π§ͺ Interface Glues & Adhesives (Prepared Adhesives & Self-Adhesive Plastic Products)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
π I. Product Definition & Classification: What Exactly is "Interface Glue"?
"Interface Glue" is a broad commercial term that can refer to various types of bonding agents depending on the application context (e.g., electronic assembly, display manufacturing, construction, or general retail). In international trade, these products are primarily classified under Chapter 35 (Animal Glues & Organic Adhesives) or Chapter 39 (Plastics and Articles Thereof) if they are self-adhesive tapes/films.
The critical distinction lies in the chemical base (polymer/rubber vs. other) and packaging form (liquid paste vs. solid roll/film).
β οΈ Key Distinction Point:
- If the product is a liquid or paste adhesive based on polymers (3901-3913) or rubber βε½ε ₯ Chapter 35 (e.g., 3506).
- If the product is a self-adhesive plastic tape/film/roll (even if it's an "interface" tape) βε½ε ₯ Chapter 39 (e.g., 3919).
- If it is a filler/putty not specified as glue βε½ε ₯ Chapter 32 (e.g., 3214).
π¦ II. HS Code Classification Details (2026 Latest Tariff Authoritative Comparison)
Based on the provided data, here are the specific HS Codes for "Interface Glues" and related adhesive products, along with their tax implications for imports from China to the US (or general context as per data).

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
