Wholesale & OEM — tinvoa Solder Paste

Why buy direct

Built for buyers who need repeatable quality.

Volume pricing

Per-syringe cost drops as quantities rise. Pricing is quoted to your volume, alloy, and payment terms — no list-price markup.

Tested to IPC J-STD-005A methods

Viscosity, slump, tack and wetting are evaluated using the IPC J-STD-005A test methods. A Certificate of Conformance ships with the order.

Documentation pack

TDS, SDS, CoC, and RoHS / REACH declarations with every order. Prop 65 labels on leaded product. No paperwork chase.

Private label & OEM

Your brand on the syringe and carton, custom fill volumes, and alloy selection for OEM and contract-manufacturing programs.

Samples first

Qualify the paste on your own line before you commit. Request sample syringes of any alloy and powder type with your quote.

Worldwide shipping

The lead-free grades are not transport-regulated and ship by standard ground or air; for the two leaded grades, air and ocean classification is confirmed against SDS Section 14. We supply customs and compliance docs.

Wholesale FAQ

The common questions.

What's the minimum order quantity?

MOQ depends on the alloy, fill size, and whether it's a catalog or private-label run. We confirm the exact MOQ for your configuration in the quote — tell us your target volume and we'll work to it.

How long is lead time?

Catalog SKUs in stock ship quickly; made-to-order fills, private-label runs, and large volumes take longer. Your quote states the lead time for that specific order so you can plan around it.

Can I get samples before committing?

Yes. Request sample syringes of any alloy and powder type with your inquiry so you can qualify the paste on your own reflow profile before placing a production order.

What payment terms do you offer?

New wholesale orders are typically pro-forma (paid before production). Net terms may be available to established accounts on approval. Terms are set out in your quote and pro-forma invoice.

What documentation comes with an order?

Technical Data Sheet, Safety Data Sheet, Certificate of Conformance, and RoHS / REACH declarations. Leaded Sn63/Pb37 orders also include a Prop 65 label and lead-specific SDS. See the Hazmat Shipping Policy.

Are there restrictions on leaded (Sn63/Pb37) paste?

Leaded paste is sold wholesale-only (B2B) with confirmed business-use intent and ships with a California Prop 65 warning. It is intended for RoHS-exempt applications; buyers are responsible for confirming local import and use rules.

Do you ship internationally?

Yes for the lead-free grades — they are not transport-regulated under DOT / IATA / IMDG and ship worldwide by ground or air. The two leaded grades ship non-regulated by DOT ground; air and ocean classification is confirmed against SDS Section 14 before booking. We provide the commercial invoice (HS 3810.10), SDS, and country-of-origin and compliance declarations.
