What this does: This order removes a special import duty exemption for equipment used to manufacture perlite (a type of volcanic glass used in construction and horticulture).
Who it affects: Businesses importing "perlite manufacturing plant" — specifically equipment including hoppers, crushers, dryers, screeners, cyclones, scrubbers, furnaces, tanks, bins, and loaders (classified under tariff code 8419.39.90).
What changed: Previously, under Tariff Concession Order 0516045 (from 2005), this equipment could be imported without paying customs duty. As of 27 July 2011, that exemption is cancelled. Importers must now pay standard tariffs on this equipment.
Why it matters: This increases costs for companies importing perlite manufacturing machinery, likely to protect local manufacturers of similar equipment or because local industry no longer needed the protection that the concession originally provided.
