Dowel pin Hs Code

Dowel pin harmonized system code

Product Overview Dowel pins classified under HS Code 731829 are precision-engineered cylindrical metal pins used primarily for accurate alignment in mechanical assemblies. These components are typically manufactured from stainless steel, carbon steel, or alloy steel, exhibiting diameters ranging from 1 mm to 25 mm and lengths extending up to 100 mm, depending on application requirements. The pins undergo processes such as cold drawing, grinding, and heat treatment to achieve high dimensional tolerances (commonly within ±0.01 mm) and surface finishes that ensure corrosion resistance and mechanical stability. Within the HS Code 731829 classification, subcategories differentiate pins by material composition and surface treatment, including hardened and non-hardened variants. Commercially, dowel pins serve critical roles in sectors such as food processing equipment assembly, retail display fixtures, and industrial manufacturing lines, where precise component alignment is essential. Their value proposition lies in providing consistent mechanical fit, enhanced load distribution, and durability under repetitive operational stresses, making them integral to maintaining production efficiency and product quality. HS Code Classification & Trade Specifications The complete HS Code for dowel pins is 7318.29, where Chapter 73 covers “Iron and Steel” products; Heading 7318 pertains to “Screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter-pins, washers (including spring washers) and similar articles, of iron or steel”; and Subheading 29 specifically identifies “Other threaded articles.” Dowel pins fall under this classification due to their metallic composition and function as fastening and alignment components without external threading. Trade compliance necessitates adherence to standardized packaging—typically bulk-packed in corrosion-resistant containers or sealed plastic bags to prevent oxidation during transit—and preservation methods such as desiccant use and controlled humidity environments. Shipping considerations include secure palletization to prevent mechanical damage. Quality standards align with ISO 8734 and DIN 6325 specifications, ensuring dimensional accuracy and material integrity. Compliance with WTO and international customs protocols is maintained through precise product description and classification, facilitating smooth customs clearance and tariff application in cross-border transactions.

Dowel pin 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.
