๐ HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
๐ I. Product Definition & Classification: Do You Really Understand "Chemical Adhesives"?
Chemical adhesives for molds are specialized bonding agents designed to join mold components, seal cavities, or repair damages in injection molding, die-casting, or compression molding setups. These adhesives often consist of polymers, rubber, or other chemical compounds that provide high heat resistance, pressure resistance, and chemical stability.
In international trade, these adhesives are categorized under Chapter 35: Albuminoidal Substances; Modified Starches; Glues; Enzymes, specifically focusing on Prepared Glues and Other Prepared Adhesives.
โ ๏ธ Key Distinction:
- If the adhesive is based on polymers of headings 3901 to 3913 or rubber, it falls under 3506.91 or 3506.99.
- The packaging size (retail sale โค 1 kg vs. > 1 kg) and specific polymer type determine the exact HS Code.
๐ฆ II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | Polymer/Rubber Basis | Retail Pack โค 1kg? |
|---|---|---|---|---|
3506.91.50.00 |
Adhesives based on polymers of headings 3901 to 3913 or on rubber: Other | Mold repair adhesives, polymer-based bonding agents | โ Polymers (3901-3913) or Rubber | โ Yes |
3506.99.00.00 |
Prepared glues and other prepared adhesives, not elsewhere specified or included: Other | General-purpose mold adhesives, non-specific polymer base | โ No (Other) | โ Yes |
๐ Key Reminder:
-3506.91.50.00applies if the adhesive is explicitly based on specific polymers (e.g., acrylics, epoxies, polyurethanes) or rubber.
-3506.99.00.00applies if the adhesive does not fall under the specific polymer/rubber categories or is a "mixed" adhesive not specified elsewhere.
- Packaging: Both codes assume the product is put up for retail sale as glues or adhesives, not exceeding a net weight of 1 kg.

๐ ๏ธ IV. Customs Clearance Practical Advice (ๅฎๆ้ฟๅๆๅ)
โ 1. Required Documents Checklist (No Exception)
| Document | Mandatory? | Description |
|---|---|---|
| โ Product Specification Sheet | โ๏ธ | Must detail chemical composition, polymer type, and intended use (mold adhesive). |
| โ MSDS/SDS (Safety Data Sheet) | โ๏ธ | Critical for chemical products; must specify hazards and handling instructions. |
| โ Commercial Invoice | โ๏ธ | Must clearly state "Chemical Adhesive for Molds" and HS Code. |
| โ Packing List | โ๏ธ | Specify net weight and packaging details (must be โค 1 kg for retail). |
| โ Certificate of Origin (CO) | โ๏ธ | If applicable, for potential tariff benefits (though not applicable here due to US-China trade tensions). |
| โ Labeling Information | โ๏ธ | Ensure labels comply with US chemical regulations (e.g., TSCA). |
โ 2. Declaration Tips (Key Mantras)

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