U.S. Customs Rules Against Lumber Importer in Trade Evasion Case

Event summary

  • U.S. Customs and Border Protection ruled on May 4, 2026 that Coastal Forest Products evaded antidumping and countervailing duties on Canadian softwood lumber imports.
  • CBP rejected Coastal Forest Products' claim that lumber underwent 'substantial transformation' in New Zealand.
  • Coastal Forest Products will pay unpaid duties and post cash deposits on future entries of covered merchandise.
  • The U.S. Lumber Coalition filed the allegation that triggered the investigation.

The big picture

This ruling reinforces the Trump administration's aggressive trade enforcement stance, particularly against Canadian softwood lumber imports. The case highlights ongoing tensions in the lumber industry, where U.S. producers seek to protect domestic manufacturing from what they claim are unfairly subsidized Canadian imports. The strategic implication is a potential shift in import patterns as traders seek alternative routes to avoid duties, while domestic producers may accelerate expansion plans.
