Products classified under HTS 7603.20.00.00
Aluminum Leafing Flakes
These are thin, flat aluminum flakes with a lamellar structure designed for leafing in paints and coatings, where they align parallel to the surface to create a metallic sheen. Classified under HTS 7603.20.00.00 as aluminum flakes of lamellar structure used primarily in industrial coatings. They meet the definition of aluminum powders and flakes due to their thin, plate-like form.
Micronized Aluminum Flakes for Automotive Paint
Fine aluminum flakes around 10-20 microns thick with lamellar structure, optimized for automotive metallic basecoats to provide sparkle and durability. Falls under HTS 7603.20.00.00 as powders of lamellar structure specifically for paint applications. Their flat, platelet shape distinguishes them from spherical powders.
Aluminum Pigment Flakes 20 Micron
Lamellar aluminum flakes sized at 20 microns, non-leafing type used in industrial paints for uniform metallic effects without surface floating. Classified in HTS 7603.20.00.00 for their flake structure ideal for pigment dispersion. Purity meets aluminum powder definitions without alloying.
Super Leafing Aluminum Flakes for Industrial Coatings
High leafing grade aluminum flakes with pronounced lamellar structure for protective industrial coatings like roof paints and marine finishes. HTS 7603.20.00.00 applies to these flake powders due to their thin, plate-like morphology. Used for barrier properties via alignment in solvent-based systems.
Aluminum Flake Powder for Plastics Pigmentation
Lamellar flakes treated for dispersion in thermoplastics, providing metallic luster in molded plastic parts like automotive trim. Under HTS 7603.20.00.00 as powders of lamellar structure before compounding into plastics. Flake shape enables orientation for aesthetic effects.
Dutch Gold Aluminum Flakes
"Dutch gold" grade lamellar aluminum flakes historically used for imitation gold leaf in decorative paints and inks. HTS 7603.20.00.00 covers these fine flakes with classic lamellar structure. Ideal for achieving antique metallic finishes.
Fine Aluminum Lamellar Powder for Explosives
Ultra-fine lamellar aluminum powder (5-10 microns) used as fuel in pyrotechnics and explosives for enhanced burn rate. Classified HTS 7603.20.00.00 for flake structure providing high surface area. Meets non-alloyed aluminum per chapter note (a).
Aluminum Flakes for Intaglio Printing Inks
Medium coarse lamellar flakes for security printing inks, providing metallic security features in currency and documents. HTS 7603.20.00.00 due to distinct flake morphology for ink alignment. High opacity and reflection properties.
Passivated Aluminum Flakes for Aerospace Coatings
Lamellar flakes with silica passivation for corrosion resistance in aerospace topcoats and primers. Under 7603.20.00.00 as base aluminum flakes despite treatment, per chapter notes prioritizing material form. Enables MIL-spec durability.
Silver Dollar Aluminum Flakes
Large particle lamellar flakes (20-40 microns) resembling silver dollars, used in heavy-duty roof coatings for maximum leafing. HTS 7603.20.00.00 for their prominent flake structure and aluminum purity. Provides superior UV reflection.
Corn Flake Aluminum Pigment
Corn flake-shaped lamellar aluminum particles for hammer finish effect paints, creating textured metallic appearance. Classified 7603.20.00.00 for irregular lamellar flake structure. Popular in decorative architectural coatings.
Aluminum Flakes for Mirror Effect Coatings
Ultra-thin lamellar flakes (<1 micron thick) for high-chroma mirror finishes in cosmetic packaging and chrome alternatives. HTS 7603.20.00.00 applies to these premium flakes maximizing reflection. Enables plastic-to-metal aesthetics.
Granular Aluminum Leafing Flakes
Coarse lamellar flakes in granular paste form for easy mixing in high-solids coatings. Under 7603.20.00.00 as the aluminum component retains flake structure despite carrier. Used in traffic marking paints.
Aluminum Flake for Powder Coatings
Dry lamellar aluminum flakes optimized for powder coating extrusion, surviving high shear for metallic finishes on appliances. HTS 7603.20.00.00 for dry flake powders pre-compounding. Bonded types use minimal stearate.
High Purity Lamellar Aluminum Powder 99.9%
99.9% pure lamellar aluminum powder for analytical and R&D applications requiring flake morphology. Precisely meets HTS 7603.20.00.00 and chapter note (a) for non-alloyed aluminum. Used in advanced materials research.
