Sanxin International Electric (Shanghai) Co., Ltd appears in 36 editions of the Canton Fair exhibitor list, a run of more than ten years. The Canton Fair (China Import and Export Fair) is held in Guangzhou each April and October; exhibitor lists are published per session, so a company missing from one session may simply not have booked that time.
Working with a supplier like this
Sanxin International Electric (Shanghai) Co., Ltd is one of tens of thousands of Chinese exporters that meet overseas buyers through the Canton Fair. If you are approaching a company in consumer electronics & it, the practical questions are usually the same.
Meeting them at the fair
- Booth allocations are published per session and change every time. Confirm the current hall and booth with the company or through the official Canton Fair channels before you travel.
- A manufacturer’s booth staff are often technical rather than fluent in your language. An interpreter who knows the product vocabulary changes what you can actually ask in a 20-minute meeting.
- Factory visits after the fair are common and are where most of the real due diligence happens. Guangzhou, Shenzhen, Yiwu and Ningbo are all within a few hours of the fairground.
Paperwork to expect
- Product specifications, datasheets and test reports — often written in Chinese first.
- Quotations and proforma invoices, then the sales contract. For OEM or ODM work, add tooling agreements, drawings and sometimes an NDA.
- Export documents: commercial invoice, packing list, bill of lading, certificate of origin, and any certification your own market requires.
- Where a contract is signed in two languages, agree in writing which language governs if the versions disagree.

Do I need an interpreter to deal with a Canton Fair exhibitor?
