What is HS 550931?
HS 550931 covers yarn made from acrylic staple fibers, not put up for retail sale, containing 85% or more acrylic or modacrylic fibers by weight. It sits within Chapter 55 of the Harmonized System, which covers man-made staple fiber yarns. Procurement teams should distinguish this code carefully from blended yarn codes in the 5509 heading, as even minor fiber composition changes can shift classification and duty treatment.
End-use applications span a wide range of industries: apparel and knitwear manufacturing represent the dominant demand segments, while home textiles such as blankets, upholstery fabrics, and carpeting account for significant secondary consumption. Industrial textile applications also exist, though they are a smaller share of total trade volume. For any importer, accurate classification at the HS 550931 level is essential to avoid customs delays and post-clearance audits.
Top Sourcing Countries for Acrylic Staple Fiber Yarn
Global supply of acrylic staple fiber yarn is moderately concentrated, with China, Turkey, India, South Korea, and Taiwan collectively accounting for the bulk of export capacity. Each origin carries distinct cost and compliance implications.
- Turkey is the leading supplier into the Indian import market by value share, reflecting its established spinning infrastructure and competitive labor costs. Turkish exporters have built strong relationships with South Asian buyers and offer reliable mid-range quality tiers suited to knitwear and apparel end uses.
- China maintains structural advantages in scale and vertical integration, with domestic acrylic fiber production feeding directly into yarn spinning. However, buyers sourcing from China into certain markets must account for anti-dumping scrutiny and transshipment risk assessments.
- India is simultaneously a producer and an import market, sourcing specialty yarn grades from Europe — notably France, the United Kingdom, the Netherlands, Italy, and Romania — suggesting active demand for higher-specification product tiers not fully met by domestic or Asian supply.
- South Korea and Taiwan offer technically advanced yarn production with consistent quality certifications, making them preferred origins for industrial textile and performance apparel applications where specification tolerance is tight.
European suppliers (FR, GB, NL, IT, RO) hold a combined meaningful share of imports into India, indicating that price alone does not drive all sourcing decisions — quality differentiation and product specification remain competitive levers.
Import Duty Rates and Trade Agreements
For imports into India, both China and Turkey face a Most Favoured Nation (MFN) tariff rate of 7.5% on HS 550931. This parity means origin selection for the Indian market is driven primarily by total landed cost, quality, and lead time rather than duty arbitrage between these two origins.
Procurement managers sourcing into other major markets should verify whether preferential trade agreements apply. The EU, for example, extends GSP benefits to qualifying developing country exporters, which can materially reduce effective duty rates compared to MFN. Buyers importing into the United States should monitor Section 301 tariff exposure on Chinese-origin textile inputs, which can substantially alter landed cost calculations. Always confirm current preferential rate eligibility with your customs broker before finalising supplier selection.
Cost Drivers and Price Outlook
Acrylic staple fiber yarn pricing is directly tied to upstream acrylic fiber costs, which in turn are derived from acrylonitrile — a petrochemical feedstock linked to crude oil pricing. With Brent crude up approximately 7.4% month-on-month as of early 2026, feedstock cost pressure is building across the acrylic fiber supply chain. Buyers should anticipate this flowing through to yarn contract renewals on a lagged basis, typically within one to two quarters.
Energy costs represent a significant secondary driver, particularly for spinning operations in energy-intensive markets. Aluminium is up 10% month-on-month and coking coal has risen 14.6%, signalling broader industrial energy and input cost inflation that indirectly pressures manufacturing overhead across textile producing regions. Currency fluctuations — particularly Turkish lira and Chinese renminbi movements against the US dollar — can create short-term landed cost opportunities or risks that procurement teams should monitor actively when negotiating forward contracts.
Compliance and Sourcing Considerations
HS 550931 carries a medium transshipment risk rating. In practice, this means customs authorities in key import markets may scrutinize certificates of origin more closely, particularly for Chinese-origin yarn routed through third countries. Importers should require full chain-of-custody documentation and verify mill-level origin declarations to avoid misclassification penalties or anti-dumping liability.
Country of origin is especially consequential for this product given the prevalence of textile-specific trade remedies in the US, EU, and other major markets. Conduct regular supplier audits and request binding origin rulings where volume and value justify the administrative cost. Anti-dumping measures targeting specific origins can change on relatively short notice, so staying current with trade remedy registers in your target import market is non-negotiable.
How to Source Acrylic Staple Fiber Yarn Efficiently
Effective procurement of HS 550931 starts with supplier diversification across at least two origin countries to reduce single-source concentration risk. Given medium supply concentration globally, over-reliance on one origin — particularly during periods of currency volatility or trade policy change — exposes buyers to avoidable disruption.
- Verify fiber composition certifications to confirm HS 550931 classification and avoid reclassification risk at border.
- Request mill test reports and quality consistency data, particularly when switching from European to Asian origins or vice versa.
- Model total landed cost including MFN or preferential duty, freight, insurance, and any applicable trade remedy duties — not just ex-works price.
- Monitor Brent crude and acrylonitrile spot price trends as leading indicators for yarn price negotiations.
- Engage a licensed customs broker familiar with textile classification in your import market before onboarding new suppliers.
