In the meeting, India will make a pitch for continuation of the three-tier system of tariff or tax elimination for member countries as a few countries favour only one tier, an official said.
The official added that some, including China, are pushing to increase the number of products that will attract zero duty.
"The meeting is crucial as members have to finalise the contours before the trade ministers meet in August. India may increase the number of products, but would not go for zero duty on those. It will propose to reduce taxes on those incremental goods," the official said.
Similarly, for Japan and South Korea, it has offered to open up 65 per cent of its product space.
