HTS heading 4810 is a four-digit category for paper and paperboard coated on one or both sides with kaolin (China clay) or another inorganic substance, with or without a binder. The coating must be the qualifying type, with no other coating; the paper may still be surface-colored, decorated, or printed. The goods can be in rolls or in rectangular or square sheets of any size.
Heading 4810 groups products at a broad level; it is not usually the complete classification for an entry. To reach the correct 8-digit HTSUS code, follow the applicable subheadings and compare details such as the paper or paperboard type, coating composition, weight or construction, physical form, and other product characteristics stated in the tariff description. The product’s commercial name alone is not enough, and a customs broker or ruling may be needed for difficult classifications.
What to check
- Confirm that the coating is kaolin or another qualifying inorganic substance and that there is no additional coating that changes the classification.
- Obtain the supplier’s technical specifications for coating materials, basis weight, composition, construction, and whether the product is paper or paperboard.
- Identify whether the goods are supplied in rolls or rectangular sheets, and check the relevant subheading wording for size, weight, or other required distinctions.
- Compare the complete product description with every lower-level subheading under 4810 rather than stopping at the four-digit heading.
- Keep product samples, specifications, invoices, and laboratory or supplier statements that support the selected 8-digit code; seek broker or official-ruling advice if the facts are uncertain.

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.
