downhole tools factories qualified for exports
Lots of Chinese downhole tools 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.
