HS Code for Silver nitrate

Silver nitrate is classified under HS code 2843.21. This code is found within Chapter 28, which covers inorganic chemicals and compounds of precious metals. Heading 2843 is dedicated to precious metals in colloidal form, amalgams, and both inorganic and organic compounds of precious metals. Silver nitrate (AgNO3) is a specific chemical compound of silver and is explicitly identified in subheading 21. The classification applies to the chemical in its pure form or in aqueous solutions. It is used extensively in photography, medical applications, and industrial silver plating, but its classification remains fixed in Chapter 28 as long as it is a separate chemically defined compound.

Products Included

• Reagent grade silver nitrate crystals
• Industrial grade silver nitrate
• Aqueous silver nitrate solutions
• Silver nitrate for mirror manufacturing
• High-purity silver nitrate for laboratory use

Common Misclassification

Silver nitrate is often confused with 2843.29, which is the category for "other" silver compounds like silver oxide or silver chloride. It can also be misclassified under 3004 if it is put up in measured doses for medical use, such as cauterizing sticks. Additionally, if silver nitrate is part of a prepared photographic chemical mixture (like a developer or fixer), it should be classified under 3707 instead of 2843.21.

FAQ

What is the HS code for silver nitrate?
