π Thiazolone-Based Aromatic Insecticides & Plant Protection Products
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategy
π I. Product Definition & Classification: Understanding Thiazolone Insecticides
Thiazolone-based products belong to a specific chemical class of aromatic or modified aromatic insecticides. In international trade, these are typically formulated as preparations or articles (e.g., granules, emulsifiable concentrates, wands, or ready-to-use sprays) put up for retail sale or professional use.
Key characteristics: * Active Ingredient: Contains N-[[[(4-chlorophenyl)amino]-carbonyl]-2,6-difluorobenzamide] or similar thiazolone-derived aromatic compounds. * Formulation: Sold as mixtures with inert substances (carriers, solvents, stabilizers). * Regulatory Status: Subject to strict customs classification due to the presence of "aromatic" chemical structures, which triggers specific tariff lines under Chapter 38.
β οΈ Critical Distinction:
- If the product is a pure active ingredient (chemical compound alone) β It may fall under 2933 (Chemicals).
- If the product is a formulation/mixture (e.g., sold in bottles, bags, or as treated materials) β It falls under 3808 (Insecticides, fungicides, etc.).
- Most retail/professional insecticides are formulations, thus falling under HS Code 3808.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority)
Based on the provided data, there are two primary HS Codes for thiazolone-based aromatic insecticides, differentiated by whether the active ingredient is a specific named mixture or a general aromatic insecticide.

|---|---|---|---|
3808.91.15.00 |
Specific Mixture: Containing N-[[[(4-chlorophenyl)amino]-carbonyl]-2,6-difluorobenzamide mixed with inert substances | β
Exact Match Required: The product must contain this specific thiazolone derivative. β Form: Retail packing or preparation. β Type: Insecticide only (not rodenticide/herbicide). |
Base: 0% Add-on: 25% Total: 25% |
3808.91.25.01 |
Other Aromatic Insecticides: Containing any aromatic or modified aromatic insecticide (not specifically listed in 3808.91.15) | β Non-Specific: If the thiazolone compound is different from the one in 3808.91.15.00. β General Category: Other aromatic insecticides not explicitly named. |
Base: 6.5% Add-on: 25% Total: 31.5% |
π Key Insight:
- The difference between 25% and 31.5% hinges on chemical specificity.
- If your active ingredient is N-[[[(4-chlorophenyl)amino]-carbonyl]-2,6-difluorobenzamide, use3808.91.15.00.
- If it is a different thiazolone derivative or a generic aromatic insecticide, use3808.91.25.01.

| β Packing List | βοΈ | Show net/gross weight, container size, and number of packages. |
| β Certificate of Origin | βοΈ | Required to verify China origin for Section 301 tariffs. |
β 2. Declaration Tips
π₯ Golden Rule:
"Chemical Specificity Determines Tariff; EPA Approval Ensures Entry."
| Scenario | Correct Declaration | Risk of Error |
|---|---|---|
| Product contains N-[[[(4-chlorophenyl)amino]-carbonyl]-2,6-difluorobenzamide | Declare as 3808.91.15.00 with full chemical name |
If misdeclared as "Other Aromatic Insecticide" β Overpay 6.5% |
| Product contains a different thiazolone compound | Declare as 3808.91.25.01 |
If misdeclared as specific mixture β Misclassification Penalty |
| Pure Active Ingredient (Not Formulated) | Do NOT use 3808.xx; use 2933.xx |
Using 3808 for pure chemicals β Wrong HS Code, Potential Smuggling Charge |
| Non-Retail Bulk Chemical | Check if it fits "Preparation" definition | Bulk industrial chemicals may have different classifications |
β 3. Special Considerations
| Issue | Advice |
|---|---|
| EPA Compliance | Ensure the product has EPA Registration before shipping. USDA/APHIS may also require phytosanitary certificates if plant residues are present. |
| Chemical Name Accuracy | Use IUPAC name exactly as it appears in HTSUS note for 3808.91.15.00. Spelling errors can lead to rejection. |
| Mixed Shipments | If a shipment contains both 3808.91.15.00 and 3808.91.25.01, separate declarations are required. Do not consolidate under one code. |
| Section 301 Exclusions | Check if any specific exclusion numbers apply to your product. Most chemical preparations are not excluded. |

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
