Classification: Prepared binders for foundry molds or cores; chemical products and preparations of the chemical or allied industries (including those consisting of mixtures of natural products), not elsewhere specified or included
Explanation: Mixtures consisting mainly of chemicals containing a phosphorus atom to which is bonded one methyl, ethyl, n-propyl or isopropyl group, but no other carbon atoms. Specifically, it refers to chemical mixtures mainly composed of compounds containing a phosphorus atom bonded to a methyl, ethyl, n-propyl, or isopropyl group, with no other carbon atoms present.

Examples of products that may fall under this classification:
- Phosphorus-based chemical binders used in foundry molds
- Chemical mixtures containing phosphorus with methyl or ethyl groups
- Industrial chemical preparations with specific phosphorus-based components
- Specialty chemical formulations used in casting processes
- Custom-made chemical mixtures for industrial applications
