100+ FACTORIES.
ONE RULE: GO DIRECT.
Our operation is built on twenty years of direct factory relationships across Shandong, Jiangsu, Zhejiang, and Anhui. Every supplier is visited in person, every contract negotiated in Mandarin with factory management, and every batch inspected by SGS or Bureau Veritas before it leaves China. There is no listing platform here, no anonymous broker margin, and no catalogue that updates itself.

搜子
SŌU ZǏ · THE SEARCHER
搜 means to search, to hunt, to seek out the source. 子 is classical Chinese for master or expert. 孔子 is Confucius. 老子 is Laozi. The suffix denotes the one who knows.
Romanised: Sourzi. Source, compressed. Two syllables. The name reflects the function: find the right factory, the right grade, the right price, and close the deal directly.
Established 2012
Operations began in Shanghai Pudong after a decade of direct China trade. Factory relationships built in person, in Mandarin, on production floors in Shandong, Zhejiang, and Jiangsu.
Over two decades we have shipped titanium dioxide, sodium hydrosulfide, dimethyl disulfide, molecular sieves, activated carbon, citric acid FCC grade, and dozens more. If it ships by drum, IBC, bulk bag, or ISO tank, our team has handled it.

Why Sourzi
HOW WE OPERATE.
IN PERSON NOT VIDEO CALLS
Every new factory relationship begins with a physical visit from Shanghai Pudong. We walk the production floor, check storage conditions, verify export licenses, and collect samples under our direct supervision.
NEGOTIATION IN MANDARIN
Price, specification, and delivery terms negotiated directly with factory management in Mandarin. No intermediary, no translation loss. Factory floor Mandarin is different from textbook Mandarin — we speak both.
SGS INSPECTION EVERY BATCH
SGS or Bureau Veritas pre-shipment inspection is standard on every order. The Certificate of Analysis and inspection report issue before the container seals and before the balance payment is triggered.
DANGEROUS GOODS CERTIFIED
Certified for IMDG Classes 3, 4, 5.2, 6.1, and 8. Every DG shipment includes UN certified packaging, a Dangerous Goods Declaration, and a full MSDS package compliant with destination country requirements.
FULL DOCUMENTATION SET
Every shipment: commercial invoice, packing list, COA, MSDS, Certificate of Origin, Bill of Lading. Dangerous goods orders include DG Declaration and UN packaging certification. All issued before vessel departure.
USD PRICING LANDED COST
All pricing in US dollars. Every quote includes a full landed cost breakdown: sea freight, marine insurance, and destination import duty estimate based on HS code. No hidden charges on arrival.
