HS code for Amino resin: 3909.39
Amino-resins, n.e.c. in heading no. 3909, in primary forms, other than poly(methylene phenyl isocyanate) (Crude MDI, polymeric MDI).
Classification of amino resin under HS 3909.39
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.
- Covers
- Urea-formaldehyde resins in liquid or powder form.
- Melamine-formaldehyde resins in granules or flakes.

- Poly(melamine-formaldehyde) resins in primary forms.
- Other amino-resins, such as benzoguanamine-formaldehyde resins, in primary forms, not specifically classified elsewhere.
- Also under 3909.39
- Arclin UF Resins
- Hexion Melamine Resins
- Georgia-Pacific UF Resins
- Sumitomo Bakelite Melamine Molding Compounds
Codes often confused with 3909.39
Common mistake. 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.
Top exporters and importers of HS 390939 (the code used for amino resin), 2025
In 2025, the largest exporter of HS 390939 (the code used for amino resin) in UN Comtrade data was Germany, with 16% of world exports; the largest importer in UN Comtrade data was India, with 9.6% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).

Questions about amino resin
What is the HS code for Amino resin?
The HS code for Amino resin is 390939 (Amino-resins; n.e.c. in heading no. 3909, in primary forms, other than poly(methylene phenyl isocyanate) (Crude MDI, polymeric MDI)). 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.
How do I classify Amino resin for customs?
Amino resin is classified under HS code 390939 — Amino-resins; n.e.c. in heading no. 3909, in primary forms, other than poly(methylene phenyl isocyanate) (Crude MDI, polymeric MDI). This is a 6-digit subheading level code.
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.
Which countries are the top exporters of amino resin (HS 390939)?
In 2025, the top exporters of HS 390939 (the code used for amino resin) in UN Comtrade data were Germany ($67M, 16% of world exports), Hungary ($55M) and Poland ($53M). World exports came to about $414M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of amino resin (HS 390939)?
