HTS heading 4703 is a 4-digit product category for chemical wood pulp made by the soda or sulfate process, excluding dissolving grades. In plain language, it generally covers wood pulp produced with chemical cooking methods for uses such as papermaking, rather than pulp specially made to dissolve into chemical solutions for products such as certain fibers or cellulose-based materials.
The heading is only the starting point. To reach the correct 8-digit HTSUS code, follow the tariff structure through the relevant subheadings, which commonly distinguish the pulp by material or physical type, such as the kind of wood or whether it is bleached or unbleached. Confirm the product’s manufacturing process, grade, composition, and presentation against the current HTSUS wording and any applicable legal notes; a customs broker or classification specialist may be needed for borderline cases.
What to check
- Confirm that the pulp was made by the soda or sulfate process and is not a dissolving grade.
- Identify the wood source and check whether the tariff text distinguishes that material or type.
- Verify whether the pulp is bleached, unbleached, or otherwise described by a condition listed in the subheadings.
- Compare the product’s technical specifications, mill documents, and sample description with the full 8-digit HTSUS wording.
- Check the current HTSUS, chapter notes, and relevant Customs rulings before filing; ask a customs broker to review uncertain classifications.

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.
