We wrote the standard
Gaoyuan organised and compiled HG/T 3250-2023, the Chinese industry standard for industrial sodium chlorite, after taking part in the 2010 revision before it.
Sodium chlorite manufacturer · China
China’s largest producer
of sodium chlorite.
Gaoyuan has been making sodium chlorite since 1997 and organised the HG/T 3250-2023 industry standard it is made to. NSF listed, REACH registered, and exported to 50+ countries. Exports account for 50% of our annual output.
Why buyers come here
The producer that wrote the rulebook.
Sodium chlorite is a commodity until it is not — until your market needs a drinking water listing, a REACH registration, or a supplier who can explain what happens above 170 °C. That is the part we are built for.
Listed where it matters
Our sodium chlorite appears on the official US inventory of drinking water treatment chemicals under NSF, and is registered under EU REACH.
Backed by a listed group
A subsidiary of Sunvim Group Co., Ltd., a listed enterprise, since 2008. The plant holds ISO 9001, ISO 14001 and ISO 45001 certification alongside the national Safety Production Licence.
Products
Two products, both made on our own lines.
We do not trade other people’s material. Everything below comes off plant we own and operate in Gaomi, Shandong.

How an order runs
Four steps from enquiry to shipment.
The end use decides the grade, and the grade decides everything after it. That is why the first question we ask is what the material is for.
- 01
Tell us the end use
Drinking water, textile bleaching, pulp, aquaculture or flue gas. The application decides the grade before anything else.
- 02
Grade and quotation
We come back with the grade, the concentration, the certificates that apply to your market and indicative FOB pricing.
- 03
Sample and documentation
A sample with the documentation your lab needs to verify it, before you commit to a container.
- 04
Production and shipment
Packed to your specification, documented for hazardous goods transport, and shipped — usually out of Qingdao.
Export experience
Exports are half our annual output.
We started exporting in 2003, earlier than anyone else in this sector in China, and have shipped to more than 50 countries since — the United States, Brazil, the United Kingdom, Australia, Japan and South Korea among them. Sodium chlorite is a regulated oxidiser, so every shipment travels with the hazardous goods documentation its route requires.

How to read a sodium chlorite certificate of analysis
A COA is not a marketing document. It is a statement about one batch, and it is only useful if you know which questions it answers and which it does not.
Shipping sodium chlorite: UN 1908, packing options and what the paperwork has to match
Net weights, transport classification and the documents that have to agree with each other. Written for the person who has to book the freight, not for the person who signs the contract.
