| Main porcelain-producing areas |
Jingdezhen is widely associated with fine porcelain; Chaozhou is known for ceramic manufacturing; Dehua is recognized for white porcelain production. |
Factory address, business registration, production photos, and a verifiable company profile. |
The production location can help identify the supplier’s technical specialization, but location alone does not prove quality. |
| Material composition |
Common porcelain bodies are based on kaolin, feldspar, and quartz or silica, fired at high temperatures to produce a dense ceramic body. |
Material specification, technical data sheet, and information about firing temperature and glaze system. |
Ask whether the product is true porcelain, stoneware, or another ceramic body before comparing prices. |
| Typical urn capacity |
Adult urn capacities are commonly offered around 3.0–4.0 liters, while keepsake and miniature urns are often below 1.0 liter. |
Confirmed internal volume, product drawings, and dimensional tolerances. |
Select capacity according to the intended use and local funeral requirements; external dimensions do not equal internal capacity. |
| Size and dimensional control |
Commercial designs vary considerably; many adult urns are approximately 20–30 cm high, depending on shape and capacity. |
Technical drawing showing height, diameter, opening size, base diameter, and permitted tolerances. |
Confirm whether measurements are taken before or after firing, because ceramic shrinkage can affect final dimensions. |
| Lid and closure design |
Common options include threaded lids, screw-secured lids, fitted lids, and sealed lids using an appropriate adhesive. |
Closure samples, assembly instructions, replacement-lid availability, and leak or fit inspection records. |
A secure, accurately fitted lid is essential for transport, storage, and long-term display. |
| Surface and decoration |
Available finishes may include glossy glaze, matte glaze, unglazed porcelain, hand-painted decoration, decal printing, and relief work. |
Pre-production sample, approved color standard, decoration method, and sample approval procedure. |
Glaze color can vary with firing conditions; approve a physical sample rather than relying only on digital images. |
| Customization capability |
Customization may cover shape, color, logo-free artwork, engraving, packaging, capacity, and lid construction. |
Tooling quotation, artwork requirements, prototype process, sample lead time, and written approval stages. |
Complex relief, multiple colors, and special molds generally increase development time and cost. |
| Order quantity and production planning |
Minimum order quantities differ by product type; ready-made items usually require less commitment than custom-molded products. |
Written MOQ by color and design, production schedule, capacity confirmation, and raw-material availability. |
Request separate MOQs for stock items, private-label packaging, custom colors, and new molds. |
| Quality-control checkpoints |
Important checks include cracks, pinholes, glaze defects, warping, color consistency, lid fit, base stability, and packaging damage. |
Inspection checklist, approved sample, defect classification, pre-shipment inspection option, and corrective-action records. |
Agree on acceptable quality limits before production to reduce disputes over cosmetic defects. |
| Packaging protection |
Porcelain requires individual protection, cushioning, inner cartons or molded inserts, and strong export cartons. |
Packaging sample, drop-test or transit-test information, carton dimensions, gross weight, and palletization plan. |
Packaging should protect both the urn body and lid; ask how breakage claims are documented and handled. |
| Export and shipping documents |
Common commercial documents include a commercial invoice, packing list, transport document, and certificate of origin when required. |
Sample documentation, accurate HS-code support, export experience, and clearly stated shipping terms. |
Confirm import rules, labeling requirements, duties, and customs procedures in the destination country. |
| Payment and commercial protection |
A written quotation should state product specifications, quantity, unit price, tooling, packaging, shipping terms, payment schedule, and validity period. |
Signed pro forma invoice, verified bank-account details, contract, and documented sample approval. |
Avoid paying to an unrelated personal account; independently verify any bank-detail change before remitting funds. |
| Best supplier-selection method |
Shortlist several factories or trading suppliers, compare matching specifications, order samples, and inspect the first production batch. |
Business license, factory audit, product samples, customer references where available, and consistent written communication. |
The lowest quotation is not necessarily the best value; compare material, workmanship, packaging, compliance, and after-sales support together. |
