Check the tariff classification for a pre-filter for a swimming pool skimmer.

New regulation

A new regulation was published on 06/08/2025 and entered into force 20 days after this date.

Reg. 2025/1556

This is considered a change in Northern Ireland practice.

Description of the goods

Disposable article, measuring approximately 28 cm (length) × 12 cm (width), made-up of a circular densely crocheted textile fabric of man-made fibres.

On one end, the article is closed with a seam. On the other end, the article has an opening with a highly elasticated hemmed edge of approximately 3 cm width.

At importation, the article is presented as a pre-filter; a sort of filter lining for skimmer baskets (baskets of plastics having a net-like structure; the baskets are inserted into the openings that drain a swimming pool in order to catch leaves and dirt before the water is guided to the pool filter).

Classification (Combined Nomenclature (CN) code)

5911 90 99

Reason

Classification is determined by general rules 1 and 6 for the interpretation of the Combined Nomenclature, Note 7(d) to Section XI, Note 8(b) to Chapter 59 and by the wording of CN codes 5911, 5911 90 and 5911 90 99.

Due to the elasticity and diameter of the hemmed edge the article is suitable for use in skimmer baskets of different diameters. Due to its elongated shape and flexible material the article lines the baskets completely. The densely crocheted yet porous (for efficient water filtration) textile fabric, resistant to water and chlorine, is suitable to filter dirt and debris out of the water of a swimming pool. The article consequently presents particular objective characteristics that identify the article as being for use inside skimmer baskets in order to filter dirt and debris out of the water of a swimming pool within the meaning of Note 8 (b) to Chapter 59. (See also the first paragraph of the Harmonized System Explanatory Notes to heading 5911).

Therefore, the article is to be classified under CN code 5911 90 99 as textile products and articles, for technical uses, specified in Note 8 to Chapter 59.
