Last updated: August 2026 dataMined from natural caliche deposits in the Atacama Desert, Chilean sodium nitrate (also called Chile saltpeter) has been a commercial nitrogen source for over a century and remains the dominant natural-origin product in this heading. Classified under 3102500000, Chile leads US imports by a wide margin, with Germany and Mexico also supplying the market. Synthetic sodium nitrate produced as an industrial byproduct competes with the natural mined product; importers may need to document origin and production method to satisfy buyer specifications or organic-certification requirements, as only naturally mined sodium nitrate is approved for use in certified organic production.

No. USDA National Organic Program (NOP) rules permit only naturally mined sodium nitrate, and even that is subject to use restrictions. Synthetic sodium nitrate is prohibited in certified organic production. Importers supplying the organic market must obtain documentation from the supplier confirming the product is naturally mined and not synthetically derived.
A certificate of origin, a mine-source declaration from the Chilean producer, and a certificate of analysis showing trace mineral profiles consistent with caliche ore are the standard documents. Buyers in the organic sector may also require third-party certification. CBP may request these documents if the declared origin or production method is unclear.
