Flange|HS Code

Flange harmonized system code

Product Overview A Flange, classified under Harmonized System (HS) Code 7307, is a crucial industrial component primarily used to connect pipes, valves, pumps, and other equipment to form a piping system. These flanges are typically plate-shaped or ring-shaped and are designed to join two sections of a physical system together through bolting. HS Code 7307 specifically delineates flanges of iron or steel. The key characteristics of these flanges include their physical specifications like diameter, thickness, material grade, and the type of flange (e.g., slip-on, weld neck, blind, socket weld, threaded, lap joint, etc.). Each of these subcategories serves unique purposes in different commercial applications, ranging from food service and processing industries to retail sectors. The value proposition of flanges under HS Code 7307 lies in their robustness, durability, and versatility, offering competitive advantages in various industrial applications. HS Code Classification & Trade Specifications HS Code 7307 falls under Chapter 73 (Articles of Iron or Steel), Heading 07 (Tube or pipe fittings (for example, couplings, elbows, sleeves), of iron or steel). The 6-digit code 7307.00 provides a more specific classification for the same. The rationale behind this classification is that flanges are tube or pipe fittings made from iron or steel. Trade considerations for these flanges include standard packaging in wooden crates or pallets to prevent damage during transit. Depending on the buyer's location and the product's final application, specific preservation methods may be required to prevent rusting or corrosion. Shipping requirements typically involve secure fastening and padding to protect the flanges and maintain their integrity. Quality standards for flanges under this HS code are stringent, often requiring ISO 9001 certification or equivalent quality management systems. The specifications such as pressure rating, facing type, material grade, and dimensions are also critical quality attributes that need to be maintained in compliance with international trade standards.

Flange Chapter Note

1.- In this Chapter the expression “cast iron” applies to products obtained by casting in which iron predominates by weight over each of the other elements and which do not comply with the chemical composition of steel as defined in Note 1 (d) to Chapter 72. 2.- In this Chapter the word “wire” means hot or cold-formed products of any cross-sectional shape, of which no cross-sectional dimension exceeds 16 mm.
