Tantalum Etching Residue from Mexico
Tantalum etching residue is a fine particulate recovered from chemical etching baths used in circuit board manufacturing. Once dried, it consists primarily of tantalum metal in powder form and is considered waste and scrap under tariff item 8103.30.00. This material is not usable as-is and is imported for recycling or recovery of tantalum content.

Import Tips
• Ensure the residue is dried and free of hazardous etching chemicals to avoid CBSA classification as dangerous goods
• Declare the material as waste and scrap under 8103.30.00; if it contains recoverable tantalum above 99% purity, it may be reclassified as powder
• Keep records of the etching process to prove it is not usable as tantalum articles
