Products classified under HTS 3214.10.00.10
High-Performance MS Polymer Caulk
Modified silane (MS) polymer hybrid caulking for demanding joints, combining silicone and polyurethane benefits. As a caulking mastic, it fits HTS 3214.10.00.10 for construction gap sealing. UV-stable and isocyanate-free.
Silicone Caulking Compound
A flexible, waterproof sealant made from silicone polymers used for sealing gaps around windows, doors, and bathtubs in construction and home improvement. It falls under HTS 3214.10.00.10 as a caulking compound, specifically classified among mastics for its mastic-like properties in joint sealing. This product provides adhesion and elasticity without hardening fully.
Acrylic Latex Caulking Sealant
Water-based acrylic latex compound designed for interior sealing of gaps in drywall, trim, and woodwork, paintable after drying. Classified under HTS 3214.10.00.10 as a caulking compound due to its mastic properties for non-structural joints. It offers easy cleanup and flexibility for home repairs.
Polyurethane Construction Caulk
High-performance polyurethane-based caulking for exterior expansion joints in buildings, offering UV resistance and high elasticity. It is a mastic-type caulking compound under HTS 3214.10.00.10, distinct from glues due to its gap-filling application. Ideal for commercial construction sealing.
Butyl Rubber Caulking Compound
Synthetic rubber-based caulk for roofing and siding applications, providing excellent weatherproofing and low permeability. Falls under HTS 3214.10.00.10 as a caulking mastic, not a pure rubber product due to its compounded mastic form. Used in industrial and residential sealing.
Clear Silicone Kitchen & Bath Caulk
Transparent silicone caulking compound for sanitary sealing around sinks, showers, and countertops, mildew-resistant. Classified in HTS 3214.10.00.10 for its role as a flexible caulking mastic in wet areas. Dries to a rubber-like seal without cracking.
Paintable Acrylic Caulking for Trim
Low-odor, paintable acrylic latex caulk for baseboards, crown molding, and interior trim gaps. HTS 3214.10.00.10 covers it as a caulking compound mastic for non-structural filling. Allows seamless finishing after painting.
Outdoor Butyl Tape Caulking Compound
Roll-form butyl rubber caulking mastic applied via tape for RV, gutter, and flashing seals. HTS 3214.10.00.10 includes this as caulking compound despite tape format due to mastic composition. Self-adhering for weatherproofing.
Low-VOC Silicone Caulking for Green Building
Environmentally friendly silicone caulk with reduced volatile organic compounds for LEED-certified projects. Classified under HTS 3214.10.00.10 as caulking mastic meeting modern emission standards. Used in sustainable construction sealing.
