π I. Product Definition & Classification: What Exactly Is This Product?
The product is described as an "Inorganic Salt containing Forest Plant Growth Regulator." This is a complex commodity that sits at the intersection of chemical salts and agricultural/forestry additives.
Crucial Distinction:
Pure Inorganic Salts (Chapter 28): Classified by chemical composition (e.g., Sulfates, Nitrates) without functional additives.
* Plant Growth Regulators/Fertilizers (Chapter 31):* Classified by their agricultural function, especially when mixed or prepared for specific growth effects.
β οΈ Key Regulatory Conflict:
- If the product is primarily a chemical salt with minor additive effects β Chapter 28 (e.g., Sulfates).
- If the product is prepared/used for agricultural purposes (forestry fertilization/growth regulation) β Chapter 31 (Fertilizers).
- Strict Constraint: The provided reference data does not contain a specific HS code for "Plant Growth Regulators" in Chapter 28. It only lists generic inorganic salts and a specific entry for Chapter 31. Therefore, classification depends on the primary purpose and composition as per the provided reference.
π¦ II. HS Code Classification Details (Based on Provided Reference)
| HS Code | Product Description | Applicability | Why This Code? |
|---|---|---|---|
2833.19.00.00 |
Sulfates; alums; peroxosulfates: Sodium sulfates: Other | If the base salt is Sodium Sulfate | Matches "Inorganic Salt" structure. If the growth regulator is considered a minor additive or mixture not defined in Chapter 28, sodium sulfate is the primary chemical carrier. |
2833.29.51.90 |
Sulfates; alums; peroxosulfates: Other sulfates: Other: Other | If the base salt is a generic inorganic sulfate (not Na, Mg, Al, etc.) | Used if the salt is not specified in other 2833 subheadings. Covers "Other" sulfates. |
3105.90 |
Fertilizers containing inorganic salts and plant growth regulators | If classified as an Agricultural Product | Most likely match for "Forest Plant Growth Regulator". The reference explicitly describes this as "Inorganic salts containing forest plant growth regulators, classified under fertilizers...". |
2840.00 |
Inorganic salts and peroxides (broad category) | Fallback for unspecified chemical salts | Mentioned in reference but less specific than 2833 or 3105 for sulfates/regulators. |
π Critical Analysis:
- The reference explicitly states for3105.90: "Inorganic salts containing forest plant growth regulators, classified under fertilizers...".
- This makes3105.90the most accurate classification if the productβs intended use is agricultural/forestry growth regulation.
- Codes2833.19.00.00and2833.29.51.90are only applicable if the product is deemed a pure chemical salt (Chapter 28) rather than a fertilizer/preparation (Chapter 31). However, the presence of a "growth regulator" strongly pushes it toward Chapter 31.
π° III. 2026 Latest Tariff Rate Details
π― 1. 3105.90 β Fertilizers Containing Plant Growth Regulators
(Most Likely Classification)
| Item | Content |
|---|---|
| Base Tariff | Error (Failed to retrieve from reference) |
| Total Tax | Error (Failed to retrieve from reference) |
| Tax Detail | Not specified in reference |
| Legal Basis | Reference description: "Fertilizers of a kind used for agricultural purposes..." |
π Explanation:
- The reference fails to provide tax data for3105.90.
- Risk: Without tax data, customs clearance may be delayed for valuation or tariff application.
- Recommendation: Assume standard Chapter 31 rates if not specified, but verify with local customs due to the "Error" flag.
- Note: If this code is used, it implies the product is not subject to Chapter 28 sulfate tariffs but rather agricultural fertilizer tariffs.
π― 2. 2833.19.00.00 β Sodium Sulfates (Other)
(Alternative Classification if Deemed Chemical Salt)
| Item | Content |
|---|---|
| Base Tariff | 0.0% |
| Additional Tariff | 25.0% |
| Total Tax | 25.0% |
| Tax Detail | "εΊη‘ε ³η¨: 0.0%, ε εΎε ³η¨: 25.0%" |
| Legal Basis | Chapter 28 β Inorganic Chemicals |
π Explanation:
- If classified under Chapter 28 (Sodium Sulfate), the 25% additional tariff applies.
- This is significantly higher than standard fertilizer tariffs (often 0-5%).
- Warning: Misclassifying a growth regulator product as a simple sulfate could lead to underpayment of duties if the correct code is3105.90with different rates, or overpayment if3105.90has a lower rate.
π― 3. 2833.29.51.90 β Other Sulfates (Other)
(Alternative Classification)
| Item | Content |
|---|---|
| Base Tariff | 0.0% |
| Additional Tariff | 0.0% |
| Total Tax | 0.0% |
| Tax Detail | "εΊη‘ε ³η¨: 0.0%, ε εΎε ³η¨: 0.0%" |
| Legal Basis | Chapter 28 β Inorganic Chemicals |
π Explanation:
- If the salt is an unspecified sulfate and classified here, the tariff is 0%.
- However, this code is less likely if the product contains a "growth regulator," as regulatory bodies often prioritize Chapter 31 for such mixtures.
π οΈ IV. Customs Clearance Practical Advice (Avoiding Pitfalls)
β 1. Documentation Checklist (Must-Have)
| Document | Required? | Purpose |
|---|---|---|
| Product Formula/Composition | β Critical | To prove whether the "growth regulator" is a major component (β Ch. 31) or minor additive (β Ch. 28). |
| Safety Data Sheet (SDS) | β Required | Shows chemical hazards and composition. |
| Certificate of Analysis (COA) | β Required | Confirms active ingredients and concentrations. |
| Intended Use Statement | β Required | Must state: "Used for forest plant growth regulation" to support 3105.90. |
| Commercial Invoice | β Required | Must describe product as "Inorganic Salt with Forest Plant Growth Regulator". |
| Import License (Agricultural) | β Likely Required | Chapter 31 products often require agricultural import permits. |
β 2. Classification Strategy (Key Decision Tree)
π₯ "Function Over Form: Is it a Fertilizer or a Chemical?"
| Scenario | Recommended HS Code | Reason |
|---|---|---|
| Primary Use: Forestry growth regulation, soil amendment | 3105.90 |
Reference explicitly links "plant growth regulator" to Chapter 31 fertilizers. |
| Primary Use: Industrial chemical process, regulator is trace impurity | 2833.19.00.00 or 2833.29.51.90 |
Classified by chemical base (Sodium Sulfate or Other Sulfate). |
| Unclear/Disputed | 3105.90 |
Safer Option: Agricultural products often face stricter scrutiny, but misclassification as a chemical may lead to penalties for evading agricultural controls. |
β 3. Special Considerations
| Issue | Handling Advice |
|---|---|
Tax Data Missing for 3105.90 |
Contact Customs Broker Immediately. Do not assume 0%. Verify with local customs authority. |
25% Additional Tariff on 2833.19 |
If classified here, ensure the 25% tariff is budgeted. This is a significant cost. |
| Regulatory Approval | Plant growth regulators are often controlled substances. Ensure EPA/USDA (or local equivalent) approval is in place. |
| Misclassification Risk | Declaring as 2833 to avoid agricultural regulations while using as 3105 is fraud. Penalties can include seizure and fines. |
π V. Global Market Comparison (2026)
| Country/Region | Recommended HS Code | Tariff Rate | Certification | Notes |
|---|---|---|---|---|
| πΊπΈ USA | 3105.90 |

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
