The internal fabric pockets do not constitute 'covering' per HTS notes distinguishing cores from upholstered goods.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported with separate stuffing materials
When bundled with non-spring fillings, it may classify as assembled bedding parts rather than pure innerspring.
If pocket fabric imported separately from coils
Textile fabric for spring encasement falls under man-made textile articles if not combined.
If for seats or other furniture applications
End-use shift to non-bedding furniture changes classification from Chapter 94 bedding to seats.

The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Document pocket fabric as integral to coil function, not upholstery, to prevent reclassification
• Check for anti-dumping duties on steel coils; source certifications help avoid delays
