What is it?
Safety Data Sheets (SDS) are the essential "Guidance Documents" for chemical products, legally required Globally. They ensure that anyone handling your products, from Manufacturers to transporters to end-users, knows how to do so safely and in compliance with the law.
SDS authoring is the process of gathering technical data to create these documents according to specific regional regulations, such as EU REACH, US Hazcom and GHS. Our goal is to take the complexity of global chemical regulations and turn it into clear, compliant documentation that protects your people, your business and your clients.
What we offer
At Yordas, we combine deep scientific expertise with a human touch, ensuring your SDS are not only compliant but also practical and tailored to your specific industry needs. We help you meet regulations and make your products more sustainable.

SDS Manager and Management
Managing a growing library of Safety Data Sheets can quickly become a logistical burden. Our SDS Management service takes the weight off your regulatory team. Using our proprietary Helix platform, we provide a centralized, cloud-based repository for all your documents.
- Version Control: We ensure that only the most recent, compliant versions are available.
- SDS Notifier: allowing you to manage and monitor changes that are required to your documentation therefore always keeping you ahead of the curve.
- Accessibility: Instant, 24/7 access to your SDS ensures you meet legal requirements for workplace safety and emergency preparedness.

REACH Registration Support
If you manufacture or import chemical substances into the EU or UK in quantities of one tonne or more per year, REACH registration is a mandatory "ticket to play." Our experts guide you through this complex technical hurdle.
- Lead Registrant & Only Representative (OR) Services: For non-European companies, we can act as your OR, taking on the legal responsibility for your substances in the EU market.

Product Labelling
A Safety Data Sheet is only half the battle; your physical packaging must also communicate hazards clearly. Our Product Labelling service ensures that your physical labels are a perfect reflection of your SDS and fully compliant with CLP and GHS standards, along with additional regional requirements (i.e US consumer labelling).
- Label Design and Layout: We provide the exact phrasing, pictograms, and signal words required for your specific container sizes.
- Multilingual Support: We manage the complexity of "booklet" labels or multi-language layouts for products sold in multiple jurisdictions.

Poison Centre Notifications (PCN)
For hazardous mixtures placed on the EU market, a simple SDS is no longer enough. You must submit a PCN to the European Chemicals Agency (ECHA) to assist emergency responders.
- UFI Generation: We generate and manage your Unique Formula Identifiers (UFI) that must appear on your product labels.
- Legal Entity Services: For non-European companies we can act as your legal entity to submit dossiers on your behalf.
- Dossier Submission: Our team prepares the specialized XML files required for the ECHA submission portal.
- Confidentiality Management: We help you navigate the balance between protecting your trade secrets (proprietary formulas) and fulfilling your mandatory disclosure
