Verification path
Check the order in layers, not by promise.
Where is production coordinated?
Production is arranged through a long-term manufacturing partner in mainland China. Xiamen coordinates product, schedule, quality and customer support.
Which management systems support production?
ISO 9001:2015 and ISO 14001:2015 certificate support is available for quotation review. Public wording on this site avoids claiming approvals or capacities that have not been documented for the buyer.
Which files exist at which stage?
English TDS files support product review. SDS is confirmed by product and destination with quotation. Batch COA belongs to the actual production batch and is issued with the order.
Can someone check before shipment?
Factory visits, live video audits and third-party pre-shipment inspection can be arranged for qualified OEM projects. SGS, Bureau Veritas, Intertek or the buyer's appointed agent can inspect to an agreed scope.
What commercial assumptions should be checked?
Standard references include mixed-container programmes, 15–25 working days from confirmed order and payment, T/T deposit and balance before shipment, FOB Xiamen with CFR/CIF available by quotation.
What is stated, and what still needs project verification
Capacity and market experience are stated plainly. Sensitive detail is still verified by project.
The production network has an annual lubricant manufacturing capacity of 60,000 tonnes. MOTTA products have been exported to multiple countries, and the programme has supplied OEM products for multiple international clients. We do not publish customer names, country counts or equipment lists unless they are suitable for that buyer's review file.
60,000 tonnes per year
This is the stated annual lubricant manufacturing capacity of the production network. The practical production window for a specific order still depends on product mix, pack format and current schedule.
Confirm by audit scope
Quality review exists, but detailed equipment lists should match the facility and scope being reviewed. Request the scope before inspection or tender submission.
Multiple countries and international clients
The programme has exported to multiple countries and supplied OEM products for multiple international clients. Specific references are handled case by case where confidentiality allows.
Visual checks
Photos help orientation. Verification still follows the project scope.
For a serious OEM discussion, the useful question is not whether a photo looks polished. It is whether the route can be checked: tanks, filling, laboratory review, finished-goods handling and the facility location can all be discussed before deposit.
