Classification explainer

Magnetic building tile set of 60 translucent plastic pieces for construction play, ages three and up

Country of origin for this scenario: China.

Recommended HTS code

9503.00.00.73

3 to 12 years of age

HIGH confidence. Heading 9503 expressly covers 'other toys' including construction/building sets for children. The product is a magnetic building tile set marketed for ages 3+, squarely within the EN 95.03 description of toys for amusement and construction play. CBP ruling H195956 confirms heading 9503 for children's activity/construction sets; ruling I82685 confirms 9503.70 (now folded into 9503.00) for sets including magnetic pieces used for educational/play purposes; ruling J88090 confirms 9503 for sets of magnetic tiles used in children's play. The age designation (3 and up) maps directly to statistical suffix .73 (3 to 12 years of age) within the 'Other' (non-inflatable) branch of children's products. The duty rate at the 9503.00.00 level is Free (general). No 9903 overlay footnote appears on heading 9503 in the supplied evidence, but a Section 301 China overlay should be verified with a broker.

How the classification was reached

GRI Reasoning

Step 1 – GRI 1: Heading-Level Analysis

Heading 9503 covers "tricycles, scooters, pedal cars and similar wheeled toys; dolls' carriages; dolls, other toys; reduced-scale models and similar recreational models, working or not; puzzles of all kinds; parts and accessories thereof." The EN for 95.03 group (D) explicitly covers toys intended for the amusement of persons, including educational toys and construction sets, and states that collections of articles put up clearly indicating use as toys are classified here.

A 60-piece magnetic building tile set sold for construction play for children ages 3+ is unambiguously a toy. Its primary commercial purpose is amusement and constructive play, not magnet functionality (ruling out 8505) and not office/school supply use (ruling out 3926.10).

Heading 8505 (permanent magnets) is rejected: the magnets are components embedded in plastic tiles to enable the toy's play function; the article as a whole is not presented or used as a magnet product. CBP consistently classifies composite articles where magnets serve a play function under 9503 rather than 8505.

Heading 3926 (other plastic articles) is excluded by Chapter 39, Note 2, which removes articles of Chapter 95 from Chapter 39's scope. Since the product classifies under 9503, 3926 cannot apply.

Step 2 – GRI 1/6: Subheading and Statistical Suffix Selection

Within 9503.00.00, the structure for "children's products" (as defined in 15 U.S.C. § 2052) distinguishes:

  • Inflatable toy balls, balloons and punchballs of rubber → not applicable
  • Other → applicable branch
  • Labeled or determined by importer as intended for use by persons:
  • Under 3 years of age → 9503.00.00.71
  • 3 to 12 years of age → 9503.00.00.73 ✓ (product is labeled ages 3 and up)
  • Other → 9503.00.00.90

The product is labeled "ages three and up," placing it squarely in the 3-to-12 bracket (suffix .73). The "Other" suffix .90 would apply to articles not qualifying as "children's products" under 15 U.S.C. § 2052 or to adult-targeted toys; a 60-piece building tile set for age 3+ is a children's product.

Step 3 – Duty Rate

The general (MFN) rate for 9503.00.00 is Free, as shown in the verified HTS row. Column 2 ("other") rate is 70%. No 9903 footnote overlay appears on heading 9503 in the supplied HTS evidence; however, Section 301 China tariff applicability (Chapter 99 overlays) should be independently verified, as toys from China have been subject to Section 301 List 3/4A actions.

Step 4 – Ruling Analogues

  • H195956: CBP classified a children's Science Kit (construction/educational toy set) under 9503.00.0073 — directly on-point for the statistical suffix.
  • I82685: CBP classified "Now I Know My 1,2,3's" (book + 100+ magnetic pieces including color tiles, number tiles, pattern blocks) under 9503.70 (now reorganized into 9503.00.00) — confirms magnetic tile sets for children are toys under 9503.
  • J88090: CBP classified "Bears in the Kitchen" and "Dress Up Bears" — sets with magnetic tiles used in children's play — under 9503.70 (now 9503.00.00) — confirms magnetic tile play sets classify as toys.
  • 964596: CBP analyzed sets of translucent plastic geometric shapes (polygon sets, tangrams) and classified them under 3926.10 as school supplies only where they were exclusively used in formal education without toy character; the magnetic building tile set here is sold as a consumer toy, distinguishing it from that outcome.

Step 5 – Cost/Duty Impact

| Declared unit value | $9.40 |

| Annual units | 8,000 |

| Annual import value | $75,200 |

Cited CBP rulings

Every ruling below was fetched from CBP’s public CROSS database and verified to exist before this page was published. Links go to the official ruling text.

  • H195956

    What it classified: Children's 'Science Kit' — a set of educational/construction materials for children age 8+, including magnets, marbles, balloons, and other items packaged as a toy set

    Why it’s analogous: CBP classified a multi-component children's activity/construction set under 9503.00.0073 (children's products, other toys, ages 3–12), establishing that sets of items put up as toys for children's amusement and construction play belong in heading 9503 at that statistical suffix

  • I82685

    What it classified: 'Now I Know My 1,2,3's' — a children's set comprising a hardbound book plus over 100 magnetic pieces (color tiles, number tiles, pattern blocks, counters, brick bars) for learning and play

    Why it’s analogous: CBP classified a set of magnetic tiles and pieces used for children's play under 9503.70 (now 9503.00.00), directly supporting that magnetic tile sets for children are toys under heading 9503 rather than permanent magnets (8505) or plastic articles (3926)

  • J88090

    What it classified: 'Bears in the Kitchen' and 'Dress Up Bears' — sets consisting of magnetic panels and magnetic tiles used for children's manipulative/imaginative play

    Why it’s analogous: CBP classified sets of magnetic tiles used in children's play under 9503.70 (now 9503.00.00), confirming that the magnetic character of tiles does not redirect classification away from heading 9503 when the article's primary purpose is children's amusement

CodeDescriptionGeneral rateNote
8505.19.30.00Other4.9%Permanent magnets — other (not flexible, not metal): general rate 4.9%, other 45%, with 9903.88.03 overlay flag. Applicable only if CBP were to find the magnets constitute the essential character of the article under GRI 3(b). Rejected here because the product's primary commercial purpose is children's construction play, not magnet functionality, and CBP rulings I82685 and J88090 confirm heading 9503 controls for magnetic tile play sets.
9503.00.00.90Tricycles, scooters, pedal cars and similar wheeled toys; dollsʼ carriages; dolls, other toys; reduced-scale (“scaleˮ) models and similar recreational models, working or not; puzzles of all kinds; parts and accessories thereofFreeStatistical suffix for 'Other' toys not classifiable as children's products under 15 U.S.C. § 2052, or for adult-targeted toys. Applicable if the importer does not label or determine the product as intended for ages 3–12 within the children's product definition. Since the product is labeled ages 3 and up, suffix .73 is preferred; .90 is the fallback if children's product status is disputed.
3926.10.00.00Office or school supplies5.3%Office or school supplies of plastics: general rate 5.3%, other 80%. Applicable only if the product were exclusively used as a formal school teaching aid rather than a consumer toy — rejected because Chapter 39 Note 2 excludes articles of Chapter 95, the product is sold as a toy, and ruling 964596 classified similar translucent plastic geometric shapes as school supplies only where no toy character was present.
