — Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) — Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate — The standard duty rate applied to WTO members
- General rate — Applied to countries without trade agreements
- Trade remedy duties — Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
