Six things a buyer comes to do.
A QA or procurement buyer who lands on a supplier's site has six jobs. Here is how Denim Colourchem's site today, ROHA and this concept handle each one.
| Buyer task | Denim todaydenimcolourchem.com | ROHAroha.com | This concept |
|---|---|---|---|
| Find a range | PartlyA product menu lists the ranges; the homepage tiles are stock photos. | YesFive ranges on the homepage; the products sit on one very large page. | YesSix named ranges on one shade card, searchable by E number and filtered by shade. |
| Find a specification | PartlyA strength band of 70 to 87%, but no page per colour. | PartlyA stability block per dye, but no E numbers on synthetics and no page per product. | YesOne page per colour with the full identifier set. Tartrazine E102 is built. |
| Find a certificate | NoCertificates are named in text but none opens; the site cites ISO 9001:2008. | Partly46 open PDFs, but no TDS, SDS or certificate among them. | YesTDS, SDS, specification and certificates for each colour, open to download. |
| Request a sample | PartlyA general enquiry page only. | PartlyA contact form; a template email address was left on the site. | YesA request that asks for the colour, application and markets, plus WhatsApp. |
| Know if a colour is allowed in my market | NoGeneral compliance claims only. | NoThe Regulations page was empty on 14 Oct 2026. | YesStatus in five markets on every colour, with the Gulf first. |
| Find the Gulfood stand | NoThe latest exhibition listed is FI Europe 2017. | NoThe events listing is out of date. | YesStand R-D60, dates and a meeting request, in English and Arabic. |
Denim facts are from the 12 Oct 2026 read of denimcolourchem.com; ROHA facts from the 14 Oct 2026 benchmark. Values marked "to confirm" in the concept stay placeholders until Denim supplies them.
What a buyer sees first.
Every supplier we compared opens on a stock lifestyle photo. The concept opens on the colour itself, with its number.
The other six, on the same tasks.
| Site | Range | Specification | Certificate | Sample | Market status | Gulfood stand |
|---|---|---|---|---|---|---|
| Neelikon | Yes | Partly | Partly | Partly | Partly | No |
| Vidhi | Partly | Partly | Yes | Partly | No | No |
| Koel | Partly | No | Partly | Not rated | No | No |
| Oterra | Yes | Partly | Partly | Not rated | Partly | No |
| GNT EXBERRY | Yes | No | Not rated | Not rated | No | No |
| Sensient | Partly | No | No | Yes | No | No |
Read on 14 Oct 2026. "Not rated" means the benchmark notes do not cover that task for that site. None of the seven publishes status by market for each colour, or a Gulfood page with stand, dates and booking.
