HS Code for Polypropylene tow

Polypropylene tow is classified under HS code 550140 because it meets the specific technical criteria for synthetic filament tow defined in the Harmonized System. According to the Chapter 55 notes, synthetic filament tow must consist of parallel filaments of a uniform length exceeding 2 meters. Furthermore, the tow must have a twist of less than five turns per meter and the filaments must be of a decitex of less than 67. HS code 550140 is specifically reserved for tow composed of polypropylene, a thermoplastic polymer. This classification is essential for distinguishing bulk filament assemblies intended for further processing, such as being cut into staple fibers, from finished yarns or monofilaments. The classification process involves verifying the chemical composition through laboratory analysis and confirming the physical dimensions and filament arrangement to ensure it does not fall under Chapter 54.

Products Included

• Polypropylene filament tow for staple fiber production
• High-tenacity polypropylene tow
• Parallel polypropylene filament bundles exceeding 2 meters
• Polypropylene tow for cigarette filter manufacture
• Unprocessed polypropylene filament assemblies for textile spinning

Common Misclassification

Polypropylene tow is frequently confused with HS code 5402, which covers synthetic filament yarn. The primary distinction is that 5402 includes yarn intended for immediate textile use, whereas 550140 is a precursor material. Another common error is classifying it under 550340, which is for polypropylene staple fibers. The difference lies in the length; 550340 applies to fibers that have already been cut to specific lengths (staple), while 550140 applies to continuous tow. Additionally, if the filaments exceed 67 decitex, the product may be classified as synthetic monofilament under 5404.

FAQ

What is the HS code for Polypropylene tow?

The HS code for Polypropylene tow is 550140, which specifically covers synthetic filament tow of polypropylene.

Does this code include cut staple fibers?

No, cut polypropylene staple fibers are classified under HS code 550340. HS code 550140 is strictly for continuous filament tow exceeding 2 meters in length.
