GraceBoroChoosing a glass container OEM supplier is a decision that affects your brand quality, compliance and margin for years. The right factory is a partner; the wrong one becomes a recurring headache. Here are the ten questions every importer, distributor and private-label brand should ask before signing.
1. What is your production capacity and monthly output?
Capacity tells you whether the supplier can scale with you. Ask for monthly unit output per category (containers, baking dishes, lids) and current utilization. A factory running at 95% capacity cannot absorb your growth spikes. GraceBoro operates flexible lines sized for both standard runs and custom OEM volume.
2. Which certifications do you hold, and can you show documentation?
Verbal claims are worthless. Require certificates, not screenshots of logos. At minimum: ISO 9001 (quality system), FDA (USA), LFGB (Europe, stricter than the EU baseline) and SGS (independent material testing). See our full list on the certifications page.
3. What is your minimum order quantity (MOQ)?
MOQ drives your working capital. Standard MOQ at GraceBoro starts at 1,000 units per item, with flexible terms for mixed containers and custom OEM projects. Confirm whether MOQ applies per SKU, per design, or per shipment.
4. What are your real lead times, including tooling?
Standard items ship in 15–25 days; custom OEM orders run 25–35 days after confirmation. The longest step is usually first-artwork approval, not production. Always ask for lead time broken down into tooling, sampling, and bulk production.
5. Can you provide factory audit reports?
Ask for a recent third-party audit (e.g. SGS, Bureau Veritas) or invite your own inspector. A transparent supplier shares audit summaries, floor photos and machine lists without hesitation.
6. What material testing do you perform?
For borosilicate, request thermal-shock test data (surviving freezer-to-oven swings) and heavy-metal / leachables test reports. These protect you from recalls in regulated markets.
7. Do you support OEM, ODM or both?
OEM means you bring the design; ODM means the factory's proven molds adapted to your brand. Many buyers start ODM and graduate to custom OEM. Our full OEM / ODM service covers custom shapes, sizes, lids, logo printing and retail packaging.
8. What customization is actually available?
Get specifics: shape and compartment options, lid materials (BPA-free plastic, stainless steel, child-friendly), decoration (pad / screen printing, laser etching) and packaging (gift boxes, blister packs, promotional bundles).
9. How do you handle quality control and defects?
Ask about inline inspection, AQL levels, and the defect-replacement policy. A mature supplier documents QC at receiving, in-process and final audit stages.
10. What are your logistics terms and incoterms?
Clarify FOB vs EXW vs CIF, who books freight, and how container loading is handled. Smooth logistics reduce the risk of demurrage and damaged goods.
