Written to help non-specialists understand this page. Rates, dates, and legal facts come from the official records above and on the linked source.
HTS heading 4704 covers chemical woodpulp made by the sulfite process, excluding dissolving grades. In plain language, it groups wood pulp produced using sulfite chemicals when the pulp is intended for ordinary paper, paperboard, or similar uses—not highly purified dissolving pulp used to make products such as certain fibers or chemical derivatives.
Heading 4704 is only a 4-digit category, not the complete tariff classification. To reach the correct 8-digit HTSUS code, follow the subheadings under this heading and identify the product’s specified type or material characteristics, as described in the current tariff schedule. The product’s composition, processing method, and presentation may all matter; do not choose a code based only on its commercial name.
What to check
- Confirm that the pulp was produced by the sulfite chemical process, rather than the kraft (sulfate) process or a mechanical process.
- Verify that the product is not a dissolving grade; review the technical specification, intended use, and supplier documentation.
- Read every subheading under heading 4704 and match the product to the stated pulp type, material, or other distinguishing description.
- Collect supporting documents such as the mill specification, certificate of analysis, product data sheet, and invoice description.
- Have a customs broker or classification specialist review the 8-digit selection when the production process, grade, or technical description is unclear.
HTS heading 4704 summary
Chemical woodpulp is a 4-digit product category containing 4 published product-code lines in this snapshot. A heading does not carry one universal duty rate; classification must be narrowed to the line matching the product facts.
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.
