Renewable Energy Logistics,
From Factory to Field

Quite possibly. AD/CVD orders are in force on crystalline-silicon photovoltaic cells, whether or not assembled into modules, from Cambodia, Malaysia, Thailand, and Vietnam. Whether a specific shipment is in scope, and at what rate, depends on the product, the producer, and the country, and rates can be substantial. We confirm scope and the correct case rate before you ship so the duty is posted accurately at entry.

The Uyghur Forced Labor Prevention Act creates a rebuttable presumption that goods linked to the Xinjiang region of China are made with forced labor and cannot enter the U.S. Polysilicon, the base material in most solar cells, is a high-priority enforcement target, so the concern follows the material anywhere in the supply chain, even if final assembly is elsewhere. CBP can detain a shipment until you document a clean chain of custody. We help assemble that traceability package before goods move.

Generally no. Country of origin is determined by where a product is substantially transformed, not by the port it ships from. Routing Chinese-origin goods through a third country usually does not change their origin for Section 301 purposes, and under-declaring origin creates penalty exposure. We make a defensible, documented origin determination for each product so you stay both compliant and competitive.

These tools defer duties rather than eliminate them, which on high-duty solar cargo is a meaningful working-capital benefit. In an FTZ, duties and certain fees are not paid until goods leave the zone and enter U.S. commerce, and weekly entry can reduce processing fees on high-volume programs. We advise whether the strategy fits your import program and run the admissions and entries that make it work.

Beyond the standard commercial invoice, packing list, and bill of lading, solar imports typically need correct HTS classification, the right AD/CVD case and rate, a properly sized customs bond, a timely Importer Security Filing, and, critically, forced labor traceability documentation that chains polysilicon through wafer, cell, and module. We build and check that package up front so clearance isn't where your project stalls.

For renewable cargo, the expensive risks, AD/CVD, forced labor detentions, Section 301, and classification errors, all live at the customs border, which only a licensed customs broker is authorized to handle before CBP on your behalf. A forwarder alone moves the container; a broker clears it correctly and defends the entry. W.M. Stone is both, so freight and compliance move as one.

Those are project and dangerous-goods cargo. Wind blades, nacelles, towers, and power transformers move as out-of-gauge or heavy-lift freight on specialized vessels or flat racks, with lift planning, route surveys, and permitted oversized inland transport. Containerized battery systems and loose lithium cells ship as dangerous goods under the applicable UN classifications. See our project cargo capabilities for the heavy end of the work.
