HS code for Small bag fertilizer: 3105.10
Fertilizers, mineral or chemical, in tablets or similar forms or in packages of a gross weight not exceeding 10kg.
Classification of small bag fertilizer under HS 3105.10
Classification under HS code 3105.10 is determined primarily by the physical presentation and weight of the fertilizer product rather than its specific chemical composition. This subheading covers mineral or chemical fertilizers that are either presented in tablets or similar forms, or in packages with a gross weight not exceeding 10 kilograms. The Harmonized System prioritizes the retail-ready nature of these goods, grouping various types of fertilizers—whether nitrogenous, phosphatic, or potassic—under this single code when they meet the weight threshold. This ensures that consumer-grade garden fertilizers and specialized agricultural inputs in small-scale packaging are treated uniformly for customs purposes, regardless of whether they are single-nutrient or multi-nutrient compounds. The logic behind this classification is to distinguish between industrial-scale agricultural commodities and retail-ready products intended for home gardening or small-scale horticultural use. When a fertilizer is packaged for retail sale in a bag weighing 10kg or less, the specific chemical subheadings in 3102, 3103, and 3104 are bypassed in favor of this more specific packaging-based classification. This rule applies even if the fertilizer is a pure chemical compound that would otherwise be classified elsewhere in Chapter 31.

Codes often confused with 3105.10
Common mistake. The most frequent error involves classifying these products based on their chemical content under headings 3102 (nitrogenous), 3103 (phosphatic), or 3104 (potassic). While those headings cover bulk fertilizers, Note 1 to Chapter 31 mandates that any fertilizer meeting the weight or form criteria of 3105.10 must be classified there first. Additionally, 3105.20 through 3105.90 are often used incorrectly for small packages; however, the 10kg limit in 3105.10 takes precedence over the specific chemical mixtures described in the subsequent subheadings. Another confusion arises with organic fertilizers; if the product is purely animal or vegetable-based without chemical fortification, it may fall under 3101 unless it is in tablet form.

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).
