It reports export activity since 2001 and accepts LC, PayPal, T/T, and Western Union.

The supplier reports ISO 9000/9001 and ISO 14000/14001 management-system certifications, more than 10 production lines, and 11–20 quality-control staff. However, the available information does not establish after-sales support, financial credibility, R&D strength, customization capability, or detailed customer performance. Trade records show several 2025 transactions involving sorting and metal-detection equipment with buyers in Mexico and the United States, but the records provide limited transaction detail.

Production capacityThe supplier reports more than 10 production lines and annual production output above the stated threshold, with 11–20 quality-control staff. However, its company type is listed as trading company, and the slices do not clarify the ownership or operational relationship between DKJL and the factory in Zibo, Shandong.

Client casesTrade records show 2025 transactions involving a metal-granule sorting machine, color sorters, and a metal detector, with buyers in Mexico and the United States. These records demonstrate some identifiable international buyer activity, but the limited number of transactions and absence of performance, repeat-order, or satisfaction evidence prevent a stronger assessment.
