HEPA-Grade Glass Fiber Filter Media Rolls
Continuous rolls of microglass paper made from fine glass fibers for manufacturing high-efficiency particulate air (HEPA) filters. Classified as glass fiber filters under HTS 7019.90.51.40 when in filter media form meeting glass wool criteria.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in chopped strand mat form rather than non-woven filter paper
Chopped glass fiber mats classify earlier in heading 7019 sequence.
If marketed as felted paper despite glass content
Composite paper/felt materials shift to Chapter 48 if paper dominates.
If pre-pleated and framed as complete HEPA modules
Finished air filter cartridges are filtering equipment parts.

Import Tips & Compliance
• Measure and declare roll dimensions precisely; weight-per-unit-area affects duty calculation
• Provide MERV rating documentation linking to glass fiber efficiency properties
• Avoid cutting to shape pre-import to prevent 'worked glass' reclassification
