paraffin wax

Selecting the correct grade depends primarily on the oil content and melting point. For high-end candle making, Fully Refined Paraffin Wax (oil content <0.5%) is preferred as it provides a clean burn and excellent scent throw. For industrial rubber or match production, Semi-Refined Paraffin Wax (oil content 1.5% - 2.0%) is more economically feasible. If the application involves food packaging or cosmetics, you must ensure the product is Food Grade and complies with FDA or REACH standards to guarantee safety and non-toxicity.

Buyers should prioritize three main metrics: Melting Point, Oil Content, and Color (Saybolt scale). A melting point between 58°C and 60°C is standard for most climates, but for tropical regions, a higher melting point (62°C+) is necessary to prevent deformation during transit. The Saybolt color value should ideally be +28 to +30 for fully refined wax, indicating high purity and a snow-white appearance. Always request a Certificate of Analysis (COA) from the supplier to verify these parameters against your specific requirements.

Paraffin wax must meet specific safety benchmarks depending on the target market. For the European market, REACH certification is mandatory to ensure chemical safety. For products intended for skin contact (like paraffin baths) or food-related uses, ISO 22000 or FDA compliance is critical. Additionally, ensure the supplier provides a Material Safety Data Sheet (MSDS), which is vital for customs clearance and safe handling during the logistics process.

Consistency is key in chemical sourcing. Evaluate suppliers based on their production capacity and raw material source (crude oil vs. synthetic). Look for manufacturers with ISO 9001 certification, which indicates a standardized quality management system. It is highly recommended to order a 5kg-10kg sample for lab testing before committing to a full container load (FCL) to check for odor, smoke levels, and shrinkage rates.

The biggest risk is temperature-induced melting or clumping during sea freight, especially when crossing the equator. To mitigate this, use Reefer Containers for high-value refined wax or ensure the cargo is stowed 'Below Deck' and 'Away from Heat Sources'. Additionally, ensure the packaging (usually 25kg cartons or woven bags) is robust enough to prevent leakage or contamination from other goods in the vessel.

Paraffin wax prices are closely tied to global crude oil fluctuations. It is wise to negotiate a formula-based pricing model for long-term contracts. For new buyers on Made-in-China.com, utilizing Secured Trading Services is recommended to protect the deposit. Aim for a 30% deposit and 70% balance against the Bill of Lading (B/L) to balance risk between the buyer and the seller.

A common 'trap' is suppliers substituting Fully Refined wax with Semi-Refined wax to lower costs. This can only be detected through oil content laboratory testing. To prevent this, hire a third-party inspection agency like SGS or Intertek to perform a Pre-Shipment Inspection (PSI) at the factory to verify the batch matches the agreed-upon specifications.

Verify the HS Code (typically 27122000) with your local customs broker to determine the exact import duty and VAT. Some countries may have anti-dumping duties on paraffin products from specific regions. Ensure all documents, including the Commercial Invoice, Packing List, COA, and Certificate of Origin, are perfectly aligned to avoid costly port storage fees due to clearance delays.
