What We Supply

One Source Plastics sells rotomolded polyethylene tanks sourced directly from five authorized manufacturers: Norwesco, Snyder Industries, Chem-Tainer, Enduraplas, and Bushman. Every SKU in our catalog is the same tank the manufacturer ships from their factory — same warranty, same certifications, same tech drawings. Our job is getting you the right tank for your application with honest freight quotes and fitment guidance.

Custom Manufacturing

When a catalog tank doesn't fit, we work with our rotomold partners to source or build:

• Custom rotational molding — capacity 10 to 20,000 gallons in HDPE, LLDPE, or XLPE. Volume required for tooling investment.
• Custom fabrication — welded polypropylene / polyethylene for rectangular, irregular, or chemical-service tanks where rotomold isn't feasible.
• Fitting packages — pre-installed bulkheads, flanges, level indicators, and sight gauges to your spec so your tank arrives install-ready.
• Color matching — blacked-out, food-grade natural, UV-stabilized tinted, or high-visibility safety yellow.

Custom runs have lead times measured in weeks. Call us at 866-418-1777 with your gallonage, fluid specs, and jurisdiction — we respond with a quote within one business day.

Why One Source

• Five brands, one ship-from. Instead of chasing each manufacturer's rep, you get authentic pricing on Norwesco, Snyder, Chem-Tainer, Enduraplas, and Bushman in one place.
• Real tech drawings per SKU. Every product page includes the manufacturer's engineering drawing (PDF download). We don't guess dimensions.
• Spec-correct fitment. Accessories are cross-referenced to specific tank part numbers — we catch size mismatches before shipping, not after.
• Nationwide freight. LTL for standard tanks, oversized freight for 2,500+ gallon sizes. We quote honest liftgate and crane fees up-front.
• US-based team. 866-418-1777 reaches someone who knows the product line during business hours.
