HS Code 3105.10 – Fertilizers, mineral or chemical; in tablets or similar forms or in packages of a gross weight not exceeding 10kg

HS code 3105.10 is the 6-digit subheading for fertilizers, mineral or chemical, in tablets or similar forms or in packages of a gross weight not exceeding 10kg. It is used for garden fertilizer tablets, slow-release fertilizer pellets, potted plant food sticks, lawn fertilizer granules (small packs) and hydroponic nutrient tablets.

What HS 3105.10 covers

This HS code encompasses mineral or chemical fertilizers presented in tablets, similar forms, or in packages with a gross weight not exceeding 10 kg. This category primarily targets the retail market, including home gardening, small-scale horticulture, and specialized applications where precise dosing and ease of handling are paramount. The smaller packaging often implies a higher unit value due to processing, branding, and distribution costs. Importers and exporters in this segment typically include specialty chemical distributors, garden supply retailers, and companies catering to niche agricultural markets. The trade in these products is influenced by consumer gardening trends, urban farming growth, and demand for convenient, ready-to-use fertilizer solutions. Compliance with labeling regulations and consumer safety standards is particularly important for these retail-oriented products.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
