Volume(s): Process Chemicals
Language: English

This Standard was technically approved by the Liquid Chemicals Global Technical Committee. This edition was approved for publication by the global Audits and Reviews Subcommittee on December 23, 2013. Available at and in January 2014; originally published July 2007.


NOTICE: This Document was balloted and approved for withdrawal in 2013.


Companies, when dealing with chemical materials supplied in containers, need to control the correct use of these containers and need to verify that the materials they contain are fit for use. To that purpose, the containers need to sufficiently identify the material they contain. To allow automation of these control and verification tasks, the container’s identification data needs to be computer readable.


Various semiconductor producers, as well as their suppliers, have to this purpose defined their own identification standard. This leads to extra complexity on the suppliers’ side, and requires customers each time to negotiate the use of their own standard with each of the suppliers.


This SEMI Specification for a Bar-Code Container Identification intends to offer a clear and ready-to-use solution by standardizing the contents and layout of a bar-coded container identification.


Customers not yet using bar-code support in this context, or customers relying on supplier specific bar-coded information, can now expect that all suppliers use the same approach. This simplifies the customer’s software systems and avoids being confronted with supplier specific changes.


Customers that already have agreements with some suppliers on the use of a customer specific label can now expect that all products of all their suppliers and all products of new suppliers show the standard information, avoiding the need for additional one-to-one negotiations and avoiding implementation lead times on the supplier side.


The bar-coded identification allows suppliers and customers to automate control and verification processes in their production and warehousing/storage areas. Typical control and verification tasks that are supported by the Specification:

  • registration of volumes consumed

  • verifying remaining shelf life

  • recording incoming/outgoing storage quantities

  • verifying correct tool connectivity


The Specification is used to identify primary and secondary packages of packaged commercial materials, and primary packages (e.g., isotainer) of commercial bulk materials.


Small primary packages might not have enough surface space to allow a correct application of bar-codes. In those instances, suppliers are encouraged to look for labeling solutions that would allow the application of this SEMI Specification.
