The universally accepted\u00a0<\/span>Harmonized System (HS) code for Ceramic Fiber Blankets<\/a> is 6806.10<\/span><\/strong>. <\/span>This classification falls under “Slag wool, rock wool and similar mineral wools (including intermixtures thereof), in bulk, sheets or rolls.” <\/span>However, critical regional variations exist: <\/span>India and Vietnam<\/span><\/strong>\u00a0frequently utilize\u00a0<\/span>6903.90.30<\/span><\/strong>\u00a0(Other refractory ceramic goods), while China often exports under\u00a0<\/span>6806.10.00<\/span><\/strong>. For United States imports, the specific HTS code is\u00a0<\/span>6806.10.0090<\/span><\/strong>, attracting a general duty rate of approximately\u00a0<\/span>3.9%<\/span><\/strong>, though Section 301 tariffs for Chinese origin goods may apply. Correct classification depends heavily on the aluminum-silicate content and whether the product is needled or chemically bonded.<\/span><\/p>\n

What is the Harmonized System (HS)<\/h2>\n

The Harmonized Commodity Description and Coding System is the international naming and numbering system used to classify traded goods. The World Customs Organization maintains the six-digit headings; member countries expand those six digits to produce national tariff lines (for duties, statistics and other legal matters). Because the six-digit code is the shared reference point, getting the correct six-digit heading is the first step toward consistent, legal classification. The WCO provides explanatory notes that help interpret headings and subheadings.<\/p>\n

Why ceramic fiber blankets are commonly classified under HS 6806.10<\/h2>\n

Heading 68.06<\/strong> covers \u201cslag wool, rock wool and similar mineral wools;\u2026 articles of heat-insulating, sound-insulating or sound-absorbing mineral materials.\u201d Ceramic fiber blankets made from refractory ceramic fibers (alumina-silicate fibers or similar man-made ceramic fibers) frequently share functional and physical characteristics with mineral wools: they are fibrous mats or rolls used for thermal insulation, produced in batt, blanket, sheet or roll form. Multiple customs rulings in practice have placed ceramic fiber blankets within subheading 6806.10<\/strong> for “slag wool, rock wool and similar mineral wools, in bulk, sheets or rolls.” Those rulings examine the product\u2019s fiber type, binder content, density, format and intended use to reach a decision.<\/p>\n

Country-level code examples (common national forms)<\/h2>\n

Different countries append digits to the six-digit HS heading to form national tariff lines. Below is a compact reference mapping typical codes used by traders and customs practitioners.<\/p>\n

How customs decide the correct heading \u2014 practical criteria<\/h2>\n

Classification is fact-driven. Customs officers and courts use the Harmonized System\u2019s General Rules of Interpretation plus explanatory notes and binding rulings. The following checklist captures the most decisive elements:<\/p>\n

Practical tip: submit a full technical file to customs (materials test reports, production photos, TDS, MSDS, bills of lading) with the import declaration. This cuts classification back-and-forth and reduces the chance of retrospective reclassification.<\/p>\n

Representative customs rulings and real-world precedent<\/h2>\n

Authoritative rulings help predict outcomes. The U.S. Customs and Border Protection database contains rulings that explicitly classify ceramic fiber blankets under HTS subheading 6806.10.00<\/strong>; one published ruling for a ceramic fiber blanket found the product to be within \u201cslag wool, rock wool and similar mineral wools\u201d when the blanket\u2019s properties matched mineral wool characteristics. Another ruling distinguished batt width when assigning sub-subheadings. These rulings are commonly cited by customs brokers and importers.<\/p>\n

Duty rates, trade flows and commercial considerations<\/h2>\n

Duty rates vary by country, origin and any preferential trade agreements. For example, many HTS lines in chapter 68 carry modest ad valorem rates for industrial mineral wool products, sometimes around a few percent in the United States, though preferential treatment or free trade agreements can reduce duties to zero. Importers should consult the importing country\u2019s tariff schedule and the origin country\u2019s status under trade agreements. Trade databases and shipping portals show hundreds to thousands of shipments of ceramic fiber blankets recorded under 68061000 and similar national codes, indicating that this classification is widely used in commercial trade.<\/p>\n
