HS Code for Collodion

Collodion is classified under HS code 3912.20, which specifically covers cellulose nitrates, including collodions, in primary forms. This classification is determined by General Interpretative Rule (GRI) 1 and 6. Chapter 39 of the Harmonized System governs plastics and their chemical derivatives. According to Note 6 to Chapter 39, the term \"primary forms\" includes liquids and pastes, such as solutions consisting of nitrocellulose dissolved in a mixture of ether and alcohol. Because collodion is a solution of cellulose nitrate, it is explicitly named in the subheading 3912.20. The classification remains here as long as the product is not put up for retail sale as a medicament or incorporated into a finished medical dressing. The chemical identity of the cellulose nitrate polymer is the primary factor for this heading, regardless of the solvent used, provided the solvent does not exceed 50% of the weight of the solution unless it is specifically for use as a plastic.

Products Included

• Flexible collodion
• Non-flexible (USP) collodion
• Nitrocellulose solutions in ether-alcohol mixtures
• Salicylic acid collodion (if not for retail medical sale)

Common Misclassification

Collodion is frequently misclassified under HS code 3005.10, which covers adhesive dressings and other articles having an adhesive layer. This occurs when the collodion is intended for medical use; however, unless it is impregnated with pharmaceutical substances and packaged for retail sale, it remains in Chapter 39. Another common error is HS code 3208.90, which covers paints and varnishes based on synthetic polymers. While collodion can form a film, it is chemically distinct as a cellulose derivative and is specifically provided for in heading 3912.

FAQ

What is the HS code for Collodion?

The HS code for Collodion is 3912.20, which falls under the category of cellulose nitrates in primary forms.

Is collodion classified as a medicament?

Generally, no. Unless it is specifically prepared and packaged for retail sale with therapeutic properties, it is classified as a chemical derivative of cellulose in Chapter 39 rather than Chapter 30.
