An importer should ask each supplier for the manufacturer's declaration of conformity, the test reports behind it, the technical file (or confirmation it exists and can be produced), evidence of the CE or UKCA marking, instructions and safety information, and traceable product identifiers. AI can summarise those documents and flag gaps, but a person decides whether a product may be sold.
A key point catches many first-time importers out: once you place the product on the market under your name, you share responsibility for its compliance. "The factory said it was certified" is not a defence if the certificate belongs to a different model. What AI does well here is reading ten supplier files in an hour and producing a table of what is present, what is stale and what does not match. What it cannot do is decide that a test report is adequate, which is a judgement for you or a compliance adviser. The checklist is a working tool, not legal sign-off.
The ten documents, and what to look for in each
The list below suits most products that carry CE marking, such as electrical goods, machinery, toys, personal protective equipment and radio devices. The exact requirements depend on the product category and the rules that apply to it, so treat this as the common core and let your adviser add to it.
| # | Document | What to look for |
|---|---|---|
| 1 | Declaration of conformity | Names the manufacturer, the exact product and model, the rules and standards applied, a date, and a signature; matches the product you are buying |
| 2 | Test reports | Name the same model; cite the standards the declaration lists; dated and signed by a named lab; show a result |
| 3 | Technical file or its index | At least a contents list proving it exists and can be handed over on request; includes design, risk assessment and test evidence |
| 4 | Risk assessment | Product-specific, not a generic template; covers intended use and foreseeable misuse |
| 5 | Marking proof | Photos of the CE (or UKCA) mark on the product or packaging, legible and permanent; notified body number if one was used |
| 6 | Labelling data | Type, batch or serial number; manufacturer's name and address; your own importer name and address on the product, packaging or accompanying document |
| 7 | Instructions and safety information | Present in the language of the market you sell in; warnings match the risk assessment |
| 8 | Certificates, where required | Notified body or approved-body certificate with a valid date, for products whose rules demand third-party assessment |
| 9 | Substances and materials evidence | Declarations or test reports for restricted substances where relevant to the product (for example electronics or children's items) |
| 10 | Traceability record | Which shipment, which order, which production lot, mapped to the documents above |
The official guidance on using the UKCA marking (last updated August 2026 when checked) says CE marking continues to be recognised alongside or in place of UKCA, with no end date for CE given on that page, and that importers must put their name, trade name or trademark and postal address on the product, or on the packaging where the product is too small and the rules allow it. On the EU side, the Commission's business guidance says a copy of the most recent declaration must be kept for 10 years after the product is placed on the market, and product directives such as the Low Voltage Directive give importers that same 10-year duty, plus making sure the technical documentation can be handed to authorities on request. Check the rules for your own product category before you rely on either summary, since the detail varies by product.
A worked example: an importer of LED video lights
Take a small importer who brings in LED video lights from a factory and sells them through its own online shop (all figures and details illustrative). The first order is 400 units of one model. The supplier has sent a folder of eleven files by email. The importer's job is to find out what is there and what is not, before the container ships.
The folder contains: a declaration of conformity as a PDF; two test reports (one on electrical safety, one on electromagnetic compatibility); a scan of a factory ISO 9001 certificate; a user manual in English; photographs of the product; a packing list; a spreadsheet of specifications; and three files with names in the supplier's own language. Nobody on the importer's team reads it, and the declaration has no model number on it, only a product family name.
The prompt:
I am an importer of LED video lights. The attached files came from my supplier for product model "VL-200". I need to know what I hold before I place this product on the market.
Task:
1. For each file, state in one line: what it is, its date, the model it names, and the standards or rules it cites.
2. Translate any non-English file and treat the translation as unreliable: flag every number and model code you are not certain of.
3. Then fill in this table for the ten documents: DoC, test reports, technical file, risk assessment, marking proof, labelling data, instructions, certificates, substances evidence, traceability. For each: PRESENT, PARTIAL, MISSING, or CANNOT TELL, with the reason in a few words.
4. List every inconsistency between documents (model names, dates, manufacturer name, standards cited).
5. Do not say whether the product is compliant or safe. Do not invent documents.
A realistic reply (illustrative) would produce a table like this:
| Item | Status | Reason |
|---|---|---|
| Declaration of conformity | PARTIAL | Names "VL series", not VL-200; no signature date; cites two standards |
| Test reports | PARTIAL | Electrical safety report names VL-200; EMC report names VL-150 |
| Technical file | MISSING | No file or index supplied |
| Risk assessment | MISSING | None found |
| Marking proof | PARTIAL | Photo shows a CE mark on the rating label; legibility cannot be confirmed from a small image |
| Labelling data | PARTIAL | Manufacturer address present; no importer details yet; no batch or serial format given |
| Instructions | PRESENT | English manual; warnings not compared with a risk assessment |
| Certificates | CANNOT TELL | Only a quality-management certificate, which is not product conformity evidence |
| Substances evidence | MISSING | None found |
| Traceability | MISSING | No lot numbering scheme supplied |
That table is the useful product of an hour's work. It turns "the supplier sent a lot of files" into a list of precise requests. The importer then sends the supplier one email asking for: a declaration naming VL-200 with a date and signature; the EMC test report for VL-200, not VL-150; the technical file index and the risk assessment; substances evidence; and the batch-numbering scheme. A person should read the translated files and the two reports in particular: AI translation of technical documents is a starting point only, and the VL-150 versus VL-200 mismatch is the type of thing that matters most and is also easy to overlook in a long file.
What to fix in that first AI pass
Two corrections a careful reader would make. First, "CE mark present" in the photo does not mean the mark meets the rules on size, form and permanence, so the importer should ask for a close-up of the rating label and, ideally, a sample unit. Second, the AI wrote "cites two standards" without saying whether those are the right standards for this product. That judgement belongs to someone who knows which standards are harmonised for lighting equipment, so the importer notes it as an open question for an adviser or a test lab rather than assuming it.

Stage 1: Request the documents with a precise email
Do not ask a supplier for "all the compliance documents". They will send whatever is easiest. Ask for the ten items by name, for the exact model. This prompt turns your gap table into a request:
Write a polite, firm email to a supplier based on the gap table below. List each missing or partial item as a numbered request, naming the exact model (VL-200) and what a correct document must show (for example "a declaration naming the model, dated and signed"). Ask for a reply with all items by [date]. State plainly that we cannot ship or sell the product until we hold these documents. British English, under 220 words. Use [supplier contact] and [your name] as placeholders.
GAP TABLE: [paste]
Stage 2: Summarise a test report in plain words
Test reports are long. A summary prompt helps you decide whether to read the whole thing, and what to ask a lab or adviser:
Summarise this test report in under 200 words for a non-technical reader. State: the lab name, the report date, the exact model and serial or sample identifier tested, the standards tested against, and the overall result. List any test marked failed, not applicable or "not tested". Then list three questions I should ask about this report. Do not assess whether the report is adequate.
An illustrative result: a report dated two years ago, naming the model, citing the right standard family, with one test marked "N/A" for a feature your product does have. The third question the AI suggests, "Is the N/A justified for the version I am importing?", is the sort a person would otherwise miss.
Stage 3: Cross-check names, dates and addresses
Compare the manufacturer's name, address, model number, and date across these documents and list every difference, however small, in a table (document, field, value). Include differences in spelling, punctuation and company suffix. Do not say which is correct.
A frequent finding is that the declaration names a trading company while the test report names a factory with a different name and address. That can be perfectly normal, since many products are made by one firm and sold by another, but it should be written down and explained, and the declaration should name whoever takes responsibility as manufacturer.
Four more cases, in different businesses
A café buying an espresso grinder. The owner imports directly to save money. The supplier's declaration is real, but covers a 110-volt model and the grinder shipped is the 230-volt one. AI flags nothing, because the two model codes differ only by a suffix and both are in the file. The cross-check prompt, run on model codes only, catches it: "VM-600" versus "VM-600E". The lesson: ask for a table of every code in each document, not a summary.
A dog groomer importing a dryer. The unit is a heater with a motor, and so falls under several sets of rules. The supplier sends one declaration citing one set. The checklist prompt returns "CANNOT TELL" for the radio and substances items because no document mentions them. The groomer takes that line, not the AI's guess, to an adviser who confirms which sets apply.
A driving school buying dash cameras for its fleet. These are used by the business rather than resold, so some duties differ, but the school still wants to know the devices are legitimate. A short run of the checklist shows a declaration but no test reports for the wireless module. The school decides to buy from a seller that can supply them, which costs a little more and removes the question.
A photography studio importing reflectors and stands to sell in its online shop. Simple products, little risk. The checklist reveals that the supplier has no documents at all and says none are needed. That might be true for some product types, but the studio's adviser confirms that stands sold to consumers still fall under general product-safety duties even where no CE marking applies, so the studio still needs a risk assessment, its own name and address on the product, and a way to trace each batch. "No document needed" is a claim to verify, not a conclusion to accept.
Reading a declaration of conformity line by line
The declaration is the document everything else hangs from, so it deserves a slower read than a summary prompt gives it. A declaration normally carries the following parts, and each one is a check:
- Who is declaring. The manufacturer's name and postal address. If the name differs from the factory on the test report, find out why.
- What is covered. The product, type, batch or serial identification. "VL series" covers a family and may be acceptable only if the test evidence covers each member, so ask.
- Which rules. The legislation the product is declared against. A product with a motor, a radio and a power supply may fall under several; a declaration that lists one is a prompt to ask about the rest.
- Which standards. The standards used, with their year or edition. An edition that has been withdrawn is a flag, and AI can list the editions it sees for you to check against the current official lists.
- Who assessed it. Where a third-party body was involved, its name and number and the certificate reference.
- Signature, place and date. A date that falls after the shipment date, or none at all, is a flag.
Here is a filled-in extraction for the video-light example (illustrative), with the questions it raises:
Declarer: [factory name], [address in the supplier's country]
Product named: "LED panel light VL series" -> Which models? Is VL-200 included?
Rules cited: electrical safety; electromagnetic compatibility -> Any radio control or app? If so, another set may apply
Standards cited: [two standards, editions 2014 and 2017] -> Are those the current editions?
Notified body: none stated -> Is that correct for this product type?
Signed: name and title present, no date -> Ask for a dated, signed copy
Matches test report manufacturer name: NO (report names a different company) -> Ask for the relationship
The arrows are the AI's questions, and a person turns each into either an answer from the supplier or a question for an adviser. A prompt that produces this layout: "Extract the six parts of this declaration into the layout below, and after each, write the question a careful importer would ask. Do not answer the questions."
A rule for holding stock back
Decide in advance what blocks sale, or the decision will be made under pressure when stock has already landed. A workable rule for a small importer: no product goes on sale until every item in the table is PRESENT, or a named person has accepted in writing why an item is PARTIAL or not applicable and when it will be completed. Three items are not negotiable for most products: a declaration that names the model, a test report that names the model, and your own name and address on the product or its packaging. A sensible fallback if a shipment arrives with gaps is to quarantine it in the warehouse, not to sell "just the first batch". Quarantined stock costs storage; a product withdrawn after sale costs refunds, replacement and possibly an authority's attention.
What AI cannot check for you
- Whether the right rules were applied. A document can be perfectly consistent and cite the wrong standard for the product.
- Whether the lab is competent. A report on letterhead is not proof the lab was accredited for those tests.
- Whether the sample was representative. The report covers the sample tested; your shipment is another matter. This is why a pre-shipment sample check, or a third-party inspection, is a standard part of sourcing.
- Whether a document is genuine. Forged and recycled certificates exist. Ask for certificate numbers you can check with the issuing body, where that body offers a lookup.
- Whether your product needs a notified body. That depends on the product type and the risk category.
For all of these, ask for the supplier's evidence, then ask a compliance adviser or a test lab. A short paid review of one product's file before the first order costs far less than a recall or a customs hold. The cost belongs in your landed cost model as a line of its own.
Turning the checklist into a repeatable file
Set up one folder per model, with the ten documents named the same way each time (for example "VL-200 - DoC - 2026-09-14.pdf"), and a single sheet recording: the document, the date received, the date it expires or needs review, who checked it, and notes. Then use the AI check as a gate at three points:
- Before the first order, when you can still walk away from a supplier who cannot provide the documents.
- Before shipment, after the samples or pre-shipment inspection results arrive.
- On any change: new model, new factory, new component supplier, or a change in the rules. Repeat the cross-check.
Feeding the result into a supplier scorecard turns documents into a purchasing signal: suppliers who send a complete, consistent pack on the first request are generally easier to work with, and those who send nothing at all rarely improve. Diary the review dates too, since a certificate that was valid in March may lapse before the next order; the compliance calendar tutorial shows a simple way to do it.
Handling confidential supplier files
Supplier files often contain drawings, bills of materials and pricing the supplier regards as confidential. Check your agreement before pasting them into any tool. Where in doubt, redact prices and drawings, or paste only the pages the check needs, such as the declaration and the front pages of the test reports. Business plans of the major chat assistants do not train on your content by default, according to their own pages, but a contractual duty to the supplier applies whatever the vendor's training settings say.
How to tell the check is doing its job
After the first three products, look at your records for these signs. The gap table is changing the way you buy: suppliers are asked for specific documents up front, and you have turned down at least one that could not provide them. The mismatches AI found were confirmed by a person as real, not as translation noise. And your adviser's time is spent on the open questions, not on sorting a folder. If instead the AI table is simply being filed away unread, the process has become theatre. Put one name against each open item and a date by which it will be closed, and do not release stock to sale until they are.
None of this makes a product compliant by itself. It makes the question visible earlier, while a missing document is still a supplier email, not a seized shipment. For a first-time importer, that shift is the single most valuable thing the checklist does.
Importer questions about supplier documents and AI
Is a CE mark on the product proof that it complies?
No. The mark is the manufacturer's own claim that the product meets the rules, so it is only as good as the declaration and test evidence behind it. An importer who places the product on the market takes on duties to check that the evidence exists, even if a supplier insists the product is fine.
How long should I keep the supplier documents?
For many CE-marked goods, such as electrical equipment, the product directive tells importers to keep a copy of the declaration of conformity for 10 years after the product is placed on the market and to make sure the technical documentation can be produced for authorities on request. Check the rules for your product type, since the period is set product by product.
Can AI read a test report in another language?
It can translate and summarise one, which helps you see the product name, standard, date and pass or fail result. A person must still confirm the report relates to your exact product and model, because translation errors on numbers and model codes are easy to miss.
Does a test report from the factory's own lab count?
Possibly, but treat it with caution. What matters is whether the lab is competent and independent enough for the rules that apply, and whether the report names your model and the right standard. A compliance adviser or the market surveillance guidance for your product type can tell you what is acceptable.
