Product classification
HS code for Complete fertilizer: 3105.20
Fertilizers, mineral or chemical, containing the three fertilizing elements nitrogen, phosphorus and potassium.
Classification of complete fertilizer under HS 3105.20
Complete fertilizers are classified under HS code 3105.20. In the context of the Harmonized System, a "complete" fertilizer is defined as a mineral or chemical fertilizer that contains all three primary fertilizing elements: nitrogen (N), phosphorus (P), and potassium (K). Chapter 31 covers fertilizers, and heading 3105 specifically addresses fertilizers containing two or three of the fertilizing elements. Subheading 3105.20 is the precise code for those containing all three. This classification is based on the chemical composition of the product rather than its physical form (liquid, powder, or pellet). According to Note 6 to Chapter 31, the term "other fertilizers" applies only to products of a kind used as fertilizers and containing, as an essential constituent, at least one of the fertilizing elements. For 3105.20, the presence of N, P, and K must be verifiable through chemical analysis. This ensures that ternary NPK complexes are grouped together for international trade and regulatory purposes.

Codes often confused with 3105.20
Common mistake. Complete fertilizers are often misclassified under HS code 3105.30 (diammonium phosphate) or 3105.40 (ammonium dihydrogen orthophosphate) if the importer focuses only on the nitrogen and phosphorus content and ignores the potassium. Another common error is using codes from 3102 (nitrogenous), 3103 (phosphatic), or 3104 (potassic) for a blended product. Those headings are strictly for fertilizers containing only one of the primary elements. If a fertilizer contains N, P, and K, it must be in 3105.20. Furthermore, organic fertilizers (animal or vegetable origin) are classified in 3101 and should not be confused with the mineral/chemical NPK fertilizers of 3105.20.

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).
