STATUS OF HS TRANSPOSITIONS  
REPORT BY THE SECRETARIAT1 
Revision  
This report by the Secretariat seeks to  provide  an overview of the overall state of play of the different 
exercises  to transpose the WTO Schedules of concessions to take account of amendments of the 
Harmonized System (hereafter referred to as "HS Transpositions") . It complement s the existing  
reports on different aspects of the changes to the Schedules of concessions .2 
 
1. BACKGROUND  
Each WTO Member has a Schedule of concessions3, sometimes referred to as a "Goods Schedule", 
which is either annexed to the Marrakesh Protocol to the GATT 1994 or to a Protocol of Accession . 
Following the entry into force of the Harmonized System (HS) on 1  January  1988 (HS88), the 
pre-WTO Schedule s of those GATT Contracting Parties that were also contracting parties to the 
HS Convention were required to be transposed into the HS nomenclature .4 The GATT Committee on 
Tariff Concess ions developed procedures to this end.5  
 
Since the n, the World Customs Organization (WCO) has adopted partial  amend ments to  the 
Harmonized System Convention which  came into force on 1  January  1992 (HS92) , 1 January  1996 
(HS96), 1 January  2002 (HS2002), 1  January  2007 (HS2007), 1  January  2012 (HS2012) , 
1 January  2017 (HS2017) , and on 1 January  2022 (HS2022).   
 
With a view to keeping the authentic texts of the Schedules of concessions  up to date and in 
conformity with the national customs tariff,  GATT contracting parties and WTO Members have 
adopted a series of Decisions to transpose the Schedules of concessions in order to reflect the 
amendments to the HS.  These transposition procedures require Members to update the 
nomenclature us ed to express their concessions, including the bound duties , in their Schedules of 
concessions, thereby allowing a  compar ison with their MFN applied duties.   
 
2. PROCEDURES AND REPORTS BY THE SECRETARIAT  
Since the WTO Agreement entered into force, Members followed one pre -WTO procedure to 
transpose their Schedules of concessions into HS96 and have adopted eight Decisions relating to 
HS Transpositions.  The following is a list of the different procedures and reports by the Secretariat 
describing the s tatus of the different transposition procedures : 
 
 
1 This document has been prepared under the Secretariat's own responsibility and is without prejudice 
to the positions of Members or to their rights and obligations under the WTO.  
2 For example, the "Situation of Schedules of WTO Membe rs" that periodically circulate under the 
G/MA/W/23/Rev document series and the "Factual Report on the Status of Renegotiations under Article  XXVIII 
of the GATT 1994" that periodically circulate under the G/MA/123/Rev document series.  
3 See Article XI of the WTO Agreement.  
4 Article 3 of the HS Convention obliges HS contracting parties to ensure that their customs tariff and 
statistical nomenclatures are in conformity with the Harmonized System. It is to be noted that  those 
GATT  Contracting Parties that were not contracting part ies to the HS, but nevertheless applied the HS in their 
national customs tariff, also undertook this exercise in order to keep the authentic texts of their Schedule s up to 
date and in conformity with their national customs tariff.

  3. STAGES OF THE ONGOING TRANSPOSITIONS PROCEDURES  
While  the different HS Transposition s since 2005  are contained in a wide range of  Decisions as listed 
above, they are all based on similar steps  that can be summarized as follows:  
 
Step Description  
Step 1:  
Preparation of the 
draft HS 
transposition file  Since  2005, the Committee on Market Access decided6 that the 
Secretariat would undertake the HS2002 transposition of the Schedule s 
of developing country Members, except for those who decide d to prepare 
their own transposition.  Developed country Members were re quired to 
undertake their own transposition.  The same approach was taken in the 
HS 2007  and HS 2012  transpositions.  For HS 2017  and HS 2022 , there 
is no more distinction between developed and developing countries . 
Thus, the Secretariat shall transpose the Schedule s of all Members, 
except for those who decide to prepare their own transposition. Members 
that decide to undertake their own transposition shall submit all the 
required information to the Secretariat  in electronic form .7  
Step 2:  
Review by the 
Secretariat  For Members that prepare d their own transposition  file, the Secretariat 
is required to review it.  
Step 3:  
The Secretariat  
consult s with the 
Member concerned  If the Secretariat prepared the transposition file, it is sent to the Member  
concerned  for review and approval.  
If the Member prepared its own transposition file, the Secretariat 
provides  comments to the Member, if any.   
Step 4:  
Release for review 
by other Members  
 Once the technical issues have been cleared between the Member 
concerned and the  Secretariat,  or in the absence of a response from the 
Members for whom the Secretariat prepared the file, the transposition 
file is released for multilateral review by the oth er Members. These files 
are posted on the Tariff Analysis Online (TAO) Facility8 and an official 
notice is given to Members in a document of the corresponding 
G/SECRET/HSXX document series.  The files must be available for review 
for at least six weeks  before they can be considered in the HS multilateral 
review.  
Step 5:  
HS multilateral 
review  The transposition files are reviewed at an informal meeting of the 
Committee on Market Access referred to as " HS Multilateral Reviews ". 
The transposition files are considered approved once there are no 
comments pending on the file. Sometimes, the files are approved on an 
ad referendum  basis, with additional time for comments.  In case there 
are comments, the concerned Members meet bilate rally and inform the  
Committee of their progress. In case changes to the transposition file 
are required, a revised transposition file is prepared by the Secretariat 
and it  is released again for review by the other Members  (Step 4) .  
Step 6: Circulation 
pursuant to the  
1980 Procedures  Once a transposition file has been approved at an HS multilateral review  
and there are no comments pending , the file is circulated by the 
Secretariat under the 1980 Procedures for Modification and Rectification 
of Schedules9 in the G/MA/TAR/RS document series.  Under the 1980 
Procedures, Members are given a three -month period for review and 
objections.  
Step 7:   
Certification  Once the three -month  period has lapsed, and in the absence of 
objections, the Director General certifies the change s of the 
transposition , which are circulated in the WT/Let/ document series.

required).  31 19 12 4 210 
Note:   The total number of Schedules of concessions varies  over the years due to accessions to the WTO and 
enlargements of the European Union , so the numbers across the columns are not necessarily 
comparable . The table does not take account of Schedules of concessions that have been withdrawn.  
The Annex provides a detailed overview of the status of the HS transpositions for each Member. 
There is no column for HS2022 as the transposition exercise has not yet started.
 
10 On 17 October 2017, the European Union circulated a draft EU -28 Schedule, which takes into account 
the HS2007, HS2012, and HS2017 transpositions. See documents G/MA/TAR/RS/506 and its addenda . 
Reservations were introduced. The Unite d Kingdom withdrew from the European  Union as of 1 February 2020. 
The United Kingdom submitted a full Schedule in HS2017 ; see documents G/MA/TAR/RS/570 and its addenda .
