2,5-Dihydroxybenzenesulfonic acid potassium salt from Mexico
This is a specific sulfonated derivative of dihydroxybenzene (resorcinol) in the form of its potassium salt, explicitly listed under HTS 2908.99.0300. It features only sulfo groups attached to the phenolic structure, qualifying it for this chapter's heading for halogenated, sulfonated, nitrated or nitrosated derivatives of phenols. Used primarily as an intermediate in dye synthesis and chemical manufacturing.

Import Tips
• Provide detailed chemical analysis certificates confirming identity and purity as per chapter note (a) for separate chemically defined compounds
• Verify the product contains only sulfo groups without halogenation to avoid reclassification under other 2908 subheadings
• Include safety data sheets (SDS) documenting stabilizer use if present, per chapter note (f), to prevent customs delays
