Import Tips & Compliance

Verify treatment certification (e.g

AWPA standards) and include phytosanitary certificates to meet ISPM 15 fumigation requirements

Declare exact dimensions and treatment type on entry docs; rough-squared posts over 4x4x8ft may trigger quota checks

Avoid common pitfall of classifying as finished posts (4406); measure moisture content to confirm 'in the rough' status
