About HS Code 2511

Heading 2511 covers natural barium sulphate (barytes) and natural barium carbonate (witherite), whether or not calcined, specifically excluding barium oxide of heading 2816. This classification is crucial for industries requiring dense, inert mineral fillers and weighting agents. Barytes, a heavy mineral, is predominantly used as a weighting agent in drilling muds for oil and gas exploration, where its high density helps control wellbore pressure. Its scope includes crude, crushed, ground, and beneficiated forms, and it may be calcined, but it must remain a natural mineral. Witherite, though less common, is used in ceramics, specialty chemicals, and as a source of other barium compounds. For trade compliance, it is vital to distinguish these natural forms from manufactured barium compounds (e.g., precipitated barium sulphate or chemically pure barium carbonate), which belong to Chapter 28. Historically, barytes has been used as a pigment since ancient times, but its major industrial application in oil drilling emerged in the 20th century. Its trade significance is directly linked to global energy exploration and industrial manufacturing. As part of Chapter 25, these minerals exemplify naturally occurring earths and stones, typically traded in bulk for industrial processing, underscoring their role as essential raw materials.

Products Under This Code

Barytes (lump), crushed barytes, ground barytes, beneficiated barytes, natural barium sulphate, drilling-grade barytes, paint-grade barytes, filler-grade barytes, industrial-grade barytes, witherite (lump), crushed witherite, ground witherite, natural barium carbonate, calcined barytes, calcined witherite, oilfield barytes, well-drilling barytes, X-ray shielding barytes, brake lining barytes, high-density barytes.

Real World Examples

A Chinese mining company exports high-grade barytes powder from Tianjin to a U.S. oilfield services company in Houston, for use as a weighting agent in drilling fluids for deepwater oil wells in the Gulf of Mexico. An Indian paint manufacturer imports natural ground barytes from Mexico, transported from Veracruz to Mundra, to serve as an extender pigment and filler in its automotive coatings. A European chemical company imports witherite from the United Kingdom, via bulk shipping, for the production of specialty barium compounds used in electronics.

Common Misclassification

Misclassification often arises when traders confuse natural barium compounds (2511) with manufactured chemical compounds. Barium oxide, hydroxide, and peroxide are explicitly excluded and belong to 2816. Similarly, precipitated (manufactured) barium sulphate falls under 2833 (sulphates), and manufactured barium carbonate under 2836 (carbonates). The key differentiator is whether the product is a naturally occurring mineral (even if ground or calcined) or a chemically synthesized or highly refined compound. The 'natural' aspect is paramount for classification under 2511.

Trade Overview

Major exporters of barytes and witherite include China, India, Morocco, the United States, and Mexico, which possess significant deposits. Key importers are countries with active oil and gas exploration industries (e.g., USA, Middle East, Russia) and robust manufacturing sectors (Europe, Southeast Asia) that utilize these minerals as fillers or in chemical production. Demand is often tied to global energy prices and industrial output. Tariffs are generally low for these industrial raw materials, often benefiting from duty-free treatment under various trade agreements, reflecting their importance in global supply chains.

Frequently Asked Questions

What is HS code 2511?

What are common misclassifications for HS code 2511?

Misclassification often arises when traders confuse natural barium compounds (2511) with manufactured chemical compounds. Barium oxide, hydroxide, and peroxide are explicitly excluded and belong to 2816. Similarly, precipitated (manufactured) barium sulphate falls under 2833 (sulphates), and manufactured barium carbonate under 2836 (carbonates). The key differentiator is whether the product is a naturally occurring mineral (even if ground or calcined) or a chemically synthesized or highly refined compound. The 'natural' aspect is paramount for classification under 2511.

Which countries trade the most under HS code 2511?

Major exporters of barytes and witherite include China, India, Morocco, the United States, and Mexico, which possess significant deposits. Key importers are countries with active oil and gas exploration industries (e.g., USA, Middle East, Russia) and robust manufacturing sectors (Europe, Southeast Asia) that utilize these minerals as fillers or in chemical production.

Tariffs are generally low for these industrial raw materials, often benefiting from duty-free treatment under various trade agreements, reflecting their importance in global supply chains.

How is HS code 2511 structured?

HS code 2511 is a 4-digit heading under Chapter 25 of the Harmonized System. The first 2 digits (25) identify the chapter, and digits 3-4 (11) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
