H2Q’s role and business contact · Manufacturer information and evidence
Specify the required solid form, purity and impurity limits, and identify the metals and formulation in your evaluation. State your trial quantity or recurring demand, with units. Minimum order quantity is confirmed individually for the grade, package and destination; there is no single minimum across this catalog.
Review BTA specifications. The reference tables do not establish current availability or an accepted order quantity.
Give your required delivery date, destination city and state, ZIP code or receiving port, and preferred delivery terms. H2Q confirms lead time, packaging, transport arrangements and delivery terms for each order in the quotation and sales contract. Qingyuan handles export procedures; import responsibilities must be agreed for the destination.
Availability and delivery timing are confirmed for the specific order; this page does not indicate U.S. inventory.

Identify the metals or alloys, operating environment and intended formulation. Agree the corrosion test and acceptance criteria for the grade under evaluation.
Provide system conditions and the other treatment ingredients, together with the metal surfaces requiring protection. Review BTA as part of the complete water-treatment formulation.
The manufacturer lists antifreeze and lubricant uses. Describe the base formulation, other additives and qualification tests; the application listing does not prove compatibility with every finished product.
Use the TDS for product review, the SDS for handling and regulatory review, and a relevant COA for batch-level checks.
Request BTA documentsNo. At least 99.8% is the purity specification in the current manufacturer TDS. Performance in a finished formulation also depends on the metals, operating conditions and other ingredients, and must be evaluated using your qualification criteria.
The published range is 5.0–6.0, but the source does not specify test dilution or temperature. Request the current method and use comparable conditions before interpreting a difference between supplier results.
The older catalogue reference says clear and colorless but does not state the alcohol type, concentration or detailed method. The current TDS does not list that test. If it is part of your purchasing specification, request confirmation rather than treating the older result as a current guarantee or universal solubility statement.
No. The current manufacturer TDS lists a 25 kg plastic woven bag. Earlier catalogue bag and fiber-drum formats are retained as separate references. Package size is not a minimum order quantity. H2Q confirms MOQ, packaging and shipment terms for the order; sample requests are confirmed by email.
