custom plastic jars

Documents and checks, not claims

1. Construction still open

   Resin, capacity, neck finish and wall type must sit on one line. A carton of mixed neck finishes cannot be compared as one piece price. If a factory offers a 70-400 neck against a 58-400 request, treat that as a substitution to re-check, not as a cheaper equivalent.

2. Quantity and artwork lots

   Write pieces or cartons per specification. Mixed SKUs with different die line or color counts are separate lots. Plate, screen or pad-print setup is not hidden inside a custom unit price.

3. Food-contact and PCR files

   Ask for migration testing or food-contact statements only when the fill needs them, and only for the named resin lot. Post-consumer recycled content is a lot-tied percentage on a file, not a homepage badge. This desk does not certify FSC or GRS.

4. Decoration process choice

   Digital print versus flexographic printing or gravure printing changes MOQ and color control. State expected artwork revisions. A rewind specification applies when the decoration is a pressure-sensitive label supplied on roll, not when the jar is pad-printed. Silk screen on a curved wall needs a wrap drawing, not a flat carton die line.

5. Delivery scope

   Destination state or postal code, Incoterm and requested window stay on the brief. Carton ECT or burst strength is a shipper line. Freight that appears only after deposit is an incomplete quote.

6. Budget and supplier preference

   Optional target budget names currency and whether the figure is per piece or for the whole order. High-end, mid-range, budget or undecided describes documentation and finish preference. It is not a verified factory grade. No existing quotation is required.

Packhelp's public quote brief (observed 2026-09-15) shows a similar brief-first sequence. That page is not this site's capacity or lead-time promise. ISO ICS 55.020 (observed 2026-09-20) remains unit vocabulary only.

Review the inquiry options, then send your requirements. A longer note on keeping specifications, quantity and destination on one RFQ line is also on the procurement article.
