Sector certificate map: which certificate goes where on the site.
Which certificate belongs on a certified manufacturer’s website depends on the sector: IATF 16949 in automotive, registration numbers in chemicals, BRCGS, IFS or FSSC 22000 in food, a declaration of performance in construction products. But the shape of the mistakes is the same across all thirteen sectors: presenting a declaration as a certificate, using a mark in the wrong place, turning a site certificate into a product claim, and leaving an expired certificate up.
This page is the cluster’s sector map: for each sector it collects in one table the main certificates and registrations, what should not be written on the site, what changed in 2026 and where a buyer verifies the certificate. Each row’s detail is in that sector’s own guide; how a certificate generally belongs on a website is covered in the certified manufacturer website guide.
How much of exports do these sectors carry?
The sectors this cluster covers account for about 89% of sector-based exports registered with the Turkish Exporters Assembly (TİM) in 2025 (our calculation from the TİM table). The shares are not of Turkey’s total exports but of sector-based exports registered with TİM: TİM’s annual table links the 237.37 billion dollars of registered exports to the Ministry of Trade’s official total of 273.43 billion dollars by adding exports exempt from exporters' association registration and the bonded warehouse and free zone difference (36.06 billion dollars).

Summed by guide, the order is: automotive 17.5%; chemicals 13.5%; metals 12.6% (steel plus ferrous and non-ferrous metals); textiles 11.1% (apparel and clothing plus textiles and raw materials); electrical and electronics with air conditioning 10.6%. The totals are our calculation from the shares in the table. Machinery and parts, at 4.7%, is the largest sector with no website at all in our own sample; that is why it is measured with a separate sample.

Medical devices, cosmetics and packaging do not appear as separate rows in TİM’s sector table; we took them into the cluster with their own guides because their certification regimes are different. The share column in the table is each row’s proportion of the 237.37-billion-dollar total.
Which certificate belongs where on the site in which sector?
The table below summarizes each sector’s certificate map. The “should not be written on the site” column shows a phrase or use that runs against that sector’s rules, and the “2026” column the year’s dated change in that sector.

Reading the table one row at a time: in the chemicals row there is a registration, not a certificate. Under REACH, the European Chemicals Agency issues a registration number after a completeness check but does not assess the quality of the data; a manufacturer outside the EU can appoint one only representative per substance. So a “REACH certificate” is not a certificate claim but a misnomer. For its Turkish counterpart KKDİK, the deadline for the first registration is December 31, 2026.
Which mistakes repeat across the thirteen sectors?
Putting the sectors' rules side by side shows that four mistakes can be made in the same way in every sector. The rule behind each is different, but the fix is the same: write the certificate under its own name, with its own scope and in its own place.
- Presenting a declaration or registration as a “certificate”. CE is the manufacturer’s own declaration, and voluntary “CE certificates” have no legal standing; a REACH registration number does not approve the quality of the data; a CPNP notification does not mean the product meets all requirements.
- Using a logo where it is not allowed. The IATF logo may appear only as printed on the certificate; the IFS and GLOBALG.A.P. logos do not go on consumer packaging; FSC marks may not be used in a company name or domain name.
- Turning a site certificate into a product claim. An LWG certificate belongs to the site, not the product; a scope certificate says the site can produce certified goods, but only a transaction certificate says a specific shipment is certified.
- Leaving the claim up when the certificate ends. BRCGS requires the logo and all claims to come down when the certificate ends, and for IATF 16949 the certification bodies require every reference, including on the website, to be removed.
The fix for the four mistakes works the same way in every sector: the certificate’s name is written as on the certificate, who issued it and what it covers are put next to it, and an expired certificate comes off the site the same day. A certificate record that does this consistently for every certificate gives the buyer correct information even if they do not know your sector’s rules.
How are the sectors distributed in the exporter sample?
Our own measurement sample is also a cross-section of this distribution. On November 10, 2026, we matched the 85 own websites in four provinces from the “Exporter websites 2026” measurement with TİM’s sector table: 15 sites from cereals and pulses, 12 from automotive, 8 each from steel and textiles, 7 from apparel; none from machinery. The cluster’s measurement articles count the certificate pages, page builder traces and neglect signals of this sample.
How does the product page change from sector to sector?
Where the certificate connects to the product changes by sector, and in some sectors this connection is a rule. For an energy-labeled electronic product, the QR code on the label leads to the model’s EPREL page; the product page should show the same record. For a construction product, the declaration of performance and conformity may be published on the site, but only if it is unalterable, readable by humans and machines, downloadable and linked to the product-type code. In cosmetics, the product has a responsible person established in the EU. And for every product sold online to EU consumers, the manufacturer’s name and address, the responsible person if outside the EU, and warnings appear on the offer. The details of this last rule are in the product page for online sales to EU consumers guide.
What does a sector guide add?
Each sector guide answers the same seven questions with that sector’s certificates: which certificate the buyer asks for, how the certificate is shown on the site, what should not be written on the site, what changed in 2026, how the buyer verifies the certificate, how the product page and machine layer are built, and a short checklist. The table is an introduction; in a sector, the guide itself makes the call.
If your sector is not in the table, the general rule applies: how to build the certificate record is in the certified manufacturer website guide, and how the buyer verifies a certificate in the certificate verification guide.
How to test it: for each certificate on your site, open your sector’s row in the table above and search your own site for the phrase in the “should not be written on the site” column. Every result is a line to fix.
The information here is not legal advice; confirm the current requirement in your sector from official sources and your certification body’s rules.
Let’s put your sector’s certificate map side by side with your site as it is today, and show in writing which certificate is missing or wrong where.
For a site that shows your certificates as a record buyers can verify, B2B website builds and measures the certificate page, the product scope and the path to a quote together.
FREQUENTLY ASKED QUESTIONS
My sector’s certificates are not in the table; what should I do?
The table collects the main certificates of the sectors this cluster covers. If your certificate is not here, the rule is the same: write the certificate’s standard and edition, scope, number, issuing body and where to verify it; check the program’s own mark rules.
Why are the TİM shares not based on the official export total?
TİM’s sector table shows exports registered with exporters' associations; exports exempt from association registration and the bonded warehouse and free zone difference do not enter the table. So the shares are of the 237.37 billion dollars of registered exports; the official total is 273.43 billion dollars.
If we produce in several sectors, how should certificates be separated on the site?
By product group. Each product page links to the certificate covering its group; the certificate page lists the certificates with their scopes. In a multi-site company, which certificate covers which site is written separately.
