What you see on a Chinese factory tour and what to ask about it: workshops, lines, warehouses, inspection points, certifications, and the questions that show whether the factory really makes your product.
参观 (cānguān) is "to visit and look," and the factory will show you its best line. The tour is still the one chance to see whether the company that quoted you makes the product itself, or sends parts of it out to other workshops (外发 wàifā, or 外包 wàibāo). Look for the processes your product needs on the floor: if a bottle needs deep drawing, welding, vacuum sealing, and powder coating, and you only see assembly and packing, ask where the rest happens. Ask permission before taking photos (可以拍照吗 kěyǐ pāizhào ma?); most factories allow it outside rooms with other customers' products.

How are raw materials labelled when they arrive? Can you trace them to the batch?
质检zhìjiǎnInspection Points and Certificates
三道检验 sān dào jiǎnyàn · Three Checkpoints来料检验 IQC láiliào jiǎnyàn → incoming materials 过程检验 IPQC guòchéng jiǎnyàn → during production, on the line 出货检验 OQC chūhuò jiǎnyàn → finished goods before shipment
质检zhìjiǎnquality inspection
Short for 质量检验. 品管 (pǐnguǎn) or 品质部 is the quality department. Ask to see the inspection records (检验记录 jiǎnyàn jìlù) for a recent batch, not only the procedure.
Néng kàn yíxià shàng zhōu chūhuò de jiǎnyàn jìlù ma?
Could I see the inspection records for last week's shipment?
认证rènzhèngcertification
ISO 9001 is 质量管理体系认证 (the quality management system certificate). 验厂 (yànchǎng) is a factory audit, such as BSCI for social compliance. Check the certificate's 有效期 and that the company name matches the one you are contracting with.
Nǐmen de ISO zhèngshū shì nǎge gōngsī míng xià de? Yǒuxiàoqī dào shénme shíhou?
Which company is your ISO certificate issued to, and until when is it valid?
提问tíwènQuestions to Ask on the Floor
外发wàifāto send out (to a subcontractor)
The question the tour exists to answer. A factory that sends out a step is not necessarily hiding anything, but you need to know, because quality on that step is out of its direct control.
How many shifts are you running now, and how many workers in total?
客户kèhùcustomer
Factories like to name famous customers. The useful questions are which markets they ship to, and how much of the output the largest customer takes (占比 zhànbǐ, share), since a dominant customer gets the line first in peak season.
