Quality

Quality and evidence

This page names the standards we supply to and the inspections we commission. It does not describe a certification held by the company itself. We disclose which approval exists in a given case before the contract is concluded.

Management standards

How organisation, environment and occupational safety are governed

ISO 9001

Quality management

Governs how a company organises processes, responsibilities and improvement so that a delivery repeatably achieves the same quality as the previous one.

ISO 14001

Environmental management

Governs the handling of environmental impacts, resource use and waste, and compliance with environmental requirements along the supply chain.

ISO 45001

Occupational health and safety management

Governs how hazards at the workplace are identified and controlled, from loading through to the terminal.

Labelling

REACH and GHS/CLP

REACH

The EU chemicals regulation on the registration, evaluation, authorisation and restriction of chemicals. Anyone who imports a substance into the EU or places it on the market there must register it above a quantity threshold. This also applies to imported petrochemical goods and additives.

REACH governs the substance itself and not the individual delivery. In the shipping documents it shows up in practice as the safety data sheet and the labelling.

GHS/CLP

The Globally Harmonized System for the classification and labelling of chemicals sets pictograms, signal words and H and P statements on the label. CLP is the legally binding implementation of GHS in the EU.

Labelling and safety data sheet belong together: the label shows the short form of the hazard, the data sheet the complete handling instructions.

16 sections, fixed order

The safety data sheet

Safety data sheet or SDS is the current term under GHS. MSDS is the older name for the same document and still appears in older paperwork. Both refer to the same format with 16 sections.

  1. Identification of the substance or mixture and of the company
  2. Hazards identification
  3. Composition and information on ingredients
  4. First-aid measures
  5. Firefighting measures
  6. Accidental release measures
  7. Handling and storage
  8. Exposure controls and personal protection
  9. Physical and chemical properties
  10. Stability and reactivity
  11. Toxicological information
  12. Ecological information
  13. Disposal considerations
  14. Transport information
  15. Regulatory information
  16. Other information

The sections always appear in this order, so a warehouse worker or a firefighter in an emergency finds the same number in the same place, whichever plant issued the sheet.

Dangerous goods and approvals

Regulations for the transport route and engine oil licence

Rule sets for dangerous goods transport and engine oil approval
Rule setScopeMeaning
IMDGSea transportInternational Maritime Dangerous Goods Code. Sets out how dangerous goods are packed, marked, documented and loaded for sea transport. The UN number and packing group determine the requirement.
ADRRoad transportEuropean Agreement concerning the International Carriage of Dangerous Goods by Road. Governs the vehicle, marking and accompanying papers for the overland leg to or from the port.
API licence (EOLCS)Engine oilsThe Engine Oil Licensing and Certification System of the American Petroleum Institute. A plant has its formulation tested in the laboratory against an API category such as SP or CK-4 and receives the right to use the API mark. The licence number can be looked up directly with the API.

A certificate of analysis is only as reliable as the company that signs it, and only as current as the batch it describes.

Independent inspection

Inspection companies and verifiability

Why the number matters

Verifiable directly with the inspector

Forged inspection reports with invented certificate numbers are a common type of fraud in this market. The number on a certificate of analysis or quantity can be verified directly with the issuing company, and should not be checked only with whoever sent the email.

Inspection company

SGS

Independent verification of quantity and quality before or during loading, commissioned on request. Certificate number directly verifiable with SGS.

Inspection company

Intertek

Independent verification of quantity and quality before or during loading, commissioned on request. Certificate number directly verifiable with Intertek.

Inspection company

Bureau Veritas

Independent verification of quantity and quality before or during loading, commissioned on request. Certificate number directly verifiable with Bureau Veritas.

Inspection company

Cotecna

Independent verification of quantity and quality before or during loading, commissioned on request. Certificate number directly verifiable with Cotecna.

What is binding

Typical value, batch analysis and contract

  1. 01Typical value (TDS)

    The technical data sheet describes what a product usually delivers, based on manufacturing experience. It states an expectation and is no commitment for a particular batch.

  2. 02Batch analysis (COA)

    The certificate of analysis gives laboratory results for the batch actually delivered, confirmed where required by an independent inspection company. It applies to that batch only.

  3. 03Contract specification

    The contract fixes the tolerance within which the batch analysis may deviate from the typical value. A claim can only be based on the contract, never on the data sheet.
