HS Code for Gunpowder

Gunpowder is classified under HS code 3601.00 as a propellant powder. This classification is based on the product's function as a low explosive designed to burn at a controlled rate to produce gas pressure for propelling projectiles. Chapter 36 of the Harmonized System covers explosives, pyrotechnics, and certain combustible preparations. Heading 3601 is specifically reserved for propellant powders, which are distinct from prepared explosives of heading 36.02. Gunpowder, traditionally known as black powder, consists of an intimate mixture of potassium nitrate or sodium nitrate, charcoal, and sulfur. Modern smokeless powders, which are also classified here, are typically based on nitrocellulose (single-base) or a combination of nitrocellulose and nitroglycerin (double-base). The classification is determined by the explosive's intended use as a propellant rather than its chemical composition alone, provided it meets the definition of a propellant powder as outlined in the Explanatory Notes to Chapter 36.

Products Included

• Black powder (traditional gunpowder)
• Smokeless powder
• Nitrocellulose-based propellants
• Double-base propellant powders
• Propellant powders for small arms and artillery

Common Misclassification

Gunpowder is often misclassified under HS code 3602.00, which is reserved for prepared explosives like dynamite, TNT, or plastic explosives. The distinction lies in the rate of reaction; 3601.00 is for propellants (deflagration), while 3602.00 is for high explosives (detonation). It may also be confused with safety fuses or detonating fuses under 3603.00, which are finished articles used to ignite explosives rather than the explosive material itself. Additionally, fireworks and pyrotechnic articles are classified under 3604.10, even if they contain gunpowder as a lifting charge, because the finished article's primary function is entertainment.

FAQ

What is the HS code for gunpowder?

The HS code for gunpowder is 3601.00. This code applies to both traditional black powder and modern smokeless propellant powders used in firearms, artillery, and rocket motors.

Is nitrocellulose classified under this code?

Pure nitrocellulose is typically classified in Chapter 39 as a polymer. However, when it is prepared as a propellant powder (smokeless powder) by adding stabilizers or other agents, it is classified under 3601.00.
