Products classified under HTS 3101.00.00.00
Organic Blood Meal Fertilizer
Blood meal is a dry, inert powder made from dried animal blood, primarily from cattle slaughterhouses, used as a high-nitrogen organic fertilizer. It falls under HTS 3101.00.00.00 because it is an animal-derived product chemically treated through drying and grinding for agricultural use. This nitrogen-rich amendment promotes vigorous leaf growth in gardens and crops.
Fish Emulsion Liquid Fertilizer
Fish emulsion is a liquid organic fertilizer produced by hydrolyzing fish carcasses with enzymes, providing nitrogen, phosphorus, and trace minerals. Classified under HTS 3101.00.00.00 as it's chemically treated from vegetable/animal (fish) products for plant nutrition. Ideal for foliar feeding and soil drenching in organic farming.
Bone Meal Granular Fertilizer
Bone meal consists of steamed bone meal ground into granules, serving as a slow-release phosphorus source for root development. It qualifies for HTS 3101.00.00.00 as an animal product (cow bones) chemically treated through steaming and milling. Commonly used in organic vegetable gardens and flower beds.
Worm Castings Organic Fertilizer
Vermicompost or worm castings are nutrient-rich soil amendment produced by earthworms digesting organic waste. Falls under HTS 3101.00.00.00 as vegetable-derived (plant matter) fertilizer through biological/chemical treatment in worm digestion. Excellent for improving soil structure and microbial activity.
Feather Meal Nitrogen Fertilizer
Feather meal is hydrolyzed poultry feathers processed into high-nitrogen (12-15%) organic fertilizer. Classified HTS 3101.00.00.00 for chemically treated animal (poultry) products serving as plant nutrient. Popular for heavy-feeding crops like corn and tomatoes.
Seaweed Kelp Meal Fertilizer
Kelp meal is dried, ground Ascophyllum nodosum seaweed providing potassium, trace minerals, and plant growth hormones. HTS 3101.00.00.00 covers this vegetable (marine algae) product dried/chemically treated for fertilizer use. Enhances stress tolerance and root growth.
Composted Chicken Manure Pellets
Pelletized chicken manure compost undergoes aerobic decomposition and pelletizing for odor-free, slow-release NPK fertilizer. HTS 3101.00.00.00 applies to chemically/biologically treated animal products. Balanced 4-3-2 nutrient profile for lawns and vegetables.
Alfalfa Meal Organic Fertilizer
Dehydrated alfalfa meal from ground legume hay offers 2.5% nitrogen plus triacontanol growth stimulant. Vegetable-origin product under HTS 3101.00.00.00 through dehydration/ grinding chemical treatment. Excellent for potassium-deficient soils.
Bat Guano Natural Fertilizer
Bat guano is accumulated bat feces mined from caves, naturally rich in nitrogen and phosphorus for organic gardening. Animal product under HTS 3101.00.00.00 with minimal processing (screening/grinding). High chitin content boosts beneficial microbes.
Neem Seed Cake Fertilizer
Neem cake is the residual seed pulp after neem oil extraction, used as slow-release NPK with natural pest repellent. Vegetable byproduct under HTS 3101.00.00.00 chemically treated via oil pressing. Improves soil nematodes control.
Cottonseed Meal Fertilizer
Cottonseed meal from oil-extracted cotton seeds provides 6% nitrogen and phosphorus for organic farming. Vegetable-derived under HTS 3101.00.00.00 after mechanical/chemical oil removal processing. Gossypol-free varieties safe for soil application.
Molasses-Based Liquid Fertilizer
Cane molasses fortified with micronutrients creates liquid carbohydrate energy source for soil microbes. Vegetable product (sugarcane byproduct) under HTS 3101.00.00.00 chemically treated via fermentation/dilution. Boosts compost decomposition rates.
Soybean Meal Organic Fertilizer
Expeller-pressed soybean meal delivers 7-2-1 NPK plus amino acids for protein-hungry crops. Vegetable origin under HTS 3101.00.00.00 mechanically extracted without chemical solvents. Preferred for organic certification programs.
Leather Tankage Fertilizer
Leather tankage from chrome-tanned leather scraps hydrolyzed into 10% nitrogen fertilizer. Animal-derived under HTS 3101.00.00.00 through alkaline hydrolysis processing. Chromium levels safe for agricultural use.
Guano Seabird Fertilizer
Seabird guano accumulated on Pacific islands offers high-nitrogen (10-12-3) complete organic fertilizer. Animal (bird droppings) product under HTS 3101.00.00.00 naturally aged/chemically altered through mineralization. Rare premium product for heirloom tomatoes.
