Last updated: July 2026 dataWood shingles and shakes are split or sawn roofing and cladding elements used primarily in residential construction, with Western Red Cedar the dominant species due to its natural weather resistance and dimensional stability. The US tariff lines under this heading separate Western Red Cedar shingles (4418500010), other wood shingles (4418500030), and shakes (4418500050), reflecting the commercial importance of species identity in this market. Canada is by far the leading supplier, a position rooted in its vast Pacific Northwest cedar forests and established milling infrastructure, with Guyana and Colombia supplying tropical hardwood alternatives. Importers should verify whether any applicable softwood lumber trade-remedy measures extend to shingles and shakes, as scope determinations in that area have been contested.

Shingles are typically sawn on both faces to a tapered profile, producing a smooth, uniform surface, while shakes are split (or split and sawn) to create a rougher, more textured face. This manufacturing distinction is reflected in separate US tariff lines (4418500030 for shingles and 4418500050 for shakes), and importers should confirm the production method with the manufacturer to ensure correct classification.
The scope of US antidumping and countervailing duty orders on Canadian softwood lumber has been subject to ongoing litigation and scope rulings, and whether shingles and shakes fall within the order's scope has been a contested question. Importers of Canadian cedar shingles or shakes should consult a licensed customs broker or trade counsel to confirm the current scope determination before entry, as duty liability can be significant if the product is found to be within scope.
