PRODUCT PACKAGE LABELS FOR ELECTRONIC COMPONENTS
USING BAR CODE AND TWO-DIMENSIONAL SYMBOLOGIES

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62090 has been prepared by IEC technical committee 91:
Electronics assembly technology.
This second edition cancels and replaces the first edition published in 2002. This edition
constitutes a technical revision.

PRODUCT PACKAGE LABELS FOR ELECTRONIC COMPONENTS
USING BAR CODE AND TWO-DIMENSIONAL SYMBOLOGIES

1 Scope
This document applies to labels on the packaging of electronic components for automatic
handling in B2B processes. These labels use linear bar code and two-dimensional (2D)
symbols. Labels for direct product marking and shipping labels are excluded. Labels required
on the packaging of electronic components that are intended for the retail channel of
distribution in B2C processes are also excluded from this document.
Bar code and 2D symbol markings are used, in general, for automatic identification and
automatic handling of components in electronics assembly lines. Intended applications include
systems that automate the control of component packages during production, inventory and
distribution.

4 Label data content and requirements
4.1 Data elements – general
This document allows mutual agreements between the supplier and the customer to alter or
enhance any of the specifications done in this document.
The label format accommodates mandatory, optional and mutually agreed data elements.
Examples of data element short titles are given in Annex D.
This document does not supersede or replace any applicable safety or regulatory marking or
labelling requirements. This document is to be applied in addition to any other mandated
labelling requirements. The labelling requirements of this document and other documents may
be combined into one label or appear as separate labels.
Approval and conformity markings, branding elements and other information can be added
when applicable. Typically, these are not relevant for automatic processing, and therefore not
further outlined in this document.
The number included in the character count is exclusive of overhead characters such as start
and stop characters, data identifiers and any other characters required by a standard
symbology specification for properly encoded data.
All data elements encoded in a machine-readable medium shall be preceded by the
appropriate ISO/IEC 15418 or ANSI MH10.8.2 Data Identifier.

– 8 – IEC 62090:2017 © IEC 2017
The manufacturer may add any data on the label. Additional linear bar codes or data elements
in the 2D symbol shall use the appropriate data identifiers.
If the optional data specified in 4.3 are indicated on the labels, they should be used as
described below.
Any further additional data or specific formats or anything else may mutually be agreed
between the supplier and the customer. Mutual agreements between trading partners are not
restricted by this document.
Data elements where global uniqueness is relevant shall follow the ISO/IEC 15459 series'
rules, or be combined with the ISO/IEC 15459 series' compliant company ID with data
identifier “18V” and be unique within the scope in this company.
4.2 Mandatory data elements
4.2.1 Manufacturer item identification – DI “1P” and “25P”
The manufacturer-assigned item identification is mandatory.
If “1P” is used, the conformity to the ISO/IEC 15459 series is achieved by its combination with
the globally unique company ID “18V”.
4.2.2 Customer product code – DI “P”
The customer product code is the code assigned to the product by the customer, and may be
transmitted together with the order.
NOTE Customer product codes on component packages are relatively widely adopted. But when manufacturing
on stock or selling via distributors, this information is not yet known.
Adding customer information on the label is subject to a purchase agreement between the supplier and the
customer. If there is no specific purchase agreement, it is up to the manufacturer to add this information or not.
4.2.3 Manufacturer identification – DI “18V” and “21V”
The manufacturer identification shall uniquely identify the manufacturer to which the
component is traceable.
“18V” is the default manufacturer identification.
In case the manufacturer’s organizational sub unit is required, e.g. to indicate a
manufacturing location, then DI “21V” is used in addition to “18V”. In case of mutual
agreement between trading partners, “21V” can be used instead of “18V”.
In human-readable form, the manufacturer identification is the full manufacturer name or its
logo. In machine-readable form, the manufacturer identification is assigned by a recognized
body that assigns company identification according to the ISO/IEC 15459 series.
The human-readable manufacturer identification and the machine-readable manufacturer
identification are different. It is recommended that there be a 1:1 relation between human-
readable and machine-readable manufacturer identification.
4.2.4 Quantity – DI “Q” and “7Q”
The quantity shall be the quantity in the package or container to which the label is affixed.
The default unit of measure for data identifier “Q” is “EACH” or “PIECES”.

When a different unit of measure is required, as agreed between trading partners, data
identifier “7Q” shall be used with the quantity followed by two alphanumeric characters
representing the unit of measurement code defined in Annex D of ANSI MH10.8.2.
It is recommended to use the quantity with a unit of measure only if the unit is different from
“piece”.
Print only the significant digits for the human-readable quantity. Do not print leading zeros.
4.2.5 Traceability identification – DI “S” and “25S”, “1T” and “25T”
4.2.5.1 General
The traceability identification shall be assigned by the manufacturer. This category of
identification includes serial numbers and lot/batch numbers.
Traceability identification should be either a serial number (using data identifier “S” or “25S”)
or a lot/batch number (using data identifier “1T” or “25T”).
In certain circumstances, both the serial number and the lot/batch number may be shown on
the label. In this case, at least one of the two shall be encoded in a linear bar code and both
shall be included in the 2D symbol.
4.2.5.2 Serial number – DI “S” and “25S”
A serial number is a unique code assigned by the supplier to an entity for its lifetime. The
format for the serial number is to be defined by the manufacturer.
4.2.5.3 Lot/batch number – DI “1T” and “25T”
A lot/batch number is a code assigned by the supplier to identify or trace a unique group
of entities (e.g. manufacturing lot, batch, inspection lot). The format for the lot/batch number
is to be defined by the manufacturer.
4.2.6 Country of origin – DI “4L”
The country of origin shall be shown in human-readable information using the full country
name.
This shall be in addition to the two-character country codes as per ISO 3166 data being
encoded in a machine-readable symbol.
4.2.7 Production date – DI “16D”
Date code shall be in accordance with ISO 8601. When encoded in a machine-readable
symbol, either the data identifiers “10D”, “11D” or “16D” shall be used. Preference should be
given to “16D”.
The production date is determined by the manufacturer in an appropriate manner for the
specific product.
NOTE ISO 22742 recommends the format “16D” for the production date.
4.2.8 Package identification – DI “J” and “3S”
Unique package identification (i.e. licence plate) shall be in accordance with the
ISO/IEC 15459 series.
A licence plate with data identifier “J” is the recommended format.

– 10 – IEC 62090:2017 © IEC 2017
If there are several layers of packages with a 1:1 relation each, then the same package ID is
to be used for the labels on the different levels of packaging. If there is more than one
package in a package, then there shall be different package IDs.
EXAMPLE 1 A reel in a dry pack in a pizza box all have the same package ID on their respective labels.
EXAMPLE 2 Multiple reels in one pizza box each have different package IDs, and the pizza box itself has another
ID, too.
NOTE 1 However, as there is also the unique company code according to the ISO/IEC 15459 series with data
identifier “18V” as mandatory data element, global uniqueness can be achieved by the combination of this unique
company ID and a package ID unique within the domain of this company with data identifier “3S”.
NOTE 2 When using “3S”, this element is not suited to be used as primary key in an RFID tag in case of future
RFID marking of the component package.
4.3 Optional data elements
4.3.1 Expiration date – DI “14D”
An expiration date may be shown on a package label when the packaged items need to be
consumed/processed (e.g. soldered) before a certain date, when stored under conditions
defined by the manufacturer.
The data format of the expiration date is YYYYMMDD.
4.3.2 Revision level – DI “2P”
The revision level specifies the revision or version of an item, e.g. engineering change level,
edition, or revision.
4.3.3 EIAJ ID – DI “3N”
Data identifier “3N” is a coding structure in accordance with the format defined by the
Electronic Industries Association of Japan (EIAJ).
Refer to Electronic Commerce Alliance for Global Business Activity (ECALGA) Standards.
4.3.4 Manufacturer location – DI “25L”
The global unique location code according to the ISO/IEC 15459 series is structured as a
sequence of three concatenated data elements: the issuing agency code (IAC), followed by
the company identification number (CIN), followed by the physical internal location code that
is unique within the CIN holder's domain, shall be used to identify a manufacturer’s location.
EXAMPLE 1 Using IAC LE (EDIFICE):  25LLEIBMABCDE
EXAMPLE 2 Using IAC UN (Dun&Bradstreet): 25LUN123456789ABCDE
NOTE The extension to the DUNS # for different locations is not needed when each location has its own DUNS #.
4.3.5 Customer assigned supplier code – DI “V”
Some customers use their own assigned codes for suppliers, and require this information also
on component packages.
It is to be considered that a customer-assigned vendor/supplier code is specific for this one
customer. Labels with customer-specific content cause additional efforts and challenges, e.g.
in case of production on stock, distribution via resellers or customer returns. Some distribution
models may not work when customer data is required on labels. Returning packages with
customer specific data usually will imply re-labelling. Therefore, using a customer-assigned
vendor/supplier code is allowed but not recommended by this document.

4.3.6 Moisture sensitivity level – DI “13E”
The moisture sensitivity level is a class of time period in which a moisture-sensitive device
can be exposed to ambient room conditions, according to IPC/JEDEC J-STD-020 and
IEC 61760-4. This is important information, especially for components exposed to soldering
processes. At least the moisture sensitivity level should be indicated for such components.
4.3.7 URL – DI “33L” and “34L”
A link to further information accessible via the internet for this specific package can be added
in a dedicated data element using data identifier and corresponding data structure “33L”, or
using the data identifier and corresponding data structure “34L”. See Annex C “URL” for
details.
NOTE 1 These DIs are used upon agreement between the supplier and the customer.
NOTE 2 Whether additional data or information is provided, what kind of data and how data is provided, is at the
discretion of the party owning the data.

Either “J” or “3S” applies. If “3S” is used, global uniqueness is achieved by combining this element with the
company ID “18V”.
d
One of the manufacturer assigned serial number formats “S” or “25S” shall be used.

e
Either quantity in format “7Q” or “Q” applies. Refer to Annex D of ANSI MH10.8.2.

4.5 Data representation
4.5.1 General formatting
All data elements shall be represented on the label as human-readable text. Mandatory data
shall be encoded in a 2D machine-readable symbol. In addition, some of the data should be
encoded in linear bar codes. See Table 2.

Mandatory information of linear bar code in this table shall be encoded in linear bar code whenever there is
enough free space on the label for these linear bar codes.

a
EIAJ has prescribed special data semantic rules and requirements for a linear bar code for component
packages intended to meet EIAJ requirements.

If the optional elements are used, then they shall be at least human-readable. And if they are
also machine-readable, then they shall be presented in a 2D symbol and optionally be
presented in a linear bar code. See Table 3.

4.5.2 General formatting for machine-readable symbols
4.5.2.1 General
In this document, machine-readable symbols are linear bar code symbols or 2D symbols.
4.5.2.2 Maximum symbol length
The maximum symbol length of a linear bar code symbol should be no more than 8 cm.
NOTE Depending on the choice of the scanning device: Only imagers can read 2D symbols and some imagers
have issues with longer linear bar codes.
4.5.2.3 Syntax in linear bar code
If linear bar codes are used, it is strongly recommended not to concatenate them. Each bar
code starts with the appropriate data identifier.
If concatenation is done, it shall be in accordance with ANSI MH10.8.2 (as referenced in
ISO/IEC 15418).
4.5.2.4 Syntax in 2D symbols
The encoding shall be as described in ISO/IEC 15434. See also Annex B.
4.5.3 General formatting for human-readable information
4.5.3.1 General
Human-readable information can be human interpretation, human translation, data titles or
free text and data.
4.5.3.2 Human-readable interpretation
A human-readable interpretation (HRI) of each linear bar code symbol shall be provided
adjacent to the bar code. Such human-readable interpretation shall represent the encoded
data. See Figure 1.
The HRI shall represent the encoded data, exclusive of the data identifier. The data identifier
appears in parentheses as part of the data title, e.g. “(S) Serial #.”
The HRI of the linear bar code symbol shall be printed above the bar code symbol.
For 2D symbols, human translation (see 4.5.3.3) should be used.
4.5.3.3 Human translation
In addition to the HRI, human translation of machine-readable data may be provided in a
separate section of the label.

4.5.3.4 Data titles
Data titles for linear bar code symbols may be presented with a full data element title, e.g. “(S)
Serial Number 123456”, or an abbreviated data element title, e.g. “(S) Ser. No. 123456”. The
data element title is following the data identifier. It is recommended to put the data identifier in
round brackets and have one or few space characters between the data identifier and the rest
of the data area title.
If the real estate available for marking is insufficient to support the marking of the data
element title and the data identifier, the data title may be abbreviated to only include the data
identifier enclosed in parentheses, e.g. (S) 123456.
4.5.3.5 Free text and data
Human-readable information that is not a translation of machine-readable information may be
added. These data titles should not include data identifiers.
4.6 Data carrier selection
4.6.1 Linear bar code symbols
The linear bar code symbologies to be used in this document are as follows:
• Code 39 (reference: ISO/IEC 16388);
• Code 128 (reference: ISO/IEC 15417).
Code 128 requires less space than Code 39, and supports a wider character set. The choice
of any of the linear bar code symbologies above is up to the manufacturer.
Recommended symbol parameters of the bar code symbols are shown in Table 4 and Table 5
below.
For the Code 39 symbology, the optional check digit shall not be encoded.
This document recommends a minimum narrow element width of 0,25 mm, but in no case
shall the minimum narrow element be less than 0,17 mm. If narrow element widths of less
than 0,25 mm are used, trading partners shall acknowledge the need to use scanning
equipment suitable to read this small narrow element width. Regardless of the narrow element
width, the linear symbol shall meet the minimum print quality requirements (see Table 4 and
Table 5).

4.6.2 Two-dimensional (2D) symbols
4.6.2.1 General
The 2D symbologies for use in this document are as follows:
• Data Matrix ECC 200 (reference: ISO/IEC 16022; includes also some rectangular formats);
• QR Code (reference: ISO/IEC 18004).
PDF417 is still used on packages, and shall be supported too. However, processing all labels
according to this document does require imager readers. For imager readers, real matrix
codes such as Data Matrix or QR Code are much better suited than PDF417 and require
significantly less space. Therefore, this document does not recommend PDF417 for new
applications.
The choice of any of the 2D symbologies above is up to the manufacturer.
4.6.2.2 “X” dimension
The recommended minimum “X” dimensions for each of the cell sizes for Data Matrix ECC 200
and QR Code are 0,17 mm.
The X dimension shall be determined by the printing capability of the manufacturer/printer
of the label.
