Abstract: A method of manufacturing a component for an aerosol-generating article including a taggant is provided, the method including the steps of: applying the taggant to the component; detecting an amount of the taggant that the component comprises; determining whether the detected amount of the taggant is less than a first-predetermined amount; and rejecting the component when the detected amount of the taggant is less than the first-predetermined amount. An apparatus for manufacturing a component for an aerosol-generating article including a taggant is also provided. A kit of parts is also provided.

Abstract: A kit comprising: an aerosol generating article (2) comprising a combustible heat source (4) and an aerosol-forming substrate (10); and a retainer (300) for the aerosol generating article, the retainer comprising: a tubular body (302) having a partially-closed first end (304a) and an open second end (304b), wherein the body defines a longitudinal passage (305) extending between the first end and the second end and wherein the body comprises: a first portion (307) proximate the first end comprising a plurality of openings (306); and a second portion (309) between the first portion and the second end, wherein the body is configured to at least partially receive the aerosol-generating article in the passage such that the first portion of the body surrounds the combustible heat source of the aerosol-generating article, wherein the first end and the first portion of the body are configured such that at least about 80 percent of the exposed surface area of the combustible heat source of the aerosol-generating artic

Abstract: A multi-segment component for an aerosol-generating article is provided, the multi-segment component including: a combustible heat source; an aerosol-forming substrate downstream of the combustible heat source; and a wrapper circumscribing a rear portion of the combustible heat source and at least a front portion of the aerosol-forming substrate, a front portion of the combustible heat source extending beyond the wrapper so that the front portion of the combustible heat source is exposed during use; and an intumescent coating on all or part of the front portion of the combustible heat source, the intumescent coating being configured to form a heat insulating layer on the front portion of the combustible heat source in response to heating by the combustible heat source.
