U.S. imports of engineered structural timber products (other) (HS 441889) totaled $6.5M in April 2026, traded with 12 countries.
Importers of Engineered Structural Timber Products (Other) paid $38K in duties in April 2026 — an effective duty rate of 30% on $126K in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataCross-laminated timber (CLT), laminated veneer lumber (LVL), parallel strand lumber (PSL), and other factory-engineered wood structural products not elsewhere specified fall under this heading, which covers the broad residual category of precision-manufactured wood members used in mass-timber and conventional construction. Canada and China are the leading US suppliers, with Mexico, Austria, and Italy also contributing — a supplier mix that reflects both proximity-driven North American trade and Europe's advanced mass-timber manufacturing sector. Products from China may be subject to Section 301 tariffs, making origin documentation critical at entry. All goods are classified under the single tariff line 4418890000.

Engineered structural timber products classified under 4418890000 and originating from China may be subject to Section 301 tariffs. Importers should confirm the current list applicability and any applicable exclusions with CBP or a trade attorney, as Section 301 coverage and exclusion status can change.
Cross-laminated timber consists of layers of solid-sawn lumber glued at alternating right angles, giving it two-way structural performance. LVL and PSL, by contrast, align grain in a single direction for beam and column applications. Both types fall under 4418890000 when they are not I-beams (441883) or glued laminated timber classified elsewhere, but the structural specification and fire-rating documentation required by US building codes differ significantly between them.
