5509.32 Yarn; (not sewing thread), multiple (folded) or cabled, of synthetic staple fibres, containing 85% or more by weight of acrylic or modacrylic, not put up for retail sale

A full HS code. These six digits are what goes on a customs declaration, and they mean the same thing in every country that uses the Harmonized System.

Section XI, Textiles & Apparel — silk, wool, cotton, man-made fibres, fabrics, carpets and clothing.

  1. 55 Chapter Man-made staple fibres
  2. 09 Heading Yarn (other than sewing thread) of synthetic staple fibres, not put up for retail sale
  3. 32 Subheading Yarn; (not sewing thread), multiple (folded) or cabled, of synthetic staple fibres, containing 85% or more by weight of acrylic or modacrylic, not put up for retail sale

Chapter 55 covers man-made staple fibres: synthetic and artificial fibres cut to short lengths for spinning into yarn, as opposed to the continuous filaments in chapter 54. Together chapters 54-55 cover the full range of synthetic textile inputs. Classification tip: As with chapter 54, synthetic versus artificial staple fibre is the first classification fork, and blended-fibre yarns are classified by the fibre with the greatest weight share.

The wording above is the Harmonized System nomenclature as published by the World Customs Organization, HS 2022 edition. It is a classification reference, not a tariff: it carries no duty rates, and it stops at six digits — the importing country adds its own beyond that.

Classification is decided by the General Rules of Interpretation and the section and chapter notes, and it is the importing country’s customs authority that makes it binding.

5509.32 FAQ

5509.32 covers yarn; (not sewing thread), multiple (folded) or cabled, of synthetic staple fibres, containing 85% or more by weight of acrylic or modacrylic, not put up for retail sale. It sits under heading 55.09 (yarn (other than sewing thread) of synthetic staple fibres, not put up for retail sale) in chapter 55, Section XI of the Harmonized System.

It is the international part of it. Six digits are the same in every country that applies the Harmonized System; the importing country then extends them to eight or ten for its own tariff and statistics. Declare 5509.32 plus whatever national digits the destination’s tariff schedule adds to it.

The General Rules of Interpretation, read together with the notes to Section XI and to chapter 55. A description that reads right is not enough on its own — the notes routinely pull goods out of the chapter they obviously belong to and put them somewhere else. Where duty or licensing turns on the answer, ask the importing country’s customs authority for a binding ruling.

A wrong or missing code is one of the common reasons customs holds a container, and a hold shows up as a milestone that stops moving. Watch for it in the container tracking app, on the air waybill in the air cargo tracker, or through the tracking API.
