In the cross-border circulation and domestic trade of chemical raw materials, the Harmonized System Code (HS Code) is a key compliance element throughout the entire process. Its accuracy is related to customs clearance efficiency, standardized tax accounting, and the smooth progress of trade procedures. As a commonly used raw material in the chemical industry, sodium persulfate is widely applied in various industrial scenarios such as electroplating, water treatment, mineral leaching, polymerization initiation, and textile dyeing & bleaching. Its corresponding HS Code is core information that purchasers, traders, and relevant practitioners must master. As a National Manufacturing Single Champion Enterprise recognized by the Ministry of Industry and Information Technology and a large-scale sodium persulfate supplier, Fujian Zhanhua Chemical provides spot wholesale services for customers while delivering professional compliance guidelines to facilitate the smooth progress of the entire trade process.

Ⅰ. Official Definition of HS Code for Sodium Persulfate

The HS Code for sodium persulfate follows unified international classification standards. The sodium persulfate supplied by Fujian Zhanhua Chemical corresponds to HS Code 28334000. This code is established by the Harmonized Commodity Description and Coding System of the World Customs Organization (WCO), serving as the legal basis for customs authorities of all countries to implement supervision, collect taxes, and conduct trade statistics on products.

The determination of this code is based on the chemical composition and basic characteristics of the product, ensuring its uniqueness and standardization in the global trade system. Whether in the declaration process of domestic trade or cross-border import and export business, accurately filling in this HS Code is the basic prerequisite for ensuring the legality and compliance of business activities. It can effectively avoid trade risks such as customs clearance delays and tax disputes caused by incorrect coding.

Ⅱ. Trade Supervision Corresponding to the HS Code

According to the classification of HS Code 28334000, sodium persulfate must comply with the corresponding customs supervision requirements throughout the entire trade process. As a National Manufacturing Single Champion Enterprise recognized by the Ministry of Industry and Information Technology, Fujian Zhanhua Chemical always takes compliance as the criterion to ensure that its spot wholesale business meets various national regulations.

Sodium persulfate is classified as Class 5.1 oxidizing dangerous goods. For cargo transportation, special vehicles for dangerous goods must be used; for warehousing, it must comply with storage specifications for oxidizing solids; during customs clearance, supporting documents such as product inspection reports, Material Safety Data Sheets (MSDS), and dangerous goods packaging performance inspection certificates must be provided.

Ⅲ. Core Value of HS Code in Trade

HS Code 28334000 has irreplaceable core value in sodium persulfate trade activities:

For Regulatory Authorities: It is a core tool for quickly identifying products, determining supervision standards, and implementing targeted classified supervision. It can greatly improve the efficiency of customs clearance audits and shorten cargo detention time.

For Trading Enterprises: It is the basis for ensuring declaration compliance and optimizing cost structures. At the same time, it can help enterprises avoid compliance risks caused by incorrect coding in advance and ensure the smooth progress of trade processes.

For International Cooperation: As an internationally recognized "identity card" for products, it eliminates product classification differences among different countries and regions, provides a unified standard for trade negotiations, document preparation, and settlement & payment, and reduces the costs and misunderstanding risks of cross-border communication.

Accurate application of HS Code helps all trade parties plan in advance, control costs and risks, improve the stability and efficiency of cooperation, and promote the standardized development of the market.

Ⅳ. Practical Guidelines for Code Inquiry and Application

For entities engaged in sodium persulfate trade, standardizing the inquiry and application of HS Code is a key link to ensure the smooth development of trade activities. Incorrect application of codes may lead to a series of problems such as failed customs audits, tax calculation deviations, and cargo seizure, causing unnecessary economic losses and time costs for enterprises.

In practical operations, it is recommended that relevant practitioners obtain accurate code information through official inquiry channels of the General Administration of Customs, authoritative chemical industry information platforms, or by consulting formal suppliers. Meanwhile, it is necessary to comprehensively verify the supervision requirements corresponding to the code in combination with the specific scenarios of trade business to ensure that the application of the code is consistent with the actual business situation. In addition, a regular policy tracking mechanism should be established to timely follow up on the adjustment dynamics of customs codes and relevant supervision policies, and continuously optimize trade processes in accordance with industry standard requirements to ensure that business activities are always in a compliant and controllable state.

The HS Code (28334000) is an indispensable important trade element in the spot wholesale business of sodium persulfate, and its accurate application plays a decisive role in trade compliance and efficiency. Fujian Zhanhua Chemical will always adhere to the concept of compliant operation, provide high-quality products for customers while conveying professional trade-related information, help all parties in the industry achieve efficient and compliant trade cooperation, and jointly promote the healthy and orderly development of the chemical raw material trade market.
