Sandpaper Metal Polishing Disc

A sandpaper metal polishing disc is an abrasive tool used for refining, cleaning, deburring, and polishing metal surfaces. It typically consists of a backing disc, an abrasive material (sandpaper), and often an adhesive or bonding agent. These discs are commonly attached to angle grinders, rotary tools, or dedicated polishing machines.

Material:

• Backing: Commonly made of fiber, nylon, or phenolic resin providing structural support and flexibility.
• Abrasive: Aluminum oxide is the most frequent abrasive used for general metal polishing due to its cost-effectiveness and versatility. Silicon carbide offers faster cutting and is suitable for harder metals and aggressive material removal. Zirconia alumina is used for heavier duty applications, offering high durability and long life. Ceramic abrasives provide the highest cutting force and longest life but are generally more expensive.
• Bonding Agent: Resin, glue, or a combination of both secures the abrasive particles to the backing.

Purpose:

• Deburring: Removing sharp edges and imperfections from cut or machined metal.
• Cleaning: Eliminating rust, scale, paint, and other surface contaminants.
• Polishing: Achieving a smooth, reflective finish on metal surfaces.
• Surface Preparation: Creating a suitable surface for coatings, welding, or other finishing processes.
• Grinding: Removing material and shaping metal (though typically coarser grits are used for this purpose).

Function:

The disc functions by utilizing the abrasive particles bonded to the backing material. As the disc rotates against the metal surface, the abrasive particles remove material through micro-shearing and abrasion. The grit size of the sandpaper determines the aggressiveness of the material removal and the final surface finish. Lower grit numbers indicate coarser abrasives for faster material removal, while higher grit numbers indicate finer abrasives for polishing and smoothing.

Usage Scenarios:

• Automotive: Polishing car bodies, removing rust from frames, and preparing surfaces for paint.
• Metal Fabrication: Deburring welds, smoothing metal edges, and polishing metal components.
• Construction: Removing rust and scale from metal structures, preparing surfaces for coatings.
• Woodworking: Refinishing metal hardware and components. (Less common, but applicable)
• DIY Projects: Restoring metal furniture, cleaning tools, and polishing metal art pieces.

Common Types:

• Flap Discs: Constructed with overlapping abrasive flaps, providing a flexible and aggressive cutting action. Suitable for grinding, deburring, and blending.
• Fiber Discs: Made with abrasive particles embedded in a fiber backing. Offer high strength and durability, ideal for heavy-duty grinding and deburring.
• PSA (Pressure Sensitive Adhesive) Discs: Feature an adhesive backing for easy attachment to backing pads. Commonly used for finer polishing and sanding operations.
• Surface Conditioning Discs (Scotch-Brite Discs): Utilize non-woven abrasive material for cleaning, blending, and finishing. Provide a consistent finish and are less likely to leave scratches.
• Diamond Polishing Discs: Incorporate diamond abrasive particles for polishing extremely hard metals and achieving a high-gloss finish. More expensive but offer superior performance and longevity.

Sandpaper metal polishing discs are abrasive products used for surface treatment, typically consisting of abrasive particles bonded to a base material (paper, textile, or other materials) and formed into a disc shape for polishing metal surfaces.

The following HS codes may be relevant:

• 6805.10.00.00: This code covers natural or artificial abrasive powder or grain on a base of textile fabric. This is applicable if the disc’s base material is woven textile fabric. The total tax rate is 55.0%, comprising a 0.0% base tariff, a 25.0% additional tariff, and a 30% additional tariff effective after April 2, 2025.
• 6805.30.10.00: This code covers natural or artificial abrasive powder or grain on a base of other materials, specifically articles wholly or partly coated with abrasives in the form of sheets, strips, disks, belts, sleeves, or similar forms. This applies if the base material is not textile fabric. The total tax rate is 55.0%, comprising a 0.0% base tariff, a 25.0% additional tariff, and a 30% additional tariff effective after April 2, 2025.

Chapter 68 relates to articles of stone, plaster, lime, cement, asbestos, mica or similar materials. Heading 6805 specifically covers abrasive products.

It is important to determine the exact base material of the sandpaper metal polishing disc to select the correct HS code.
