SITCSection 6
U.S. imports of ceramic wares for technical, laboratory, agricultural, and transport use (SITC 66391) totaled $108.6M in July 2026, traded with 47 countries.
Importers of Ceramic Wares for Technical, Laboratory, Agricultural, and Transport Use paid $10.1M in duties in July 2026 — an effective duty rate of 13% on $75.1M in dutiable value, based on actual customs collections rather than the published tariff schedule. Ceramic Wares for Technical, Laboratory, Agricultural, and Transport Use imports of $108.6M in July 2026 ran 18% above the year-to-date monthly average of $92.4M.
Last updated: July 2026 dataLaboratory crucibles, chemical-process vessels, agricultural ceramic receptacles, and ceramic transport containers occupy a specialized niche where material purity, chemical inertness, and dimensional precision matter as much as price. These technical ceramics — distinct from decorative or tableware ceramics — serve pharmaceutical manufacturing, semiconductor processing, and industrial chemistry, where contamination from the container itself is a process risk. Classification here requires that the article's primary function be technical, agricultural, or transport/packing use, distinguishing it from the broader NES ceramic articles heading.

Technical-use ceramic wares are defined by their functional role in laboratory, chemical, agricultural, or transport/packing applications — not by decorative or domestic use. The article's design, material specification (e.g., high-purity alumina, porcelain with defined chemical resistance), and intended end-use environment are the primary classification criteria. Importers should retain end-use documentation and product data sheets to support the technical-use classification.
While ceramic wares themselves are not subject to mandatory admissibility review by FDA or other agencies purely on the basis of material, those destined for use in pharmaceutical manufacturing environments may need to meet specific purity and traceability standards required by the end-user's quality system (e.g., USP or ISO standards). Import classification and end-use compliance are separate obligations, and buyers should confirm specification requirements with their procurement and quality teams.
