Electronic Jacquard modules designed and marketed specifically for use with weaving machines are generally classified as parts of weaving machines rather than as standalone electronic equipment, because their design is specific to the loom application. However, if a module is a general-purpose programmable controller that happens to be used on a loom, it may fall under electronic machinery headings. Detailed technical documentation from the manufacturer describing the module's intended use is essential to support the classification.

High-value loom parts typically require a commercial invoice with a detailed technical description, the manufacturer's part number, country of origin, and declared customs value; a packing list; and a bill of lading or airway bill. For electronic components, an export control classification number (ECCN) determination may be needed to confirm no export license is required from the country of export. If the parts originate from a country subject to antidumping or Section 301 orders covering textile machinery components, a certificate of origin and supporting manufacturing documentation will be critical.
