This guide is exclusively for legitimate enterprises holding the License for Hazardous Chemicals Operation, Work Safety License and corresponding storage qualifications. Entities without relevant qualifications are strictly prohibited from illegal storage or stocking beyond their qualifications, and illegal storage will bear corresponding legal responsibilities.

As the year-end approaches, affected by factors such as reduced holiday logistics, adjustments to enterprise production schedules, the chemical supply chain is prone to delays or temporary interruptions. As a strong oxidant, the procurement, storage and use of sodium persulfate must follow standardized procedures. Temporary procurement not only faces problems such as tight supply and delayed delivery, but may also increase costs due to emergency transfers. Insufficient reserves will directly lead to production suspension. To ensure the continuity of production and operation for our customers before and after the year-end, combined with the year-end production and logistics arrangements of Fujian Zhanhua Chemical, we specially formulate this exclusive stocking guide for sodium persulfate to provide accurate guidance for your stocking work.

Pre-Stocking Preparation: Clarify Needs and Plan Precisely

Before stocking sodium persulfate, it is necessary to base on actual usage needs, conduct comprehensive sorting and precise planning, so as to avoid resource waste or insufficient inventory caused by blind stocking.

• Clarify usage scenarios and dosage: Combine your own production and operation, work plans, predict the dosage demand during the year-end and a period after the holiday, and determine a reasonable total stocking quantity by comprehensively considering factors such as production load and operation frequency;

• Verify the current inventory status: Sort out the existing inventory in advance, check whether the materials have deteriorated or the packaging is damaged, and accurately calculate the quantity to be supplemented;

• Anchor the key nodes for Zhanhua’s stocking: Combined with the company’s year-end production arrangements, the shutdown time of the sodium persulfate production line this time is [February 9, 2026], the restart time after the holiday is [February 24, 2026], and the deadline for pre-holiday stocking orders is [February 5, 2026] (including logistics and distribution buffer period). All customers are requested to complete orders before the deadline according to their production plans to avoid delayed stocking due to production shutdown and logistics suspension.

At the same time, combined with the characteristics of sodium persulfate, it is recommended to reserve a reasonable inventory turnover space to meet emergency use and avoid quality changes caused by long-term backlog.

Core of Stocking: Choose Regular Channels and Control Quality & Price

The core of stocking is to ensure qualified material quality, reasonable price and stable delivery, and channel selection is the key premise. Priority should be given to regular suppliers with legal operation qualifications and good reputation to control quality from the source, eliminate the purchase of unqualified and unguaranteed products, and avoid safety accidents or impacts on operation effects. In terms of price and cooperation, negotiate with suppliers in advance to determine a reasonable price, clarify payment methods, delivery time and quality assurance clauses, and sign a formal purchase contract.

Storage Management: Scientific Storage to Ensure Safety and Stability

The scientific and standardized storage of sodium persulfate is not only the key to ensuring the stable quality of materials, but also the core of safe production in the warehouse. It is recommended to strictly follow the following storage requirements:

• Storage environment: Choose a cool, dry and well-ventilated place, away from heat sources, fire sources and direct sunlight, and keep low humidity;

• Isolated storage: Strictly store separately from organic substances, reducing agents, flammables, strong acids, strong alkalis and metal powders, etc. Mixed storage is strictly prohibited to prevent dangerous chemical reactions;

• Packaging and inspection: Keep the packaging containers tightly sealed to prevent leakage and moisture absorption, and ensure clear and complete labels; establish a regular inspection system to timely check and handle abnormalities such as damaged packaging, caked or discolored materials.

As the year-end approaches, scientific stocking of sodium persulfate is a necessary guarantee for the smooth progress of production plans and the pre-management of supply chain risks. It is necessary to comprehensively consider links such as demand planning, channel quality and storage safety.

Combined with the particularity of logistics and production cycles before and after the year-end, Fujian Zhanhua Chemical reminds again: All customers are requested to start the stocking work as soon as possible, complete inventory counting and dosage calculation, and ensure that orders are placed before the pre-holiday stocking deadline of [February 5, 2026].
