HS-6 · Subheading
390931
Amino-resins; n.e.c. in heading no. 3909, in primary forms, poly(methylene phenyl isocyanate) (Crude MDI, polymeric MDI)
Heading 3909 — Amino-resins, phenolic resins and polyurethanes, in primary forms
Chapter 39: Plastics and articles thereof
Plain-language overview
Use HS-6 390931 when importing or exporting amino-resins, specifically poly(methylene phenyl isocyanate) in primary forms, such as crude MDI or polymeric MDI. These materials are crucial in producing flexible and rigid foams, coatings, and adhesives.
This code is distinct from HS-6 390932, which covers other types of amino-resins. While both fall under the same heading of amino-resins, 390931 specifically targets poly(methylene phenyl isocyanate), a key ingredient in polyurethane manufacturing.
When shipping products classified under this code, ensure that they are in their primary forms, as the classification does not apply to finished goods or mixtures. For example, a shipment of crude MDI in bulk containers would be correctly classified under this HS-6.
If you're dealing with formulations that include other resins or additives, you may need to consider different HS codes. For instance, if your product contains both crude MDI and other resins, you might need to classify it differently based on its primary component.

Questions & answers
For orientation only—the binding text is your national tariff and the WCO nomenclature your country uses.
- What products fall under HS-6 390931?
- HS-6 390931 covers poly(methylene phenyl isocyanate) in its primary forms, including crude MDI and polymeric MDI, used primarily in polyurethane production.
- Can I classify finished polyurethane products under this HS code?
- No, HS-6 390931 is specifically for amino-resins in primary forms. Finished products made from these resins would require a different classification.
- What is the difference between crude MDI and polymeric MDI?
- Crude MDI is the unrefined form of the resin, while polymeric MDI refers to a processed version that is typically used in specific applications like rigid foam production.
- How do I ensure compliance when importing these materials?
- Make sure to provide accurate documentation and labeling that reflects the primary form of the amino-resins you are importing, as required by customs regulations.
- Are there any safety regulations for shipping crude MDI?
- Yes, crude MDI is classified as hazardous, so you must comply with safety regulations, including proper labeling, packaging, and transportation guidelines.
- What should I do if my product contains multiple resins?
- If your product contains multiple resins, classify it based on the primary component. If unsure, consult with a customs broker for proper classification.
- Is there a specific packaging requirement for poly(methylene phenyl isocyanate)?
- Yes, poly(methylene phenyl isocyanate) should be packaged in containers that comply with hazardous material regulations, ensuring safety during transport.
- Can I use this HS code for exports?
- Yes, HS-6 390931 can be used for exports as long as the product meets the definition of amino-resins in primary forms.
