Questions, answered before you pay.

You tell us the chemical, grade, quantity and packing you need. A person on our team picks a real Chinese factory we would stand behind, checks its business licence and credit code, and sends you its details with a dated price guide and our advice. It arrives in your account within two business days.

Your first Factory Match is free, with no card. Starter includes 20 a month for USD 59, and Pro includes 50 a month for USD 149. Compare the plans.

The factory name in English and Chinese, its city, the credit code and whether it passes the check digit test, whether the licence shows it makes the product or only trades it, its permits and export record, a named contact, a dated price guide, and our advice on what to watch for.

Sometimes, when the right factory depends on a detail such as the grade, the packing or the port. The question appears on your request page and we email you a link, so you can answer from your phone in a few seconds.

We tell you so, with the reason, and that request does not count against your monthly allowance. We would rather send nothing than send a factory we do not trust.

Never. Factories pay us no commission, no listing fee and nothing else. Buyers are the only people who pay us, so the factory we send is the one we would use ourselves. See how we make money.

Free costs nothing and includes one Factory Match and every free tool. Starter is USD 59 a month with 20 Factory Matches, and Pro is USD 149 a month with 50 Factory Matches and faster delivery. Both paid plans are billed monthly by Stripe.

Starter and Pro both start with a 3 day trial that includes 3 Factory Matches. Stripe takes your card at the start, nothing is charged during the trial, and you can cancel from your account before it ends.

Yes. Choose the other plan and we switch your existing subscription, so you never pay for two. Stripe adjusts the bill for the rest of the month, so you only pay the difference.

You can move up a plan, or buy extra Factory Matches at USD 9 each. Extra matches never expire, and one we cannot fill is given back.

Yes. Cancel from your account and the plan stays active until the end of the period you have paid for. Matches already delivered stay in your account.

Type a chemical, a CAS number, a tariff code, a supplier name or a Chinese credit code. Sourzi checks the chemical registers, import duty, anti dumping cases, sanctions and forced labour lists and the company code, and shows the official file and date behind every answer.

From official files such as tariff schedules, anti dumping case lists, sanctions lists and chemical registers. Every answer shows the file it came from and the date we read it. When a file does not store a number, Sourzi says so instead of guessing one.

Most of them are. The calculators and converters run in your browser, so the numbers you type do not leave your computer. A few lookups that use large official files are on the paid plans. Open all tools.

Ask a question in plain words, or out loud, and Sourzi answers only from the facts in its own files, with the source beside each one. You get 5 free questions a day, and the paid plans have no daily limit. Ask a question.

No. Sourzi is information for planning your purchase, built from official files. Your customs broker still files the entry, and a name that is not on a list has not been cleared by that list.

A team that has bought chemicals from China for twenty years: more than 1,200 shipments and more than 100 factories. The team is based in Shanghai Pudong. Read about us.

Yes, for a small number of orders. Our Shanghai team can sample, inspect and manage the order for a fee you agree before we start. The fee is paid by you, never by the factory. Talk to our team.

Yes. An in person factory audit costs USD 299, and it is free when you then place the order through Sourzi. We report against a 30 point checklist.

We email you a sign in link, so there is no password to remember. You can set a password later from your account if you prefer one.

When Ask Sourzi writes an answer, your question and the facts Sourzi found are sent to our AI provider, OpenAI, to write the reply, so please leave personal details out. When you speak a question, your browser turns it into text first, and Sourzi never receives the audio. Read the privacy policy.

Stripe does. Card details are never stored on Sourzi, and Stripe handles them under PCI DSS Level 1.
