A Colombian construction company ordered one 40HQ container of six lubricant types from Zhongtian as a trial order before buying in volume.
- Buyer: construction company in Colombia running excavators and road rollers
- Shipment: 1 × 40HQ to the Port of Buenaventura on the Pacific coast
- Products: 15W-40 CI-4 diesel engine oil, HM 68 hydraulic oil, 80W-90 GL-5 gear oil, L-CKD 220, HFDU 46 and lithium grease
- Documents: CoA, SDS, packing list, commercial invoice and bill of lading
- Stage: trial order to check the products, batch consistency and delivery before volume orders

| Outcome | Trial order shipped; volume orders depend on the buyer’s own checks |
The container covered every main lubrication point of a mixed construction fleet: 15W-40 diesel engine oil to the API CI-4 service category for the excavator and road roller engines, HM 68 anti-wear hydraulic oil for the excavator hydraulics, 80W-90 GL-5 gear oil for drive axles, differentials and travel reduction gears, L-CKD 220 heavy-load gear oil for enclosed gearboxes such as the slewing drive and the roller’s vibratory mechanism, HFDU 46 fire-resistant hydraulic fluid for circuits where the site specifies a fire-resistant fluid, and lithium grease in NLGI 1 and 2 for pins, bearings and chassis joints. For a construction lubricant supplier, one mixed container is the simplest way to cover a whole fleet from a single source.
A trial order answers what a CoA cannot. The CoA confirms what a batch contained in the laboratory; a trial shows whether the oil holds its grade through a full drain interval, whether the grease works in the existing fittings, whether the hydraulic oil stays clean through the system filter, whether the delivered product matches the pre-shipment CoA, and whether the supplier delivers on time with complete documents. A mixed load lets the buyer test each product in real equipment before committing to single-product volume orders.
A 40HQ is loaded to the rating on its door plate rather than to a fixed drum count. For comparison, our September 2026 shipment to El Salvador carried 130 drums across nine products, and a mixed drum and pail configuration is possible. Production lead time is 3 to 7 days for products in stock and 10 to 20 days for products made to order; ocean transit to Buenaventura comes on top.
Zhongtian, founded in 1998, has an annual capacity of 200,000 tonnes of lubricating oil at its plant in Susong, Anhui, and holds ISO 9001, ISO 14001 and ISO 45001 certificates. The engine and gear oils in this load are made to API service categories (CI-4, GL-5); we do not claim an API licence. The minimum order is 20 packaging units, trial orders below that are negotiable, and samples are available on request so a buyer can have them tested before committing to a container.
