What are Legacy Parts?

A legacy part is a part with a date code prior to 1998. The markings on these parts may appear different when compared to parts with a more recent date code. For example the markings on an older part might not be as neat and presentable as something you might see on newer parts.

For example:

Quest Components has implemented a Legacy date beginning in 1998.

Why 1998?

Our decision to label parts produced in 1998 or prior is based on two factors.

  • The Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and their Disposal (The Basel Convention) which was adopted on 22 March 1989 and entered into force on 5 May 1992.
  • China enters the World Trade Organization (WTO) in December 11, 2001

The Basel Convention was negotiated to combat toxic trade and was adopted in 1989, in response to a public outcry following the discovery, of deposits of toxic wastes in Africa and other parts of the developing world that had been imported from abroad.

Under The Basel Convention Shipments without “prior Informed Consent” are illegal. Shipments to and from non-Parties are illegal unless there is a special agreement. Additionally the parties must ensure that hazardous and other wastes are managed and disposed of in an environmentally sound manner.

Examples of waste by the Basel Convention include:

  • Biomedical and healthcare wastes
  • Used oils
  • Used lead acid batteries
  • Persistant Organic Pollutant wastes (POPs wastes), chemicals and pesticides that persist for many years in the environment. They are transported great distances from their point of release, bioaccumulate (thus threatening humans and animals at the top of the food chain), and cause a range of health effects.
  • Polychlorinated Biphenyls (PCBs), compounds used in industry as heat exchange fluids, in electric transformers and capacitors, and as additives in paint, carbonless copy paper, sealants and plastics.
  • Thousands of chemical wastes generated by industries and other consumers.

As of December 2015, the European Union along with 183 Countries are parties to The Basel Convention. The United States signed the convention in 1990 and supports the ratification of the convention, but to date no implementing legislation has been enacted.

The United States has continued to export its hazardous e-waste to the developing world, primarily China, where e-waste recycling has become a way of life, despite its toxic effect on the people processing this waste.

On December 11, 2001 China was admitted to the WTO. This lifted the previous ban on exports by non-government owned and controlled business entities. Many believe this spawned the beginning of counterfeiting in China. The United States has become China’s largest export leading to an increase in counterfeit products entering the US.

In order to help identify counterfeit verses an older part we have labeled any part made prior to 1998 as a Legacy Part. As indicated above these may look different but this is due to techniques and technology available at the time of production and not counterfeit production.

Should you have the need to return any parts Quest has a generous 180-day return policy for parts with any functionality problems. For full details on our return policy please visit our RMA Policy.
