Import Tips
• Document the slip's composition and firing temperature to distinguish from general clays in Chapter 25
• Ensure invoices specify 'engobes for glass industry' to align with heading description
• Test for dispersion in nonaqueous media; if paint-like, it may be excluded per chapter notes to 3203-3206
