🧪 Magnesium Rosin (Rosin Magnesium)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Clearance Strategy
📌 Part 1: Product Definition & Classification: What is "Magnesium Rosin"?
Magnesium Rosin (also known as Rosin Magnesium) is a chemical compound derived from the reaction of rosin (natural resin obtained from pine trees) with magnesium hydroxide or magnesium oxide. It is a white or light yellow powder, soluble in water and certain organic solvents.
In international trade, it is primarily classified as a chemical preparation or binding agent, not as a basic agricultural product or a simple metal salt. Its primary industrial applications include: * Paper Industry: As a sizing agent (to make paper water-resistant). * Adhesives & Sealants: As a prepared binding agent. * Textile & Soap Industry: As a hardener or stabilizer.
⚠️ Key Classification Point:
- It is NOT classified under Chapter 35 (Proteins) or Chapter 38 (Miscellaneous Chemical Products) as a basic magnesium salt (like Magnesium Sulfate).
- It is classified under Chapter 38 as a "Prepared Binding Agent or Chemical Preparation Not Elsewhere Specified."
- Misclassification Risk: Do NOT classify it as a fat/oil derivative (Chapter 15) or a basic chemical raw material (Chapter 29) unless it is a highly specific derivative not covered by Chapter 38.
📦 Part 2: HS Code Classification Details (2026 Latest Tariff Authority Comparison)
Based on the provided data, the following HS codes are potentially applicable. Note that 3824.90 is the primary and most accurate code for Magnesium Rosin in most jurisdictions.
| HS Code | Product Description | Applicable Scenario | Is it the Correct Code? |
|---|---|---|---|
3824.90 |
Chemical products of magnesium; prepared binding agents or chemical preparations not elsewhere specified. | Primary Classification: Magnesium Rosin used as a sizing agent, adhesive, or general chemical preparation. | ✅ YES (Most Likely) |
3511.90 |
Prepared animal or vegetable fats and oils; their fractions. (Potentially applicable if viewed as a modified rosin derivative used in specific industrial preparations). | Alternative/Incorrect: Only if the product is primarily a fat/oil with rosin additives, not a magnesium salt itself. | ❌ NO (Generally Incorrect for Magnesium Rosin) |
🔍 Critical Reminder:
- Magnesium Rosin is a metal salt of a resin acid, which falls under Chapter 38 (Miscellaneous Chemical Products).
- Headings 3511 refers to animal/vegetable fats and oils, which rosin is not (rosin is a resin).
- Therefore,3824.90is the correct classification.3511.90is likely a misclassification or applicable only to very specific, non-standard derivatives.

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