Products classified under HTS 3808.93.20.00
Copper Sulfate Pentahydrate Herbicide
A blue crystalline powder containing copper sulfate (CuSO4·5H2O), an inorganic compound used as a herbicide to control aquatic weeds and algae in ponds and irrigation canals. It is put up in retail packs for gardeners and farmers, falling under HTS 3808.93.20.00 because it is a herbicide preparation containing an inorganic substance. The product disrupts photosynthesis in target plants through copper ion release.
Sodium Chlorate Weed Killer Spray
A ready-to-use spray formulation containing sodium chlorate (NaClO3), an inorganic oxidizing agent that desiccates and kills broadleaf weeds on driveways and paths. Packaged in aerosol cans for retail sale to homeowners, it qualifies under HTS 3808.93.20.00 as a herbicide with inorganic active substance. The strong oxidizer breaks down plant cell structures upon contact.
Ammonium Sulfamate Granular Herbicide
Water-soluble granules of ammonium sulfamate ((NH4)2SO3), an inorganic salt herbicide effective against woody plants and poison ivy when dissolved and sprayed. Sold in 1kg retail bags for backyard use, it fits HTS 3808.93.20.00 as a plant regulator/herbicide with inorganic substance. It acts systemically to inhibit enzyme activity in target plants.
Boric Acid Ant and Weed Control Powder
Dustable powder containing boric acid (H3BO3), an inorganic boron compound that kills weeds and repels insects when applied to soil or cracks. Retail shaker containers make it suitable for home use, classifying under HTS 3808.93.20.00 for herbicides with inorganic substances. It interferes with plant metabolism and insect digestion.
Potassium Arsenite Brush Killer
Liquid concentrate of potassium arsenite (KA3AsO3), a highly toxic inorganic arsenical herbicide for killing brush and invasive shrubs. Diluted for retail sprayer use by landowners, it is covered by HTS 3808.93.20.00 as a herbicide containing inorganic substance. Arsenic ions poison plant enzyme systems.
Sodium Metaborate Sprout Suppressant
Powdered sodium metaborate (NaBO2) applied to potato storage to prevent sprouting, acting as an anti-sprouting plant-growth regulator. Retail packs for small-scale farmers fit HTS 3808.93.20.00 as it contains an inorganic substance for such use. Boron inhibits cell division in sprout buds.
Calcium Cyanamide Plant Growth Regulator
Granular calcium cyanamide (CaCN2), an inorganic compound used as a plant growth regulator to enhance nodulation in legumes and control weeds. Sold in retail bags for organic farming, it falls under HTS 3808.93.20.00. Upon hydrolysis, it releases cyanamide which affects plant hormones.
Ferric Phosphate Slug and Weed Bait
Iron(III) phosphate (FePO4) bait pellets targeting slugs while providing residual weed suppression through phosphate disruption. Consumer garden packs qualify for HTS 3808.93.20.00 as inorganic herbicide preparation. Low-toxicity iron binds in mollusk digestion.
Zinc Phosphide Rodent/Herbicide Granules
Zinc phosphide (Zn3P2) granules for gopher control with secondary weed desiccation effect, in retail bait stations. Inorganic substance qualifies under HTS 3808.93.20.00 for herbicide use. Phosphine gas released kills on ingestion.
Magnesium Phosphide Fumigant Herbicide
Tablets of magnesium phosphide (Mg3P2) generating phosphine gas for soil fumigation against weed seeds and nematodes. Retail packs for orchard use fit HTS 3808.93.20.00. Inorganic substance provides contact/systemic weed kill.
Sodium Fluoride Termite/Weed Barrier
Dust containing sodium fluoride (NaF) for soil treatment creating barriers against termites and weed root intrusion. Retail applicator bottles classify under HTS 3808.93.20.00. Fluoride ions disrupt plant calcium metabolism.
Aluminum Phosphide Orchard Herbicide
Aluminum phosphide (AlP) pellets for pre-plant soil fumigation killing weed seeds in orchards. Retail hermetic pouches qualify for HTS 3808.93.20.00. Phosphine penetrates soil profile effectively.
Cupric Hydroxide Bactericide/Herbicide
Suspension concentrate of cupric hydroxide (Cu(OH)2) for citrus canker control with weed suppression. Retail spray bottles under HTS 3808.93.20.00. Inorganic copper provides multi-action control.
Strontium Chlorate Desiccant Herbicide
Strontium chlorate (Sr(ClO3)2) spray for cotton defoliation and weed desiccation at harvest. Retail measures fit HTS 3808.93.20.00. Oxidizer rapidly dries plant tissue.
Mercuric Chloride Seed Treatment Herbicide
Dilute mercuric chloride (HgCl2) solution for seed dressing preventing fungal diseases and weed competition. Highly regulated retail kits under HTS 3808.93.20.00. Inorganic mercury disinfects and regulates growth.
