Source Fully Refined Paraffin Wax for Candle, PVC, and Packaging

Strategic Sourcing Guide for Fully Refined Paraffin Wax

Understanding Product Classification and Core Attributes

When sourcing fully refined paraffin wax, buyers must first establish a precise understanding of the product's fundamental classification and physical characteristics. The core material is identified as a paraffin wax, specifically categorized under industrial-grade specifications. This distinction is critical because the degree of refinement directly influences the product's purity, color stability, and suitability for sensitive applications such as food packaging or candle manufacturing. The product is consistently observed as a solid substance, typically presenting in a white color profile. This whiteness is not merely aesthetic; it serves as a primary indicator of the refining process quality, often correlating with low oil content and high light stability.

The physical form of the wax varies depending on the specific production batch and intended market segment. Buyers may encounter the material in granular, slab, or lump forms. The "White Lump" and "Granular & Slab" descriptions indicate that the wax can be supplied in block-like structures or loose granules, which affects handling and storage logistics. The chemical composition is defined by its chief constituents as wax, with a specific mention of low molecular weight polyethylene in certain contexts, though the primary identity remains paraffin. The raw material source is often traced back to specific petroleum refineries, such as Kunlun Oil or Petrochina Fushun, indicating a heavy reliance on petrochemical feedstocks.

One of the most defining technical parameters for fully refined paraffin wax is the softening point. In the observed market data, this value ranges between 100 and 105 degrees Celsius for specific high-performance grades, while other common industrial grades are frequently cited in the 58/60 or 60/62 degree Celsius ranges. This variation dictates the thermal stability of the final product. A higher softening point, such as the 100-105 range, suggests a formulation designed for high-temperature resistance, making it suitable for applications requiring durability under heat stress. Conversely, the 60-62 degree Celsius range is standard for general-purpose applications like candle manufacturing and basic rubber tire processing. Buyers must verify the specific softening point required for their end-use application, as using a wax with an incorrect melting range can compromise product integrity.

Technical Specifications and Performance Metrics

The technical specification sheet for fully refined paraffin wax is a complex document that buyers must scrutinize to ensure compatibility with their manufacturing processes. Several key metrics define the quality and performance of the wax. Density is a critical physical property, typically observed within the range of 0.92 to 0.95 grams per cubic centimeter. This density range is consistent with high-quality paraffin and helps in calculating volumetric requirements for shipping and storage.

Viscosity is another essential parameter, with observed values falling between 5 and 10. This range indicates the flow characteristics of the wax when melted, which is vital for injection molding, coating, or impregnation processes. If the viscosity is too high, the wax may not flow evenly into molds or coatings; if too low, it may lack the necessary structural integrity. The needle penetration test, conducted at 25 degrees Celsius, provides insight into the hardness of the wax. The data indicates a range of 17 to 23 (1/10mm) for certain grades, with a maximum limit of 19 for others. This metric is particularly important for candle manufacturing and modeling waxes, where hardness determines the burn rate and structural stability of the finished product.

Oil content is perhaps the most significant purity indicator for refined paraffin. The supply data consistently highlights a maximum oil content of 0.5% by weight. This low oil content is a hallmark of the "fully refined" designation. High oil content can lead to issues such as surface bloom, poor adhesion, and reduced light stability. The light stability is measured on a Saybolt scale, with a maximum value of 4 observed in the data, while color is also noted as +30 on the Saybolt scale. These values suggest a high degree of whiteness and resistance to discoloration under light exposure, which is crucial for applications in food packaging and cosmetic candles.

The chemical identity is further confirmed by the CAS number 9002-88-4, which is the standard registry for paraffin wax. The HS code 2712200000 is used for customs classification, indicating the product falls under the category of mineral waxes. Buyers should ensure that the supplier provides documentation matching these identifiers to avoid regulatory issues during import and export. The refinement process is described as "fully refined," implying that the wax has undergone extensive treatment to remove impurities, aromatics, and unsaturated hydrocarbons. This level of refinement is necessary for applications requiring high purity, such as poultry depilation or food-grade packaging.

Compliance, Certification, and Regulatory Standards

Navigating the compliance landscape for fully refined paraffin wax requires a careful verification of certifications and adherence to international standards. The primary standard observed in the market data is "Industrial Grade," which serves as a baseline for general manufacturing applications. However, for specialized uses, buyers must look for additional certifications. The data explicitly mentions SGS certification, a globally recognized third-party inspection and verification company. The presence of SGS certification indicates that the product has undergone independent testing for quality and safety, providing a layer of assurance for buyers.

While background information mentions ISO9001, REACH, and RoHS, these should be treated as potential attributes rather than guaranteed facts for every supplier. Buyers must explicitly request proof of these certifications if their end markets require them. For instance, REACH compliance is essential for selling products in the European Union, ensuring that the wax does not contain restricted substances. RoHS compliance is critical for electronics-related applications, although less common for standard paraffin wax. The absence of these specific certifications in the primary data means that buyers cannot assume they are present; they must be verified on a case-by-case basis.

The production methods are described as "Transfer Legal," suggesting adherence to regulatory frameworks regarding the transfer of goods and compliance with local laws. The place of origin is consistently listed as China, specifically regions like Liaoning (Mainland) and Fushun. This geographic concentration implies a mature supply chain but also necessitates due diligence regarding export regulations and trade barriers. Buyers should verify that the supplier can provide a Certificate of Origin and any necessary export licenses.

Furthermore, the packaging standards play a role in compliance. The data mentions various packaging formats, including 25kg bags, 50kg woven bags, and cartons. The standard "25Bag/50KG Carton" suggests a specific palletization or bulk shipping protocol. Ensuring that the packaging meets international shipping standards is vital to prevent contamination or damage during transit, which could compromise the product's quality and regulatory status.

Cost Drivers and Pricing Dynamics

The pricing of fully refined paraffin wax is influenced by a complex interplay of raw material costs, refining complexity, and market demand. The observed price range in the market spans from 1 to 1300 USD, a wide variance that reflects differences in product grade, quantity, and packaging. The lower end of this spectrum likely corresponds to bulk industrial grades with minimal customization, while the higher end may reflect specialized, fully refined grades with specific certifications or smaller, more convenient packaging.

Volume is a primary cost driver. The Minimum Order Quantity (MOQ) ranges from 0 to 500 units, indicating flexibility in purchasing. Suppliers offering lower MOQs may charge a premium per unit to cover setup and handling costs. Conversely, larger orders typically benefit from economies of scale, reducing the unit price. The packaging format also impacts cost; for example, 25kg bags or 50kg woven bags are standard, but specialized packaging like "One Block Weigh 5kg" or "25kg/Carton" may incur additional costs due to the labor and materials involved in custom packaging.

The raw material source, such as Kunlun Oil or Petrochina Fushun, can influence pricing. Products sourced from major state-owned refineries may command a premium due to perceived quality consistency and reliability. Additionally, the degree of refinement is a significant cost factor. Fully refined wax requires more processing steps than semi-refined or crude wax, driving up the production cost. The specific softening point and oil content requirements also play a role; tighter tolerances on oil content (e.g., 0.5% max) and specific softening points (e.g., 100-105°C) may require more precise control during manufacturing, adding to the cost.

Currency fluctuations and global oil prices are external factors that can cause price volatility. Since paraffin wax is a byproduct of petroleum refining, its price is inherently linked to crude oil markets. Buyers should monitor these trends and consider long-term contracts to lock in prices if stability is a priority. The customization options available, such as specific packaging or blending, also add to the cost. Buyers must balance the need for customization against the budget constraints, ensuring that the added value justifies the extra expense.
