Why physical goods dominate: the manufacturing export connection
The concentration of Amazon sellers in physical product categories — tools, electronics, home goods, automotive accessories — is not coincidental. With 69.7% of storefronts registered in mainland China, the category distribution closely mirrors Chinese manufacturing export specialisations. China is the world's largest exporter of consumer electronics, small appliances, household goods, and tool accessories, and this industrial infrastructure gives Chinese Amazon sellers a structural cost advantage in exactly the categories where seller density is highest. Home & Kitchen at 10,215 sellers, Electronics at 8,587, DIY & Tools at 7,000: these are precisely the product lines where Chinese factory-direct-to-consumer strategies are most effective. For agencies, service providers, and compliance teams, this means that the categories with the most reachable sellers are also the ones where Chinese origin is most prevalent — a critical input for cross-border compliance and targeting strategies.
Service and digital categories: a smaller but distinct segment
Grocery & Gourmet Food (2,990 sellers), Health & Household (2,627), Baby Products (2,086), and Garden & Outdoors (1,002) represent categories where regulatory barriers to cross-border selling are typically higher — food safety standards, chemical compliance, and import restrictions create friction that reduces the dominance of factory-direct sellers. Office Products (2,275) and Pet Supplies (2,146) occupy a middle ground: relatively low barrier to entry, but also lower average selling prices, which creates a different competitive profile to high-ticket electronics or automotive accessories. For sales agencies and SaaS platforms targeting Amazon sellers, these mid-tier categories represent an attractive balance of addressable seller volume and categories where value-added services — listing optimisation, PPC management, compliance support — tend to produce higher return on investment for the seller. Baby Products (2,086) and Pet Supplies (2,146) are also categories where Chinese-origin sellers face stronger domestic-brand competition from Western sellers, creating pockets of the market less dominated by the 69.7% China-origin majority.

Category data as a targeting layer: what it means for list buyers
Category assignment is the single most actionable filter available when building a targeted Amazon seller outreach list. Knowing that 10,215 sellers are in Home & Kitchen, 8,587 in Electronics, and 7,000 in DIY & Tools gives list-buyers a direct mechanism for narrowing the full 67,416-storefront universe to a relevant addressable segment without wasting budget on mismatched verticals. A PPC agency specialising in electronics sellers can isolate 8,587 targets directly; a compliance firm focused on food imports can scope to Grocery & Gourmet Food's 2,990 sellers. The category layer compounds with origin filters — e.g., Chinese-origin Electronics sellers — to produce highly specific sub-segments. In the State of Amazon Sellers 2026 flagship report, the overview shows that category concentration and China-origin concentration are mutually reinforcing: the most-populated categories are also the ones with the highest proportion of Chinese-registered storefronts. This means that category-targeted campaigns aimed at the top three to five categories will, by default, be engaging predominantly with cross-border Chinese sellers — requiring messaging, compliance, and contact enrichment strategies appropriate to that audience. The practical implication for list-buyers is that a category filter alone is not sufficient for effective targeting in the top tiers: combining category with country-of-registration and review-count banding provides the most accurate addressable-market estimate before committing to outreach spend. Verified Amazon seller leads from TSI can be filtered by primary category across all three marketplaces and enriched with contact data specifically built for cross-border outreach.
Frequently asked questions
- What is the most popular category for Amazon sellers?
- Home & Kitchen is the most common primary category in the TSI dataset with 10,215 sellers, followed by Electronics & Photo (8,587) and DIY & Tools (7,000). Together, these three categories account for 38.7% of all 67,416 storefronts in the dataset. Beauty (5,364) and Automotive (3,678) are the fourth and fifth largest categories respectively.
- How many Amazon seller categories are tracked in this dataset?
- The TSI dataset covers at least 15 distinct primary categories with significant seller populations. 99.99% of the 67,416 storefronts carry a category assignment, making category one of the most complete and reliable fields in the dataset. The 15 categories range from Home & Kitchen (10,215 sellers) down to Garden & Outdoors (1,002).
- Which Amazon categories have the most Chinese sellers?
- Because Chinese-origin sellers account for 69.7% of the overall dataset, they are proportionally dominant in all leading categories, but especially in manufactured physical goods: electronics (8,587 total sellers), tools (7,000 in DIY & Tools, 3,598 in Tools & Home Improvement), home goods (10,215), and automotive accessories (3,678) — product lines directly aligned with China's manufacturing export strengths.
- Are Grocery and Food sellers well represented on Amazon?
- Grocery & Gourmet Food has 2,990 sellers in the dataset, placing it ninth overall out of 15 tracked categories. Food and consumable categories tend to have more regulatory complexity for cross-border sellers — food safety standards, ingredient labelling requirements, and import restrictions — which partially explains the lower seller density relative to tools (7,000) and electronics (8,587).
