Cross-Border E-Commerce — Managing 50+ Vendors and Hazmat Compliance Across Borders

Context

A general merchandise and beauty products reseller was expanding its cross-border e-commerce operation — selling perfumes, cosmetics, electronics, and household goods through Shopify across multiple countries. The catalog was sourced from dozens of third-party vendors, each with different data formats and update frequencies. Adding new products meant manually downloading spreadsheets, reformatting data, and uploading to Shopify — a bottleneck that slowed catalog growth.

Dozens of vendors, each with different data formats — and a growing catalog of regulated items requiring hazmat declarations for every international shipment.

Complicating things further, a significant portion of the catalog included regulated items: perfumes classified as flammable liquids, electronics containing lithium batteries, and aerosol products. Each required specific hazardous materials declarations for international shipping — requirements the team was handling manually and inconsistently.

Challenges

• Vendor data arrived in wildly different formats — some vendors offered digital feeds, others sent weekly Excel files via email, and a few only had web portals with no export option. There was no unified way to get all this product data into the catalog.
• Perfumes, aerosols, and electronics with lithium batteries required hazardous materials classifications and shipping declarations that varied by carrier and destination country. Getting these wrong meant shipments rejected at customs, returned at the seller's expense, or regulatory fines.
• Pricing across countries required calculating from vendor costs through currency conversion, tariffs, and margin targets — but vendor cost data itself was inconsistent, arriving in different currencies and units across feeds.
• The catalog was growing faster than the team could manually process. New vendor onboarding took weeks of back-and-forth to map their data into the right format, delaying time-to-market for new products.
• Shipping hazmat items required special carrier services and packaging declarations that the existing manual workflow couldn't reliably handle at scale.

Solution

We built a custom operations platform with an automated vendor pipeline and hazmat compliance engine — giving the team a single system to manage vendors, products, pricing, and fulfillment across all target markets.

50+ vendor feeds across digital sources, spreadsheets, and web portals — all normalized into one catalog, with new vendors onboarded in days instead of weeks.
