About HS Code 391729
This "basket" HS code covers rigid tubes, pipes, and hoses made from plastics *other than* ethylene, propylene, or vinyl chloride polymers. This category includes a wide range of specialized engineering plastics and high-performance polymers, each offering unique properties like extreme temperature resistance, chemical inertness, or high mechanical strength. Importers are diverse, serving niche markets such as aerospace, medical devices, chemical processing, and high-tech manufacturing, where standard plastic pipes are insufficient. Exporters are typically specialized manufacturers working with advanced polymer compounds. The trade in these products is often high-value, driven by specific industrial requirements and stringent performance standards. Key considerations include the precise polymer type (e.g., PTFE, PVDF, PEEK, ABS), chemical compatibility, temperature range, and specific certifications required for critical applications.
Products Under This Code
PTFE rigid tubing, PVDF chemical pipes, ABS drainage pipes, PEEK high-temperature pipes, Nylon rigid conduits, Polycarbonate rigid tubes, CPVC hot water pipes, PPSU medical tubing
Real World Examples
