What is the HTS code for a fiberglass swimming pool shell?

HTS code

9506.99.5500

CBP classified fiberglass in-ground swimming pool shells under HTS 9506.99.5500 in ruling N357680. That line covers swimming pools and wading pools and their parts and accessories, and CBP found the shells named there rather than among other articles of plastic.

The Product

  • Three fiberglass swimming pool shells (Lagoon, Haven and Cove), molded from fiberglass-reinforced polyester resin and finished with a gel coat.
  • Each is a single molded structure for permanent in-ground installation, intended to hold water when installed.
  • Imported without pumps, filters, piping, lighting, drains, ladders, skimmers or any mechanical or electrical components.
  • Sizes run from 5.00 x 2.50 x 1.40 meters (17,500 liters) to 7.00 x 3.50 x 1.40 meters (34,300 liters), with shells about 3.17 to 3.50 mm thick.

CBP's Ruling

ItemHTS codeCBP's description of the line
Fiberglass swimming pool shells: Lagoon, Haven and CoveHTS 9506.99.5500Articles and equipment for general physical exercise, gymnastics, athletics, other sports (including table-tennis) or outdoor games, not specified or included elsewhere in this chapter; swimming pools and wading pools; parts and accessories thereof: Other: Other: Swimming pools and wading pools and parts and accessories thereof

Explanation

Heading 9506 provides by name for swimming pools and wading pools and their parts and accessories, and CBP found the fiberglass shells named there. Chapter 39 note 2(y) says chapter 39 does not cover articles of chapter 95, so the shells stay out of chapter 39.

CBP placed all three shells, the Lagoon, Haven and Cove, on 9506.99.5500, the line under that heading for swimming pools and wading pools and their parts and accessories.

Headings CBP ruled out

  • Heading 3926 (other articles of plastic): The request proposed this heading, but chapter 39 note 2(y) excludes articles of chapter 95, and the shells are named in heading 9506.

Does this apply to your product?

It likely does if you can answer yes to each of these:

  • Is it a swimming pool shell, a single molded structure that holds water once installed?
  • Is it molded from fiberglass-reinforced polyester resin and finished with a gel coat?
  • Is it made for permanent in-ground installation?

A no to any of them can mean a different code. A licensed broker can classify your product.
