📦 I. Product Definition & Classification: What Exactly Is a "Casings Surface Treatment Agent"?

A Casings Surface Treatment Agent refers to polishes, creams, scouring pastes, powders, and similar preparations used for treating footwear, furniture, floors, coachwork, glass, or metal casings — including protective or decorative coatings applied to the surface of casings (e.g., automotive, industrial, or appliance casings).

⚠️ Key Clarification:
- This category excludes waxes (which fall under HS 3404).
- It includes impregnated, coated, or covered materials such as paper, felt, nonwovens, cellular plastics/rubber — as long as they contain surface treatment agents.
- Not for general industrial cleaning; only for surface finishing, polishing, or protection.
