Food grade paraffin wax

Food grade paraffin must strictly adhere to international safety standards. You should verify that the product complies with FDA 21 CFR 172.886 (for direct food contact) or FDA 21 CFR 178.3710 (for indirect contact). In the EU, look for E905 compliance. The wax must be fully refined, meaning it has an oil content of less than 0.5%, ensuring it is odorless, tasteless, and non-toxic.

The melting point is a key functional attribute. For fruit coating (e.g., citrus or apples), a melting point between 52°C and 58°C is common to provide a flexible moisture barrier. For cheese waxing, a slightly higher range or a blend with microcrystalline wax is preferred for better adhesion. For food packaging/paper coating, a melting point of 58°C to 62°C ensures the coating remains stable under varying storage temperatures.

Beyond the melting point, you must check the Saybolt Color index, which should be +28 to +30 (indicating near-transparency). The Polycyclic Aromatic Hydrocarbons (PAHs) levels must be within legal limits to ensure the product is non-carcinogenic. Always request a Certificate of Analysis (COA) and a Material Safety Data Sheet (MSDS) to verify these chemical properties before shipment.

It is widely used as a release agent in professional baking to prevent dough from sticking to tins, as a protective coating for fruits and vegetables to extend shelf life, and in the production of gum base. It is also essential for waterproofing food-grade cardboard and lining beverage containers.

This is a major risk in chemical sourcing. To mitigate this, only source from manufacturers with ISO 22000 or HACCP certifications, which govern food safety management. Use Made-in-China.com's 'Audited Supplier' reports to verify the factory's production lines and ensure they have dedicated equipment for food-grade processing to avoid cross-contamination.

Paraffin wax is sensitive to temperature. For cross-border shipping, ensure the wax is packed in heavy-duty woven bags or cartons with inner plastic liners to prevent contamination. If shipping to tropical regions, consider refrigerated containers (reefers) or ensure the cargo is stowed 'below deck' away from heat sources to prevent the slabs from fusing together during transit.

Paraffin prices are closely tied to crude oil market fluctuations. It is wise to negotiate formula-based pricing for long-term contracts. For new buyers, start with a trial order of 1-5 tons to test quality. Suppliers on Made-in-China.com often offer significant discounts for 20ft container loads (approx. 20-21 tons) due to optimized shipping costs.

Always use Secured Trading services provided by the platform to ensure payment is only released after the Bill of Lading (B/L) is issued. For high-value orders, hire a third-party inspection agency (like SGS or Intertek) to perform a pre-shipment inspection to verify the melting point and purity at the loading port.
