What Bulk Liquid Transport does

Qingdao BLT Flexitank Solution Co., Ltd., doing business as BLT (Bulk Liquid Transport), is a privately held Chinese manufacturer of one-time-use flexitanks used to ship non-hazardous bulk liquids inside standard shipping containers. Founded in 2007 and headquartered in Qingdao, China, the company operates an over 200,000 m2 manufacturing facility that it states is the world's largest in the category, and reports sales of more than 500,000 flexitanks in 2023 and a cumulative base of over 1,000 enterprise customers worldwide. Its legal entity is registered in Qingdao, China, with no disclosed parent company, subsidiaries, funding rounds, or ownership structure; the company is privately held and self-describes as founder-operated.

BLT's product portfolio centers on six specialized flexitank variants — Food Grade Liquid, Chemical, Wine, Heat-Resistant, FrosFlex Freezing-Resistant, and Truck — supported by heating-pad accessories (steam rubber hose Z/U type, steam iron tube, and 220v/380v electric), metal bars, and backing plates. Underlying technology relies on multi-layer polymer films engineered for different cargo constraints (corrosion resistance, oxygen barrier, thermal tolerance, low-temperature flexibility), produced through what BLT describes as a self-owned full supply chain from raw materials to finished product with an ID tracing system. The company carries an extensive certification stack relevant to its served industries, including ISO 9001, ISO 14001, FSSC22000, Kosher, Halal, FDA 21 CFR Part 11, EU food-grade testing, COA quality compliance, CRCC (China rail), and AAR (North American rail) certifications.

BLT generates revenue through direct enterprise sales of consumable flexitank hardware, accessories, and a layer of professional services (consultation, transportation planning, risk assessment, custom product tailoring, insurance, and after-sales support). Pricing is quote-based and not publicly disclosed; the company claims customers save at least 50% versus traditional liquid transport methods. Commercial motion is primarily direct enterprise sales with channel support from logistics partners Maersk and Hoyer, multi-language digital presence (English, Spanish, Russian, Chinese), and trade-show engagement (ICIF China 2025, CPLF2024, Breakbulk Americas). Customers span beverage, edible oil, food additive, industrial oil, and chemical verticals, with named logos including BASF, Shell, Sinopec, Dow, ExxonMobil, CNOOC, CNPC, Cargill, Coca-Cola, COFCO, Heinz, ADM, Wilmar, Wanhua, LG Chem, Celanese, Changyu, Wacker, and Xiwang Food.
