Mixed models, small order but urgent requirement. COC was included in the email. Overall, a reliable and stable sourcing channel for NSK bearings.

Ordered TIMKEN tapered roller bearings bulk qty for resale. Price still workable for distributor margin. Supplier helped with export docs and customs clearance support.Some items had anti-rust oil little heavy, but actually better for sea shipment. Genuine products, no doubt. We continue business soon.
