Custard powder

High-quality custard powder primarily consists of cornstarch (maize starch), flavorings (usually vanilla), and food-grade colorants (like Annatto or Tartrazine). B2B buyers should verify the starch purity level, ensuring it is free from moisture clumps. The powder should have a fine particle size (mesh) to ensure a smooth, lump-free texture when reconstituted. Always request a Certificate of Analysis (COA) to confirm the absence of heavy metals and microbial contaminants.

Compliance is critical in food sourcing. Suppliers must hold HACCP (Hazard Analysis and Critical Control Points) and ISO 22000 (Food Safety Management) certifications. For specific markets, look for FDA registration (USA), EFSA compliance (EU), or Halal/Kosher certifications if targeting religious consumer segments. Ensure the packaging lists all allergens, particularly if the facility processes milk, soy, or gluten.

Request samples to test the viscosity and thickening power. A professional evaluation involves measuring the gelatinization temperature and the stability of the custard after cooling (checking for syneresis or water separation). The color should remain vibrant and consistent after cooking, and the flavor profile must be heat-stable, meaning the vanilla aroma should not dissipate during the boiling process.

Custard powder is highly sensitive to moisture and odors. For bulk B2B orders, ensure the product is packed in multi-layer moisture-proof bags (PE/Aluminium/PET) or hermetically sealed tin cans. The standard shelf life should be 18 to 24 months. For shipping, use palleted loads with shrink-wrap to prevent puncture damage and contamination during transit.

The primary risks include adulteration (filling with cheaper starches) and ingredient non-compliance with local food laws. To mitigate this, use third-party inspection services (like SGS or Intertek) to conduct pre-shipment sampling. Ensure your contract specifies that the batch number on the COA must match the physical cargo.

Pricing is heavily influenced by the global corn starch market price. Negotiate based on volume tiers; typically, a 20ft container load (FCL) can reduce unit costs by 15-20% compared to LCL. For new brands, look for suppliers on Made-in-China.com who offer OEM/Private Label services with manageable MOQs (e.g., 500kg - 1 ton) to test market response.

Custard powder is classified under HS Code 1901.90. Ensure all Health Certificates and Phytosanitary Certificates are prepared by the exporter. Choose dry-van containers that are clean and free of strong odors (like chemicals or rubber), as starch easily absorbs surrounding scents. For long-haul sea freight, use desiccant bags inside the container to prevent 'container rain' caused by temperature fluctuations.

Always prioritize Verified Suppliers on professional platforms like Made-in-China.com. Utilize Secured Payment services or Letter of Credit (L/C) for large transactions to ensure funds are only released upon proof of shipment. Avoid direct wire transfers to private accounts; always pay to the registered corporate bank account of the manufacturing entity.
