About HS Code 2520
Heading 2520 encompasses gypsum, anhydrite, and various plasters, all critical raw materials primarily for the construction industry. Gypsum, chemically hydrated calcium sulfate, is a soft sulfate mineral widely used. Anhydrite is its anhydrous counterpart, also calcium sulfate. The heading specifically includes 'plasters' consisting of calcined gypsum or calcium sulfate, explicitly allowing for them to be colored or to contain small quantities of accelerators or retarders to control setting times. This scope covers the raw mineral as well as its calcined powder forms, which are the basis for a wide range of plaster products. It excludes highly processed gypsum articles like plasterboard, which fall under different headings. Key sub-categories include raw gypsum rock, crushed anhydrite, plaster of Paris, building plaster, and molding plaster. Accurate classification under 2520 is crucial for trade compliance, affecting tariff rates, import regulations, and adherence to specific building material standards. The historical significance of gypsum dates back to ancient civilizations using it for plaster and mortar. In modern trade, its demand is directly tied to global construction activity, particularly in residential and commercial building. This heading is firmly rooted within Chapter 25, which focuses on non-metallic mineral products in their natural or minimally processed states, serving as fundamental raw materials for downstream manufacturing.
Products Under This Code
Raw gypsum rock, crushed gypsum, anhydrite lumps, plaster of Paris, gypsum plaster powder, stucco plaster, dental plaster, molding plaster, casting plaster, building plaster, agricultural gypsum, gypsum for cement production, gypsum board core material, colored plaster mixes, gypsum retarders (pre-mixed with plaster), gypsum accelerators (pre-mixed with plaster), ceiling plaster, wall plaster, floor screed plaster, lime-gypsum plaster, acoustic plaster, fire-resistant plaster, fibrous plaster, gypsum for chalk production, gypsum for sculpture, gypsum for medical casts.
Real World Examples
A large American drywall manufacturer frequently imports raw gypsum rock from Mexico, transported efficiently by rail and bulk vessels across the Gulf of Mexico, to serve as the core material for its gypsum board production. In another scenario, a European art restoration firm might source specialized, fine-grade molding plaster from Italy for intricate historical restoration projects, typically shipped via air freight or less-than-container-load (LCL) sea freight. An Indian cement producer regularly imports anhydrite from Oman as a crucial additive to control the setting time of its cement, with bulk cargo ships traversing the Arabian Sea. Furthermore, an Australian building materials supplier might import pre-mixed gypsum plaster, specifically formulated with retarders for extended workability, from Thailand, delivered in containerized shipments.
Common Misclassification
Common misclassification mistakes for 2520 often involve confusing the raw or calcined material with manufactured articles or chemically pure compounds. A frequent error is classifying finished gypsum articles, such as gypsum board or decorative plaster moldings, under 2520; these products fall under 6809. The distinction lies in the level of processing beyond simple calcination and the formation into a specific article. Another potential confusion arises with chemically pure calcium sulfate (2833), whereas 2520 covers natural gypsum or calcined gypsum that may contain impurities or small additives. Similarly, if gypsum is mixed with binders to form a prepared mastic or sealant, it would be classified under 3214, not 2520, which is limited to the basic plaster material.

Trade Overview
Major global producers and exporters of gypsum and anhydrite include China, the United States, Iran, Spain, Thailand, Mexico, and Canada, leveraging vast natural deposits. Key importers are countries with robust construction industries, such as the United States, various EU nations, India, Japan, and South Korea. Tariffs for raw and calcined gypsum are generally low or zero under most international trade agreements, reflecting their fundamental role in building materials. Trade routes are often optimized for bulk transport, with proximity to quarries and efficient logistics being critical. Environmental regulations regarding quarrying and processing are also significant considerations in the global trade of these materials.
