π¦ I. Product Definition & Classification: What Exactly Is This Resin?
Thermosetting Acrylic Modified Petroleum Resin is a high-performance synthetic resin formed by chemically modifying petroleum-based resins (like petroleum resins or coumarone-indene resins) with acrylic monomers. It is thermosetting, meaning it undergoes irreversible cross-linking when heated, forming a rigid, durable, and chemically resistant network.
This resin is widely used in: - High-performance adhesives (e.g., industrial bonding) - Coatings and inks (especially UV-curable and high-heat-resistant types) - Sealants and composite materials - Automotive and aerospace applications
β οΈ Key Classification Clue:
- Contains aromatic or modified aromatic monomer units
- Derived from petroleum resins
- Thermosetting in nature
- Not elsewhere specified or included (i.e., doesnβt fit into more specific subheadings)
π Therefore, it falls under HS Code 3911.90.45.00 β the correct and precise classification.

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
