Pottery porcelain

The primary difference lies in the firing temperature and clay composition. Pottery (earthenware/stoneware) is fired at lower temperatures (1,000°C–1,200°C), resulting in a porous structure that usually requires glazing for waterproofing. Porcelain is fired at much higher temperatures (above 1,300°C) and contains kaolin clay, which creates a vitrified, translucent, and non-porous finish. For commercial use, porcelain is generally preferred for its superior durability, chip resistance, and thermal shock stability.

Compliance is critical due to food safety risks. Buyers must ensure products meet FDA (USA) or Regulation (EC) No 1935/2004 (EU) standards regarding leachable lead and cadmium. For specific markets, look for ISO 6486-1 certification. If sourcing for the California market, Proposition 65 compliance is mandatory. Always request Third-Party Lab Test Reports (SGS, TUV, or Intertek) to verify that glazes are food-safe and BPA-free.

Focus on Edge Chip Resistance and Glaze Hardness. High-quality commercial porcelain should have a reinforced rim to prevent breakage during heavy use. The glaze should be scratch-resistant (tested via the Mohs scale) to withstand metal cutlery marks. Additionally, verify dishwasher and microwave safety by checking the water absorption rate; professional-grade porcelain should have a water absorption rate of less than 0.5%.

Suppliers on Made-in-China.com typically offer OEM/ODM services including custom logo application (under-glaze or over-glaze decals), bespoke color matching (Pantone), and custom mold development. For high-end retail, consider reactive glazes, which provide a unique, handcrafted look while maintaining industrial durability. Note that custom molds usually involve a tooling fee and a higher Minimum Order Quantity (MOQ).

Ceramics are fragile, so packaging specifications are paramount. Insist on 5-layer corrugated export cartons with individual bubble wrap or EPE foam inserts. For bulk shipments, products must be palletized with plastic wrap and corner protectors. It is highly recommended to conduct a ISTA 1A Drop Test before the goods leave the factory to ensure the packaging can withstand the rigors of cross-border transit.

Prices in the ceramic industry are heavily influenced by energy costs (kiln firing) and raw material purity. When negotiating on Made-in-China.com, leverage volume-based pricing; a 20GP container load usually yields a 15-25% discount compared to LCL (Less than Container Load) orders. If you are a startup, look for suppliers with 'Ready-to-Ship' stock to enjoy lower MOQs, though customization will be limited.

Always use Secured Payment services provided by the platform to protect your funds until shipping documents are verified. Before paying the final 70% balance, hire a third-party inspection agency to perform a Pre-Shipment Inspection (PSI). They should check for warping, pinholes in the glaze, and color consistency across the batch. Never wire large sums to personal bank accounts; ensure the account name matches the Business License of the supplier.

Buyers must be aware of Anti-Dumping Duties (ADD). For example, the EU and certain other regions have previously imposed high duties on specific Chinese ceramic tableware to protect local industries. Check your local Harmonized System (HS) Code (typically Chapter 69) and consult with a customs broker to determine the Total Landed Cost, including any retaliatory tariffs or special duties applicable to your specific country.
