These physical constants are critical for logistics planning, particularly regarding bulk density calculations for shipping, and for processing equipment design in manufacturing facilities. The drying loss specification is a key quality indicator, with observed limits set at ≤1.5%, ensuring the product maintains low moisture content which is essential for shelf stability.

The product is available in various models, including specific designations such as Z205 and Z206, though these codes often correlate with specific packaging configurations or purity tiers rather than fundamental chemical differences. Buyers should note that the material is classified under multiple resource categories, including natural preservatives, inorganic chemical preservatives, and organic chemical preservatives, reflecting its versatile classification in different regulatory frameworks. The primary composition is sodium benzoate, which functions as a bacteriostatic agent and antiseptic. It is distinct from benzoic acid, though they are chemically related, and the specific product listing confirms the composition as sodium benzoate for the primary preservative applications.

Regulatory Compliance and Certification Verification

Compliance is the cornerstone of sourcing food-grade chemicals. The supply chain for sodium benzoate must adhere to rigorous international standards to ensure safety for consumption in food, beverages, and skincare applications. The observed certification landscape includes ISO22000 and HACCP, which are vital for food safety management systems. Additionally, Kosher certification is frequently listed, indicating suitability for specific dietary markets.

The product standards referenced in the market data include USP (United States Pharmacopeia), BP (British Pharmacopoeia), EP (European Pharmacopoeia), and FCC (Food Chemicals Codex). These standards dictate the purity and impurity limits that the product must meet. The purity specification observed is 99%, a benchmark that buyers should verify through current Certificates of Analysis (CoA) for every batch. The EEC Number E211 is the specific regulatory identifier for sodium benzoate within the European Union, a critical data point for exporters targeting the European market.

Grade classification is another compliance pillar. The material is consistently described as "Food Grade," which distinguishes it from industrial-grade variants that may contain higher levels of heavy metals or other contaminants. The origin of the product is predominantly China, with specific production hubs noted in Shandong. While the location is a fact, the regulatory burden falls on the supplier to prove that their production in these regions meets the destination country's import requirements. Buyers must verify that the supplier's ISO22000 and HACCP certifications are current and valid for the specific manufacturing site, not just the corporate entity.

Cost Drivers and Pricing Dynamics

The pricing structure for sodium benzoate is influenced by several dynamic factors. The observed listed price range in the market spans from 1 to 1350 USD. This wide variance is not indicative of a single product but rather reflects differences in packaging sizes, purity grades, order volumes, and Incoterms. A unit price of 1 USD likely corresponds to a small sample or a specific bulk calculation method, whereas the upper end of the range may reflect specialized packaging, expedited shipping, or premium certification packages.

Minimum Order Quantity (MOQ) is a significant cost driver, with observed ranges between 1 and 1000 units. Suppliers with lower MOQs may charge a premium per kilogram to cover handling and administrative costs, while larger orders benefit from economies of scale. The production type is identified as "Syntheses Material," meaning the cost is tied to the price of raw petrochemical precursors and energy costs in the manufacturing region.

Packaging costs also play a role in the final price. The product is available in various packaging formats, including paper bags, kraft paper bags, and 25kg bags. The standard specification often lists 20kg/bag or 25kg/bag as the norm. Customization is available, which can alter the cost structure if the buyer requires specific labeling, palletization, or non-standard bag sizes. Buyers should request a detailed breakdown of costs, separating the material cost from packaging, certification, and logistics to understand the true value proposition.

Typical Applications and Functional Performance

Sodium benzoate is a versatile preservative with a broad spectrum of applications. Its primary function is as a bacteriostatic agent and antiseptic, effectively inhibiting the growth of bacteria, yeast, and mold in acidic environments. The observed applications include bread, cakes, drinks, and skincare products. This versatility allows the chemical to serve as a beverage preservative, a meat preservative, and a pastries preservative.

The efficacy of the preservative is dependent on the pH level of the product. It is most effective in acidic conditions, making it ideal for carbonated soft drinks, fruit juices, salad dressings, and pickled products. In the context of meat and pastries, it helps extend shelf life by preventing spoilage organisms. The storage instructions consistently recommend keeping the product in a cool, dry place, which is crucial for maintaining its chemical stability before use.

The property of the product is broadly categorized as food preservatives, but its specific use cases dictate the required purity. For instance, applications in skincare may require different impurity profiles compared to direct food additives. The shelf life of the product is generally listed as 2 years or greater than 12 months, provided it is stored under normal conditions. Buyers must ensure that the specific application they intend to use the preservative in aligns with the regulatory approvals for that product category in their target market.

Supplier Evaluation and Logistics Management

Evaluating suppliers requires a focus on origin, logistics capabilities, and production capacity. The primary production origin is China, with specific mentions of Shandong as a manufacturing hub. The transport ports are typically Qingdao or Shanghai, though any port in China may be available depending on the supplier's logistics network. The loading port is generally listed as a Chinese port, which implies that the buyer must arrange for freight forwarding or utilize the supplier's CIF/FOB terms.

Supplier reliability is often tied to their ability to handle customization. The market data indicates that customization is available, which suggests flexibility in packaging and potentially in labeling. However, buyers must verify the supplier's capacity to maintain consistent quality during customization. The production type is "Syntheses Material," indicating a chemical manufacturing process rather than extraction, which requires strict process control to ensure batch-to-batch consistency.

When evaluating a supplier, buyers should look for evidence of their storage methods. The standard storage method is "Normal," but the specific instruction is to store in a cool, dry place. A supplier with inadequate storage facilities could compromise the product quality before shipment. Furthermore, the packaging material is consistently listed as paper or kraft paper, which offers a balance of protection and environmental considerations. Buyers should inspect the integrity of the 25kg bag or 20kg bag specifications to ensure they are suitable for the intended transport mode, especially for long-haul ocean freight.

Quality Control and Long-Term Procurement Strategy

Quality control (QC) is an ongoing process that extends beyond the initial purchase. The standard specifications, such as 99% purity and drying loss ≤1.5%, must be verified through third-party testing for every significant shipment. The molecular formula C7H5NaO2 and the CAS number 532-32-1 serve as the baseline for identity testing. Buyers should insist on a Certificate of Analysis (CoA) that matches these specifications before accepting delivery.

Long-term procurement considerations involve building a relationship with suppliers who can provide consistent quality over time. The shelf life of the product is 2 years, which allows for some inventory buffering, but buyers should implement a First-In-First-Out (FIFO) system to prevent degradation. The property of the product as a food preservative means that any deviation in quality can lead to product recalls or regulatory fines in the end-user's market.

Buyers should also consider the standardization of their orders. With models like Z205 and Z206 available, standardizing the model number can simplify the procurement process and reduce the risk of receiving the wrong specification. The availability of customization allows for tailored solutions, but it also introduces complexity. A robust procurement strategy involves defining clear specifications upfront and communicating them effectively to the supplier to avoid misunderstandings regarding the grade, packaging, or certification requirements.

By adhering to these technical, regulatory, and logistical guidelines, buyers can navigate the complex market for food preservative sodium benzoate with confidence, ensuring that the sourced material meets the stringent demands of modern food safety and quality standards.
