Classification of silk curtains under HS 6303.99
Silk curtains are classified within the Harmonized System under Chapter 63, which pertains to other made-up textile articles, sets, worn clothing, and worn textile articles. The classification process for curtains involves identifying the primary material and the method of construction. Heading 6303 is dedicated to curtains (including drapes) and interior blinds, as well as curtain or bed valances. To arrive at the specific subheading 6303.99, one must first distinguish between knitted or crocheted items and those that are woven or otherwise \"made up.\" Since most high-end silk curtains are woven, they fall under the second category of the heading. Furthermore, the subheadings are divided by material type: cotton (6303.91), synthetic fibers (6303.92), and other textile materials (6303.99). As silk is a natural protein fiber and is not categorized as cotton or a synthetic fiber, it is classified under the \"other\" category. This classification ensures that the unique luxury status and material properties of silk are accounted for in international trade statistics and tariff applications. The term \"made up\" is crucial here; it implies that the fabric has been cut to shape, hemmed, or otherwise finished into a final consumer product. If the silk were merely a roll of fabric, it would be classified in Chapter 50. However, once it is sewn into a curtain with grommets, hooks, or a rod pocket, it moves to Chapter 63. This distinction is vital for importers to ensure they are paying the correct duty rates, which can vary significantly between raw fabrics and finished home textiles. The classification also covers interior blinds made of silk, provided they are not of the type used for windows in vehicles.

Codes often confused with 6303.99
Common mistake. Silk curtains are often confused with HS code 6303.19, which is for knitted or crocheted curtains of other textile materials. If the silk curtain is woven, 6303.19 is incorrect. Additionally, importers sometimes mistakenly use 5007, which is the code for woven silk fabric in the piece. Once the fabric is hemmed or finished into a curtain, it must be moved to 6303.99. Finally, curtains made of synthetic silk (polyester) must be classified under 6303.92, not 6303.99.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
