Last updated: August 2026 dataCommercial and non-commercial greenhouses of metal (9406900110 and 9406900120), other prefabricated metal buildings (9406900125 and 9406900130), plastic animal sheds (9406900150), and a residual NESOI line (9406900190) make this heading unusually diverse in both material and end-use. Canada leads supply, with Israel a notable source specifically tied to greenhouse technology exports — Israel is a recognized global innovator in controlled-environment agriculture structures. Metal prefabricated buildings of Chinese origin may be subject to Section 301 tariffs, and steel-content structures could also trigger Section 232 considerations depending on how the article is classified at the component level.

The distinction between 9406900110 (commercial) and 9406900120 (non-commercial) greenhouse lines turns on the intended use of the structure. Commercial greenhouses are those used in agricultural production for sale, while non-commercial structures serve residential or hobbyist purposes. Importers should retain purchase orders, end-user declarations, or business documentation that establishes the commercial or non-commercial nature of the buyer's operation.
Plastic animal sheds (9406900150) are industrial/structural goods and do not themselves trigger mandatory agency admissibility review. However, if the sheds are imported pre-fitted with feed or water systems, or if they are destined for use with regulated livestock operations, importers should confirm whether any USDA APHIS or state agricultural regulations apply to the facility use — those requirements are separate from the customs classification.
