HTS heading 4009 is a broad product category for tubes, pipes, and hoses made of vulcanized rubber other than hard rubber. It can include the rubber item by itself or with fittings such as joints, elbows, or flanges. The heading generally covers hollow rubber products used to carry or direct liquids, gases, or other materials, rather than every rubber article with a hole in it.
To reach the correct 8-digit HTS code, start with the product’s physical characteristics and intended use, then follow the subheadings and statistical subdivisions under heading 4009. The detailed code commonly distinguishes products by factors such as whether they are reinforced or otherwise combined with textile, metal, or other materials; whether they are designed for particular applications; and whether fittings are attached. Confirm the exact wording and any relevant legal notes in the current HTSUS before classifying the shipment.
What to check
- Identify whether the item is a tube, pipe, or hose, and document its construction, dimensions, and intended function.
- Confirm that the rubber is vulcanized and not hard rubber; obtain material specifications from the manufacturer when needed.
- Check whether the product is reinforced or combined with textile, metal, plastic, or another material, and determine how that construction is described in the subheadings.
- Record whether fittings are supplied or attached, and review the applicable subdivision language rather than assuming fittings change the heading automatically.
- Compare the product facts with the current HTSUS text, legal notes, and relevant Customs rulings; ask a customs broker or classification specialist when the construction or principal use is unclear.

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.
