Chapter 73 covers articles of iron or steel, including various products made directly from iron or steel, but excludes raw materials for iron and steel smelting (Chapter 72) and mechanical and electrical products (Chapters 84-85). This chapter includes tubes, hollow profiles, wire, netting, ropes, chains, nails, screws, springs, stoves, sanitary ware, etc. Heading 7314 specifically relates to cloth, grill, netting, fencing, and expanded metal of iron or steel wire. Heading 7314 covers cloth (including endless bands), grill, netting and fencing, of iron or steel wire; expanded metal of iron or steel. Specifically includes: woven mesh, welded mesh, hexagonal mesh, fence mesh, expanded metal, etc. But excludes cast mesh plates (7325) or punched mesh plates (7326). Welded wire mesh falls under a specific subheading of this heading. First 2 digits 73: Chapter 73, articles of iron or steel. Digits 3-4: 14: Heading 7314, cloth, grill, netting and fencing, of iron or steel wire; expanded metal of iron or steel. Digits 5-6: 20: Subheading 731420, specifically welded wire mesh, grill and fencing of iron or steel wire, welded at the intersection, with a maximum cross-sectional dimension of the wire ≥3mm and a mesh size ≥100cm². Note: Subheading 731420 applies only to welded mesh, and must meet wire diameter and mesh size requirements; other welded mesh is classified under 731431 or 731439, etc. The product is welded wire mesh, welded at the intersections, and typically has a wire diameter ≥3mm and mesh ≥100cm², conforming to the description of subheading 731420. If the wire diameter is <3mm or mesh <100cm², it is classified under 731431 (galvanized or zinc-coated) or 731439 (other). If it is woven mesh rather than welded, it is classified under 731412 (woven cloth of stainless steel) or 731414 (other woven cloth of stainless steel), etc.

Product Name: Declare the specific product name, which should be clear and specific, such as "welded wire mesh", "galvanized welded wire mesh", etc., avoiding vague terms like "wire mesh". Material: Declare the specific material of the iron or steel wire, such as "low carbon steel", "stainless steel", "galvanized steel", etc., and provide the grade (e.g., Q235). Wire Diameter: Declare the cross-sectional diameter of the wire in millimeters (mm), which must be consistent with the contract and invoice. Mesh Size: Declare the mesh size, usually expressed in millimeters or centimeters, or in mesh count, but must be converted to square centimeters. Surface Treatment: Declare whether it is galvanized, plastic-coated, PVC-coated, etc., such as "hot-dip galvanized", "electro-galvanized", "PVC-coated". Use: Declare the main use, such as "for construction", "for fencing", "for farming", etc., which helps with classification. Specifications and Dimensions: Declare the width, length of the mesh sheet or roll dimensions, such as "1m x 30m". Brand and Model: Declare the brand, model, or manufacturer; if no brand, write "no brand". Example of declaration elements for customs declaration: Product Name: Galvanized welded wire mesh Material: Low carbon steel, grade Q235 Wire Diameter: 4mm Mesh Size: 100mm x 100mm (100cm²) Surface Treatment: Hot-dip galvanized Use: For construction fencing Specifications and Dimensions: 1.5m wide x 30m long/roll Brand and Model: No brand, model WWM-4 HS Code: 7314200000 Ignoring the declaration of wire diameter and mesh size, making it impossible to determine whether the conditions for 731420 are met. Misreporting woven mesh as welded mesh, leading to incorrect classification under other subheadings of 7314. Failure to declare surface treatment, which may affect subheading distinction if it is galvanized mesh (e.g., 731431).

Core criteria for classification: 1) Material is iron or steel wire; 2) Welded at intersections; 3) Maximum cross-sectional dimension of the wire ≥3mm; 4) Mesh size ≥100cm². Also need to confirm whether it has undergone surface treatment such as plastic coating or galvanizing, but surface treatment does not affect classification under 731420, only affects subsequent subheadings. If it is welded mesh of stainless steel, it is still classified under 731420, because the subheading does not limit the material. But if it is woven mesh, it is classified under 731412 or 731414. 731412 Woven cloth of stainless steel: Woven process, not welded; material is stainless steel; no wire diameter or mesh size restrictions. 731414 Other woven cloth of stainless steel: Also woven, but material is other stainless steel, distinguished from 731412 by material type. 731431 Galvanized or zinc-coated welded mesh: Welded mesh, but wire diameter <3mm or mesh <100cm², and galvanized or zinc-coated. 731439 Other welded mesh: Welded mesh, but wire diameter <3mm or mesh <100cm², and not galvanized or zinc-coated. 731450 Expanded metal: Made by punching or cutting steel plate, not welded wire, usually flat. Is it made of iron or steel wire? Is it welded at the intersections? Is the maximum cross-sectional dimension of the wire ≥3mm? Is the mesh size ≥100cm²? Are woven mesh and punched plates excluded?

How to query the import tariff for 731420? You can use the official website of the General Administration of Customs of China, the International Trade Single Window, or third-party query platforms, enter HS code 7314200000, select the importing country, origin, trade mode, etc., to obtain the MFN rate, general rate, VAT rate, etc. Note that rates may be adjusted according to policy, subject to the latest announcement. What is the difference in HS codes between welded wire mesh and woven wire mesh? Welded wire mesh is classified under 731420 (if wire diameter ≥3mm and mesh ≥100cm²), while woven wire mesh is classified under 731412 or 731414 (stainless steel) or 731419 (other). The key difference lies in the production process: welding is fusion at intersections, weaving is interlacing warp and weft. If my welded mesh has a wire diameter of 2.5mm and a mesh of 50cm², which code should it be classified under? Since the wire diameter is <3mm and mesh <100cm², it does not meet 731420. If galvanized or zinc-coated, classify under 731431; if not galvanized, classify under 731439. Material, surface treatment, and other elements must also be declared. How to fill in the mesh size during declaration? Mesh size is usually expressed in millimeters or centimeters, such as "100mm x 100mm". It can also be expressed in mesh count, but must be converted to square centimeters to ensure it meets the ≥100cm² condition. If the mesh is rectangular, provide length and width. Does 731420 include stainless steel welded mesh? Yes, 731420 does not limit the material, so stainless steel welded mesh is also classified under 731420 as long as it meets the wire diameter ≥3mm and mesh ≥100cm². However, if it is stainless steel woven mesh, it is classified under 731412. Will the HS code change after PVC coating on welded wire mesh? The first 6 digits will not change, still 731420, because subheading 731420 does not distinguish surface treatment. But if the wire diameter or mesh does not meet the conditions, coating may affect classification under 731431 (galvanized or zinc-coated) or 731439 (other); plastic coating is usually considered other coating and may be classified under 731439. What HS code-related matters should be noted when exporting welded wire mesh to the EU? Need to confirm the EU TARIC code, which may be subdivided into 10 digits. Pay attention to anti-dumping duties, quotas, and other trade measures. Also need to provide a declaration of conformity, such as CE certification. It is recommended to use the EU official database to query the latest codes and rates. How to fill in the product name during customs declaration to avoid classification disputes? The product name should be specific, such as "galvanized welded wire mesh", and indicate material, wire diameter, mesh size, surface treatment, etc. Avoid vague names like "wire netting". Also ensure that the declared elements are consistent with the contract and invoice to reduce inspection risks.
