Product Overview Stainless steel tanks classified under HS Code 730900 are industrial-grade vessels fabricated primarily from corrosion-resistant stainless steel alloys, designed for the storage, processing, and transport of liquids and semi-liquids across various sectors. These tanks typically feature welded or seamless cylindrical bodies with capacities ranging from a few hundred liters up to several thousand liters, incorporating polished or matte finishes to meet hygiene and durability standards. Constructed with high-grade stainless steel (commonly grades 304 or 316), they exhibit superior resistance to chemical corrosion, temperature fluctuations, and mechanical stress. Within HS Code 730900, tanks are categorized based on their structural design—stationary or portable—and surface treatment, including passivation and electropolishing. Commercially, these tanks are extensively utilized in food and beverage processing, pharmaceuticals, chemical manufacturing, and retail distribution, providing sanitary containment and controlled environments essential for product integrity. Their robust construction and compliance with industrial quality certifications position them as reliable assets in international supply chains, offering longevity and operational efficiency aligned with global trade requirements. HS Code Classification & Trade Specifications The HS Code 730900 falls under Chapter 73, which encompasses “Articles of Iron or Steel,” specifically under Heading 7309, designated for “Reservoirs, tanks, vats, and similar containers, of iron or steel, of a capacity exceeding 300 liters.” The six-digit classification 730900 precisely identifies stainless steel tanks exceeding this volume threshold, differentiating them from smaller containers or those made from alternative materials. This classification is justified by the tank’s material composition, structural capacity, and intended industrial application, consistent with the Harmonized System’s guidelines for metal containers used in storage and transport. Trade considerations include secure packaging with corrosion-inhibiting protective films or coatings, adherence to standardized palletization, and compliance with international shipping regulations to prevent contamination and mechanical damage during transit. Quality standards adhere to ISO 9001 and relevant ASTM specifications for stainless steel fabrication, ensuring traceability and conformity with WTO agreements and customs documentation protocols. Such detailed classification and trade information facilitate accurate tariff determination, customs clearance, and regulatory compliance essential for global commerce.
