Package and route

Packing notes

Standard packing stated as 25 kg/bag or jumbo bag.
Source page lists package size around 116 cm x 112 cm x 92 cm with gross weight around 1006 kg for bulk pack; confirm final pallet, liner, and bag configuration.
Request moisture-resistant inner liner and export-worthy palletization if ocean freight is required.
Confirm whether neutral, OEM, or supplier-branded labels are available for destination-market import requirements.
Ask supplier to confirm net weight, gross weight, pallet count, and container loading quantity before issuing purchase order.

Applications and sourcing options

Check whether this product fits the buyer's actual application.

Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.

Use context

Third-party pre-shipment inspection for quantity, packing, sampling, and document checks

Human review

Compliance notes

Verify CAS 1308-38-9 and Cr2O3 identity against COA, SDS, invoice, packing list, and customs documents.
Request current SDS in GHS format and confirm transport classification with the freight forwarder before shipment.
Confirm whether the product is classified as non-DG or DG for the intended route and destination; do not rely only on marketplace listing data.
Supplier page claims ISO 9001:2015, ISO 14001:2015, ISO 45001, RoHS compliance, and REACH declaration; request current certificates or declarations for file review.
Chromium compounds may be subject to destination-specific occupational, environmental, waste, or product-content controls; importer should verify local requirements before ordering.
Request heavy metal and soluble chromium data where the material will be used in ceramics, electronics, pigments, or customer-regulated applications.
No regulatory approval, import clearance, or application suitability is guaranteed by the listing; buyer should conduct destination-specific compliance review.
