100% California SJV Pima Cotton: Full Chain-of-Custody Traceability


Not all cotton is created equal. Every thread of our Pima collection starts in California's San Joaquin Valley (SJV)—grown by J.G. Boswell Company and spun by Sanyang Textile. Below is our complete, verifiable chain of custody: official government certifications, commercial invoices, and shipping bills documenting our fiber every step of the way.

Authentic quality starts with grower directness. We partner directly with J.G. Boswell Company in Corcoran, California—an agricultural leader producing legendary extra-long staple (ELS) cotton since 1925. This sales confirmation establishes our official crop allocation, guaranteeing genuine California San Joaquin Valley Pima cotton with industry-leading fiber length, tensile strength, and softness.

We believe traceability requires official legal backing, not just brand claims. Sworn before the Inglewood Chamber of Commerce under California state law, this Certificate of Origin legally authenticates that our raw cotton (2,262 bales / over 1.1 million lbs) is 100% cultivated and harvested within the United States.

Before any raw fiber departs U.S. shores, it must pass rigorous federal standards. The United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service inspects every single bale, certifying that our SJV Pima fiber (Gossypium sp.) is completely pest-free, biologically pristine, and fully compliant with international plant health regulations.

A transparent supply chain leaves no gaps in documentation. This verified commercial invoice from J.G. Boswell explicitly confirms the delivery of 2,262 bales of genuine California SJV Pima Cotton, detailing exact staple grades (GC2-2-48, Micronaire 3.5/4.9 NCL) consigned directly to our spinning partner, Sanyang Textile Co., Ltd.

Every pound of yarn is accounted for down to the individual shipping container. This signed packing list ties directly to Contract No. 222087, detailing 516,594 kg of net California SJV raw cotton inspected and cleared for export at the Port of Los Angeles.

From Los Angeles directly to Qingdao aboard Ocean Network Express (ONE), our cotton moves under a single continuous Bill of Lading straight into the clean spinning facilities of Sanyang Textile. No middlemen, no third-party mixing—just pure California SJV Pima spun into the ultra-fine yarns that make our socks.
