HTS heading 4504 is a broad product category for agglomerated cork and goods made from it. “Agglomerated” means cork granules, particles, or waste have been compressed and formed into a material, either with a binding substance such as an adhesive or without one. The heading can cover the agglomerated cork material itself as well as finished articles made from that material.
The 4-digit heading is only the starting point. To select the specific 8-digit HTSUS code, follow the subheadings under heading 4504 and match the product’s defining characteristics—such as whether it is raw agglomerated cork, a sheet, block, plate, strip, or another article, and whether additional specifications apply. Classification may also depend on the product’s construction and intended use, so unusual or composite goods may require customs-broker or classification-specialist review.
What to check
- Confirm that the product is made from agglomerated cork rather than natural cork, cork waste, or a different cork-based material.
- Review the product’s physical form carefully: identify whether it is supplied as a block, sheet, plate, strip, tube, or finished article.
- Check the lower-level HTSUS subheadings for distinctions based on material, composition, dimensions, processing, or product type.
- Keep product specifications, technical drawings, composition information, and photographs available to support the classification.
- For composite, highly processed, or unusual products, obtain a customs-broker review or seek an official classification ruling before importing.

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.
