About

Independent China-based sourcing agent for industrial chemicals and fertilizers. 6+ years factory-side in China, 500+ factories, 13+ product lines. End to end: verification, COA, inspection, shipping.

I'm Liang Jiayuan. I buy chemicals in China so you don't have to.

Six years on the factory side, then negotiating at the plant, now running sourcing for buyers end to end. This is how I work now: one person, one channel, from first email to your port.

01 How I got here

I started on the product side, not the sales side.

For the first few years I was inside the plants. Opening samples, arguing specs with the lab, chasing production schedules that always slipped. I learned fast which factories actually run what they print on their website, and which ones quietly change the grade between the sample and the bulk order.

Later I started helping overseas buyers who kept hitting the same wall. Alibaba gave them a factory name, a price, and a handshake. When the container arrived off-spec, there was no one on the ground to call. So I started doing the job properly: verifying the plant, comparing three to five factories side by side, checking the COA before loading, and being the person who answers the phone when something goes wrong.

02 Why a solo practice

You talk to the person doing the work.

I could work for a trading house. I chose not to. A trading company has sales targets, a minimum order book to hit, and a product manager who rotates every two years. You end up talking to whoever happens to be on shift.

I'm a solo practice out of Changsha. The person who reads your COA is the same person who visits the plant, calls the factory when the schedule slips, and signs your B/L. If something goes wrong at your dock, you don't get bounced between a sales rep and a support queue. You get me.

03 How I charge

Agreed upfront. No hidden layers.

My service fee is agreed in writing before any order is placed. You see the ex-works price from the factory; you know exactly what my service costs. No hidden fees. The price you see is the factory price plus my agreed service fee.

If you only need a factory phone number, I'm not the right fit. If you need someone to run the buying job end to end, we should talk.

FAQ Questions buyers ask

Straight answers, before you ask.

Can I deal with the factory directly after the first order?

Technically yes. But quality, schedules and after-sales are ongoing work. If you take it over, the follow-up becomes yours. If my service stops earning its fee, end the contract. No lock-in.

How do you charge?

Service fee agreed in writing before any order, on top of the ex-works price you see. No hidden markup. Larger orders get a reduced rate.

Do you sell factory lists?

No. I run the buying job end to end. If all you need is a phone number, I'm not the right fit. I'll say so upfront.

How do I know the quality is right?

COA verified before loading, SGS or CIQ inspection on request, samples kept from each batch. I'd rather catch a problem in China than at your dock.
