πΏ Pyrazole Fungicide β Comprehensive HS Code & Tariff Guide (2026 Edition)
π HS Code Classification & Customs Clearance Strategy | 2026 Updated Tariff Breakdown | Expert-Level Import Compliance
π One Product, Four Critical HS Codes β Know Exactly Where It Belongs!
Pyrazole fungicides are a class of advanced agricultural chemicals used to combat fungal diseases in crops. These compounds are highly effective due to their unique non-fused pyrazole ring structure or nitrogen-containing heterocyclic frameworks, making them essential in modern crop protection.
However, misclassification can lead to massive tariff overpayments, delays, or even seizure. Below is the definitive, data-driven guide based on real-time customs data, with full tax breakdowns, legal references, and actionable clearance strategies.
π¦ 1. HS Code Classification Breakdown (2026 Official Tariff Data)
| HS Code | Product Description | Key Structural Feature | Applicable Use Case | Tax Rate |
|---|---|---|---|---|
2933.19.23.00 |
Pyrazole fungicide, non-fused pyrazole ring structure, for pesticide use | Non-fused pyrazole ring | Broad-spectrum fungicide in agriculture | 41.5% |
2933.39.21.00 |
Pyrazole fungicide, nitrogen-containing heterocyclic structure, meets fungicidal criteria | Nitrogen heterocycle | Targeted fungal control, e.g., powdery mildew | 16.5% |
3808.92.15.00 |
Pyrazole fungicide, aromatic or modified aromatic structure | Aromatic backbone | High-performance fungicides in crop protection | 41.5% |
3808.92.50.80 |
Pyrazole fungicide, classified as fungicidal agent, not IPBC-specific | Non-IPBC fungicidal active ingredient | General fungicide applications | 40.0% |
β οΈ Critical Insight:
- Same active ingredient, different chemical structure β different HS codes β drastically different tariffs
- Do not assume all pyrazole fungicides are the same. Structure matters.
π° 2. 2026 Tariff Breakdown β Full Tax Clause Analysis (U.S. Import Focus)
β Applicable Country: United States (US)
β Origin: China (CN)
β Effective Date: November 10, 2025 (including future imports)
π― 1. 2933.19.23.00 β Non-Fused Pyrazole Ring, Pesticide Use
| Tax Component | Rate | Legal Basis | Explanation |
|---|---|---|---|
| Base Tariff | 6.5% | Section 301 Tariff Schedule | Standard duty on chemical intermediates |
| Section 301 (USITC) Add-on | +25.0% | USITC Footnote 9903.88.01 | Tariff from U.S. Trade Act 301 (China-related) |
| IEEPA (Emergency Powers) Add-on | +10.0% | IEEPA: 9903.01.25 | International Emergency Economic Powers Act β applies to China-origin goods |
| Total Effective Tariff | 41.5% | β | CIF Value Γ 41.5% |
| De Minimis Threshold | β Not applicable | β | No de minimis exemption for China-origin goods |
| Legal Pathway | IEEPA:9903.01.25 β USITC:9903.88.01 β 2933.19.23.00 |
π Why This Rate Applies:
- The non-fused pyrazole ring is classified under 2933.19.23.00, which is subject to 301 + IEEPA tariffs due to its pesticide function and Chinese origin.
π― 2. 2933.39.21.00 β Nitrogen-Containing Heterocycle, Fungicidal Use
| Tax Component | Rate | Legal Basis | Explanation |
|---|---|---|---|
| Base Tariff | 6.5% | Section 301 Tariff Schedule | Standard chemical duty |
| Section 301 (USITC) Add-on | +0.0% | USITC Footnote 9903.88.01 | No 301 tariff for this specific subheading |
| IEEPA (Emergency Powers) Add-on | +10.0% | IEEPA: 9903.01.25 | Applies regardless of 301 status |
| Total Effective Tariff | 16.5% | β | CIF Value Γ 16.5% |
| De Minimis Threshold | β Not applicable | β | Still no de minimis for China-origin |
| Legal Pathway | IEEPA:9903.01.25 β 2933.39.21.00 |
π Why This Rate Is Lower:
- Although still subject to IEEPA 10%, this code does not trigger the 25% Section 301 tariff due to structural classification under 2933.39.21.00 (nitrogen heterocycle).
π― 3. 3808.92.15.00 β Aromatic/Modified Aromatic Pyrazole Fungicide
| Tax Component | Rate | Legal Basis | Explanation |

| Legal Pathway | IEEPA:9903.01.25 β USITC:9903.88.01 β 3808.92.50.80 |
π Why This Rate Applies:
- Non-IPBC classification means it avoids IPBC-specific restrictions, but still falls under 301 and IEEPA due to fungicidal function and origin.

π 5. Common Mistakes & How to Avoid Them
β Mistake 1: Using βfungicideβ as the only description
π Result: Customs may assume 2933.19.23.00 β 41.5% tax
β
Fix: Include chemical structure in description:
"Pyrazole fungicide, non-fused ring, 98% purity, for agricultural use, HS: 2933.19.23.00"
β Mistake 2: Not providing structure diagram
π Result: Delayed clearance, possible reclassification
β
Fix: Attach PDF of molecular structure with invoice
β Mistake 3: Assuming all pyrazole fungicides are the same
π Result: Pay 41.5% when only 16.5% applies
β
Fix: Verify ring structure beforeη³ζ₯
π― 6. Final Verdict: Maximize Savings, Minimize Risk
πΉ Structure determines tax β not brand, not name, not function alone
πΉ 2933.39.21.00 is your lowest-tax option (16.5%) if nitrogen heterocycle
πΉ 3808.92.50.80 is best for non-IPBC formulations (40.0%)
πΉ Avoid 301/IEEPA tariffs by sourcing from Vietnam/Mexico/Thailand
π£ Action Now: Secure Your Shipment, Lock in Savings!
π Contact a U.S. Customs Broker + Submit Structure + Request Pre-Ruling

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
