HS Code 2811.19 – Inorganic acids; other than hydrogen fluoride
HS code 2811.19 is the 6-digit subheading for inorganic acids, other than hydrogen fluoride. It is used for sulfuric acid, nitric acid, phosphoric acid, hydrochloric acid and perchloric acid.
What HS 2811.19 covers
This code encompasses a diverse range of inorganic acids, excluding hydrogen fluoride, that are fundamental to numerous industrial processes globally. These acids, such as nitric acid, sulfuric acid, and phosphoric acid, are crucial raw materials for manufacturing fertilizers, detergents, plastics, pharmaceuticals, and various chemicals. Major importers and exporters include countries with robust chemical industries and significant agricultural sectors, like China, the United States, Germany, and India. Trade in these acids is often driven by demand from downstream industries, and their classification is vital for customs duties, safety regulations, and environmental controls. Due to their corrosive nature, international trade involves stringent packaging, labeling, and transportation protocols, making logistics a critical component of their supply chain. Understanding the specific concentration and purity is also key for trade valuation and application.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. 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).
