The certificates that matter most are ISO 9001 for quality management, REACH status if you import into the EU, and kosher or halal certificates if your customers ask for them. Environmental and safety certificates such as ISO 14001 and ISO 45001 help but are rarely required.
Every certificate has a scope, a site and a validity date. A certificate for the wrong site or product gives you no assurance.
ISO 9001, 14001 and 45001
ISO 9001 shows the plant has a documented quality system with batch records, calibration and complaint handling. It does not prove the product is good. ISO 14001 covers environmental management and ISO 45001 covers health and safety.
Check that the certificate names the plant you will buy from and covers the product. Check the certification body is accredited and that the certificate is listed as valid. Our guide on manufacturer certifications explains how.
REACH
If you import a castor derivative into the EU, it may need to be registered under REACH. Some natural substances, such as castor oil that has not been chemically modified, may fall under exemptions. Chemically modified derivatives such as HCO, 12-HSA and sebacic acid generally do not.
The legal duty falls on the EU importer, unless the non-EU manufacturer appoints an Only Representative who registers for it. Ask the plant whether it has an Only Representative and whether your volume is covered. Confirm your own position with your REACH adviser or national helpdesk. See who is responsible for REACH registration. UK REACH is a separate regime for Great Britain.
Kosher, halal and other documents
Cosmetic, food-contact and some industrial buyers need kosher or halal certificates. Make sure the certifying agency is one your customer accepts, because acceptance differs between markets. Check that the certificate lists the exact product and site and is still valid.
- A safety data sheet in your market's format and language.
- A certificate of analysis for each lot.
- Statements on allergens, GMO status, BSE/TSE and animal origin for cosmetic and food-contact uses.
- Statements on residual nickel catalyst for hydrogenated products.
- Bio-based content test reports, explained in whether castor derivatives are bio-based.
- Sustainability or social compliance certificates where your customers require them.
How to check a certificate
Ask for a copy of every certificate before you order, not after. Then check three things. First, the site address matches the plant you audited or will audit. Second, the scope names the product or product group you are buying. Third, the certificate is still valid, which you can usually confirm with the issuing body.
If a plant sends a certificate in a trading company's name, the certificate covers the trader's office, not the plant. Our guide on telling a trader from a manufacturer explains why that matters.
