The molecular weight for this compound is approximately 105.99 g/mol. In the marketplace, buyers will encounter variations in purity and physical appearance that directly impact performance. High-quality odor-absorbing agents typically present as a white powder or white powdered crystal.

Purity is a critical differentiator. Market observations indicate that food-grade variants often boast a minimum purity of 99.2%, while industrial grades may range from 90% to 99% or higher, with some specifications requiring a minimum of 99%. The solubility profile is another essential technical attribute; sodium bicarbonate is easily soluble in water, a characteristic that facilitates its use in cleaning solutions and chemical processes. The classification of the product is often listed as "Carbonate," specifically "Sodium Bicarbonate," though some listings may refer to "Sodium Carbonate" (Na2CO3) with a molecular formula of Na2CO3 and CAS 497-19-8, which buyers must carefully distinguish as the chemical properties differ significantly.

Granularity also plays a role in efficacy. Some industrial specifications list granularity at 99.5%, indicating a high degree of uniformity in particle size, which can affect the surface area available for odor neutralization. The standard classification for these products often includes "Food Grade" or "Industrial Grade," and sometimes a dual designation like "Food Grade Industry Grade" depending on the purity level and intended use case.

Compliance, Certification, and Regulatory Standards

For B2B procurement, verifying compliance with international and local standards is non-negotiable. The supply chain for sodium bicarbonate is heavily regulated, particularly when the product is intended for food contact or pharmaceutical applications. Buyers should expect to see certifications such as GMP (Good Manufacturing Practice), ISO, and QS (Quality System) on product documentation. Specific standards like ISO 9001 are frequently cited, indicating a supplier's commitment to quality management systems.

In addition to general quality certifications, buyers should look for specific product certificates such as COA (Certificate of Analysis), BV (Bureau Veritas), and SGS reports. These documents provide third-party verification of the product's chemical composition, purity, and safety. For industrial applications, RoHS compliance may also be relevant, ensuring the material does not contain restricted hazardous substances. The product standard is often listed as FCC (Food Chemicals Codex) for food-grade items, while industrial grades may adhere to other unspecified standards or internal company specifications.

It is crucial to note that while many suppliers list "ISO" or "ISO 9001" as a certification, buyers must verify the validity of these certificates through the issuing bodies. The presence of a certification on a product listing does not automatically guarantee that every batch meets the standard; it indicates the supplier's capability to produce compliant goods. Buyers should request current, batch-specific COAs to ensure that the specific shipment meets the required purity and safety thresholds before finalizing the purchase.

Cost Drivers and Pricing Dynamics

The pricing of odor-absorbing baking soda is influenced by several factors, including grade, purity, packaging, and order volume. The observed price range in the market spans from $0.40 to $1,400, a wide variance that reflects the difference between bulk industrial raw materials and specialized, high-purity food-grade packaging. The minimum order quantity (MOQ) is another significant cost driver, ranging from 1 unit to 500 units, with some industrial suppliers requiring substantial bulk orders, such as 27 tons, to achieve optimal pricing.

Packaging costs are embedded in the final price. Common packaging formats include PP bags with PE liners inside, which protect the product from moisture and contamination. Standard weights for these bags are 25kg, 50kg, or 100kg, with bulk options available up to 1000kg. The choice of packaging directly impacts the unit price; smaller, retail-ready packages will carry a higher cost per kilogram compared to bulk industrial bags. Customization of packaging is often available, which can add to the cost but may be necessary for specific logistics or branding requirements.

Lead times also affect the total cost of ownership. Typical delivery times are within 15 days, but this can vary based on the supplier's location, specifically in regions like Shandong, China. Buyers should factor in potential delays due to customs clearance, shipping logistics, and seasonal demand fluctuations. Understanding these cost drivers allows procurement teams to negotiate more effectively and select suppliers that offer the best balance between price, quality, and delivery speed.

Typical Applications and Usage Scenarios

The versatility of sodium bicarbonate makes it suitable for a broad spectrum of applications. In the food industry, it is used for digestion support, energy replenishment, and increasing milk production in livestock, highlighting its role as a nutritional additive. For odor absorption specifically, its alkaline nature allows it to neutralize acidic odors in various environments.

In industrial settings, sodium bicarbonate is utilized in metallurgy, glass manufacturing, textile processing, and dye printing. Its classification as a "Basic Material" underscores its role as a foundational chemical in these processes.
