HS Code 64.01 – Footwear; waterproof, with outer soles and uppers of rubber or plastics, (uppers not fixed to the sole nor assembled by stitch, rivet, nail, screw, plug or similar)

HS code 6401 is a 4-digit heading in the Harmonized System that covers: Footwear; waterproof, with outer soles and uppers of rubber or plastics, (uppers not fixed to the sole nor assembled by stitch, rivet, nail, screw, plug or similar). Heading 6401 covers a very specific category of footwear: 'Footwear; waterproof, with outer soles and uppers of rubber or plastics, (uppers not fixed to the sole nor assembled by stitch, rivet, nail, screw, plug or similar)'. The defining characteristics are triple-layered: true waterproof functionality, both the outer sole and upper must be made entirely of rubber or plastics, and crucially, the upper cannot be attached to the sole by traditional methods like stitching, riveting, or nailing. This construction method typically implies a molded or vulcanized construction, where the sole and upper are essentially one continuous piece or seamlessly fused. This heading primarily encompasses utility footwear designed for protection against water, mud, and harsh environments. The scope is generally limited to items like rain boots, overshoes, and certain types of protective industrial or agricultural footwear. It excludes footwear where the upper is of a different material (e.g., textile or leather) or where the upper is attached via stitching. The 'waterproof' criterion is also paramount, differentiating it from similar-looking non-waterproof rubber/plastic footwear. For trade compliance, correctly identifying the material composition of both sole and upper, along with the manufacturing method and waterproof claim, is critical to avoid misclassification. This often requires detailed product specifications from manufacturers. Historically, this category has been vital for industries requiring robust, water-impervious footwear, from fishing and farming to construction. It forms part of Chapter 64, dedicated entirely to 'Footwear, gaiters and the like; parts of such articles', establishing its place as specialized footwear.

A common misclassification error for 6401 is confusing it with 6402 ('Footwear; with outer soles and uppers of rubber or plastics (excluding waterproof footwear)'). The key differentiator is the 'waterproof' characteristic. If the footwear is made of rubber/plastics but not truly waterproof (e.g., many casual plastic sandals), it belongs in 6402. Another error is classifying footwear with textile or leather uppers (even if waterproof) under 6401; these would fall under 6403 (leather uppers) or 6404 (textile uppers). The specific construction method (not stitched/riveted) is also crucial; if the upper is attached by traditional means, it generally excludes it from 6401, even if waterproof and made of rubber/plastics.

In 2025, the top exporters of HS code 6401 in UN Comtrade data were China ($656M, 39% of world exports), Italy ($92M) and France ($79M). World exports came to about $1.7B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 6401 in UN Comtrade data were the United States ($156M, 11% of world imports), Germany ($126M) and Japan ($102M). World imports came to about $1.5B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 6401 is a 4-digit heading under Chapter 64 of the Harmonized System. The first 2 digits (64) identify the chapter, and digits 3-4 (01) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
