HTS heading 8451 is a broad product category for textile-processing machinery, excluding machines classified in heading 8450. It covers equipment that washes, cleans, dries, irons, presses, bleaches, dyes, finishes, coats, or impregnates textile yarns, fabrics, and made-up textile articles. It also includes certain machines used to apply paste in making floor coverings, plus machines for reeling, unreeling, folding, cutting, or pinking textile fabrics. Parts designed for these machines can also fall within the heading.
To narrow the heading to a specific 8-digit HTS provision, first identify the machine’s principal function and the textile operation it performs. Then read the relevant subheadings and tariff provisions, which may distinguish among machine types, intended textile materials, processing methods, or whether the item is a complete machine or a part. The exact structure is product-specific; do not assume every machine is classified by material alone. In the US tariff, a statistical suffix may also be required beyond the 8-digit provision.
What to check
- Describe the machine’s actual operation, including whether it washes, dries, dyes, finishes, cuts, folds, or performs another listed function.
- Confirm that the equipment is for textile materials or textile articles and is not a household laundry machine covered by heading 8450.
- Check whether the item is a complete machine, a dedicated part, or a general-purpose component; parts classification can depend on design and principal use.
- Review the heading, subheading notes, legal notes, and the full tariff descriptions for competing provisions before choosing the 8-digit code.
- Use manufacturer specifications, diagrams, model information, and prior customs rulings when available; ask a customs broker or request an official classification ruling if the machine has multiple functions.
HTS heading 8451 summary
Machinery is a 4-digit product category containing 5 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.

Common questions
What products fall under HTS heading 8451?
Machinery (other than machines of heading 8450) for washing, cleaning, wringing, drying, ironing, pressing (including fusing presses), bleaching, dyeing, dressing, finishing, coating or impregnating textile yarns, fabrics or made up textile articles and machines for applying the paste to the base fabric or other support used in the manufacture of floor coverings such as linoleum; machines for reeling, unreeling, folding, cutting or pinking textile fabrics; parts thereof. To classify a specific item you must pick the matching sub-category and 8-digit code above; the right choice usually depends on the material and construction of the product.
How do I choose the right code within this category?
Start from the sub-categories (typically divided by material—for example cotton versus man-made fibers), then open the active 8- or 10-digit code that matches the product. When unsure, a licensed customs broker or a CBP binding ruling can confirm the classification.
