π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Full Analysis | Professional Clearance Strategy
π Part 1: Product Definition & Classification: Do You Really Understand "Agricultural Herbicide"?
Agricultural Herbicide, specifically in the form of Wettable Powder (WP), is a pesticide formulation designed to control unwanted plants in agricultural settings. The "Wettable Powder" form indicates that the active ingredient is mixed with inert carriers and adjuvants, requiring water suspension before application.
In international trade, the classification of herbicides depends heavily on their primary function, chemical composition, and whether they are classified as fertilizers or plant growth regulators.
β οΈ Critical Distinction:
- If the product is explicitly labeled and used as a Fertilizer or Plant Growth Regulator (promoting growth, not killing weeds), it may fall under Chapter 31 or Chapter 38 depending on the specific chemical nature.
- If the product is strictly a Herbicide (killing plants), it generally falls under Chapter 38 (Pesticides, Insecticides, etc.).
- Note: The provided data suggests two potential pathways: Fertilizer-related (Chapter 31) or Pesticide/Herbicide-related (Chapter 38). The choice depends on the dominant function declared and supported by technical data sheets.
π¦ Part 2: HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | Key Classification Feature |
|---|---|---|---|
3105.90.00.50 |
Plant Growth Regulators, Wettable Powder, classified under Fertilizer-related Chemicals | Products labeled as "Plant Growth Regulators" or "Fertilizer Additives" that promote growth | β Classified as Fertilizer-related |

Plant Growth Regulators, Wettable Powder, Powder Form Characteristic | Similar to above, focusing on the powder form and fertilizer/chemical category | β Classified as Fertilizer-related |
3808.93.50.40 |
Plant Growth Regulators/Herbicides, Wettable Powder, Hericidal/Anti-germination Traits | Products with herbicidal, anti-germination, or plant growth-regulating properties under pesticide chapter | β Classified as Pesticide/Herbicide |
3808.69.50.00 |
Preparations/Items under Pesticide Category, Wettable Powder | General Pesticide Preparations fitting theεΆε (formulation) form | β Classified as Pesticide/Herbicide |
π Key Reminder:
- Chapter 31 (3105.10/3105.90) applies if the product is primarily a fertilizer or plant growth regulator. - Chapter 38 (3808.93/3808.69) applies if the product is primarily a herbicide or pesticide. - Misclassification Risk: Declaring a herbicide as a fertilizer (or vice versa) can lead to severe penalties, duty underpayment, or customs seizure.

π Part 6: Common Mistakes & Pit-avoidance Guide (Lessons Learned)
β Mistake 1: Declaring a Herbicide as a Fertilizer to avoid higher duties
π Consequence: Customs audit reveals the true function β Penalties, Back Taxes, and Seizure.
β Mistake 2: Not providing EPA Registration Number for herbicides
π Consequence: Goods rejected at customs β Return or Destruction.
β Mistake 3: Using vague terms like "Plant Chemical" instead of "Wettable Powder Herbicide"
π Consequence: Customs classification delay β Storage Fees and Delays.
β Mistake 4: Ignoring Section 122 additional duty
π Consequence: Underpayment of 10% β Back Taxes and Interest.
β Correct Practice:
"Plant Growth Regulator, Wettable Powder, EPA Reg. No. XXXXX-XXX, For Promoting Plant Growth, Model XYZ, Made in China"
OR
"Herbicide, Wettable Powder, EPA Reg. No. XXXXX-XXX, For Weed Control, Model XYZ, Made in China"
π― Part 7: Conclusion: Precise Classification Saves Money!
π― Remember:
πΉ "Function Determines HS Code, HS Code Determines Duty."
πΉ "Fertilizer Path: 35% Total Duty."
πΉ "Herbicide Path: 40% Total Duty."

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
