Customs exemption limits ad valorem duty on unhardened gelatin imports, restricting charges above the prescribed statutory cap. The Central Government exempts worked unhardened gelatin and articles of unhardened gelatin under sub heading 9602.00 from that portion of customs duty specified in the First Schedule which exceeds 60% ad valorem when imported; the exemption is taken in the public interest and comes into force on 28 February 1986.
