Find white liquid sulfentrazone herbicide for soil, leaf, and crop use

Sourcing Guide for White Liquid Sulfentrazone Herbicide Procurement

The procurement of agricultural chemical inputs, specifically herbicides like sulfentrazone, requires a rigorous approach to ensure efficacy, safety, and regulatory compliance. Buyers searching for a "white liquid sulfentrazone herbicide" must navigate a complex landscape of formulation types, physical states, and supplier capabilities. While the core keyword suggests a specific physical appearance and chemical identity, the actual market data reveals a diverse range of product forms, including powders, granules, and various liquid suspensions. This guide provides a structured framework for evaluating potential suppliers and products based on verified technical attributes, compliance standards, and logistical requirements.

Understanding Product Formulations and Physical Attributes

The first critical step in sourcing is reconciling the search term "white liquid" with the available product data. The market for sulfentrazone includes multiple formulation types, each with distinct physical properties and application methods. The supplied facts indicate that sulfentrazone is available in several specific formulations, including 40% SC (Suspension Concentrate), 50% SC, and 75% WDG (Water Dispersible Granule). The "SC" designation typically refers to a liquid formulation, which aligns with the "liquid" aspect of the search query. However, the data also explicitly lists "White powder" and "White solid" as observed appearances for related herbicide products, and "Granules" for other entries.

It is essential for buyers to verify the exact physical state of the product they intend to purchase. While the keyword implies a liquid, the data shows that sulfentrazone products can also be supplied as white powders or solids. The molecular weight of the active ingredient is listed as 438.8 in some contexts and 387.1899 in others, suggesting variations in the specific chemical representation or impurity profiles across different batches or suppliers. The boiling point is recorded at 468.2, and the vapor pressure is extremely low at 6.1E-09mmHg, indicating low volatility. The pH range for these products is typically between 5.0 and 8.0. Buyers must confirm whether the specific "white liquid" they require is a suspension concentrate (SC) or if they are misinterpreting a powder that disperses in water. The appearance of the final product in the drum or bag may differ from the appearance of the active ingredient in its pure form.

Technical Specifications and Chemical Identity

When evaluating the technical specifications of sulfentrazone herbicides, buyers must look beyond the generic name and examine the specific chemical data provided. The molecular formula for the active ingredient is cited as C11h10cl2f2n4o3s. This precise chemical identity is crucial for ensuring that the product meets the intended agronomic requirements. The melting point (M.p.) is noted as 219 C, and the pKa is 2.83, which influences the solubility and behavior of the herbicide in different soil pH environments.

The density or specific gravity is a key parameter for liquid formulations, with a value of 1.72g/cm3 observed in the data. This high density suggests that the liquid formulations are concentrated and may require careful handling during transport and mixing. The flash point is recorded at 237, which is a critical safety parameter for storage and shipping, indicating the temperature at which the product can ignite. Buyers should verify that the specific batch they are sourcing matches these physical constants, as deviations could indicate degradation or the presence of unauthorized solvents.

Furthermore, the method of application is a vital technical consideration. The data lists "Cauline Leaf" and "Soil Treatment Agent" as application methods. This indicates that the herbicide can be applied to the foliage of the plant or directly to the soil. The usage type is described as both "Non-Selective" and "Selective" in different entries, which is a significant contradiction that requires immediate clarification. A non-selective herbicide kills all vegetation, while a selective one targets specific weeds. Buyers must explicitly confirm the selectivity profile of the product to ensure it will not damage the desired crop. The specific conductivity is also mentioned, with references to "The Herbicide Transmitting" and "The Tag Type Herbicides," though these terms require further definition by the supplier to ensure they align with the buyer's technical requirements.

Compliance, Certification, and Regulatory Standards

Compliance with international and local standards is non-negotiable in the procurement of agricultural chemicals. The supplied facts mention several standards, including GB (Guobiao), FAO (Food and Agriculture Organization), and SGS (Société Générale de Surveillance). These designations suggest that reputable suppliers adhere to specific quality and safety protocols. The standard "90%" is also listed, which may refer to the purity of the active ingredient (TC) or a specific quality grade.

Buyers must verify that the product meets the specific regulatory requirements of their destination country. While the data mentions "SGS" and "GB/FAO/SGS," it does not confirm the certification status of every listed product. Therefore, procurement teams should request current certification documents for the specific batch being purchased. The origin of the products is consistently listed as Shanghai, China, or generally "China." This geographic information is useful for logistics planning but does not guarantee compliance with the regulations of the importing country.

Additionally, the product model numbers, such as "Herbicdie" (likely a typo for Herbicide) or specific codes like "Sulfentrazone 40%SC," serve as identifiers for the formulation. Buyers should ensure that the product model matches the regulatory approval status in their region. The absence of specific certification names like "ISO" or "EPA" in the provided facts means that buyers cannot assume these certifications are present without direct verification from the supplier. The standard "Oxyfluorfen" is also listed, which is a different herbicide; buyers must ensure they are not confusing sulfentrazone with other chemical classes.

Cost Drivers and Packaging Logistics

The cost of sourcing sulfentrazone herbicides is influenced by several factors, including the formulation type, packaging, and order volume. The observed price range in the market is between 1 and 100 USD, though this likely refers to per-unit pricing for small samples or specific packaging sizes rather than bulk commodity pricing. The Minimum Order Quantity (MOQ) ranges from 1 to 2000 units, offering flexibility for both small-scale trials and large-scale commercial procurement.

Packaging options are diverse and directly impact the total cost and handling requirements. The data lists various packaging formats, including 1kg Aluminum Foil Bags, 5kg/10kg/25kg Fiber Drums, 25kg Drums, 25kg Bags, and 200L Drums. For liquid formulations, 200L drums and 20L drums are common, while powders and granules are often supplied in 25kg bags or drums. The ability to customize packaging "According to Customer's Requirements" is a significant advantage for buyers with specific logistical needs.

Lead times and shipping costs are also critical cost drivers. While specific lead times are not provided in the facts, the origin in Shanghai suggests that buyers should account for international shipping durations. The high density of the liquid formulation (1.72g/cm3) means that shipping costs will be heavily influenced by weight rather than volume. Buyers should negotiate terms that clearly define who bears the risk of damage during transit, especially for fragile packaging like aluminum foil bags or fiber drums.

Supplier Evaluation and Quality Control

Evaluating suppliers requires a focus on their ability to provide consistent quality and technical support. The data indicates that "Free" samples are available, which is an excellent opportunity for buyers to test the product's physical properties and efficacy before committing to a large order. The presence of customization options for packaging and formulation suggests that suppliers are willing to adapt to specific buyer needs.

Quality control should be a central part of the supplier evaluation process. Buyers should request test reports that verify the active ingredient content, ensuring it matches the claimed percentage (e.g., 95% TC, 75% WDG, 40% SC). The molecular weight and other chemical constants should be cross-referenced with the test results. Additionally, buyers should verify the supplier's track record in handling hazardous materials, given the flash point and vapor pressure data.

The "Specific Conductivity" and "Method of Application" data points highlight the need for technical expertise. A reliable supplier should be able to provide detailed application guidelines, including dosage rates, timing, and compatibility with other agrochemicals. The discrepancy between "Non-Selective" and "Selective" usage in the data underscores the importance of clear communication. Buyers must ensure that the supplier explicitly states the selectivity profile of the product to avoid crop damage.

Long-Term Procurement Considerations

For long-term procurement, buyers should consider the stability of the supply chain and the availability of the product. The consistent origin in Shanghai suggests a stable manufacturing base, but buyers should assess the supplier's capacity to scale production if demand increases. The availability of different formulations (SC, WDG, TC) allows for flexibility in sourcing, but buyers should establish a preferred formulation based on their specific application needs.

Sustainability and environmental impact are increasingly important in procurement. The low vapor pressure and specific boiling point of sulfentrazone suggest that it is relatively stable, but buyers should inquire about the environmental fate of the product and any disposal requirements for empty containers. The "destiny" parameter, listed as 1.72g/cm3, may relate to the environmental behavior of the chemical, though this term is ambiguous and requires clarification.

Finally, buyers should maintain a robust record-keeping system for all procurement activities. This includes tracking batch numbers, test results, and supplier communications. This documentation is essential for troubleshooting any issues that arise during application and for ensuring compliance with regulatory audits. By focusing on these long-term considerations, buyers can build a resilient supply chain that supports their agricultural operations effectively.

Comparative Analysis of Product Variants

To assist buyers in making informed decisions, the following table summarizes the key differences between the observed product variants based on the supplied facts. This comparison highlights the variations in formulation, appearance, and packaging that buyers must navigate.

This table illustrates that while the core chemical (sulfentrazone) remains constant, the physical form and packaging vary significantly. Buyers must align their specific needs with the correct variant to ensure successful procurement and application. The data also shows that some entries list "Oxyfluorfen" as a standard, which is a distinct herbicide; buyers must be vigilant to avoid mixing up product specifications. By carefully reviewing these attributes and verifying them with the supplier, buyers can secure high-quality sulfentrazone herbicides that meet their operational requirements.
