Filter paper Hs Code

Filter paper harmonized system code

Product Overview Filter paper classified under HS Code 482320 comprises high-purity cellulose-based sheets specifically engineered for filtration applications across diverse industrial sectors. These papers are characterized by their controlled porosity, uniform thickness typically ranging from 80 to 150 g/m², and high wet strength to withstand liquid passage without degradation. Manufactured through refined pulping and calendaring processes, the product exhibits consistent fiber distribution and minimal ash content, ensuring optimal clarity and retention efficiency. The HS Code 482320 encompasses subcategories including qualitative filter paper, ashless filter paper, and laboratory-grade grades, each differentiated by filtration precision and chemical inertness. Commercially, these filter papers serve critical roles in food and beverage processing, pharmaceutical manufacturing, environmental sampling, and quality control laboratories. Their compatibility with various filtration apparatus and compliance with hygiene standards position them as essential consumables in both bulk industrial operations and retail packaging formats, offering reliable performance and regulatory conformity. HS Code Classification & Trade Specifications The HS Code 482320 falls under Chapter 48 (Paper and Paperboard; Articles of Paper Pulp), Heading 4823 (Filter Paper and Paperboard; Other Paper and Paperboard for Writing, Printing or Other Graphic Purposes), with Subheading 482320 specifically assigned to filter paper. This classification is grounded in the product’s composition—predominantly cellulose fibers processed for filtration use—and its functional attributes distinguishing it from general-purpose paper products. Standard trade practices dictate packaging in moisture-resistant, anti-contamination wraps or sealed cartons to preserve fiber integrity and prevent microbial degradation during transit. Typical shipment volumes range from 10 to 25 kg bundles, adhering to international maritime and air freight regulations. Quality standards align with ISO 9001 and ISO 14001 certifications, alongside compliance with WTO trade facilitation agreements to ensure seamless customs clearance. Detailed documentation must specify product grade, basis weight, pore size distribution, and batch traceability, facilitating accurate tariff application and regulatory inspections within global trade frameworks.

Except where heading 48.03 otherwise requires, these headings do not apply to paper, paperboard, cellulose wadding or webs of cellulose fibres which have been otherwise processed. 4.- In this Chapter the expression “newsprint” means uncoated paper of a kind used for the printing of newspapers, of which not less than 50 % by weight of the total fibre content consists of wood fibres obtained by a mechanical or chemi-mechanical process, unsized or very lightly sized, having a surface roughness Parker Print Surf (1 MPa) on each side exceeding 2.5 micrometres (microns), weighing not less than 40 g/m² and not more than 65 g/m², and applies only to paper : (a) in strips or rolls of a width exceeding 28 cm; or (b) in rectangular (including square) sheets with one side exceeding 28 cm and the other side exceeding 15 cm in the unfolded state. 5.- For the purposes of heading 48.02, the expressions “paper and paperboard, of a kind used for writing, printing or other graphic purposes” and “non perforated punch-cards and punch tape paper” mean paper and paperboard made mainly from bleached pulp or from pulp obtained by a mechanical or chemi-mechanical process and satisfying any of the following criteria : (A) For paper or paperboard weighing not more than 150 g/m2 : (a) containing 10 % or more of fibres obtained by a mechanical or chemi-mechanical process, and1. weighing not more than 80 g/m2, or 2. coloured throughout the mass; or (b) containing more than 8 % ash, and 1. weighing not more than 80 g/m2, or 2. coloured throughout the mass; or (c) containing more than 3 % ash and having a brightness of 60 % or more; or (d) containing more than 3 % but not more than 8 % ash, having a brightness less than 60 %, and a burst index equal to or less than 2.5 kPa·m2/g; or (e) containing 3 % ash or less, having a brightness of 60 % or more and a burst index equal to or less than 2.5 kPa·m2/g.
