Important Reminder | Shanghai Maritime Safety Administration optimizes the EDI declaration process for shipborne dangerous goods; Jiayuan Chemical reminds customers to switch to the new platform in a timely manner. Source: Changzhou Jiayuan Chemical Co., Ltd.Release Date: 2026-09-21  To further optimize the business environment of Shanghai Port and improve the efficiency of port and shipping companies, the Shanghai Maritime Safety Administration issued a "Notice on Optimizing the Procedures for Opening Accounts and Changing Information in the Shipborne Dangerous Goods EDI Declaration System" on February 9, 2026. Changzhou Jiayuan Chemical Co., Ltd. reminds its customers and partners to promptly understand and follow the new procedures to avoid affecting the declaration of shipborne dangerous goods and container loading reports. According to the notice, effective immediately, the Shanghai Maritime Safety Administration will uniformly accept applications for account opening and information changes for the shipborne dangerous goods EDI declaration system through the "China (Shanghai) International Trade Single Window" (hereinafter referred to as the "Single Window"). The original "Chemicals Management Service Platform" will no longer accept related applications. The specific processing procedure is as follows:https://www.singlewindow.sh.cn/winx-portal/#/home The operation manual for handling business can be downloaded from the following website:www.singlewindow.sh.cn/winx-portal/#/winxColumn/instructions Units that already have a "Single Window" account can log in directly without registering a new account. Application materials submitted through the "Chemicals Management Service Platform" before the date of this notice will still be verified by the Shanghai Maritime Safety Administration in the original manner; no further submission is required. Furthermore, the notice clarifies that, effective immediately, for small, mobile tank containers transported via containers, the mobile tank container inspection certificate can be used as proof of packaging inspection compliance, allowing for direct processing of relevant declarations or reports. To standardize and facilitate the reporting of container loading operations for shipborne dangerous goods, all loading units are requested to supplement and improve their operational information and upload relevant supporting documents on the new platform by March 31, 2026.

What Are the Advantages of High-Purity Potassium Fluoride Over Standard Potassium Fluoride?

High-purity potassium fluoride (KF) offers significant advantages over standard industrial-grade potassium fluoride, particularly in applications where material purity and process consistency are critical. Due to its lower impurity levels and higher chemical stability, it is widely used in semiconductors, electronic chemicals, advanced materials, pharmaceuticals, and specialty chemical manufacturing. 1. Lower Impurity LevelsStandard potassium fluoride is suitable for general industrial applications, while high-purity potassium fluoride undergoes additional purification processes to significantly reduce impurities such as iron (Fe), sodium (Na), chloride (Cl⁻), and heavy metals.According to ACS-grade specifications published by Sigma-Aldrich and Merck, high-purity potassium fluoride can achieve purity levels above 99%, with iron content below 0.001% and chloride and sulfate levels below 0.005%. Lower impurity concentrations help minimize side reactions and improve product consistency.2. Better Suited for Electronics and Semiconductor ManufacturingIn semiconductor and electronic material production, even trace metal contamination can affect product yield and performance. High-purity potassium fluoride meets the stringent requirements of electronic-grade chemicals for low contamination and low impurity levels, making it suitable for advanced manufacturing applications.3. Improved Reaction Efficiency and Product QualityPotassium fluoride is commonly used as a fluorinating agent in organic synthesis, pharmaceutical intermediates, and specialty chemical production. Higher purity means fewer impurities interfere with the reaction process, improving selectivity and increasing target product yields while reducing batch-to-batch variations.4. Enhanced StabilityResearch has shown that impurities in fluoride systems can affect material stability and overall performance. High-purity potassium fluoride reduces the risk of performance degradation caused by contaminants, providing more stable results in demanding applications.High-Purity Potassium Fluoride vs. Standard Potassium FluorideParameterStandard Potassium FluorideHigh-Purity Potassium FluoridePurity95%–99%Above 99%Metal ImpuritiesHigherLowerProduct StabilityStandardEnhancedSemiconductor ApplicationsLimitedSuitableFine Chemical ManufacturingGeneral UseRecommended for High-End ApplicationsConclusionFor general industrial applications, standard potassium fluoride is often sufficient. However, for semiconductors, electronic chemicals, new energy materials, and high-value specialty chemicals, high-purity potassium fluoride offers clear advantages through lower impurity levels, greater stability, and improved process consistency. As quality requirements continue to increase across advanced manufacturing industries, high-purity potassium fluoride is becoming an increasingly important raw material.Frequently Asked Questions (FAQ)1. What is the main difference between high-purity potassium fluoride and standard potassium fluoride?The primary difference is purity and impurity control. High-purity potassium fluoride contains significantly lower levels of metal impurities, moisture, and unwanted ions, making it suitable for industries with strict quality requirements such as semiconductors, electronic materials, and specialty chemicals.2. Which industries commonly use high-purity potassium fluoride?High-purity potassium fluoride is widely used in semiconductor manufacturing, electronic chemicals, new energy materials, photovoltaic applications, pharmaceutical intermediates, and high-end specialty chemical production. These industries require high levels of purity, stability, and production consistency.3. Is high-purity potassium fluoride worth using instead of standard potassium fluoride?For conventional industrial processes, standard potassium fluoride may be adequate. However, in applications where impurity control, product yield, and process stability are critical, high-purity potassium fluoride can provide better performance and higher product quality, making it a valuable choice for advanced manufacturing.
