Producer
Hailiang Group Co., Ltd.
Hailiang Group Co., Ltd. (SHEX: 002171, HQ Zhuji, Zhejiang Province; the world's largest copper products manufacturer by volume) produces both copper tube and brass rod at its Zhuji complex. Hailiang is a major global brass rod supplier — its brass rod production includes C36000-equivalent free-machining alloys as well as architectural and industrial brasses. US antidumping duties (AD/CVD Order A-570-964 and related orders) have been levied on Chinese brass rod including Hailiang's exports, but Chinese brass rod continues to flow into global supply chains through third-country transshipment and via Hailiang's overseas expansion. Hailiang has been named in US Commerce Department antidumping proceedings and has operated manufacturing in Southeast Asia partly to serve export markets outside the tariff scope. China's share of global brass rod production is approximately 60-65% by volume, with Hailiang and Ningbo Jintian as the two largest producers.

Concentration2024
Hailiang Group in Tongxiang Zhejiang is the world's largest copper tube manufacturer — its single Chinese production cluster processes more plumbing tube than the entire combined output of North American and European producers. US plumbing contractors are structurally dependent on Hailiang-sourced tube without being aware of it.
Hailiang Group Co., Ltd. ↗Incident2022
The US Commerce Department issued antidumping duty orders on brass rod from China (Case A-570-964, effective 2012; maintained through sunset reviews in 2018 and 2023) after finding that Chinese brass rod — including products from Hailiang Group and Ningbo Jintian — was being exported to the US at below-market prices. Commerce calculated antidumping margins exceeding 30% for some Chinese producers. The International Trade Commission (ITC) confirmed that US domestic brass rod producers (primarily Mueller Industries) were materially injured by the Chinese imports. Despite the antidumping orders, Chinese brass rod has continued to reach US plumbing fittings manufacturers through indirect channels: (1) plumbing fittings manufactured in China from Chinese rod and exported to the US; (2) Chinese rod exported to third countries (India, Taiwan, Mexico) for further processing into fittings; (3) Chinese brass rod from producers with lower antidumping margins. The antidumping orders have not eliminated the Chinese competitive pressure — they have shifted it downstream into finished fittings trade flows that are harder to track and tariff.
