Tariff Protection for Fiberglass Industry

Tariff changes apply to specific articles listed under Section 104 of Presidential Decree No. 1464, as amended.
Import duties are structured with varying rates from 1983 to 1987 for these items:
- Heading 68.07: Covers slag wool, rock wool, mineral exfoliated materials, vermiculite, expanded clays, foamed slag, and other heat or sound-insulating mineral materials except those under Headings 68.12, 68.13, or Chapter 69.
  - General rate: 20% ad valorem.
  - Panels and boards made of mineral wool: 40% (1983-1985), 30% (1986), 20% (1987).
  - Other categories maintain a 20% duty rate.
- Heading 70.20: Includes glass fiber (including wool), yarns, fabrics, and derived articles.
  - Glass fiber: 30% ad valorem consistently.
  - Glass wool and products: 40% (1983-1985), 30% (1986 and 1987).
  - Other items: 40% ad valorem consistently.

Any unjustified increase in prices of locally produced fiberglass insulating materials benefiting from these tariff protections is a ground for tariff modification.
The Board of Investments (BOI) is tasked with monitoring local product prices.
The BOI shall represent to the Tariff Commission for appropriate tariff adjustments according to Section 401 of the Tariff and Customs Code if price manipulation or concerns arise.

All prior orders, rules, and regulations, or their parts, inconsistent with the provisions of this Executive Order are repealed.

The order takes effect as stated with tariff changes beginning on January 1, 1983.
The issuance and enforcement of this order are under the authority of the President of the Philippines and pursuant to the powers granted under Presidential Decree No. 1789 (Omnibus Investment Code).
