HTS heading 4418 is a broad product category for builders’ joinery and carpentry made of wood. It generally groups construction-related wood products such as cellular wood panels, assembled flooring panels, and wooden shingles or shakes. The heading describes the product’s function and form, not one single finished item or duty treatment.
To reach the correct 8-digit HTSUS code, start with the product’s exact identity and intended use, then follow the more detailed subheadings and statistical provisions under heading 4418. The available code often depends on the type of product, its construction, and the wood or material involved. Confirm the complete product description, manufacturing process, and any applicable notes before using the code for entry.
What to check
- Identify whether the item is a panel, assembled flooring, shingle, shake, or another type of builders’ joinery or carpentry.
- Check the product’s construction, including whether it is cellular, assembled, laminated, finished, or combined with other materials.
- Determine the relevant wood species or material composition when the subheading distinguishes products that way.
- Review the full HTSUS heading, subheadings, legal notes, and statistical descriptions rather than stopping at the 4-digit heading.
- Compare the classification with official Customs guidance or ask a customs broker when the product has multiple materials, unusual construction, or more than one possible heading.

How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.
