A:Lots of Chinese zinc alloy mortise door lock makers have got export licenses that allow the merchandise to be cleared via China Customs. This is a huge change compared to this in 1997. The producers who lack export permits are normally smaller producers who behave as technical subcontractors. They simply concentrate on creating a specific type of substance, processing or component for a bigger - and more export oriented - maker. You're expected to use producers that have export licenses or trading businesses that partner with manufacturers in the long term.
In future, we will always try our best to make high quality, popular and reliable chinese door lock products for our customers.
