About Theone Chemical

Theone Chemical is a China-based supplier of phosphate chemicals for international customers, built on 20 years of chemical export experience. theonephos.com is our specialist phosphate site.

Our range covers technical grade, food grade and feed grade phosphates for detergent, water treatment, industrial, food processing and animal nutrition applications. Technical grade is our main line; food and feed grades complete the range.

What makes our supply different is that it runs on two modes. Buyers can choose the mode that fits their requirement — or combine both across different products.

Mode 1: Our Own Partner Bases

We work with partner production bases in Weifang and Deyang. These bases specialize in blended (compound) phosphates: instead of one fixed standard specification, the content and formulation are customized to your order — for example an adjusted P2O5 content, or a blend tuned to your application and cost target.

This mode suits buyers who need a specification the standard market grades do not match, or who buy regular volumes on a target price. You get made-to-spec product at partner-line prices, with batch COA and full export documentation supplied by us.

Mode 2: Branded Producer Sourcing

Some buyers require product from a specific caliber of producer — for tenders, regulated applications, or their own customer approvals. For them we source from China's large, established phosphate brands through our established purchasing channels.

Product in this mode follows the producer's standard specification and comes with original factory documents and a traceable supply origin. You get established-brand product without having to build the purchasing relationship yourself.

How We Work

Whichever mode you choose, the process is the same: tell us the product, grade or target specification, quantity and destination. We confirm the specification with you, quote with the supply mode stated openly, and support the order with specification confirmation, export packing, COA and product documents, and shipment coordination until delivery.

Pricing is transparent — offers come from a real production line, with no hidden markups, so you can compare openly.
