What is HS Code (3920.51)? Definition, Key Points & Application in Acrylic Exports

2025-12-05

One-Sentence Definition

HS Code (3920.51) is the internationally recognized customs classification for non-cellular, non-reinforced plates, sheets, film, foil, and strip made of poly(methyl methacrylate) (PMMA), commonly known as acrylic.

Detailed Explanation

HS Code (3920.51) is part of the Harmonized System (HS) used globally to standardize the classification of traded goods. Specifically, 3920.51 covers acrylic (PMMA) sheets and related flat products that are non-cellular (not foamed), not reinforced, and not self-adhesive. This code is crucial for exporters and importers because it determines the applicable tariffs, regulatory requirements, and ensures smooth customs clearance. Using the correct HS code is essential to avoid delays, fines, or misapplied duties. For acrylic products, especially those used in displays, furniture, and packaging, 3920.51 is the standard code for customs declaration. (Source)

Real-World Application: TOYIN’s Export Process

For manufacturers like Toyin Acrylic Products Co., Ltd. (TOYIN), HS Code (3920.51) is essential when exporting acrylic sheets, display racks, or protective covers. During the export process, TOYIN must accurately declare this code on customs documents to ensure:
