HS code for Modacrylic blend fabric: 5515.29
Fabrics, woven, of acrylic or modacrylic staple fibres n.e.c. in chapter 55, mixed mainly or solely with fibres n.e.c. in item no. 5515.2.
Classification of modacrylic blend fabric under HS 5515.29
Modacrylic blend fabrics are classified under HS code 5515.29, a designation within Chapter 55 which covers man-made staple fibers. Heading 5515 is reserved for "Other woven fabrics of synthetic staple fibers." The classification process for these textiles is heavily reliant on Section XI of the Harmonized System, specifically Note 2, which dictates that fabrics consisting of two or more textile materials are classified as if they consisted wholly of that one textile material which predominates by weight over any other single textile material. In the case of 5515.29, the fabric must contain a predominant weight of acrylic or modacrylic staple fibers. The sub-heading 5515.29 is a residual category for blends that do not fall into the more specific categories of 5515.21 (mixed with wool) or 5515.22 (mixed with man-made filaments). Modacrylic is a technical fiber known for its inherent flame resistance and chemical stability, often used in industrial protective clothing. To ensure correct classification, importers must provide a detailed fiber breakdown. If the fabric were made of continuous filaments rather than staple fibers, it would be classified in Chapter 54. The staple nature refers to fibers that have been cut to specific lengths before being spun into yarn and subsequently woven into fabric.

Codes often confused with 5515.29
Common mistake. This code is often confused with 5515.21, which is specific to blends with wool or fine animal hair, and 5515.22, which covers blends with man-made filaments. Additionally, if the modacrylic is blended with more than 85% of another fiber, such as cotton, it may be classified under Chapter 52 (e.g., 5211) rather than Chapter 55.

Cambodia did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 81% of its imports here ($20M, CEPII BACI), so it may also belong among the top importers.

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).
