Sales increased by 3.45% year-on-year, down from 3.69% [2][3]. - The inventory cycle remains in a passive restocking phase due to "import grabbing," with Q1 net imports increasing by $359.26 billion year-on-year, of which over one-third ($129.71 billion) converted into inventory [2][3]. Industry Inventory Cycle - Among 14 major industry categories, 8 are in a passive restocking phase, including upstream chemical products, building materials, midstream electrical equipment, and downstream durable consumer goods [4]. - Historical inventory percentiles show that total inventory is at a historical percentile of 30.5%, with building materials at 71.5%, automotive parts at 67.8%, and paper and forestry products at 53.8% [4].

Midstream Inventory Status - Inventory status is mixed, with paper and forestry products in active restocking, while electrical equipment and transportation are in passive restocking [9][10]. - Mechanical manufacturing is currently in passive destocking [9]. Downstream Inventory Status - The current passive restocking phase is prolonged, indicating potential "import grabbing" demand [11]. - Automotive parts are transitioning to active destocking as of February 2025, while other sectors like household durable goods and textiles remain in passive restocking [11].
