Plain-language explainer

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 6603 is a parts-and-accessories category for umbrellas, sun umbrellas, walking-sticks, seat-sticks, whips, riding-crops, and similar articles covered by heading 6601 or 6602. It generally includes items such as frames, shafts, handles, ribs, covers, and other components or trimmings, but the exact scope depends on the product’s design and intended use.

The four-digit heading is only the starting point. To reach the correct 8-digit HTSUS subheading, read the successive legal descriptions and choose the branch that matches the item’s material, construction, or type. Confirm whether the item is a complete part, a fitting or accessory, or another specifically described component; then verify the current HTSUS text, unit of quantity, and any relevant notes or exclusions. Borderline classifications may require a customs broker or a binding ruling from U.S. Customs and Border Protection.

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.

👉 The exact numbers live on each product code page.

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.
