What payment terms do you offer?
Top offers flexible terms by partnership stage: T/T (30% deposit plus 70% against B/L copy, or 100% prior for small orders), L/C at sight for established B2B buyers, and negotiated terms for long-term contracts / LTAs. For first orders we typically require advance payment or a confirmed L/C. Samples are usually paid upfront (often net, sometimes free for qualified buyers).Tell Top your preferred method and we will align the contract; payment terms are stated clearly on the proforma invoice.
What packaging materials and sizes are available?
Packaging favors sealed, labelled, low-oxygen, food-grade formats: amber/dark glass or aluminium-lined pouches (100-500 g) for premium lots, food-grade drums (1 kg, 5 kg, 25 kg). We pack sealed, labelled, and (for long storage) with oxygen absorbers.Keep away from heat and light. Damaged-pack claims are handled per the Incoterms and our complaint process.Packs are chosen to be compatible with the material form.
Is this aglaia-odorata-concrete organic or wildcrafted?
Top sources from contracted cultivated bases; wildcrafted grade is not standard. Organic certification (EU 2018/848, NOP / USDA, or equivalent) can be arranged for dedicated lots from certified-organic sources, subject to segregated handling and lead-time / premium.Conventional (non-organic) lots are the default. Top can issue a non-GMO declaration; the COA states whether a lot is organic-certified or conventional.For organic Aglaia Odorata Concrete, tell Top early so we reserve a certified run.

Is there a national or ISO standard for aglaia-odorata-concrete?
There is no single-product GB or ISO standard for aglaia concrete. Top builds the spec on the enterprise standard Q/XXXX (built on GB 5009 series, GB 4789 series, and CAFFCI fragrance-material practice), with fragrance (not food) positioning. Must-TestSensory floral intensity, solvent residue, Pb/As/Cd/Hg, total plate count, mould & yeast.

If you need below 1 kg for lab evaluation, contact Top — we may supply a paid micro-sample.MOQ and pack options are confirmed on the quotation.
Can we set up a long-term supply agreement (LTA)?
Yes. For steady volume, Top recommends an LTA / annual framework that reserves processing slots and raw-material sourcing ahead, stabilizes price (with a review mechanism) and prioritizes your allocation.The LTA specifies grade (Q/XXXX or your spec), pack size, volume bands, lead time, quality agreement and complaint handling. Buyers under an LTA get buffer-stock priority and a dedicated contact.
What is the lead time from order to delivery?
Lead TimeBuffer-stock standard grade 3-7 days to dispatch; fresh batch 10-20 days (sourcing plus processing plus QC plus documentation).After dispatch, transit depends on incoterm (FOB Shanghai, sea to EU/US about 25-40 days; air 3-7 days). Top gives a firm dispatch date on the proforma and keeps the buyer updated.
What defines the composition of aglaia-odorata-concrete?
It is a sesquiterpene-rich floral concrete (unusual cyclocopryl esters and terpenoid florals), a fragrance class whose identity markers are unusual cyclocopryl ester florals and terpenoid compounds as the key signature. Top fingerprints GC-MS for the floral volatile fingerprint as authenticity/quality markers.Top fingerprints the volatile profile and screens for synthetic floral or solvent adulteration. Each COA reports floral intensity (sensory), solvent residue (GB 5009.262), heavy metals and micro; the identity is the natural Aglaia odorata Lour. (Chinese perfume plant) profile, not a single volatile oil.
