How can a product photo become a precise China supplier search?
Use the photo to explain the main product you want, then state the quantity and specifications that must match. Keep visible features separate from dimensions, materials or performance that the image cannot prove. Review the editable interpretation before purchase. Similar appearance can help locate candidates; it does not prove an identical SKU, a factory relationship or that photographed accessories are included.
Materially updated . Editorial checklist; no live supplier offer is asserted.

Use this when you have a product photo but still need a measurable requirement. Keep visible features in one column and dimensions, materials or performance supplied by the buyer in another.
Use this to prepare requirements and evidence questions. It does not contact suppliers, obtain a formal quotation, certify a factory or approve a substitute.
Minimum buyer brief
Image crop or description; visible-feature ledger; quantity; must-match list; unresolved unseen facts.
| Field | Buyer input | Evidence check | Reject or unknown |
|---|---|---|---|
| visible main product | Name the pictured main object and any accessory separately. | Visible silhouette or labeled feature only; do not infer hidden construction. | Accessory-only or different main object is a mismatch. |
| quantity and unit | Positive integer and pieces/sets/boxes as supplied by buyer. | Check whether an offer counts the same complete object. | Unknown units cannot be converted or accepted. |
| buyer must-match | Buyer supplies material, dimension or model that cannot change. | Keep each explicit condition beside a scoped source. | Image inference cannot become an unstated hard requirement. |
| permitted substitution | EXACT_ONLY or a buyer-permitted alternative under the existing input schema. | Preserve the original requirement and permission. | Do not accept a merely similar item when alternatives are prohibited. |
| unseen dimensions/material | List the dimension/material that a photo cannot establish. | Ask for drawing, measurement or model-scoped document. | Omission stays UNKNOWN; no visual claim of exactness. |
Exclude or resolve
Reject inferred material as a buyer requirement; hold exact-size claims without a stated measurement; exclude accessories unless explicitly in the supported scope.
Questions to copy into a supplier enquiry
Which pictured item is the main product? Which features must remain exact? What measurement or document resolves the unseen field?
Keep quantity and price on the same basis
Keep currency, original unit, requested quantity, SKU, quantity tier and observation date together. A listing is dated commercial evidence; a supplier-confirmed quotation is a separate response for your order. Unknown pack conversion, MOQ waiver, inventory, freight or tax stays unknown.
Read evidence without upgrading it
BUYER_STATED is explicit buyer input. SOURCE_OBSERVED records a dated source; DERIVED labels an interpretation. OBSERVED does not mean SUPPLIER_CONFIRMED. Missing facts stay UNKNOWN; TO_CONFIRM names the next question.
