Products classified under HTS 3824.50.00.50
Polymer-Based Non-Refractory Mortar Mix
A ready-to-use mortar mix containing polymer additives and fine aggregates, designed for construction applications like bricklaying and plastering where high adhesion is needed. It falls under HTS 3824.50.0050 as a non-refractory mortar not elsewhere specified, consisting of chemical preparations from the chemical industries. This classification applies to pre-mixed formulations without refractory properties.
Cementitious Grout for Tile Installation
A non-refractory cement-based grout used to fill joints between ceramic tiles, offering water resistance and flexibility. Classified under HTS 3824.50.0050 as 'other' non-refractory mortars and concretes from chemical preparations. It is not for refractory use and is pre-mixed for construction.
Ready-Mix Repair Concrete Patch
A quick-setting, non-refractory concrete preparation for patching cracks in concrete surfaces, containing polymers and accelerators. It is classified in HTS 3824.50.0050 as other non-refractory concretes from chemical industries. Used in construction maintenance, not high-temperature applications.
Epoxy-Modified Thinset Mortar
A latex and epoxy-fortified thinset mortar for bonding tiles to substrates in wet areas, providing superior adhesion. Falls under HTS 3824.50.0050 as non-refractory mortar preparations from chemical industries, not specified elsewhere. Ideal for flooring and walls without refractory needs.
Self-Leveling Underlayment Compound
A pourable, non-refractory concrete-like compound that levels subfloors before tile or flooring installation. Classified under HTS 3824.50.0050 as other non-refractory concretes, being a chemical preparation for construction. Dries to a smooth, durable surface.
Pre-Mixed Stucco Repair Mortar
A non-refractory, lime-based mortar for repairing exterior stucco walls, offering breathability and weather resistance. It is under HTS 3824.50.0050 as other non-refractory mortars from chemical preparations. Used in architectural restoration.
Acrylic Polymer Concrete Additive
A concentrated acrylic dispersion mixed into concrete for non-refractory mortars, enhancing flexibility and waterproofing. Classified in HTS 3824.50.0050 as other non-refractory concrete preparations. Primarily for admixture in construction mixes.
Non-Shrink Precision Grout
A cementitious, non-refractory grout for machinery base installation, expanding slightly to fill voids precisely. Falls under HTS 3824.50.0050 as other non-refractory grouts/mortars. Used in industrial equipment mounting.
Latex-Modified Patching Compound
A non-refractory mortar compound with latex for interior wall hole repairs, offering strong bonding and crack resistance. Classified under HTS 3824.50.0050 as other construction preparations. Suitable for DIY and professional use.
Hydrated Lime Mortar Mix
A pre-blended non-refractory mortar using hydrated lime for historic building restoration, allowing moisture vapor transmission. Under HTS 3824.50.0050 as other non-refractory mortars from chemical industries. Breathable for traditional masonry.
