US-Singapore FTA — qualifying goods may enter duty-free

Among US trading partners for plastics, Singapore plays a notable role, with approximately $70B in total bilateral trade.

The current tariff framework for plastics from Singapore reflects the post-SCOTUS landscape: a 10% Section 122 tariff replaced the previously higher IEEPA rates after the Court's February 2026 ruling.

The Section 122 tariff is subject to a 150-day statutory time limit and is set to expire approximately July 24, 2026, unless Congress acts to extend or replace it. Importers should monitor legislative developments closely as this deadline approaches.

Plastics (HTS Chapter 39) carry an average MFN duty rate of 4.2% in addition to the Section 122 tariff. No additional Section 232 or Section 301 surcharges apply to most products in this category from Singapore.

Singapore is party to the US-Singapore FTA, which may provide preferential or duty-free access for qualifying plastics. Importers should verify rules of origin requirements to take advantage of preferential rates.

Key products in HTS Chapter 39 imported from Singapore include Polyethylene, Polypropylene, PVC pipe, PET bottles, Plastic bags, and Plastic containers.
