HS Code 2510.10 – Natural calcium phosphates, natural aluminium calcium phosphates and phosphatic chalk; unground

HS code 2510.10 is the 6-digit subheading for natural calcium phosphates, natural aluminium calcium phosphates and phosphatic chalk, unground. It is used for phosphate rock, apatite, phosphorite, guano (fossilized) and aluminium calcium phosphate ore.

What HS 2510.10 covers

This code covers raw, unground forms of natural phosphates, primarily used as a fundamental input for the fertilizer industry. These minerals are crucial for agricultural productivity, supplying phosphorus, an essential plant nutrient. Major importers are countries with large agricultural sectors and limited domestic phosphate reserves, such as India, Brazil, and various European nations. Exporters typically include countries rich in phosphate deposits like Morocco, China, and the United States. Key things to know include the importance of its P2O5 content for quality assessment, its role in producing phosphoric acid and superphosphates, and the environmental considerations related to mining and processing. The global trade in unground phosphate rock is a significant indicator of agricultural demand and the health of the fertilizer market, often influenced by commodity prices and geopolitical factors affecting supply chains. Its raw state means further processing is always required before end-use.

Codes often confused with 2510.10

Common mistake. This code might be confused with 251020 (ground phosphates) if the material has undergone any grinding, or with 3103 (mineral or chemical fertilizers, phosphatic) if it's already processed into a fertilizer product.

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).
