Find HS Code and trade information for solid glue

Solid Glue

Solid glue refers to adhesive substances that are in a solid or semi-solid state at room temperature. These adhesives require activation, typically through heat, pressure, or a solvent, to become liquid and capable of bonding materials.

Material Composition

Solid glues encompass a broad range of materials, categorized by their chemical base:

• Hot Melt Adhesives: Primarily composed of thermoplastic polymers (e.g., ethylene-vinyl acetate (EVA), polyolefin, polyamide). These melt upon heating and solidify upon cooling.
• Pressure-Sensitive Adhesives (PSAs): Based on viscoelastic polymers, often acrylics, rubbers, or silicones. They bond with applied pressure.
• Epoxy Adhesives (Two-Part): Consist of an epoxy resin and a hardener. Mixing initiates a chemical reaction, creating a strong, durable bond.
• Cyanoacrylate Adhesives (Super Glue): Rapidly polymerize upon exposure to moisture, forming a strong bond.
• Polyurethane Adhesives: Available in one-part and two-part formulations, offering flexibility and resistance to various conditions.
• Wax Adhesives: Natural or synthetic waxes used for lower-temperature bonding applications.

Purpose and Function

The primary function of solid glue is to create a bond between two or more substrates through adhesion. Specific purposes vary depending on the type of glue:

• Bonding: Joining materials together permanently or semi-permanently.
• Sealing: Filling gaps and preventing the passage of fluids or gases.
• Coating: Providing a protective layer on surfaces.
• Encapsulation: Protecting sensitive components.
• Gasketing: Creating a seal between mating surfaces.

Usage Scenarios

Solid glues are used in a diverse range of applications across various industries:

• Packaging: Sealing cartons, boxes, and labels. (Hot melt adhesives)
• Bookbinding: Binding pages together. (Hot melt adhesives)
• Woodworking: Joining wood components. (Hot melt, epoxy, polyurethane)
• Electronics: Bonding and protecting electronic components. (Epoxy, cyanoacrylate)
• Automotive: Bonding interior and exterior parts. (Epoxy, polyurethane)
• Construction: Installing flooring, panels, and fixtures. (Polyurethane)
• Arts and Crafts: General purpose bonding and repairs. (Cyanoacrylate, hot melt)
• Medical: Bonding medical devices and components. (Epoxy, cyanoacrylate)

Common Types

• Glue Sticks: Primarily for paper and light materials, activated by heat from a glue gun. (Hot melt)
• Epoxy Putty: Two-part epoxy for filling gaps and repairing damaged surfaces. (Epoxy)
• Super Glue (Cyanoacrylate): Fast-setting adhesive for small repairs and bonding various materials.
• Double-Sided Tape: PSA for mounting and bonding lightweight materials.
• Wood Glue: Specifically formulated for wood bonding, often PVA-based.
• Polyurethane Construction Adhesive: High-strength adhesive for bonding various building materials.
• Hot Melt Glue Pellets/Blocks: Used in industrial glue guns for high-volume applications.

Solid glue, based on the provided information, can fall under several HS codes depending on its composition. Here's a breakdown of potential classifications:

• 3503.00.10.00: This HS code covers Gelatin (including gelatin in rectangular (including square) sheets, whether or not surfaceworked or colored) and gelatin derivatives; isinglass; other glues of animal origin, excluding casein glues of heading 3501: Fish glue. This applies if the solid glue is specifically fish glue. The tariff details are a base duty of 1.2¢/kg + 1.5%, a 7.5% additional tariff, and a 30.0% additional tariff post-April 2, 2025, resulting in a total tariff of 1.2¢/kg + 1.5% + 37.5%.
• 3503.00.55.50: This HS code covers Gelatin (including gelatin in rectangular (including square) sheets, whether or not surfaceworked or colored) and gelatin derivatives; isinglass; other glues of animal origin, excluding casein glues of heading 3501: Other Other. This applies to other types of gelatin-based glues. The tariff details are a base duty of 2.8¢/kg + 3.8%, a 7.5% additional tariff, and a 30.0% additional tariff post-April 2, 2025, resulting in a total tariff of 2.8¢/kg + 3.8% + 37.5%.
• 9602.00.10.40: This HS code covers Worked vegetable or mineral carving material and articles of these materials; molded or carved articles of wax, of stearin, of natural gums or natural resins, of modeling pastes, and other molded or carved articles, not elsewhere specified or included; worked, unhardened gelatin (except gelatin of heading 3503) and articles of unhardened gelatin: Worked unhardened gelatin and articles thereof Unfilled gelatin capsules. This applies if the solid glue is in the form of unfilled gelatin capsules. The tariff details are a base duty of 3.0%, a 7.5% additional tariff, and a 30.0% additional tariff post-April 2, 2025, resulting in a total tariff of 40.5%.
• 9602.00.10.80: This HS code covers Worked vegetable or mineral carving material and articles of these materials; molded or carved articles of wax, of stearin, of natural gums or natural resins, of modeling pastes, and other molded or carved articles, not elsewhere specified or included; worked, unhardened gelatin (except gelatin of heading 3503) and articles of unhardened gelatin: Worked unhardened gelatin and articles thereof Other. This applies to other forms of worked unhardened gelatin. The tariff details are a base duty of 3.0%, a 7.5% additional tariff, and a 30.0% additional tariff post-April 2, 2025, resulting in a total tariff of 40.5%.

According to the provided reference material, the HS code options related to 'solid glue' are limited, with only the following 4 found.

It is important to determine the exact composition of the solid glue to select the correct HS code. If the glue is animal-based, codes starting with 3503 should be considered. If it's a different material, codes starting with 9602 might be more appropriate.
