One at a time
Factory check
$200 per check
Name a Chinese supplier. We verify who they really are, score them on quality, capacity, compliance, price, export record and financial strength, and tell you whether and how to buy.
Find top factories
$600 per report
Share your product and requirements. We shortlist 1–5 Chinese manufacturers, assessed on quality, capacity, compliance and risk. Every recommendation is evidence-based.
It counts as used when we deliver the shortlist, even if our answer is that we cannot recommend a factory.
Supplier files
$150 per factory
We ask the supplier for its documents and certificates on your behalf.
Company deep-dive
$300 per company
Everything we can find on one supplier: 28 points from ownership and finances to production, a weighted scorecard, and the report as PDFs in English and Chinese.
It counts as used when we deliver the report, even where public sources don't cover every item.
Single purchases never expire.
