πΏ Plant Adhesive (Botanical Glues & Stems)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Import Strategy
Plant Adhesive is a niche but growing category in the botanical, floriculture, and craft industries. It refers to adhesives derived from natural plant sources (such as starch, cellulose, or natural resins) or specialized bio-based glues used to bind plant materials, preserve flowers, or attach artificial stems.
β οΈ Critical Distinction:
- If the product is a pure natural adhesive (e.g., starch-based paste, natural latex), it may fall under Chapter 35 (Albuminoidal Substances) or Chapter 38 (Miscellaneous Chemical Products).
- If it is a synthetic-based adhesive with plant-derived additives, it likely falls under Chapter 35 or 39 (Plastics).
- If it is a finished floristβs tool (e.g., floral tape with adhesive backing), it may be classified under Chapter 48 (Paper) or Chapter 39 (Plastics).
- Most commonly, commercial "Plant Adhesives" (bio-based, non-toxic, for crafts/flower arranging) are classified under 3506.91 or 3506.99.
π¦ HS Code Classification Details (2026 Latest Tariff Authority Cross-Reference)
| HS Code | Product Description | Application Scenario | Base Material |
|---|---|---|---|
3506.91.00.00 |
Adhesives prepared on the basis of starches or glucomannans | Traditional botanic glue, flower preserving paste, paper-based plant mounting | β Starch/Glucomannan |
3506.99.00.00 |
Other prepared adhesives, not elsewhere specified | Bio-based resins, natural latex adhesives, mixed plant-derived glues | β Plant-derived Resins/Latex |
3901.10.00.00 |
Polymers of ethylene (if synthetic base) | Synthetic plant-safe glues with plant-derived labeling | β Synthetic |
3906.90.00.00 |
Other acrylic polymers | Fast-drying floral adhesives with synthetic backbone | β Synthetic |
4823.90.00.00 |
Other paper products (if floral tape/adhesive strips) | Adhesive-backed floral stems, paper-based plant ties | β οΈ Paper Base |
3824.99.00.00 |
Other chemical products (industrial grade) | Large-scale botanical extraction binders | β Mixed Chemical |
π Key Reminder:
- Bio-based claim: If marketed as "100% Natural" or "Plant-Based," ensure the primary binding agent is starch or natural resin. Otherwise, customs may classify it as synthetic.
- Florist Use: If sold as a "finished floral accessory" (e.g., pre-adhesive strips), it may shift to Chapter 48 or Chapter 39.
- Non-Toxic Certification: For plant safety, provide MSDS/SDS to prove no harmful synthetic solvents.

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
