COMMISSION OF THE EUROPEAN COMMUNITIES 
COM(89) 442 final 
Brus se Is, 21 September 1989 
Proposal for a 
COUNCIL REGULATION (EEC) 
temporarily suspending the autonomous Common Customs Tariff duty 
on certain industrial products 
(microelectronics and related sectors) 
(presented by the Commission) 
EXCLAMATORY MEMORANDUM 
1. In the first quarter of this year the Ocnmissicn, with the 
assistance of the Economic Tariff Problems Group, examined all the 
requests sent in by the Member States for temporary suspension of 
Oonmon Customs Tariff duties, including the requests for the renewal 
of suspensions at present in force. 
2. The proposal for Regulations for temporary suspension of autonomous 
Oonmon Customs Tariff duties on agricultural products 
has already been sent to the Council. The attached, proposal concerns 
industrial products of the microelectronic and allied sectors. For the other 
industrial products a proposal is under preparation. 
3. As in the case of the other product categories, the principle 
followed when examining the requests for suspension relating to the 
products mentioned above was to grant total suspension where 
Oonraunity production of the product in question is minimal or 
non-existent, and partial suspension where Oonmunity production only 
partially caters for Ocmnunity requirements. For the latter, the * 
rate of suspension varies according to the supply possibilities open 
to users within the Community.' Similarly, in certain cases involving 
particularly sensitive sectors, suspension was refused so as to 
protect a Ocmnunity industry which was starting up. 
In this way, the Gcntnission seeks to teep a balance between the 
interests of producers, users and consumers. 
Moreover, the need to safeguard jobs within'the Community has been 
constantly borne in mind. 
4. Given the criteria listed above, at the present stage the Oanmission 
feels that suspension of duty is justified for those products listed 
in the Annex to the attached draft Regulation. 
However for a number of suspension requests, consultations axe 
still under way with the Community firms which might be 
producing identical or equivalent products. If, in the 
light of these consultations, it transpires that the 
granting of suspension in no way harms a Ocnmunity 
product, the Commission will male a proposal, in the 
discussions in the Council, to add the products covered 
by such requests to the list annexed to the attached 
draft Regulation; 
In order to simplify the procedure, these goods have already been 
inserted into the list, but put between square brackets. 
- 2 -
As stated in Article 1 of the draft Regulation, the proposed period 
of validity is 6 months. 
Particular attention is drawn to the fact that, in order to apply it 
properly this Regulation must be published at least two months before 
entering into force. 
COUNCIL REGULATION (EEC) No 
of 1989 /89-
temporarily suspending the autonomous Common Customs Tariff duty on certain industrial 
products 
(microelectronics and related sectors) 
THE COUNCIL OF THE EUROPEAN COMMUNITIES, 
Having regard to the Treaty establishing the European 
Economic Community, and in particular Article 28 
thereof. 
Having regard to the proposal from the Commission, 
Whereas production of the products referred to in this 
Regulation is at present inadequate or non-existent within 
the Community and producers are thus unable to meet the 
needs of user industries in the Community; 
Whereas it is in the Community's interest in certain cast* ro 
suspend the autonomous Common Customs Tariff du»ii.» 
only partially, particularly because of the existence of 
Commuiiity production, and in other cases to suspend them 
completely; 
Whereas, taking account of the difficulties involved in 
accurately assessing the development of the economic situation in the sectors concerned in the near future, these 
suspension measures should be taken only temporarily, by 
fixing their period of validity by reference to the interests of 
Community production. 
HAS ADOPTED THIS REGULATION: 
Article 1 
The autonomous Common Customs Tariff duties for the 
products listed in the table appearing in the Annex shall be 
suspended at the level indicated in respect of each of 
them. 
These suspensions shall apply from A 3*«u*ry to 3© J*me, 
Article 2 
This Regulation shall enter into force on 1 X+***kr*f A JftO. 
This Regulation shall be binding in its entirety and directly applicable in all Member 
States. 
Done at Brussels, 1989.
