We sit on the supply side, in Yiwu. These studies measure fields the marketplace's read-only API returns while a supplier is being evaluated, and each one says what those fields do and do not establish.

Material, standard-name and certificate fields across 1688 textile rows120 paired first-page search positions and product-detail API responses · 10 stated limitsIn a Supplymo non-random sample of 120 first-page result/detail API pairs across 12 selected English textile and garment-accessory searches on 1688, 116 detail responses returned at least one material- or composition-related structured attribute, 7 contained a monitored textile-standard name in the translated title, selling-point, attribute or certificate fields, and 8 displayed at least one certificate-field entry.
Two API-returned repurchase fields on 1688120 paired search-row and product-detail API observations · 9 stated limitsIn a Supplymo non-random sample of 120 paired first-page search rows and product-detail API responses across 12 selected English searches on 1688, search-row repurchaseRate and detail-response sellerDataInfo.repeatPurchasePercent returned different numeric values in all 120 pairs, with the detail-response value higher in all 120.
Supplymo 1688 Shelf Index — Issue 126 daily aggregate rows from one fixed 120-item panel · 10 stated limitsIn a fixed, non-random Supplymo panel of 120 1688 product-detail records observed once daily from 2026-08-06 to 2026-08-31, the composite-service median across 3,119 returned score observations was 4.5/5; 1,291 of 3,119 logistics-score observations and 500 of 3,119 after-sales-score observations were below 3.5, while 0 of 3,120 daily observations were explicitly marked offer_not_returned by the collection contract.
Repeated tokens in API-returned 1688 subjectTrans title fields120 first-page API result rows · 9 stated limitsIn a Supplymo non-random sample of 120 first-page API result rows from 12 selected English searches on 1688, 72 subjectTrans title fields repeated the same English token at least three times; all 120 returned zero CJK characters, a character-residue check that does not assess translation accuracy or fluency.
Listed MOQ and displayed price tiers across 1688 result/detail rows120 non-deduplicated result/detail rows · 10 stated limitsIn a Supplymo snapshot of 120 non-deduplicated result/detail rows from 12 selected English searches on 1688, 102 returned a listed minimum order quantity of two units or fewer and 84 returned one displayed price tier; neither field confirms checkout acceptance, a negotiated production MOQ or a final supplier quote.

How these are made

Three rules every study follows

What none of these studies can tell you is what a supplier will actually do after payment. They record what a read-only API response returned, nothing more.

Read-only, and reproducibleEvery sample is collected through the marketplace's own public API using search and detail endpoints only. No order, payment, enquiry or messaging endpoint is ever called. The sampling script is in the repository.
The evidence file is publishedEach study ships a sanitised evidence file carrying every public row, the full method and the limits. Supplier identities are excluded from public evidence. Offer IDs used transiently for detail calls are not published; seller IDs, shop names, titles and prices are not retained in these evidence files.
The limits are stated up frontThese are non-random samples taken from ranked search results on a single day. Each study says so in its own words, near the top, rather than in a footnote.
