What happened?
Amazon US has updated its fee-category rules, designating 3D Printers—meaning 3D printers and 3D printing pens—as a separate fee category effective October 31, 2026. Under the previous classification, these products were generally included in Business, Industrial, and Scientific Supplies. After the rule takes effect, the main printer units and 3D printing pens will be identified under the new category, while accessories such as nozzles, consumables, and printing filament will remain under Business, Industrial, and Scientific Supplies. The change affects 3D printing equipment brands, cross-border factories, professional printer sellers, and sellers that offer both complete units and accessories. Because different referral-fee categories may affect referral fees, profit calculations, Fee Preview, and advertising return on investment, sellers should monitor fee changes. Amazon also reminds sellers that each ASIN can belong to only one fee category, and the product category shown on the retail page may not be the same as the fee category. Sellers should check Fee Preview, verify ASIN classifications, and assess pricing separately for complete units, printing pens, consumables, and accessories before October 31.
What does this mean for cross-border sellers?
On Amazon US, 3D printers and 3D printing pens will move from their existing categories to a separate referral-fee category, which may affect referral fees, profit calculations, Fee Preview, and advertising return on investment. Check complete units, printing pens, nozzles, consumables, and printing filament separately to avoid ASIN-classification and pricing errors.
What should sellers do now?
- 1Before October 31, use Fee Preview this week to check each Amazon US 3D printer and 3D printing pen ASIN, and organize the classifications for complete units, printing pens, nozzles, consumables, and printing filament in a table to ensure that each ASIN corresponds to only one fee category.Profit calculator
- 2Enter Amazon US complete units, printing pens, nozzles, consumables, and printing filament separately into the profit calculator, recalculate referral fees, profit, and advertising return on investment under the new classifications, and produce an ASIN-by-ASIN pricing adjustment list for repricing and advertising review.
- 3For Amazon US listings that sell both complete units and accessories, use a break-even calculator to estimate acceptable prices under the new classifications, complete three sets of results for complete units, printing pens, and accessories, and check the profit boundaries after advertising spend.Breakeven calculator
