Quarterly Survey of Leather


The survey investigates information on the quantity of raw hides of bovine animals acquired and tanned, having as collection unit the establishments dedicated to this activity (tannery) and that purchases, annually, 5 000 or more whole units of bovine raw hide.

The Quarterly Survey of Leather began in 1997 and derived from the Annual Survey of Leather, which was reformulated and changed its name and periodicity, as well as the composition of its list of informants. In 1997 and 1998, the same variables were investigated, but from the first quarter of 1999 on, the survey also collected information on the amount of raw hide of bovine animals received from third parties for tanning and the quantity of imported leather. It stopped collecting information on tanning of goatskin, sheep and other species. As of 2012, information on imported leather ceased to be part of the survey, since it was restricted to two Federation Units and occurred in insignificant volume. More recently, in 2014, the on-line questionnaire was introduced, and the informant was given the option of data completion on the Internet.

The survey provides information on the amount of bovine whole hides, as follows: acquired by the tannery, according to the origin (slaughterhouse cooling rooms, municipal slaughterhouses, intermediaries such as salters, other tanneries etc.); received from third parties for tanning in the establishment: received from third parties to provide tanning services; tanned, according to tanning methods (to chromium, vegetable tannin and other methods); and existing on the last day of the reference quarter (initial and final stocks). The establishments that only do the salting (salters) are not considered in the investigation.

The survey is carried out quarterly, and for each quarter of the calendar year the data are broken down month by month. Its geographic coverage is national, being conditioned to a systematically updated panel, with inclusions and exclusions of establishments due to the dynamics of this productive activity. The results are disclosed, preliminarily, to Brazil and Federation Units, with a gap of one quarter between the data collection and its disclosure. The aggregate results of the reference year are released when the results of the last quarter of the year are put out. It should be noted that the data are not definitive, and may undergo changes until the results of the first quarter of the year after the survey's reference year are disclosed.

Meeting users' demands for a sooner access to livestock information, from the first quarter of 2018 on, the First Results of the Quarterly Survey of Leather for the Brazil level have become available. They are disclosed right after the end of the reference quarter, about a month before the general disclosure.
