Data Provenance & Verification

Where every dataset in this portal came from, when it was pulled, how it was cleaned, and the certificate identity each network source was verified against.

What this page is — and is not

  • This page is maintained by marketsync global ltd to document where the data in this portal comes from and how it was processed.
  • It records the maintainer's own observations. It is not a certification, an audit result, or an endorsement by Export Bangladesh, Bangladesh Bank, BANGLACRAFT, or BAPA.
  • Certificate fingerprints are recorded to make a later re-pull comparable against the same host identity. A certificate rotates routinely; a changed fingerprint on its own is not evidence of compromise.
  • Every dataset here is a point-in-time snapshot shipped as static content. It is not a live feed, and figures should be confirmed against the originating source before commercial reliance.

Certificate self-check

Re-derives the leaf fingerprint and SPKI pin for exportbangladesh.gov.bd from four independent evidence sources and diffs each against the values stored in this repository. Every row states what it proves and what it does not; “inconclusive” is a first-class outcome and is never reported as a match.

Only the prefix 00 04 F8 27 was legible in the screenshot, so the full point is not stored here — the offline derivation is inconclusive until you paste it.

Endpoint

n/a — no upstream endpoint

Cleaning applied

  • One unique illustration per catalogue-less exporter (196 images) — no two exporters render the same picture.
  • Each exporter's tile subject is inferred from its own registered name where the name names a product line, otherwise from its registered industry.
  • Images are CDN-hosted through asset pointers; no binaries are committed and no model runs at request time.
  • A shared set of three illustrations per industry is retained as a last-resort fallback for records outside the generated set.
  • Used only where the upstream record has no photograph, or where the exporter publishes no catalogue at all.
  • No HS code, SKU, description, price, capacity or certification is synthesised — generated tiles carry no trade fields.

Caveats

  • These images are illustrative of the industry, not photographs of the exporter's goods, and are labelled that way everywhere they render.
  • They are excluded from every upstream coverage figure on this page; the 269-product count remains source-only.
  • A generated tile must not be used as evidence that an exporter manufactures a depicted item.
  • Name-derived subjects are an inference from a company name, not a product filing — treat a mismatch as expected, not as a data error.

Withheld from the bundle

  • Nothing withheld — the source carried no personal contact fields.

Endpoint

https://api.exportbangladesh.gov.bd/api/v1/public/seller/{id}/products

Cleaning applied

  • Product names trimmed and de-escaped; empty descriptions normalised to null.
  • Relative media paths resolved against the registry's own media host (ec4-jmedia.s3.ap-southeast-1.amazonaws.com), confirmed by HTTP 200 on sampled thumbnails.
  • HS codes and SKUs kept verbatim as published — neither is validated against the HS nomenclature.
  • Duplicate product rows within one exporter collapsed on name + thumbnail.

Caveats

  • 70 of the 101 probed canonical exporters publish products (269 items); 97 publish a logo. Absence of a catalogue is an upstream publishing gap, not evidence the exporter has no range.
  • Images are hot-linked to the registry's media host, so a tile can break if upstream deletes an object; broken and missing images render an explicit placeholder rather than a substituted photograph.
  • No MOQ, pricing, capacity or certification data is published on this endpoint.

Cleaning applied

  • Placeholder rows rejected, including "Noel Anderson Inc" still live in the upstream leather sector.
  • Duplicate companies collapsed, keeping the richer record.
  • Company-name typo variants matched across sources ("Matadoor"/"Matador", "NAOGOAN"/"Naogaon", "Paragon Plant"/"Paragon Plast").
  • "N/A" and empty strings normalised to null; bare numeric business volumes flagged as unit-unverified.
  • Nonsense founding years dropped (one record reported yearOfEst 10000).

Caveats

  • 100 of 115 fixture records matched a canonical upstream exporter id; 15 appeared in the original dump but not in this pull and are shown as unconfirmed rather than deleted.
  • The upstream portal renders its sector list twice in a single document, which is the source of the repeated category blocks seen in the original paste.

Withheld from the bundle

  • Nothing withheld — the source carried no personal contact fields.

Caveats

  • Representative names are printed in the source as business contacts and are retained; treat them as business, not personal, contact data.

Identity verification, registry reconciliation and certificate-level provenance are three different claims.
