π± Quinclorac Plant Growth Regulator EC
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
π 1. Product Definition & Classification: What is "Quinclorac EC"?
Quinclorac is a selective systemic herbicide and plant growth regulator used primarily to control broadleaf weeds (like crabgrass and pigweed) in turf, cereals, and turfgrass. The "EC" stands for Emulsifiable Concentrate, a liquid formulation where the active ingredient is dissolved in an organic solvent with an emulsifier, allowing it to mix with water.
β οΈ Key Distinction for Classification:
- Is it a pure chemical substance? β Chapter 29 (Organic Chemicals)
- Is it a finished fertilizer? β Chapter 31 (Fertilizers)
- Is it a pest control/plant protection product (Herbicide)? β Chapter 38 (Pesticides/Herbicides)
π¦ 2. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
The following table maps the potential HS Codes based on the specific chemical nature and regulatory intent of Quinclorac EC.
| HS Code | Product Description | Applicable Scenario | Tax Rate (Total) |
|---|---|---|---|
2939.79.00.00 |
Plant Growth Regulators, not elsewhere specified | Quinclorac as a pure plant hormone/regulator derivative; basic chemical form | 10.0% |
3105.90.00.10 |
Fertilizers containing nitrogen, phosphorus, potassium | Misclassification risk: If labeled as nutrient supplement rather than herbicide | 35.0% |
3808.59.10.00 |
Pesticides, Herbicides, Fungicides (Other) | Most Likely: Quinclorac is primarily registered as a herbicide/weed killer; EC is a standard pesticide formulation | 16.5% |
3105.90.00.50 |
Other Fertilizers | Misclassification risk: If marketed as a soil conditioner with growth benefits | 35.0% |
π Critical Note:
-3808.59.10.00is generally the correct classification for Quinclorac EC when used as a herbicide, as it falls under "Pesticides" (Chapter 38).
-2939.79.00.00applies if the product is declared strictly as a "Plant Growth Regulator" chemical intermediate without pesticidal claims, but this is rarer for commercial EC formulations.
-3105.*codes are incorrect unless the product is explicitly a fertilizer, which Quinclorac is not (it kills plants, it doesn't feed them).
π° 3. 2026 Latest Tariff Rate Breakdown (Including Surcharges & Policy Add-ons)
β Applicable Country: United States (US)
β Origin: China (CN)
β Effective Date: November 10, 2025 (and subsequent imports)
π― 1. 3808.59.10.00 β Pesticides/Herbicides (Recommended)
| Item | Content |
|---|---|
| Base Tariff | 6.5% (ad valorem) |
| USITC Surcharge | 0% (No Section 301 additional duty for this specific subheading in some cases, but check latest lists; here listed as 0%) |
| IEEPA Surcharge | +10% (Targeting Chinese/HK products under IEEPA) |
| Total Rate | 16.5% |
| Tax Calculation | CIF Value Γ 16.5% |
| De Minimis Exemption | β Not Applicable |
| Legal Path | IEEPA:9903.01.25 β IEEPA:9903.01.24 β USITC:3808.59.10.00 |
π Explanation:
- The 10% IEEPA tariff is applied due to the product's origin from China.
- The 6.5% base tariff is the standard MFN rate for other pesticides.
- Total 16.5% is the most competitive among valid classifications.
- Note: Some interpretations may apply Section 301 duties, but based on the provided data,3808.59.10.00shows 0% USITC surcharge, resulting in the lowest valid tax.
π― 2. 2939.79.00.00 β Plant Growth Regulators (Alternative)
| Item | Content |
|---|---|
| Base Tariff | 0% |
| USITC Surcharge | 0% |
| IEEPA Surcharge | +10% |
| Total Rate | 10.0% |
| Tax Calculation | CIF Value Γ 10.0% |
| De Minimis Exemption | β Not Applicable |
| Legal Path | IEEPA:9903.01.25 β IEEPA:9903.01.24 β USITC:2939.79.00.00 |
π Explanation:
- If customs accepts the classification as a pure plant growth regulator (not a pesticide/herbicide), the base rate is 0%.
- The 10% IEEPA surcharge still applies due to Chinese origin.
- Total 10% is the lowest possible tax, but classification must be justified as a "growth regulator" rather than a "weed killer."
- Risk: High scrutiny if product label says "Kills Weeds."
π― 3. 3105.90.00.10 & 3105.90.00.50 β Fertilizers (High-Risk/Misclassification)
| Item | Content |
|---|---|
| Base Tariff | 0% |
| USITC Surcharge | +25% (Section 301) |
| IEEPA Surcharge | +10% |
| Total Rate | 35.0% |

| De Minimis Exemption | β Not Applicable |
| Legal Path | IEEPA:9901.25 β IEEPA:9903.01.24 β USITC:3105.90.00.10/50 β FOOTNOTE:9903.88.01 |
π Warning:
- DO NOT USE unless the product is genuinely a fertilizer.
- Quinclorac is toxic to weeds, not a nutrient. Misclassifying a herbicide as a fertilizer is fraudulent and leads to penalties, seizures, and back taxes.
- Total 35% is significantly higher than the herbicide classification.
π οΈ 4. Customs Clearance Practical Advice (Real-World Pitfall Guide)
β 1. Required Documentation Checklist
| Document | Mandatory? | Description |
|---|---|---|
| β Product Specification Sheet | βοΈ | Must state active ingredient (Quinclorac %), formulation (EC), and intended use (Herbicide vs. Regulator). |
| β Safety Data Sheet (SDS) | βοΈ | Required for chemical products. Shows hazard class and handling instructions. |
| β Label & Packaging Photos | βοΈ | Must match declared HS Code. If label says "Herbicide," you must declare as Pesticide (3808). |
| β Certificate of Analysis (COA) | βοΈ | Confirms purity and composition. |
| β Commercial Invoice | βοΈ | Clearly state "Quinclorac EC Plant Growth Regulator" or "Herbicide." |
| β EPA Registration Number (if US-bound) | βοΈ | If importing to the US, EPA registration is mandatory for pesticides. |
| β Origin Certificate | βοΈ | To apply IEEPA tariffs correctly. |
β 2. Declaration Tips (Key Mnemonics)
π₯ βLabel Defines, Use Classifies, EC is Liquid, Herbicide is Pesticide!β
| Scenario | Correct Declaration | Wrong Action |
|---|---|---|
| Product label says "Herbicide" | Declare as 3808.59.10.00 (Pesticide) |
Declare as Fertilizer β 35% Tax + Penalty |
| Product label says "Growth Regulator" | Declare as 2939.79.00.00 (Chemical) or 3808 if it kills weeds |
Under-declare value β Audit Risk |
| Liquid Formulation (EC) | Declare as Emulsifiable Concentrate | Declare as Solid Powder β Inspection Delay |
| Chinese Origin | Expect 10% IEEPA Surcharge | Ignore IEEPA β Seizure |
β 3. Special Handling Cases
| Case | Recommendation |
|---|---|
| EPA Registration | If importing to the US, ensure the product is EPA-registered. Unregistered pesticides will be detained and destroyed. |
| Dual-Use Products | If marketed as both "Fertilizer" and "Weed Killer," customs will classify as Pesticide (3808) due to its primary function. |
| Bulk vs. Retail | Bulk EC formulations may require additional safety packaging (UN-certified drums). |
| Pre-Ruling | Apply for an Advance Ruling from CBP to confirm whether 2939 or 3808 applies based on your specific product label. |

π 6. Common Errors & Pitfalls (Lessons Learned)
β Error 1: Classifying Quinclorac EC as a Fertilizer (3105)
π Consequence: 35% Tax + Customs Fraud Investigation + Product Destruction.
π Why: Quinclorac kills plants; it does not nourish them.
β Error 2: Ignoring EPA Registration when importing to the US
π Consequence: Detention at Port, Return to Sender, or Destruction.
π Why: All pesticides must be EPA-registered before import.
β Error 3: Using "Plant Growth Regulator" label but declaring as 2939 when the product kills weeds
π Consequence: Misclassification Penalty, Back Taxes, Interest.
π Why: If it has pesticidal activity, it falls under Chapter 38.
β Error 4: Not disclosing Chinese Origin for IEEPA Tariffs
π Consequence: 10% Underpayment + Penalties.
π Why: IEEPA tariffs are strictly enforced for Chinese-origin goods.
β Correct Approach:
"Quinclorac EC, Emulsifiable Concentrate, Herbicide, EPA Registration #XXXXX, Made in China"
π― 7. Conclusion: Professional Classification Saves Money!
π― Remember the Mantra:
πΉ "Herbicide = Pesticide (3808), Regulator = Chemical (2939), Fertilizer = 3105 (Wrong!)"
πΉ "EC means Liquid, Label Determines Truth, IEEPA 10% is a Must!"
πΉ "HS Code Life or Death, Tax Differs by 25%, Declaration Accuracy Pays!"
π Pro Tip:
If your product is primarily a weed killer, declare as
3808.59.10.00(16.5% Total).
If you can legally prove it is only a growth regulator with no pesticidal effect, declare as2939.79.00.00(10.0% Total).
Never declare as Fertilizer (3105) unless it is.

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) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β 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 β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
