3DX-Ray and the PAS 97:2021 mail screening and security speciﬁcation
15 November 2021
We produce both conveyor and cabinet X-ray mail screening systems. They are fully compatible with the new BSI PAS 97:2021 specification. Much of the information on this page is summarized from BSI’s publications which can be downloaded here.
The PAS 97:2021 specification helps identify and implement postal security and screening measures for any concern. All businesses and non-commercial concerns still need to send and receive mail, packages and other items.
The greater the potential threat, the greater the necessary commitment of resource and effort to mail screening. PAS 97 achieves this through mail hazards in two categories and various screening levels.
The categories are “discrete threat objects and bulk materials” and “white powders”

Discrete threat objects and bulk materials
This covers bulk quantities of hazardous materials and these are usually clearly discernible when mail is X-rayed. It includes:
- explosive and incendiary devices (improvised or of commercial or military origin);
- firearms and ammunition;
- blades and other sharp items, (e.g. syringe needles, broken glass);
- offensive material (e.g. faeces, urine);
- bulk chemicals – toxic, corrosive or otherwise harmful, including narcotics;
- bulk biological materials;
- bulk radiological (radioactive) materials.
This refers to chemical substances such as explosive, narcotic, biological or radiological materials. It also covers the benign materials that can be used as hoax threats. “White Powders” are not necessarily “white” or even “powders”, they can be crystalline, oily or waxy residues, or liquids.
The PSA 97 specification then details six separate levels of threat (including a level zero) and associates each of these with the level of protection it offers for both “objects” white powder” threats.
Several classes of measures are detailed in PAS 97 mainly concerning the design, construction and layout of the mail room. Personal protective measures are also covered including recommended classes for each screening level
