HS Code for Amino resin

HS code 390939 classifies amino-resins in primary forms, specifically those not elsewhere specified or included within heading 3909, and excluding poly(methylene phenyl isocyanate) (Crude MDI, polymeric MDI). This classification is determined by the chemical nature of the polymer, its physical state, and specific exclusions. Amino-resins are thermosetting polymers derived from the reaction of formaldehyde with compounds containing amino groups, such as urea or melamine. "Primary forms" refers to the basic shapes in which plastics are typically supplied, including liquids, pastes, powders, granules, flakes, and similar bulk forms, ready for further processing. The "n.e.c." (not elsewhere specified or included) clause ensures that this code captures a broad range of amino-resins not covered by more specific subheadings.

Products Included

• Urea-formaldehyde resins in liquid or powder form.
• Melamine-formaldehyde resins in granules or flakes.
• Poly(urea-formaldehyde) resins in primary forms.
• Poly(melamine-formaldehyde) resins in primary forms.
• Other amino-resins, such as benzoguanamine-formaldehyde resins, in primary forms, not specifically classified elsewhere.

Common Misclassification

Common misclassification can occur with other types of resins within Chapter 39, such as phenolic resins (HS code 390940) or polyurethanes (HS code 390950), which have distinct chemical structures. It is crucial to correctly identify the specific polymer type. Another frequent error is classifying amino resins that are no longer in primary forms, such as sheets, films, or other semi-manufactures, which would typically fall under HS codes like 3920 or 3921. Furthermore, the specific exclusion of poly(methylene phenyl isocyanate) (Crude MDI, polymeric MDI) means these products, despite containing amino groups, are classified elsewhere, typically under 390950 as polyurethanes or their precursors.

FAQ

What is the HS code for Amino resin?

The HS code for amino resins in primary forms, not elsewhere specified in heading 3909 and excluding poly(methylene phenyl isocyanate), is 390939. This code covers various amino-formaldehyde resins in their basic, unprocessed states.

What constitutes 'primary forms' for resins in HS classification?

"Primary forms" for plastics, including resins, generally refers to the initial shapes in which they are supplied for further processing. These include liquids, pastes, solutions, dispersions, emulsions, powders, granules, flakes, lumps, and similar bulk forms. These forms are typically not yet shaped into finished articles or semi-manufactures like sheets or films.
