How LUMGEX works — methodology

Last updated: 2026-05-21 · Next review: 2026-08-19

In short: LUMGEX builds the Intelligence Report against official, publicly available sources: EU regulations, European Commission guidance, national authorities in the LUMGEX-supported countries, official EU registers, and Amazon’s own published seller-facing pages. Forums, blogs, competitor pages, and outputs from generative AI tools are treated as research signals only — never as authority. The result is a roadmap of documentation areas to investigate, not a compliance verdict.

1. Official-source intake

Every Intelligence Report is built against official, publicly available sources. LUMGEX relies on:

EU legal basis — the consolidated text of EU regulations, directives, decisions, and delegated acts (for example, GPSR and sector-specific regulations).
EU official guidance — European Commission guidance documents, the Blue Guide, and official Q&A.
National authorities — government bodies and regulators in the LUMGEX-supported countries (NL, DE, FR, IT, ES, SE, PL, AT, IE, PT).
Official registers — for example, NANDO (Notified Bodies), the Safety Gate rapid alert system, and national EPR/WEEE registers.
Amazon’s own published seller-facing pages — where Amazon publicly states what it expects from sellers.

Each source is recorded with a date checked, because regulations and Amazon policies change. Sources are re-verified on a defined review cadence.

2. Source roles

Not every source carries the same weight. LUMGEX uses a small, explicit set of source roles so the evidence behind each claim is honest:

EU legal basis and national authorities support legal or regulatory statements.
Amazon’s published seller-facing pages support Amazon-specific statements.
Official registers support facts that can be verified in a database (for example, the existence of an accredited Notified Body for a given directive).
Reddit threads, forums, blogs, competitor pages, and outputs from generative AI tools (Perplexity, ChatGPT, Claude, Gemini, NotebookLM, Grok, and similar) are treated as research signals only — never as authority. They do not back a claim in the report.

LUMGEX does not ingest or reproduce the clause text of paid standards (EN, ISO, IEC, CEN, CENELEC, BS, DIN, NF, UNE, NEN, SS, PN, and similar). Where relevant, the report references the number and title of a standard and points to the EU harmonized standards list that mentions it.

3. Rulebooks and claim gates

For each product family LUMGEX supports — Electrical & electronics, radio equipment, connected radio equipment, lighting, toys, food-contact articles, personal protective equipment, textiles & apparel, and general consumer goods — there is an internal rulebook that maps regulatory areas to the documentation areas a seller should investigate.

Each claim in a report passes through claim gates:

If the claim is a legal or regulatory statement, it must be backed by EU legal basis, EU official guidance, a national authority, or an official register.
If the claim is an Amazon upload or policy statement, it must be backed by Amazon’s own published seller-facing material.
If the claim is a family-specific documentation area, it must come from the rulebook for that family, anchored to an official source.

Claims that do not satisfy the gates are not published in the report.

4. QA and fail-safe logic (high level)

The Intelligence Report passes through a layered QA process before delivery:

Out-of-scope filter. Products outside LUMGEX’s scope (for example, medicinal products) are stopped early and are not processed as if they were in scope.

Source-role check. Every cited source is checked against its declared role before it can back a claim.

Editorial-safety check. The report is screened against a forbidden-claims registry. Examples that are blocked include marketplace-prediction phrases, blanket compliance verdicts, and unverified testing or third-party assessment claims that LUMGEX has not actually performed.

Manual review for edge cases. When automated checks raise uncertainty, the report is held back from automatic delivery and reviewed internally instead of being delivered automatically.

If any step fails in a way that cannot be safely resolved, the report is held back and reviewed manually.

5. Handling uncertainty

LUMGEX errs on the side of saying “this is a documentation area to investigate” instead of guessing.

When a question requires physical inspection of the product, the report marks it as a physical-check-pending item and explains why LUMGEX (a remote, document-only service) cannot resolve it from a desk. Sellers can then perform the check themselves or engage an appropriate professional.

When a question requires legal interpretation, the report says so and points the seller toward a qualified lawyer. When it requires laboratory testing, the report says so and points the seller toward an accredited lab.

The report does not invent documents, does not invent standards, and does not invent Amazon policies.

6. What LUMGEX does not use as authority

To be explicit:

LUMGEX does not cite outputs from generative AI tools (Perplexity, ChatGPT, Claude, Gemini, NotebookLM, Grok, and similar) as authority. If an LLM is used internally to draft, every claim is re-verified against an official source before it appears in a report.
LUMGEX does not cite Reddit, Quora, LinkedIn, Trustpilot, or seller-forum posts (by non-Amazon users) as authority.
LUMGEX does not cite competitor or agency marketing pages as authority.
LUMGEX does not reproduce the clause text of paid standards. Where a standard is relevant, the report names it (number and title) and points to the public EU harmonized standards listing.

7. When to consult a lawyer, lab, Notified Body, or Responsible Person

The Intelligence Report points sellers to qualified professionals whenever a question is outside LUMGEX’s scope:

Lawyer — for legal advice in your jurisdiction, contract questions, liability, or disputes.
Accredited laboratory — for product testing (electrical safety, EMC, radio, chemical, mechanical, toy safety, food contact, and similar).
Notified Body — for formal conformity assessment under an EU directive that requires it.
Responsible Person provider — for EU representation when a non-EU seller needs an EU-based Responsible Person under GPSR or sector law.
Tax professional — for VAT, OSS/IOSS, fiscal representation, and similar tax matters.

LUMGEX does not perform any of these activities itself.

8. Why LUMGEX is a roadmap, not a verdict

The compliance landscape for Amazon EU sellers spans EU law, national implementation, sector-specific rules, harmonized standards, Amazon’s own evolving policies, and the practical reality of each ASIN. A single report cannot, and should not, pretend to be a compliance verdict on a product LUMGEX has not physically seen, in a regulatory environment that changes.

What a single report can do is give a seller a clear, source-backed map of where to look next: what to request, what to verify, what to prepare, what to translate, what to label, what to consider uploading, and where to seek qualified professional help.

That is what the LUMGEX Intelligence Report is. It is a roadmap.
