Last updated: August 2026 dataKnitted or crocheted construction in synthetic fiber — predominantly polyester — characterizes this heading, which covers window curtains, drapes, interior blinds, and bed valances for residential and commercial interior furnishing applications. The US schedule splits the heading between window shades and blinds (6303120010) and other curtains, drapes, and valances (6303120090), with a legacy catch-all at 6303120000. Sheer polyester curtain panels and roller-blind fabrics in knit construction are the dominant commercial forms. Section 301 tariffs apply to goods of Chinese origin, and China has historically been a major supplier of synthetic knit curtain fabrics, making tariff engineering and origin verification important considerations for importers and retailers sourcing in this category.

CBP generally treats 'blinds' as coverings with adjustable slats or panels that control light by tilting or stacking, while 'shades' are single-panel coverings that roll, fold, or pull down. Both fall within 630312 when made of synthetic knit fabric, but the US schedule separates them at the 10-digit level (6303120010 for shades and blinds versus 6303120090 for curtains and drapes). The product's operating mechanism and trade description should be documented to support the correct line.
Classification is based on the essential character of the curtain fabric itself, not on minor woven trim or header tape components. If the main curtain body is knitted or crocheted synthetic fabric, the article is classified under 630312. However, if the woven component is substantial enough to alter the essential character, reclassification to a woven curtain heading may be appropriate. A binding ruling from CBP is advisable for products with significant mixed-construction elements.
