Aluminium cap Hs Code

Aluminium cap harmonized system code

Product Overview The aluminium cap classified under HS Code 830990 refers to a metallic closure component primarily manufactured from high-grade aluminium alloys. These caps are precision-engineered to provide durable sealing solutions with corrosion resistance, lightweight properties, and thermal conductivity suitable for various container types. Typically, the product exhibits dimensional specifications compliant with international standards, including diameters ranging from 20 mm to 100 mm and thicknesses between 0.2 mm and 1.0 mm, subject to application requirements. The processing involves stamping, anodizing, and surface finishing to enhance mechanical strength and aesthetic consistency. Within HS Code 830990, subcategories encompass base metal mountings, fittings, and similar articles not elsewhere specified, underlining the aluminium cap’s classification among non-ferrous metal closures. Commercially, these caps serve critical roles in food and beverage packaging, pharmaceutical sealing, and industrial container closures, ensuring product integrity and contamination prevention. Their market positioning leverages aluminium’s recyclability and compliance with hygiene standards, offering a cost-effective and environmentally sustainable solution utilized by importers, exporters, and manufacturing entities. HS Code Classification & Trade Specifications The aluminium cap is classified under the full 6-digit HS Code 830990, where Chapter 83 denotes “Miscellaneous articles of base metal,” Heading 8309 covers “Stoppers, lids, caps and other closures,” and Subheading 830990 specifies “Parts.” This classification is justified by the product’s function as a closure component fabricated from non-ferrous metals, thereby excluding it from other categories reserved for ferrous materials or plastic closures. Trade considerations include packaging in bulk quantities or palletized cartons designed to minimize deformation during transit, with moisture-resistant wrapping to prevent oxidation despite aluminium’s inherent corrosion resistance. Standard preservation methods adhere to ISO 9001 quality management guidelines and relevant ASTM standards for dimensional accuracy and mechanical properties. Shipping requirements comply with WTO trade facilitation agreements, ensuring harmonized tariff application and expedited customs clearance. The product’s measurable attributes—such as tensile strength (minimum 90 MPa) and dimensional tolerances within ±0.1 mm—are critical for customs valuation and classification accuracy, supporting transparent international trade documentation and regulatory compliance.

Aluminium cap Chapter Note

1.- For the purposes of this Chapter, parts of base metal are to be classified with their parent articles. However, articles of iron or steel of heading 73.12, 73.15, 73.17, 73.18 or 73.20, or similar articles of other base metal (Chapters 74 to 76 and 78 to 81) are not to be taken as parts of articles of this Chapter. 2.- For the purposes of heading 83.02, the word “castors” means those having a diameter (including, where appropriate, tyres) not exceeding 75 mm, or those having a diameter (including, where appropriate, tyres) exceeding 75 mm provided that the width of the wheel or tyre fitted thereto is less than 30 mm.
