Scrape the ECHEMI chemical marketplace by produce URL, sale-list URL, supplier shop, CAS / chemical name, or category. Export CAS, grade, purity, FOB / unit price text, packaging, supplier profile, and inquiry history as clean JSON — an ECHEMI scraper / ECHEMI API alternative for China sourcing, competitive intelligence, and MCP / Python / Node.js pipelines.

When to use this Actor

• Bulk produce offer (/produce/pr…) URLs — the most reliable path for large result volumes
• Sale-list (/searchGoods/…) and category pages (prefer page 1; deeper pages may be blocked)
• Supplier shop storefronts (/shop-…)
• CAS / name lookup via public indexes (when a matching sale list exists)
• China chemical sourcing, price/grade monitoring, and RFQ demand signals

When not to use this Actor

• Official ECHEMI Price Database / Trade Data subscriptions (paywalled)
• Live RFQ / inquiry posting automation
• Keyword URLs like searchGoods.html?keywords=… (Aliyun WAF — use SEO sale lists or indexes instead)
• Non-ECHEMI chemical portals — use sibling B2B Actors (e.g. Europages / WLW)

---

Key Features

• Produce offers — /produce/pr… with CAS, grade, purity, packaging, price text, seller profile, inquiry history
• Sale lists — /searchGoods/… and category offer cards (stable on page 1)
• Encyclopedia — /products/… substance pages with formula, synonyms, recommended offers
• Supplier shops — /shop-… storefronts with featured products and company fields
• Bulk-stable ordering — produce / detail URLs are processed before fragile listing pagination
• Fast HTTP scraping — curl_cffi + crawler-friendly requests for SEO/detail pages
• Optional enrich — upgrade listing rows to full produce details
• Residential proxy ready — sticky Apify sessions for cloud / high-volume runs

Node.js

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: process.env.APIFY_TOKEN });

const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items.filter((i) => i.recordType !== 'error').slice(0, 5));

Python

MCP and AI assistants

Use this Actor from AI tools via Apify MCP. Connect your Apify account, then call this Actor by its Store ID crawloop/echemi-scraper.

Example prompts:

• "Run ECHEMI Scraper for CAS 121-57-3 and return the top 20 offers as JSON with supplier and price text"
• "Scrape these ECHEMI produce URLs and summarize grade, purity, company, and inquiry history"
• "Chain ECHEMI Scraper then Europages Scraper: China chemical offers by CAS, then EU buyer/supplier discovery for the same chemistry"

---

Suite next step

After China offer extraction, run Europages Scraper or WLW Scraper to map European industrial buyers and suppliers for the same chemicals. A Knowde sibling Actor (Western ingredients / TDS-SDS) is planned in the same suite — link it here once Store-public.

FAQ

How do I scrape large volumes reliably?
Pass many /produce/pr… URLs (or many page-1 /searchGoods/… lists), keep maxPages: 1, enable residential proxy, and set a long enough run timeout. Produce pages are the stable bulk path.

Why not paste searchGoods.html?keywords=…?
Those keyword URLs are protected by Aliyun WAF for automated clients. Prefer /searchGoods/{slug}.html sale lists, category URLs, or CAS/name queries (resolved via public indexes).

Do all offers show a numeric price?
No. Many listings show “Get Latest Price” and require an inquiry. The Actor still returns grade, purity, packaging, supplier fields, and inquiry history when present.

Is residential proxy required?
Recommended on the Apify platform for stable cloud runs. SEO produce / encyclopedia pages often work with bot-friendly requests; residential sticky sessions help when Aliyun WAF challenges datacenter egress.

What does maxItems count?
Successful listing / produce / supplier / encyclopedia rows only. Error rows may still appear in the dataset but do not stop the run early.
