Industrial and Scientific FBA Fees
Referral fee 12% — below the 15% default — with a $0.30 minimum, covering B2B, lab, MRO, and janitorial supplies.
Industrial and Scientific (Amazon Business, MRO, lab, and janitorial supplies) carries a 12% referral fee, below the 15% default. The discount reflects the category's B2B, bulk-purchase orientation where buyers are price-conscious and order in volume.
Fulfillment spans a wide range. Small consumables (gloves, fasteners, reagents) sit in the cheap standard tiers, while equipment, drums, and machinery push into oversized territory with much higher fees. Because the category mixes tiny high-margin parts with heavy low-margin bulk, blended fee analysis per ASIN matters more here than in most categories.
For sellers, Industrial and Scientific pairs well with an Amazon Business strategy — quantity discounts, business-only pricing, and tax-exempt buyers drive repeat volume. The 12% referral rate plus B2B stickiness can make for durable margins, but watch for hazmat-classified chemicals and compliance documentation (SDS sheets, certifications) that many industrial products require.
