* Apart from these HS codes, Battery separators of fibre glass are also
imported in nominal amounts under the HS codes - 70109000, 70199090
(included in Imports value above)
** Under these HS codes as well as under 39201019 & 39042110,
Battery separators made of PVC/PE without glass-fibre mats valuing
over Rs 100 crore are also imported
China accounts for over 70-80% of imports of fibre-glass battery separators of India with HS code
70X followed by Thailand with 20-25% share. Singapore, Germany & Japan account for less than 5%
of fibre-glass battery separators imports of India.
Under the HS code 85X, China accounts for 40-50% of imports of battery separators of India
followed by Thailand, Hong Kong, Taiwan, Indonesia & France accounting for around 40-50%
imports. The remaining imports of glass-fibre based battery separators are from UK, Germany, US,
Japan and Philippines.
The glass-fibre based battery separators are not exported from India.
Raw materials
The absorbent glass mats (AGM) are manufactured by dry-laid process, wet-laid process, spun-bond
process or melt-blown process using glass fibre / glass wool.
All these processes consist of three steps:
a. making fabric webs,
b. bonding webs and
c. post-treatment
and in most cases the web making and bonding are done in one step.
Quality Control and standards
There are no standards pertaining to battery separators. The manufacturers have their own set of
specifications based on the battery performance requirements.
Cigarette Filter
Cigarette filter reduces harshness of tobacco smoke by reducing the amount tar, smoke and other fine
particles during combustion of the tobacco portion. The filter is primarily made-up of cellulose acetate
fibres known as tow. The fibres are bonded together with a hardening agent, tri-acetin plasticizer,
which helps the filter to keep its shape. The filter is wrapped in paper and sealed with a line of
adhesive.
