Quality Grades of Daily-use Ceramics: How to Identify and Understand Ceramic Product Standards
When sourcing daily-use ceramic tableware, understanding the quality grades is essential for importers, distributors, and brand owners. At STORIWARE, we believe in transparent standards and long-term cooperation. This article introduces how ceramic products are classified and what you should expect from each grade.
Main Quality Grades of Ceramic Tableware
In the daily-use ceramics industry, products are generally divided into the following quality levels:
1. First Grade (Grade A / Premium Quality)
Also known as "Export Grade", this is the highest quality level.
1-1, Smooth surface with no visible defects
1-2, Uniform glaze, consistent color
1-3, No pinholes, cracks, dark spots, or glaze skips
1-4, Passes food safety and lead/cadmium release tests
1-5, Suitable for direct retail, supermarkets, or branding use
Usage: Export to developed markets (EU, US, Japan), brand customization, retail sales
2. Second Grade (Grade B / Commercial Quality)
Acceptable for general wholesale and price-sensitive markets.
2-1, Minor visual defects allowed (e.g. small pinholes, slight color shade variation)
2-2, No structural damage or sharp edges
2-3, May have slight deformation or glaze unevenness, but not affecting usability
2-4, Safe for food contact
Usage: Discount stores, supermarkets, restaurant supply, promotional use
3. Third Grade (Grade C / Factory Seconds)
Lower quality, mainly for non-retail usage or highly price-focused markets.
3-1, Visible defects like dark spots, glaze skips, heavy deformation
3-2, Rough surface or under-glazed areas
3-3, Often sold as clearance or bulk factory stock
Usage: Local markets, non-food purposes, decoration, or secondary use

Bottom polish
Cracks or chips
Printing/Decal
Sound test
Inspection Focus
Smoothness, pinholes, particles
Roundness, height, flatness
Shade uniformity across batches
Smooth base without burrs
None allowed in first-grade products
Position accuracy, color fidelity
Clean “ring” when lightly tapped
Why Does This Matter?
