SourceRadar — China's Bestsellers, Before They Hit TikTok

See what's exploding in China —
4–12 weeks before it hits TikTok.

Ad-spy tools show you products after your competitors start running ads. Alibaba shows you 200 million listings. We run a two-sided radar: the China side reads what's already proven on Douyin and 1688; the Western side verifies each pick against daily Google Trends momentum. Then we hand you the numbers that actually decide a purchase order: factory-vs-retail spread, lifecycle stage, landed cost under 2026 tariffs, and the certification list — before you wire a deposit.

Why this isn't another Alibaba

📡

China-first signal, not ad-spy lag

Bestsellers ignite on Douyin and 1688 first. Ad-spy tools (Minea, PipiAds) only see a trend once Western ads run — when early movers are already 4–8 weeks in. We read the Chinese side of the wall.

💰

Three-tier pricing on every card

1688 factory price vs Alibaba listing vs US/EU retail. The 20–30% gap between 1688 and Alibaba is real, documented — and invisible unless you read Chinese. We print it, plus the 1688 search term to copy-paste.

🚦

Lifecycle honesty, live-verified

Every pick is graded early window / growth / saturated — and cross-checked daily against Google Trends momentum (↗ rising / → stable / ↘ cooling). Tools that recommend already-dead trends are the #1 trust failure in this space; our grades come with the curve to prove them.

🧮

Landed cost under 2026 tariffs

The old "landed ≈ FOB × 1.3" rule is dead. Our per-product calculator models EXW → tariff (33%+ default) → freight → landed unit cost → real margin at your target retail.

🛃

Compliance passport, US & EU

CE, FCC, FDA, EN71, UN38.3, GPSR responsible person — flagged per product with a difficulty grade, before you commit. High-difficulty certs aren't a bug: cleared early, they're your moat.

🎯

Curation, not a catalog

A short list of deeply-researched cards beats 200M listings and 700M-product databases. Every pick has verified China-side volume, white-label potential, and a path through Western customs.

How this pays for itself

Transparent model: free discovery brings you in, decision data is the subscription, execution is the service. No pay-to-play listings — suppliers can't buy a spot on the radar, which is the whole point.

Buyer playbook (2026 edition)

Bulk import beat direct mail. With de minimis gone (US, Aug 2025) and the EU's €150 exemption ending Jul 2026, sea-freight bulk into a domestic warehouse is the structural winner. Price everything at landed cost, not EXW.

Ask for FOB, not EXW. Under EXW you pay inland China trucking and export clearance — the classic first-order surprise. Small buyers should insist on FOB quotes.

Certify before the PO, not after. Lab testing (CE/FCC/EN71/ASTM) takes 2–6 weeks and $300–3,000. Amazon now suppresses toy listings without annual tests. Start testing with your sample order.

Badges aren't vetting. "Gold Supplier" is a paid membership tier. Third-party factory audits and pre-shipment inspection ($200–350/day) are the only real assurance — 10–15% of FBA-bound shipments contain defects that trigger returns.

Pay 30/70, inspect before the 70. Deposit 30%, balance after passed pre-shipment inspection against a written spec sheet with AQL sampling.

Respect the calendar. Summer SKUs are ordered by February, Q4 gifting SKUs by August. Each card shows its order-by month — miss it and you're funding next year's inventory.

Saturated ≠ forbidden, but demands an angle. Red badges mean you need a bundle, spec upgrade, accessory play, or an under-served market (often the EU) — never a price war.

Own a consumable backend. Filters, brush heads, tea refills, paper rolls: the picks with repeat-purchase attachments compound; one-shot products don't.
