US Customs and Border Protection agents spent four days investigating Auckland timber processor Hermpac after a complaint from the US Lumber Coalition. The finding was uncomfortable. A wholesaler on America’s east coast had been routing Canadian-origin wood through New Zealand for processing before shipping it into the US. …The purpose, according to the investigation, was to dodge the punishing duties the US imposes on Canadian softwood lumber. This is the first confirmed case of a New Zealand processor being directly investigated by US Customs in connection with the Trump-era tariff regime. …The fight is no longer just about headline rates. It is now about who inspects your paperwork, and whether the value you add in New Zealand counts. …The practical takeaway is unglamorous but urgent. Review and document your origin classifications now, before a competitor files a complaint, not after Customs agents turn up.
