Screen China suppliers before an RFQ
Screening is a decision about evidence relevant to your brief. A supplier can be worth approaching even when one exact product dimension still needs confirmation; that gap must remain visible.
A successful China Supply Check returns three distinct evidence-backed China supplier candidates worth advancing to RFQ. x402 payment is live at 2.99 USDC on Base. Image Stripe hosted Checkout is live for USD 2.99; legacy text/model Stripe is OFF. Free brief preparation uses MCP; preparation does not purchase a check.
Which candidates should advance, and which need a specific question first?
Illustrative brief: 1,000 printed corrugated boxes, a specified internal size and board grade. A plain stock box may be a useful supplier lead, but it is not proof of custom-print capability at your quantity.
Separate mismatch, missing evidence and acceptable alternatives
A source that explicitly contradicts a mandatory requirement supports a mismatch finding. A source that omits it supports an unknown, not a failure or a pass. Permit alternatives only when your brief permits substitution. Keeping these states distinct prevents both false rejection of capable suppliers and false certainty about exact product fit.
Screen the candidates returned for your brief
China Supply Check finds and screens candidates for a specified product. This guide does not describe a buyer-uploaded arbitrary supplier list or a separate verification product. The successful output is three distinct RFQ-worthy supplier candidates, with evidence and open questions. Exact product qualification remains a separate, field-specific judgment.
What to read before the next step
| Field | Decision use |
|---|---|
| Hard requirements | Read material, model and dimensions against the buyer brief. |
| MOQ fit | Check minimum quantity and compatible units; do not assume a supplier will waive MOQ. |
| Substitution | Retain the original requirement and whether the proposed alternative was permitted. |
| Decision gap | State which missing fact could change the RFQ decision. |
What to ask next
- Confirm the unresolved mandatory attribute with the supplier.
- Ask whether customization changes MOQ, tooling or sample requirements.
- Keep rejected mismatches separate from candidates awaiting a factual answer.
Keep unknowns specific
Missing certification or price-tier applicability belongs to the corresponding field. It must not become a blanket claim that the entire supplier is unverified, unreachable or commercially unusable.
No suppliers are contacted by reading this guide or preparing a brief. Supplier outreach and RFQ execution are separate from the screening purchase.
After the shortlist, an overseas buyer or AI Agent can ask SeekAPI to review a separate China-side assignment: selected-supplier contact, authorized RFQ and quote comparison, sample follow-up, procurement or export coordination. A person must accept an agreed scope, fee, recipients and authority before work begins; the human-task API and fixed-price Live RFQ Compare package are not live.
