OEM Sea Container Cost Pricelist & Exporters

OEM container factory quotations are calculated using a transparent engineering bill of materials (BOM). The dominant cost variables include:

• Steel Mass and Metallurgy: Total weight of Corten-A (SPA-H) steel utilized. Standard dry containers use between 2.1 and 3.9 metric tons. Heavier corrugation (2.0mm vs 1.6mm) or reinforced floor crossmembers increases base steel costs linearly.
• Floor Specifications: Standard certified 28mm Apitong hardwood plywood from certified sustainable origins versus pressed bamboo composite boards or heavy checker-plate steel floors.
• Custom Tooling & Door Geometry: Standard double-wing rear end doors require standard production line clamping. Adding full side-opening doors, interior roll-up shutters, or multi-compartment dividers requires custom jig fixtures, structural headers, and finite element analysis (FEA) testing.
• Coating System: Multi-layer waterborne coatings applied at 100–120 microns DFT versus extreme-duty C5-M offshore marine zinc-silicate coatings.

While standard ISO containers conform to ISO 1496-1 and carry a CSC (International Convention for Safe Containers) safety approval plate, they are strictly rated for vertical multi-stack container ship cell guides and flat quayside handling. Standard ISO corner castings cannot handle the dynamic snatch loads experienced when offshore supply vessels (OSVs) operate crane transfers in heavy swells.

In contrast, DNV 2.7-1 / EN 12079 offshore baskets and cargo carrying units (CCUs) require primary structural steel with guaranteed Charpy V-Notch impact toughness down to -20°C (or -40°C for Arctic operations). The frames feature welded pad eyes, primary corner posts designed for dynamic multi-point sling lifting, and undergo 2.5x gross weight dynamic drop and tilt testing observed by classification surveyors (such as DNV, Bureau Veritas, or Lloyd's Register).

Overseas buyers have two primary options for international positioning from our Tianjin or Suzhou manufacturing bases:

• One-Way Free Repositioning (SOC - Shipper Owned Container): We coordinate with international ocean carriers and freight forwarders to load commercial cargo into your new containers for their maiden voyage. In most cases, ocean shipping lines pay a small per-diem or move the container freight-free to your target discharge hub (Rotterdam, Hamburg, Los Angeles, Melbourne, Durban), effectively eliminating dead-freight positioning costs.
• Empty Dedicated Vessel Booking / Flat-Rack Stacking: For specialized custom units (mini containers nested together, offshore half-height baskets, or insulated houses) that cannot carry standard commercial freight, units are nested inside 40HC dry containers or banded as certified ISO bundles (e.g., 4 nested mini units shipped as 1 standard TEU).

Every production batch follows an ISO 9001 and IICL (Institute of International Container Lessors) quality assurance protocol before issuance of the CSC safety approval plate. The process comprises:

1. Mill Sheet Verification: Chemical composition and yield strength testing of raw Corten steel coils.
2. Weld Integrity Testing: Ultrasonic and magnetic particle inspection across high-stress corner castings and rail splices.
3. High-Pressure Weatherproof Light & Water Test: Each finished container undergoes an enclosed high-intensity light inspection, followed by a continuous 2-bar water spray test across all door seals and seams to verify IP56 weatherproofing.
4. Reefer Pre-Trip Inspection (PTI): Refrigerated containers undergo automated 6-hour diagnostic cycles testing compressor pressures, defrost cycle integrity, temperature pulldown rates (-20°C verification), and airflow sensor calibration.

Yes. In addition to brand-new OEM/ODM builds, we maintain standing depots of second-hand containers at major coastal hubs across China (Tianjin, Qingdao, Shanghai, Ningbo). Used inventory is categorized into three strict commercial grades:

• IICL-5 Condition (approx. 90% new): Light cosmetic use, minor surface marks, no structural rust, doors seal tightly, structural square verified. Recommended for long-term ocean shipping and corporate asset leasing.
• Cargo Worthy (CW): Structurally sound, wind and watertight (WWT), valid CSC plate suitable for international ocean transport, with cosmetic blemishes, minor surface rust patches, and typical handling dents.
• As-Is / WWT (Wind & Watertight): Retired from active deep-sea container ship stacking; fully watertight with functional doors. Highly cost-effective for static ground storage, farm tool storage, or low-cost architectural conversion.
