How to import goods into usa?

The parties most concerned with the grey market of a good are usually the authorized agents or importers, or the retailers, of the good in the target market. Often this is the national subsidiary of the manufacturer, or a related company, which is the local licensee of the manufacturer's trademarks; rigorous prosecution of trademark laws to restrict advertisements for the product is thus a common tactic used to discourage the grey market, along with refusal to honour warranties and refusal to deal with distributors and retailers (and with commercial products, customers) that trade in grey-market goods. Local laws (or customer demand) concerning distribution and packaging (for example, the language on labels, units of measurement, and nutritional disclosure of foodstuffs) can be brought into play, as can national standards certifications for certain goods.
