How we compare
Sourcing options
Request lab sample with TDS, SDS, and COA before bulk purchase
Ask for 125 kg or 150 kg drum quotation with FOB China port and CIF Bangladesh options
Request batch-reserved sample and matching bulk COA for quality consistency checks
Compare KR-B8A with KR-B6A and KR-96S if different softness, fullness, or stability profiles are needed
Clarify whether a silicone softener product is required instead of a lecithin fatliquoring agent
Human review
Compliance notes
Request current TDS, SDS, COA, and commercial invoice/packing list template before order placement
Confirm whether the product is supplied as non-DG under the intended shipping route and obtain written logistics classification support from the supplier or freight forwarder
Confirm HS code used for export declaration and Bangladesh import clearance alignment
Verify whether the product contains restricted preservatives, solvents, silicone components, formaldehyde donors, APEO, heavy metals, or other substances relevant to buyer compliance programs
Ask for batch-level COA showing pH, solid content, appearance, and any agreed impurity or residue checks
Confirm COC availability if required by the buyer, bank, or destination authority
No regulatory approval or import clearance outcome should be assumed from the listing alone
