Amino-resins, phenolic resins and polyurethanes, in primary forms
8 declarable lines
Heading 3909 covers amino-resins, phenolic resins and polyurethanes in primary forms. The heading is split first by resin family: urea and thiourea resins, melamine resins, other amino-resins, phenolic resins, and polyurethanes. Polyurethanes are split further into elastomeric, cements and other.
Products in this heading
- Urea-formaldehyde resin powder for molding or adhesives
- Thiourea resin in primary form
- Melamine-formaldehyde resin powder
- Crude MDI or polymeric MDI
- Phenolic resin for coatings or binders
- Polyurethane elastomer in primary form
- Polyurethane cement adhesive
- Other polyurethane resin in primary form
How to choose the right subheading
- Identify the resin family: amino-resin, phenolic resin or polyurethane.
- For amino-resins, decide between urea or thiourea resins, melamine resins and other amino-resins.
- For polyurethanes, decide between elastomeric, cements and other.
- Confirm the goods are in primary forms such as liquid, paste, powder, granules or irregular blocks, not finished shapes or articles.
- Use the specific 8-digit or 10-digit line that matches the product description.
