关于美国新增蘑菇类产品临时进口关税的重要通知特别说明：本文为美国蘑菇协会（AMI）发给食用菌分会的邮件内容，请各出口美国食用菌企业重点关注以下内容，后续将在本公众号继续发布相关信息。
译文：针对美国最高法院于2026 年 2 月 20 日作出的、撤销本届政府依据《国际紧急经济权力法》（IEEPA）所征收关税的裁决，特朗普总统发布了一项新公告，决定征收临时进口税，该措施自2026 年 2 月 24 日起生效，实施期限最长为150 天。
本次新增附加税目前设定为10%，可上调至最高15%，有效期最长为150 天。
根据《美国 — 墨西哥 — 加拿大协定》（USMCA）规定，新鲜蘑菇仍可免征该附加税。但从非 USMCA 国家进口的蘑菇制品及相关原料，包括罐头、冷冻、干制蘑菇，以及金针菇等特色进口鲜蘑菇、菌种及菌棒等，除现有关税外，还可能被征收此项附加税，具体取决于其准确的税则归类与原产国。由于关税适用与否取决于精确的《协调关税税则》（HTS）归类及原产国资质，不同产品、供应商及进口渠道所受影响将有所差异。随着相关信息更新，我们将修订《蘑菇关税表》，并在美国蘑菇协会（AMI）会员专属网站上发布。
进口蘑菇、菌种或相关原料的会员可采取以下措施：
确认每种进口产品对应的10 位 HTS 精确税号
核实原产国状态及是否符合 USMCA 适用条件
直接与报关行及贸易法律顾问沟通，确认是否适用临时附加税
在签订新采购协议、续约合同或调整采购渠道前，评估到岸成本影响
此项新举措可能对全行业近期定价、采购决策及供应链规划产生影响。进口产品及原料将根据原产国与归类不同面临成本调整。美国蘑菇协会（AMI）正持续跟踪联邦相关指引，如有进一步明确信息将及时更新。我们同时在与联邦政策制定者沟通，确保蘑菇行业的利益、供应稳定性及长期竞争力得到充分体现。
一如既往，美国蘑菇协会（AMI）将致力于在相关信息发布后，及时为会员提供有效资讯。
原文：In response to the US Supreme Court’s decision issued February 20, 2026, that struck down the Administration’s tariffs imposed under the International Emergency Economic Powers Act (IEEPA), President Trump issued a new proclamation imposing a temporary import duty effective February 24, 2026, and lasting up to 150 days.
The new surcharge is currently set at 10 percent and may be adjusted up to a maximum of 15 percent, and it may remain in place for up to 150 days.
Fresh mushrooms are still exempt under the United States–Mexico–Canada Agreement (USMCA). However, mushroom products and related materials imported from non-USMCA countries, including canned, frozen, dried, specialty imported fresh mushrooms such as enoki, and spawn/logs, may be subject to this surcharge in addition to existing duties, depending on their precise classification and origin.
Because tariff applicability depends on exact Harmonized Tariff Schedule (HTS) classifications and country-of-origin qualification, impacts will vary across products, suppliers, and import lanes. As the information evolves, we will updates the Mushroom Tariffs Sheet and make it available on the AMI members only website.
Members who import mushrooms, spawn, or related materials can:
Confirm the exact 10-digit HTS classification for each imported product
Verify country-of-origin status and whether USMCA qualification applies
Work directly with your customs broker and trade counsel to determine whether the temporary surcharge applies
Evaluate landed-cost impacts before entering new purchase agreements, renewing contracts, or adjusting sourcing.
This new action may affect near-term pricing, sourcing decisions, and supply planning across the industry. Imported products and inputs may experience cost adjustments depending on origin and classification.
AMI is actively monitoring federal guidance and will provide updates if additional clarification becomes available. We are also engaging with federal policymakers to ensure the mushroom industry’s interests, supply stability, and long-term competitiveness are fully represented.
As always, AMI remains committed to providing timely information as it becomes available and is relevant.
